The Karandikar lab aims to fully understand the complex cellular interplay governing the immune-mediated demyelinating disease multiple sclerosis (MS).  I study the regulatory potential of CD8 T cells that recognize central nervous system peptides, and am interested in the regulatory program they exert over time in vivo, as well the targets of their immunosuppressive mechanisms. We believe these lines of investigation hold implications for potential immunotherapies for MS patients.
