Research Lab Results
-
Alan Scott Lab
Research in the Alan Scott Lab involves several important areas of genomics. Our team collaborates on a study to investigate the exon and genome sequence variants that determine phenotype, with a specific focus on the genetic bases of cleft lip and palate. We are also involved in assessing and improving genomic technologies to provide next-generation sequencing and analysis of sequence data to the clinical environment. In addition, we have a longstanding interest in the problem of gene annotation and the evolutionary genomics of vertebrates, especially endangered species. -
Alyssa Parian Lab
The Alyssa Parian Lab works to identify early markers of dysplasia. We also study inflammatory bowel disease-associated cancers, conduct IBD clinical trials and examine IBD extraintestinal manifestations. -
Alzheimer's Disease Research Center
The goal of the Johns Hopkins Alzheimer's Disease Research Center (ADRC) is to accelerate the discovery of new treatments that are directed at the basic mechanisms of disease, and to hasten the time when effective treatments for AD and related disorders become a reality. We have a strong commitment to basic research regarding the underlying mechanisms of Alzheimer's Disease and related disorders, and how this may translate into effective treatment. We perform clinical research seeking to identify medications to delay or treat the symptoms of dementia. We also provided many educational programs for family members and professionals. -
Amit Pahwa Lab
The Amit Pahwa Lab conducts research on a variety of topics within internal medicine. Our most recent studies have explored misanalysis of urinalysis results, urinary fractional excretion indices in the evaluation of acute kidney injury and nocturnal enuresis as a risk factor for falls in older women. We also investigate cancer diagnostics and treatments. In this area, our recent research has included studying cutaneous shave biopsies for diagnosing primary colonic adenocarcinoma as well as growth inhibition and apoptosis in human brain tumor cell lines using selenium. -
Aliaksei Pustavoitau Lab
The Aliaksei Pustavoitau Lab conducts research on models and mechanisms of impaired consciousness in patients who have suffered acute brain injury. Examples of our work include a study on the mechanisms of neurologic failure in critical illness and another on the use of intensivist-driven ultrasound at the PICU bedside. We also have a longstanding interest in patient safety and quality of care in the ICU setting. -
Alain Labrique Lab
The Alain Labrique Lab conducts research on infectious diseases and public health. Our team studies the various factors that lead to maternal and neonatal mortality, particularly in underserved populations in South Asia, using the tools of infectious disease epidemiology, molecular biology and biostatistics. We work to better understand factors such as the interface of micronutrient deficiency and maternal/infant mortality and the prevention of nosocomial infections through mechanistic or nutritional interventions. We also have a longstanding interest in technologies that may enable early detection of disease.Principal Investigator

Ayse Gurses Lab
Work in the Ayse Gurses Lab examines several topics related to human factors, including methods for improving patient safety in the cardiac operating room, care coordination, transitions of care and compliance of providers with evidence-based guidelines. Our team also has an interest in research that explores the working conditions of nurses. We collaborate on studies related to the development of geriatrics health service delivery at all levels of the health system. -
J. Marie Hardwick Laboratory
Our research is focused on understanding the basic mechanisms of programmed cell death in disease pathogenesis. Billions of cells die per day in the human body. Like cell division and differentiation, cell death is also critical for normal development and maintenance of healthy tissues. Apoptosis and other forms of cell death are required for trimming excess, expired and damaged cells. Therefore, many genetically programmed cell suicide pathways have evolved to promote long-term survival of species from yeast to humans. Defective cell death programs cause disease states. Insufficient cell death underlies human cancer and autoimmune disease, while excessive cell death underlies human neurological disorders and aging. Of particular interest to our group are the mechanisms by which Bcl-2 family proteins and other factors regulate programmed cell death, particularly in the nervous system, in cancer and in virus infections. Interestingly, cell death regulators also regulate many other cellular processes prior to a death stimulus, including neuronal activity, mitochondrial dynamics and energetics. We study these unknown mechanisms. We have reported that many insults can trigger cells to activate a cellular death pathway (Nature, 361:739-742, 1993), that several viruses encode proteins to block attempted cell suicide (Proc. Natl. Acad. Sci. 94: 690-694, 1997), that cellular anti-death genes can alter the pathogenesis of virus infections (Nature Med. 5:832-835, 1999) and of genetic diseases (PNAS. 97:13312-7, 2000) reflective of many human disorders. We have shown that anti-apoptotic Bcl-2 family proteins can be converted into killer molecules (Science 278:1966-8, 1997), that Bcl-2 family proteins interact with regulators of caspases and regulators of cell cycle check point activation (Molecular Cell 6:31-40, 2000). In addition, Bcl-2 family proteins have normal physiological roles in regulating mitochondrial fission/fusion and mitochondrial energetics to facilitate neuronal activity in healthy brains.Principal Investigator

Janet Siliciano Lab
Research in the Janet Siliciano lab focuses on HIV. Areas of study include CD4-positive T lymphocytes, virus latency and highly active antiretrovirals. We recently explored the challenges of detecting HIV persistence during potentially curative interventions and the multifactorial nature of HIV-1 latency. -
Jean Kim Lab
The Jean Kim Laboratory performs translational research in the area of chronic rhinosinusitis, with a niche interest in the pathogenesis of hyperplastic nasal polyposis. Studies encompass clinical research to basic wet laboratory research in studying the underlying immune and autoimmune mediated mechanism of polyp growth and perpetuation of disease. Human cell and tissue culture models are used. Techniques in the laboratory include cell and tissue culture, real time PCR, immunoblot, ELISA, flow cytometry, immunohistochemistry, electron microscopy, gene array analysis, and other molecular approaches including genetic knockdowns. Approaches used in Dr. Kim’s clinical study designs include prospective and retrospective analysis of patient outcomes and clinical biomarkers, as wells controlled clinical trials.
