Research

B lymphocytes are a type of blood cell that perform a very important task, to make antibodies that neutralize infectious agents. Our overarching goal is to identify specific aspects of B cell biology that can be targeted to develop new treatment strategies against B cell malignancies and autoimmunity. We focus on activation signals transmitted inside B cells that enable protective immunity, and checkpoints that are critical for preventing B cells from becoming pathogenic. 


Biography

Neetu Gupta, PhD, is Associate Staff in the Department of Inflammation and Immunity at the Cleveland Clinic, and Associate Professor of Molecular Medicine at the Cleveland Clinic Lerner College of Medicine of Case Western Reserve University. Dr. Gupta's basic research aims to identify mechanisms of B cell development, activation and antibody production, focusing specifically on the role of cytoskeletal proteins as regulators of membrane dynamics, signal transduction and subcellular compartmentalization. Dr. Gupta serves as the Director of the Cleveland Clinic Center of Excellence in Lymphoid Malignancies Research and seeks to foster teamwork, collaboration and cross-pollination of ideas among basic researchers and clinicians engaged in improving clinical care of lymphoma patients. Her research, spanning humoral immunity, autoimmunity, inflammation and cancer immunotherapy, has been published in high impact journals and funded by federal, foundation and institutional grants.

Dr. Gupta earned her graduate degree in Biochemistry from the Indian Institute of Science, Bangalore, and completed postdoctoral training in Immunology at the National Institutes of Health and University of California, San Francisco.

Adaptive Immunity - Cytoskeletal regulation of B cell development, activation and differentiation

We investigate molecular mechanisms of B cell activation that regulate humoral immunity and pathogenesis of B cell-mediated diseases. Dynamic remodeling of the B cell membrane and the actin cytoskeleton facilitates subcellular organization of key signaling proteins, enabling B cells to become activated in response to antigen, differentiate and generate pathogen-neutralizing antibodies. We employ high resolution live cell imaging, quantitative systems biology methods and genetic knockouts in mice to investigate the regulation of B cell function by cytoskeletal proteins such as Ezrin, a member of the Ezrin-Radixin-Moesin (ERM) family of membrane-cytoskeleton linker proteins, and unconventional myosin family proteins. Our studies are providing new insights into the molecular and cellular mechanisms that restrict B cell activation and differentiation, and thereby prevent autoimmunity.

Immuno-Oncology - Mechanisms and biomarkers of CAR T-cell function

As a member of the Center of Excellence in Lymphoid Malignancies Research at the Cleveland Clinic we are actively engaged in understanding the basis of resistance and relapse in aggressive B cell lymphomas and developing novel small molecule and cellular immunotherapies to improve clinical care of lymphoma patients. We are currently identifying the mechanisms and biomarkers of response and acute/chronic toxicities in lymphoma patients treated with CAR T-cells. We expect to apply the knowledge gained from our bed-to-bench investigations to bring improved and customized treatment strategies back to the patients.
