Promising mouse study poised for clinical trials
While an effective treatment is available for combating multidrug-resistant tuberculosis, it carries serious side effects for patients. New research conducted at the Center for Tuberculosis Research at the Johns Hopkins University School of Medicine shows that lower doses of the toxic drug bedaquiline — given together with verapamil, a medication that’s used to treat various heart conditions — can lead to the same antibacterial effects as higher toxic doses of bedaquiline.
Findings could shed light on related Alzheimer's protein
Already known to cut proteins, the enzyme SPPL3 turns out to have additional talents, according to a new study from Johns Hopkins. In its newly discovered role, SPPL3 works without cutting proteins to activate T cells, the immune system’s foot soldiers. Because its structure is similar to that of presenilin enzymes, which have been implicated in Alzheimer’s disease, the researchers believe their findings could shed more light on presenilin functions, in addition to providing new insight into how the immune system is controlled.
Discovery has implications for immune system regulation
Researchers at Johns Hopkins have discovered what keeps an enzyme from becoming overzealous in its clipping of DNA. Since controlled clipping is required for the production of specialized immune system proteins, an understanding of what keeps the enzyme in check should help explain why its mutant forms can lead to immunodeficiency and cancer.
A lack of standards for public performance reports can misinform patients and health care providers, say experts from the Johns Hopkins Armstrong Institute for Patient Safety and Quality and the Northeastern University’s Center for Health Policy and Healthcare Research. The paper, published this week in the American Journal for Accountable Care, states that a lack of standards for public reports can produce conflicting information that could lead to confusion and leave patients and clinicians with little assurance about the integrity of the data provided.
Results of a small Johns Hopkins Children’s Center study show that hospitalized children given high-dose IV infusions of the antibiotic vancomycin to treat drug-resistant bacterial infections face an increased risk for kidney damage — an often reversible but sometimes serious complication.
Organizations will jointly enhance access and affordability of health care services
Officials at Highmark Health, Allegheny Health Network, Highmark Inc. and Johns Hopkins Medicine today announced the signing of a new master collaboration agreement that will complement the formal oncology collaboration that began earlier this year. These collaborations aim to leverage the collective strengths of the organizations and improve the availability and affordability of health care to Pennsylvania patients.
Decrease of “spongy” bone related to adoption of sedentary lifestyle
New research shows that modern human skeletons evolved into their lightly built form only relatively recently — after the start of the Holocene about 12,000 years ago, and even more recently in some human populations. The work, based on high-resolution imaging of bone joints from modern humans and chimpanzees as well as from fossils of extinct human species, shows that for millions of years, extinct humans had high bone density until a dramatic decrease in recent modern humans.
Points to new strategy to reduce allergic responses to many medications
Johns Hopkins and University of Alberta researchers have identified a single protein as the root of painful and dangerous allergic reactions to a range of medications and other substances. If a new drug can be found that targets the problematic protein, they say, it could help smooth treatment for patients with conditions ranging from prostate cancer to diabetes to HIV.
As foreign and domestic health care workers in West Africa fight to contain the deadliest Ebola virus disease outbreak in history, a group of disaster response and modeling experts from Johns Hopkins say a potential pool of manpower to help care for patients with Ebola is being overlooked and should be tapped quickly: people who have survived and recovered from Ebola virus infection.
Clinical trial shows no beneficial effects on key measures of heart disease and diabetes risk
Good news for people who are already following a diet rich in fruits, vegetables and whole grains, and low in sweets: New research suggests these heart-healthy eaters don’t need to worry about choosing low glycemic index foods to lower the risk of diabetes and heart disease.
Study could lead to mitochondrial DNA blood tests to foretell risk
New research from The Johns Hopkins University suggests that the amount of mitochondrial DNA (mtDNA) found in peoples’ blood directly relates to how frail they are medically. This DNA may prove to be a useful predictor of overall risk of frailty and death from any cause 10 to 15 years before symptoms appear.
Small study shows so-called biofilms may increase cancer risk
Researchers from Johns Hopkins have found that dense mats of interacting bacteria, called biofilms, were present in the majority of cancers and polyps, particularly those on the right side of the colon. The presence of these bacterial bunches, they say, may represent an increased risk for colon cancer and could form the basis of new diagnostic tests.
Johns Hopkins/Jhpiego design aims to reduce infection risks for health care workers
An advanced protective suit for health care workers who treat Ebola patients, devised by a Johns Hopkins team, is one of the first five awardees in a federal funding contest aimed at quickly devising new tools to combat the deadly disease.

