The Interface of Immune and Metabolic responses in Tuberculosis & Vitiligo

Group Members

Sachin Sharma, Anusha Krishnan, Farina Sultan, KriteeMehdiratta, Jyotsna Singh

Summary of Research

The thematic focus of our laboratory is to elucidate complex interplay between metabolic reprogramming and immunity in the context a pathogenic disease Tuberculosis and autoimmune skin disorder Vitiligo. Our endeavor is to define how metabolic imbalance drives disease pathogenesis and thereby develop novel therapeutic strategies that will tackle the underlying causes, rather than just the symptoms.
