Education and Training

Nevil Singh is a graduate of the Tata Institute of Fundamental Research (TIFR, Bombay, India) where his thesis work focused on vaccine-antigens against the malarial parasite, Plasmodium falciparum. He then joined Ron Schwartz’s group at the NIAID, NIH for a post-doctoral fellowship, examining T cell tolerance to self-proteins. Subsequently, as a Research Scientist at the NIAID, he studied the mechanisms controlling the responsiveness and frequency of helper T cells. He joined the faculty of UMDSOM in 2013.

Research Interests

The Nevil Lab is interested in understanding how T cells respond to pathogens, tumors and self-antigens. Projects in the lab examine how T cells discriminate between these different sources of antigen and modulate their responses accordingly. 

- Negative regulatory signaling pathways in T cells restrain self-reactive T cells from causing autoimmune pathology. Conversely, these pathways also limit the ability of tumor-specific T cells to robustly reject tumors. The lab has used molecular genetic approaches to identify new molecules involved in such pathways. The lab is characterising how these regulators function and how such pathways can be modified in vivo to supress or enhance T cell responses.

- The kind of response a T cell makes is tailored precisely to the pathogen (or tumor) affecting the host but also strongly adapted to the specific tissue that is affected. Projects in the lab examine how this dual information (pathogen type plus tissue niche) is conveyed to T cells. 

- It has been known for a long time that the nervous system and immune system interact often both in the steady state and during infections. The lab is examining the mechanisms by which specific neurotransmitters regulate T cell function.