Johns Hopkins study is largest so far of gene expression in autism brains
While many different combinations of genetic traits can cause autism, brains affected by autism share a pattern of ramped-up immune responses, an analysis of data from autopsied human brains reveals. The study, a collaborative effort between Johns Hopkins and the University of Alabama at Birmingham, included data from 72 autism and control brains.
Many children who sustain so-called open bone fractures in the forearm or lower leg can, and do, heal safely without surgery, according to the results of a small study led by investigators at the Johns Hopkins Children’s Center.
Protein inhibitor makes cell susceptible to chemotherapy
Triple-negative breast cancer is as bad as it sounds. The cells that form these tumors lack three proteins that would make the cancer respond to powerful, customized treatments. Instead, doctors are left with treating these patients with traditional chemotherapy drugs that only show long-term effectiveness in 20 percent of women with triple-negative breast cancer. Now, researchers at The Johns Hopkins University have discovered a way that breast cancer cells are able to resist the effects of chemotherapy — and they have found a way to reverse that process.
Journalists are invited to hear from more than 20 Johns Hopkins-affiliated startups on Dec. 10 at an event entitled “A Healthcare Technology Day.” The showcase, which will run from 2 to 6 p.m. at The Johns Hopkins Hospital, will feature presentations by company management and offer opportunities for one-on-one interviews.
A step toward cracking the code of how brains work
Whether we’re paying attention to something we see can be discerned by monitoring the firings of specific groups of brain cells. Now, new work from Johns Hopkins shows that the same holds true for the sense of touch. The study brings researchers closer to understanding how animals’ thoughts and feelings affect their perception of external stimuli.

Experts urge caution in implementing pay-for-performance schemes tied to coordinating ‘transitional care’ of older adults
In what is believed to be the first interview-style qualitative study of its kind among health care providers in the trenches, a team led by a Johns Hopkins geriatrician has further documented barriers to better care of older adults as they are transferred from hospital to rehabilitation center to home, and too often back again.
Implications for autoimmune disease, vaccine design
Immunity is a thankless job. Though the army of cells known as the immune system continuously keeps us safe from a barrage of viruses, bacteria and even precancerous cells, we mainly notice it when something goes wrong: “Why did I get the flu this year even though I got vaccinated?” “Why does innocent pollen turn me into a red-eyed, sniffling mess?”
Fossils suggest ancestor of horses and rhinos originated on the Asian subcontinent while it was still an island
Working at the edge of a coal mine in India, a team of Johns Hopkins researchers and colleagues have filled in a major gap in science’s understanding of the evolution of a group of animals that includes horses and rhinos. That group likely originated on the subcontinent when it was still an island headed swiftly for collision with Asia, the researchers report Nov. 20 in the online journal Nature Communications.
Evidence of heart muscle damage seen even among symptom-free people
Using an ultrasensitive blood test to detect the presence of a protein that heralds heart muscle injury, researchers from Johns Hopkins and elsewhere have found that obese people without overt heart disease experience silent cardiac damage that fuels their risk for heart failure down the road.
A Blood Pressure Hormone Implicated in Psychosis; Nutrient Deficiency Linked to Brain Wasting in Huntington’s Disease; Autistic Mice Become Social with Drug Treatment
When the mouse and human genomes were catalogued more than 10 years ago, an international team of researchers set out to understand and compare the “mission control centers” found throughout the large stretches of DNA flanking the genes. Their long-awaited report suggests why studies in mice cannot always be reproduced in humans. Importantly, the scientists say, their work also sheds light on the function of DNA’s regulatory regions, which are often to blame for common chronic human diseases.
The following research findings were presented by Johns Hopkins cardiologists at the annual Scientific Sessions Meeting of the American Heart Association in Chicago.

