The Antoine Azar Lab conducts research on topics related to primary immunodeficiency diseases, allergies and lung disease. Specifically, we explore the role of primary immunodeficiency in certain difficult-to-treat chronic lung diseases, such as COPD, emphysema and asthma.
Research in the Bradley Undem Lab centers around the hypothesis that the peripheral nervous system is directly involved in the processes of inflammation. This hypothesis is being studied primarily in the central airways and sympathetic ganglia. We are addressing this in a multidisciplinary fashion, using pharmacological, electrophysiological, biochemical and anatomical methodologies.
Research in the Brendan J. Canning Lab is focused on mechanistic studies of the cough reflex. Through our work, we identified the afferent nerves that play an essential role in regulating cough. We have also been characterizing the CNS pathways regulating the cough reflex and interactions amongst various afferent nerve subtypes in regulating cough. We have identified key sites of integration of airway afferent nerve input and mechanisms by which afferent nerve subtypes act synergistically to regulate cough. Our experimental approaches include electrophysiological recordings, CNS microinjection techniques, in vivo preparations for monitoring cough and reflex bronchospasm, neuronal tracing and immunohistochemistry.
Research in the Donald MacGlashan Laboratory aims to understand the regulation of secretion from human basophils and mast cells—two cells thought to play key roles in allergic reactions and other diseases. The hallmark reaction in these cells is degranulation through cell-bound IgE. Our interests lie in the signaling mechanisms that control this dramatic cell response and the factors that regulate the degree of the reaction.
The Jody Tversky Lab studies dendritic cells in allergy and immunotherapy; cluster immunotherapy clinical observations and immune tolerance; and clinical diagnostic sensitivity of 10 allergy skin prick devices.
The John Schroeder Lab focuses on understanding the role human basophils and mast cells play in allergic reactions, as it relates not only to their secretion of potent inflammatory mediators (e.g., histamine and leukotriene C4) but also to their production of pro-inflammatory cytokines. We have long utilized human cells rather than cell lines in order to address the parameters, signal transduction and pharmacological aspects underlying clinically relevant basophil and mast cell responses. As a result, the lab has established protocols for rapidly isolating large numbers of basophils at high purity from human blood and for growing culture-derived mast cells/basophils from human progenitor cells. A variety of assays and techniques are also in place for concurrently detecting cytokines and mediators following a wide range of stimuli. These have facilitated the in vitro testing of numerous anti-allergic drugs for inhibitory activity on basophil and mast cell activation. The lab also studie...s counter-regulation between the IgE and innate immune receptors on human immature dendritic cell subtypes. view more
The mission of the Johns Hopkins University Dermatology, Allergy and Clinical Immunology (DACI) Reference Laboratory is to provide comprehensive, high-quality diagnostic allergy and immunology testing to patients throughout North America with asthma, allergy and immunologic disorders.

Current research includes implementation of high-throughput technologies in the fields of genome-wide association studies (GWAS), massively parallel sequencing, gene expression analysis, epigenetic mapping and integrative genomics in ongoing research of complex lung diseases and allergic diseases including asthma, atopic dermatitis (AD), pulmonary arterial hypertension, COPD, sepsis and acute lung injury/ARDS; and epigenetic contributions to pulmonary arterial hypertension associated with systemic sclerosis.
Research in the Marian Kollarik Lab focuses on specific phenotype of visceral sensory nerves, termed nociceptive, that detect stimuli associated with impeding or actual tissue damage. Nociceptors trigger defensive reflexes and/or sensations of discomfort and pain. For example, nociceptors initiate cough, sneezing, nasal itching, bronchoconstriction and mucus hypersecretion in the respiratory system, and pain and hypersecretion in the gastrointestinal system. An increase in nociceptive activity contributes significantly to the pathogenesis of respiratory and gastrointestinal diseases and their symptoms. Importantly, inflammation profoundly alters properties of nociceptive nerves per se, leading in general to exaggerated nociceptive responsiveness. Our research centers on this aspect of visceral nociception in allergic and non-allergic inflammation. We carry out electrophysiological and anatomical studies in isolated tissues and reflex studies in animal models.
The Peisong Gao Lab’s major focus is to understand the immunological and genetic regulation of allergic diseases. We have been involved in the identification of the genetic basis for atopic dermatitis and eczema herpeticum (ADEH) as part of the NIH Atopic Dermatitis and Vaccinia Network-Clinical Studies Consortium. Major projects in the Gao Lab include immunogenetic analysis of human response to allergen, identification of candidate genes for specific immune responsiveness to cockroach allergen, and epigenetics of food allergy (FA).

