In this episode, we dive into groundbreaking research that uncovers how aspirin, a household name for pain relief, could play a surprising role in fighting cancer metastasis. Join us as we explore how aspirin and related compounds boost T-cell immunity by targeting a newly discovered immunosuppressive pathway. We’ll break down the science behind platelet-derived thromboxane A2 (TXA2), the ARHGEF1 pathway, and how aspirin’s inhibition of cyclooxygenase 1 (COX-1) unleashes T-cells to combat metastasizing cancer cells. Backed by compelling mouse studies, this research reveals aspirin's anti-metastatic potential and opens the door to innovative immunotherapy strategies.