Researchers capture images of a protein complex that keeps hearts beating
For years, a multidisciplinary team of Johns Hopkins researchers has tracked an elusive creature, a complex of proteins thought to be at fault in some cases of sudden cardiac death. As they report Nov. 5 in the online edition of Nature Communications, they have finally captured images of the complex. Those images reveal the connection between some genetic mutations and electrical abnormalities of the heart and provide a starting point for designing therapies.
Fear of loss, combined with positive or negative incentives, influences performance
Recent research from The Johns Hopkins University suggests that in high stakes situations, a person's performance depends on two factors: the framing of the incentive in terms of a loss or a gain, and their fear of loss.
The Ebola virus disease training modules for health care workers developed in collaboration between experts at Johns Hopkins Medicine and the Centers for Disease Control and Prevention (CDC) are now available.

Two new studies shed light on how cells sense and respond to chemical trails
Amoebas aren’t the only cells that crawl: Movement is crucial to development, wound healing and immune response in animals, not to mention cancer metastasis. In two new studies from Johns Hopkins, researchers answer long-standing questions about how complex cells sense the chemical trails that show them where to go — and the role of cells’ internal “skeleton” in responding to those cues.
Solution to 14-year mystery has implications for cancer therapies and drug delivery
Do blood vessels that feed tumors differ from other blood vessels? Fourteen years ago, experiments designed to answer that question led to the discovery of several genes that are more active in tumor-associated blood vessels than in normal blood vessels. New research now reveals the normal function of one of those genes and suggests it could be a good target for anticancer drug therapy.
Some people harboring the virus have subtle changes in cognitive function
Scientists from Johns Hopkins and the University of Nebraska have discovered an algae virus never before seen in the throats of healthy people that may subtly alter a range of cognitive functions including visual processing and spatial orientation in those who harbor it.
Johns Hopkins surgeons urge salvage of syringes, sutures, gauze, towels to improve care in developing countries
A Johns Hopkins research team reports that major hospitals across the U.S. collectively throw away at least $15 million a year in unused operating room surgical supplies that could be salvaged and used to ease critical shortages, improve surgical care and boost public health in developing countries.
Paying attention to the color of a newborn’s poop can mean the difference between life and death for babies with the rare liver disorder biliary atresia — the leading cause of liver transplants in children. The disease is almost universally heralded by white or clay-colored stools but is often diagnosed with woeful delays.
Find could be central to treating channel-related diseases such as cardiac arrhythmias, epilepsy and Parkinson’s
A common protein plays a different role than previously thought in the opening and closing of channels that let ions flow in and out of our cells, researchers at Johns Hopkins report. Those channels are critical to life, as having the right concentrations of sodium and calcium ions in cells enables healthy brain communication, heart contraction and many other processes. The new study reveals that a form of calmodulin long thought to be dormant actually opens these channels wide. The finding is likely to bring new insight into disorders caused by faulty control of these channels, such as cardiac arrhythmias, epilepsy and Parkinson’s disease, the researchers say.
Johns Hopkins Medicine has collaborated with the Centers for Disease Control and Prevention to design an interactive Web-based learning program that guides health care workers, nurses and physicians through government-approved protocols to aid clinicians as they provide care to patients who may be at risk of contracting the Ebola virus. The program trains health care providers in three critical areas: proper donning of personal protective equipment (PPE), the safe removal of gear and active monitoring skills. All three modules will be available for free on the CDC’s website in the coming weeks and later available to the millions of iOS users on iTunes U.
Combination therapy appears most effective
A multicenter study of 169 men and women with a common form of neck pain suggests that both spinal steroid injections and conservative treatment with physical therapy and painkillers work equally well to relieve pain in the short term. But over time, a combination of the two appears to offer the most relief.
New National Institutes of Health grant will fund training, research experience for undergraduates
Morgan State University has been awarded a $23.3 million grant, the National Institutes of Health (NIH) announced today.

