Biography

Sushmita Sinha is an Assistant Professor at the Biology Department at Texas Women's University. She completed post-doctoral training at the Oregon health and Science University and at the UT Southwestern Medical Center. After working at the University of Iowa, Dr. Sinha joined the faculty at TWU. The major goal of her lab is to understand the regulation of effector responses from human T-cells with the focus of finding novel therapeutic targets for autoimmunity.

Current Projects

Despite extensive research, the etiology and underlying immune mechanisms responsible for precipitating autoimmunity remain poorly understood. Genetic risk variants identified by GWAS studies provide novel clues regarding pathogenic mechanisms in autoimmune diseases, however, in most cases the biological consequence of the risk variants and the mechanisms by which they potentiate autoimmunity remains unknown. We focus on Signal Regulatory Protein gamma (SIRP) due to 1) its putative association with Type 1 diabetes (T1D) by multiple GWAS studies 2) our novel preliminary finding that two T-cell mediated autoimmune diseases relapsing remitting multiple sclerosis (RRMS) and T1D (Clin Immunol 2019; PLOS One 2020) showed a significantly greater preponderance of T-cells with abnormally reduced SIRP. SIRP is expressed by both CD4 and CD8 T-cells in humans, however, the role of SIRP and its potential contribution to autoimmunity remains unknown. My research program is focused on two interconnected themes: 1) to understand the role of SIRP in regulating effector T-cell responses in healthy immune system; and 2) to identify the mechanisms by which abnormal reduction in SIRP expression on T-cells predisposes/ potentiates autoimmunity.
