This episode provides an in-depth exploration of TLR (Toll-like Receptor) signaling pathways, focusing on two key adapter proteins: MyD88 and TRIF. The discussion breaks down how these pathways function in immune response, with MyD88 triggering inflammatory responses through NF-kB activation and cytokine production, while TRIF specializes in antiviral defense through interferon production. The conversation covers the molecular mechanisms, regulatory controls, and potential therapeutic applications, highlighting how dysregulation can lead to various diseases and how understanding these pathways could lead to new treatments.