Johns Hopkins and other cancer researchers report that a very short course of a chemotherapy drug, called cyclophosphamide, not only can prevent a life-threatening immune response in some bone marrow transplant recipients, but also can eliminate such patients’ need for the usual six months of immune suppression medicines commonly prescribed to prevent severe forms of this immune response. Patients receive cyclophosphamide for two days after their bone marrow transplant, in addition to two other chemotherapy drugs given before the transplant.
Added drug testing in mice shows role of preosteoclasts in maintaining bone health
Experiments in mice with a bone disorder similar to that in women after menopause show that a scientifically overlooked group of cells are likely crucial to the process of bone loss caused by the disorder, according to Johns Hopkins researchers. Their discovery, they say, not only raises the research profile of the cells, called preosteoclasts, but also explains the success and activity of an experimental osteoporosis drug with promising results in phase III clinical trials.
Johns Hopkins Children’s Center infectious disease specialist Sanjay Jain, M.D., has earned a Transformative Research Award from the National Institutes of Health (NIH) for his ongoing work to design a new noninvasive imaging method that can rapidly identify a wide variety of bacterial infections and monitor their response to treatment in real time.

In an analysis of genetic information among more than 87,000 men, a global team of scientists says it has found 23 new genetic variants — common differences in the genetic code — that increase a man’s risk for prostate cancer. The so-called meta-analysis, believed to be the largest of its kind, has revealed once hidden mutations among men in a broad array of ethnic groups comprising men of European, African, Japanese and Latino ancestry.
Two Johns Hopkins neuroscientists have discovered the “molecular brakes” that time the generation of important cells in the inner ear cochleas of mice. These “hair cells” translate sound waves into electrical signals that are carried to the brain and are interpreted as sounds. If the arrangement of the cells is disordered, hearing is impaired.
Using a pain clinic as a testing ground, researchers at Johns Hopkins have shown that a management process first popularized by Toyota in Japan can substantially reduce patient wait times and possibly improve the teaching of interns and residents.
Technique will likely have applications in forensic science and donor organ monitoring
Researchers at Johns Hopkins have identified a highly sensitive means of analyzing very tiny amounts of DNA. The discovery, they say, could increase the ability of forensic scientists to match genetic material in some criminal investigations. It could also prevent the need for a painful, invasive test given to transplant patients at risk of rejecting their donor organs and replace it with a blood test that reveals traces of donor DNA.

Experts say child’s relapse and two similar cases can pave way to future cure efforts
The news in July that HIV had returned in a Mississippi toddler after a two-year treatment-free remission dashed the hopes of clinicians, HIV researchers and the public at large tantalized by the possibility of a cure.
Animal study holds promise for treating diabetic ulcers and burns
A combination of two drugs already approved by the U.S. Food and Drug Administration for different applications reduces wound healing time by one-quarter and significantly decreases scar tissue in mice and rats, Johns Hopkins researchers report. If the findings, reported in the September issue of the Journal of Investigative Dermatology, hold true in future human studies, the dual treatment could speed skin healing in people with skin ulcers, extensive burns, surgical wounds and battlefield injuries.
Simple genetic test predicts dosage needed
Many African-Americans may not be getting effective doses of the HIV drug maraviroc, a new study from Johns Hopkins suggests. The initial dosing studies, completed before the drug was licensed in 2007, included mostly European-Americans, who generally lack a protein that is key to removing maraviroc from the body. The current study shows that people with maximum levels of the protein — including nearly half of African-Americans — end up with less maraviroc in their bodies compared to those who lack the protein even when given the same dose. A simple genetic test for the gene that makes the CYP3A5 protein could be used to determine what doses would achieve effective levels in individuals, the researchers say.
Chemical alterations to genes appear key to tumor development
Regardless of their stage or type, cancers appear to share a telltale signature of widespread changes to the so-called epigenome, according to a team of researchers. In a study of a broad variety of cancers, the investigators say they have found widespread and distinctive changes to chemical marks known as methyl groups attached to DNA. Those marks help govern whether genes are turned “on” or “off,” and ultimately how the cell behaves. Such reversible chemical marks on DNA are known as epigenetic, and together they make up the epigenome.
Johns Hopkins Medicine Dean and CEO Paul Rothman and Armstrong Institute for Patient Safety and Quality Director Peter Pronovost named to Modern Healthcare’s 100 Most Influential People in Healthcare list
Modern Healthcare, a leading industry publication, has named Johns Hopkins Medicine Dean and CEO Paul B. Rothman, M.D., and patient safety expert Peter J. Pronovost, M.D., Ph.D., to this year’s 100 Most Influential People in Healthcare list. The list recognizes individuals deemed by their peers and experts as leaders in the industry.
Discovery of changes to cell membranes has wide repercussions for drug developers
Researchers have discovered that three commonly used nonsteroidal anti-inflammatory drugs, or NSAIDs, alter the activity of enzymes within cell membranes. Their finding suggests that, if taken at higher-than-approved doses and/or for long periods of time, these prescription-level NSAIDs and other drugs that affect the membrane may produce wide-ranging and unwanted side effects.
Additional tool accelerates personalized medicine research
Johns Hopkins stem cell biologists have found a way to reprogram a patient’s skin cells into cells that mimic and display many biological features of a rare genetic disorder called familial dysautonomia. The process requires growing the skin cells in a bath of proteins and chemical additives while turning on a gene to produce neural crest cells, which give rise to several adult cell types. The researchers say their work substantially expedites the creation of neural crest cells from any patient with a neural crest-related disorder, a tool that lets physicians and scientists study each patient’s disorder at the cellular level.