The Robert Shochet Lab focuses on medical education research, including the impact of learning communities on students' perceptions of the learning environment in medical school.
Research in the Anderson laboratory focuses on cellular signaling and ionic mechanisms that cause heart failure, arrhythmias and sudden cardiac death, major public health problems worldwide. Primary focus is on the multifunctional Ca2+ and calmodulin...-dependent protein kinase II (CaMKII). The laboratory identified CaMKII as an important pro-arrhythmic and pro-cardiomyopathic signal, and its studies have provided proof of concept evidence motivating active efforts in biotech and the pharmaceutical industry to develop therapeutic CaMKII inhibitory drugs to treat heart failure and arrhythmias.
Under physiological conditions, CaMKII is important for excitation-contraction coupling and fight or flight increases in heart rate. However, myocardial CaMKII is excessively activated during disease conditions where it contributes to loss of intracellular Ca2+ homeostasis, membrane hyperexcitability, premature cell death, and hypertrophic and inflammatory transcription. These downstream targets appear to contribute coordinately and decisively to heart failure and arrhythmias. Recently, researchers developed evidence that CaMKII also participates in asthma.
Efforts at the laboratory, funded by grants from the National Institutes of Health, are highly collaborative and involve undergraduate assistants, graduate students, postdoctoral fellows and faculty. Key areas of focus are:
• Ion channel biology and arrhythmias
• Cardiac pacemaker physiology and disease
• Molecular physiology of CaMKII
• Myocardial and mitochondrial metabolism
• CaMKII and reactive oxygen species in asthma

He studies the identification and manipulation of age- and mutation-dependent modifiers of cardiac function, hierarchical modeling and imaging of contractile machinery, integrative analysis of striated muscle performance and myopathic processes. view more
The Cardiology Bioengineering Laboratory, located in the Johns Hopkins Hospital, focuses on the applications of advanced imaging techniques for arrhythmia management. The primary limitation of current fluoroscopy-guided techniques for ablation of car...diac arrhythmia is the inability to visualize soft tissues and 3-dimensional anatomic relationships.
Implementation of alternative advanced modalities has the potential to improve complex ablation procedures by guiding catheter placement, visualizing abnormal scar tissue, reducing procedural time devoted to mapping, and eliminating patient and operator exposure to radiation.
Active projects include
• Physiological differences between isolated hearts in ventricular fibrillation and pulseless electrical activity
• Successful ablation sites in ischemic ventricular tachycardia in a porcine model and the correlation to magnetic resonance imaging (MRI)
• MRI-guided radiofrequency ablation of canine atrial fibrillation, and diagnosis and intervention for arrhythmias
• Physiological and metabolic effects of interruptions in chest compressions during cardiopulmonary resuscitation

The Foster Lab uses the tools of protein biochemistry and proteomics to tackle fundamental problems in the fields of cardiac preconditioning and heart failure. Protein networks are perturbed in heart disease in a manner that correlates only weakly wi...th changes in mRNA transcripts. Moreover, proteomic techniques afford the systematic assessment of post-translational modifications that regulate the activity of proteins responsible for every aspect of heart function from electrical excitation to contraction and metabolism. Understanding the status of protein networks in the diseased state is, therefore, key to discovering new therapies.

The O’Rourke Lab uses an integrated approach to study the biophysics and physiology of cardiac cells in normal and diseased states.
Research in our lab has incorporated mitochondrial energetics, Ca2+ dynamics, and electrophysiology to provide tool...s for studying how defective function of one component of the cell can lead to catastrophic effects on whole cell and whole organ function. By understanding the links between Ca2+, electrical excitability and energy production, we hope to understand the cellular basis of cardiac arrhythmias, ischemia-reperfusion injury, and sudden death.
We use state-of-the-art techniques, including single-channel and whole-cell patch clamp, microfluorimetry, conventional and two-photon fluorescence imaging, and molecular biology to study the structure and function of single proteins to the intact muscle. Experimental results are compared with simulations of computational models in order to understand the findings in the context of the system as a whole.
Ongoing studies in our lab are focused on identifying the specific molecular targets modified by oxidative or ischemic stress and how they affect mitochondrial and whole heart function.
The motivation for all of the work is to understand
• how the molecular details of the heart cell work together to maintain function and
• how the synchronization of the parts can go wrong
Rational strategies can then be devised to correct dysfunction during the progression of disease through a comprehensive understanding of basic mechanisms.

The Post Lab is involved in the Multi-Ethnic Study of Atherosclerosis (MESA), a collaborative study of the characteristics of subclinical cardiovascular disease (that is, disease detected non-invasively before it has produced clinical signs and sympt...oms) and the risk factors that predict progression to clinically overt cardiovascular disease or progression of the subclinical disease.
As MESA researchers, we study a diverse, population-based sample of 6,814 asymptomatic men and women aged 45-84. Approximately 38 percent of the recruited participants are white, 28 percent African-American, 22 percent Hispanic, and 12 percent Asian, predominantly of Chinese descent.
Participants were recruited from six field centers across the United States, including Johns Hopkins University. Each participant received an extensive physical exam to determine a number of conditions, including coronary calcification, ventricular mass and function, flow-mediated endothelial vasodilation, standard coronary risk factors, sociodemographic factors, lifestyle factors, and psychosocial factors.
Selected repetition of subclinical disease measures and risk factors at follow-up visits have allowed study of the progression of disease. Participants are being followed for identification and characterization of cardiovascular disease events, including acute myocardial infarction and other forms of coronary heart disease (CHD), stroke, and congestive heart failure; for cardiovascular disease interventions; and for mortality.
