Dr. Alexander’s laboratory is focused on the role of adaptive immunity in the pathogenesis of hypertension and associated cardiovascular disease. Current projects are focused on the role of counter-regulatory immune mechanisms in hypertension, including determining the role of novel regulatory T cell subsets in the pathogenesis of hypertension and microvascular dysfunction. We perform cutting edge basic and translational research integrating vascular biology and immunology using a variety of approaches including molecular biology, physiology, highly dimensional single cell analysis, and human genetics. Our laboratory is also integrated with the translational research infrastructure in the Divisions of Clinical Pharmacology and Cardiovascular Medicine to enable novel studies on human tissues and cells. Ultimately, the goal of Alexander laboratory is to fundamentally advance our understanding of hypertension and related cardiovascular diseases to develop new therapies for the benefit of the tremendous number of individuals affected by these conditions.

Megan
Behringer, PhD
Assistant Professor of Biological Sciences
Assistant Professor of Pathology, Microbiology, and Immunology
Steven and Bunny Fayne Dean’s Faculty Fellow in Biological Sciences

Dr. Megan Behringer is a biologist in the Department of Biological Sciences and an Associate Director of the Vanderbilt Microbiome Initiative. Her laboratory employs experimental evolution combined with genomic analysis to study how environmental factors affect the creation of genetic variation (i.e. mutation) and influence how microbes adapt and diversify in novel complex environments. Among other environmental factors, these changes may be influenced by nutrient availability or limitation, spatial homogenization or structure, and the presence or absence of community members. Her laboratory also applies these concepts to pathogen/microbiome interactions, investigating eco-evolutionary feedbacks between disease-causing and disease-preventing organisms.

Janet Markle, PhD

Janet
Markle, PhD
Assistant Professor of Pathology, Microbiology, and Immunology

The Markle Lab is interested in understanding genetic determinants of immunity. Our studies are patient-based, and we focus on children with severe immune-mediated diseases. Our lab uses human whole exome and whole genome sequencing to discover monogenic (e.g. single gene) inborn errors of immunity in children with rare infectious, autoimmune, or auto-inflammatory diseases. We use a customized bioinformatic pipeline to sift through large genetic datasets to pinpoint candidate gene variants. Then, we study the impact of these variants on the expression and function of the encoded proteins. We aim to thoroughly characterize the functional impact of each variant at the molecular and cellular levels, and to this end we use both classical and cutting-edge techniques in molecular biology, protein biochemistry, in vitro cell culture approaches, and mass cytometry using patient leukocytes. Current projects include: inflammasome-activating mutations, mutations affecting cytokine receptors, novel candidate genes for intestinal inflammation, and characterizing the microbiota of patients with monogenic immune diseases. Our group uses both ‘dry-lab’ (computational) and wide variety of ‘wet-lab’ approaches and our interests lie at the crossroads of human genetics, human immunology, and host-microbe interactions.