Find likely to aid drug development
Researchers at Johns Hopkins have spotted a strong family trait in two distant relatives: The channels that permit entry of sodium and calcium ions into cells turn out to share similar means for regulating ion intake, they say. Both types of channels are critical to life. Having the right concentrations of sodium and calcium ions in cells enables healthy brain communication, heart contraction and many other processes. The new evidence is likely to aid development of drugs for channel-linked diseases ranging from epilepsy to heart ailments to muscle weakness.

Some cells in the retina pass off worn out parts to supporting cells for disposal
Biologists have long considered cells to function like self-cleaning ovens, chewing up and recycling their own worn out parts as needed. But a new study challenges that basic principle, showing that some nerve cells found in the eye pass off their old energy-producing factories to neighboring support cells to be “eaten.” The find, which may bear on the roots of glaucoma, also has implications for Parkinson’s, Alzheimer’s, amyotrophic lateral sclerosis (ALS) and other diseases that involve a buildup of “garbage” in brain cells.
Star-shaped brain cells “eavesdrop” on neurons, but only when primed
A new study from The Johns Hopkins University shows that the brain cells surrounding a mouse’s neurons do much more than fill space. According to the researchers, the cells, called astrocytes because of their star-shaped appearance, can monitor and respond to nearby neural activity, but only after being activated by the fight-or-flight chemical norepinephrine. Because astrocytes can alter the activity of neurons, the findings suggest that astrocytes may help control the brain’s ability to focus.

Despite earlier promise, latency-reversing strategy designed to mop up tiny reservoirs of HIV doesn’t work with current compounds
Scientists at Johns Hopkins report that compounds they hoped would “wake up” dormant reservoirs of HIV inside immune system T cells — a strategy designed to reverse latency and make the cells vulnerable to destruction — have failed to do so in laboratory tests of such white blood cells taken directly from patients infected with HIV.
“Overlay” of genetic and epigenetic maps described
Many diseases have their origins in either the genome or in reversible chemical changes to DNA known as the epigenome. Now, results of a new study from Johns Hopkins scientists show a connection between these two “maps.” The findings could help disease trackers find patterns in those overlays that could offer clues to the causes of and possible treatments for complex genetic conditions, including many cancers and metabolic disorders.
Magnetic pull of MRI shown in zebrafish and in people with common inner-ear disturbance
Expanding on earlier research, Johns Hopkins researchers report that people with balance disorders or dizziness traceable to an inner-ear disturbance show distinctive abnormal eye movements when the affected ear is exposed to the strong pull of an MRI’s magnetic field.
Insights at cellular level may explain patterns in developing embryos and how snails learn
Johns Hopkins biologists have discovered that when biological signals hit cells in rhythmic waves, the magnitude of the cells' response can depend on the number of signaling cycles — not their strength or duration. Because such so-called “oscillating signaling cycles” are common in many biological systems, the scientists expect their findings in single-celled organisms to help explain the molecular workings of phenomena such as tissue and organ formation and fundamental forms of learning.
Using a powerful data-crunching technique, Johns Hopkins researchers have sorted out how a protein keeps defective genetic material from gumming up the cellular works. The protein, Dom34, appears to “rescue” protein-making factories called ribosomes when they get stuck obeying defective genetic instructions.

