Scientific Interest(s):

Dr. David Brooks’ laboratory is focused on understanding the mechanisms of viral pathogenesis and immunity that lead to effective virus clearance versus viral persistence. In particular, they are interested in the interplay between the myriad of signals and factors that program T-cell immunity and how they culminate in distinct functional outcomes.

Current projects in the laboratory include identifying the regulatory factors that program productive versus abortive T-cell responses, defining the factors that sustain T-cell immunity during periods of viral persistence and imaging immune cells and the immunosuppressive interactions that lead to viral persistence in vivo. Brooks’ laboratory is additionally interested in molecularly defining CD4 T-cell help and exploring the precise mechanisms of CD4 T-cell help that program functional memory T-cell differentiation following an acute infection and that sustain antiviral T-cell activity to control persistent viral infection. Ultimately, Brooks’ hope is that the elucidation of these mechanisms will aid in the development of novel targeted-vaccine strategies that enhance immunity, prevent infection and therapeutically correct immune dysfunction to control persistent viral infections.
