Adrenergic control of circadian rhythms in CD8 T cells responding to influenza
PROJECT SUMMARY This application seeks to understand how circadian rhythms control T cell immunity to influenza infection through signals delivered by the sympathetic nervous system. Circadian rhythms are biological clocks that are entrained by light/dark cycles, and in mammals, those rhythms are synchronized systemically throughout the body via signals delivered by sympathetic and parasympathetic neurons. Our recent studies uncovered an unexpected role for the β2-adrenergic receptor in cytolytic responses of CD8+ T cells to a virus infection. Further, we found that selective deletion of the Adrb2 on CD8+ T cells profoundly disrupted circadian gene expression and oscillation frequencies as…