A novel protein may explain how biological clocks regulate human sleep cycles
In a series of experiments sparked by fruit flies that couldn’t sleep, Johns Hopkins researchers say they have identified a mutant gene — dubbed “Wide Awake” — that sabotages how the biological clock sets the timing for sleep. The finding also led them to the protein made by a normal copy of the gene that promotes sleep early in the night and properly regulates sleep cycles.
Research has implications for preventing cancer metastasis
Studying epithelial cells, the cell type that most commonly turns cancerous, Johns Hopkins researchers have identified a protein that causes cells to release from their neighbors and migrate away from healthy mammary, or breast, tissue in mice. They also found that deletion of a cellular “Velcro protein” does not cause the single-celled migration expected. Their results, they say, help clarify the molecular changes required for cancer cells to metastasize.

Johns Hopkins researchers identify set of genes that can be turned back on and potentially allow for more effective treatment
Johns Hopkins researchers say they have identified a set of genes that appear to predict which tumors can evade detection by the body’s immune system, a step that may enable them to eventually target only the patients most likely to respond best to a new class of treatment.
An experimental drug aimed at restoring the immune system's ability to spot and attack cancer halted cancer progression or shrank tumors in patients with advanced melanoma, according to a multisite, early-phase clinical trial at Johns Hopkins Kimmel Cancer Center and 11 other institutions. All patients had experienced disease progression despite prior systemic therapies, and most had received two or more prior treatments.
In a study that began in a pair of infant siblings with a rare heart defect, Johns Hopkins researchers say they have identified a key molecular switch that regulates heart cell division and normally turns the process off around the time of birth. Their research, they report, could advance efforts to turn the process back on and regenerate heart tissue damaged by heart attacks or disease.

Researchers scanned brains while musicians “traded fours
The brains of jazz musicians engrossed in spontaneous, improvisational musical conversation showed robust activation of brain areas traditionally associated with spoken language and syntax, which are used to interpret the structure of phrases and sentences. But this musical conversation shut down brain areas linked to semantics - those that process the meaning of spoken language, according to results of a study by Johns Hopkins researchers.
The antidepressant drug citalopram, sold under the brand names Celexa and Cipramil and also available as a generic medication, significantly relieved agitation in a group of patients with Alzheimer's disease.

In normal development, all cells turn off genes they don’t need, often by attaching a chemical methyl group to the DNA, a process called methylation. Historically, scientists believed methyl groups could only stick to a particular DNA sequence: a cytosine followed by a guanine, called CpG. But in recent years, they have been found on other sequences, and so-called non-CpG methylation has been found in stem cells, and in neurons in the brain.
Investigators at Johns Hopkins report they have developed human induced-pluripotent stem cells (iPSCs) capable of repairing damaged retinal vascular tissue in mice. The stem cells, derived from human umbilical cord-blood and coaxed into an embryonic-like state, were grown without the conventional use of viruses, which can mutate genes and initiate cancers, according to the scientists. Their safer method of growing the cells has drawn increased support among scientists, they say, and paves the way for a stem cell bank of cord-blood derived iPSCs to advance regenerative medicine research.
Finding may aid development of less addictive medications
Setting the stage for possible advances in pain treatment, researchers at The Johns Hopkins University and the University of Maryland report they have pinpointed two molecules involved in perpetuating chronic pain in mice.

Details of an initial five-year affiliation outlined in the MOU are expected to be finalized within the next few months, officials of the institutions say.
Although the brain becomes smaller with age, the shrinkage seems to be fast-tracked in older adults with hearing loss, according to the results of a study by researchers from Johns Hopkins and the National Institute on Aging. The findings add to a growing list of health consequences associated with hearing loss, including increased risk of dementia, falls, hospitalizations, and diminished physical and mental health overall.
Using a simple study of eye movements, Johns Hopkins scientists report evidence that people who are less patient tend to move their eyes with greater speed. The findings, the researchers say, suggest that the weight people give to the passage of time may be a trait consistently used throughout their brains, affecting the speed with which they make movements, as well as the way they make certain decisions.
Study shows safe and simpler treatment for potentially deadly, liver-damaging disease
Efforts to cure hepatitis C, the liver-damaging infectious disease that has for years killed more Americans than HIV/AIDS, are about to get simpler and more effective, according to new research at Johns Hopkins and elsewhere.
