Dr. Henrique Borges da Silva is an Assistant Professor at the Mayo Clinic in Arizona. His main research focus is determining how extracellular nucleotides affect transcriptional, metabolic, and functional mechanisms of CD8+ T cells in response to viral infections and cancer. He talks about where extracellular ATP comes from, and how there could be a link between ATP and ADP immunological signaling and the powers of caffeine.
