The Immunology Podcast

Dive into the intriguing world of immunology, where researchers unveil the role of micelles in drug delivery. Discover how helminth infections may influence susceptibility to SARS-CoV-2. Highlights include investigations on TLR7 and immune cell behavior in juvenile arthritis and newborns. The discussion also explores microbiome effects on immune signaling and groundbreaking cytokine therapies for cancer. Finally, learn about innovative techniques in targeted immunotherapy and the pivotal role of regulatory T cells in minimizing allograft rejection.

Dr. Anthony Fauci, a leading immunologist renowned for his COVID-19 response, shares insights on the pandemic's lessons. Dr. Doug Green, an authority on T cell activation, discusses critical dynamics of T cell behavior. The conversation dives into immune challenges posed by aging and obesity, along with innovative strategies for enhanced cancer vaccines. Listeners can expect to gain a deeper understanding of T cell function and the importance of genetics in immune responses. Exciting advancements in immunology are also unveiled!

In May 2023, we attended IMMUNOLOGY2023, the annual meeting of the American Association of Immunologists in Washington, DC, and recorded daily episodes discussing highlights of the previous 24 hours. Here is the second of five special episodes from the meeting. Brenda and Jason discuss sessions on peripheral neuroimmune interactions and tumor cellular therapy. Highlights include the President’s Address by Dr. Mark Davis and Dr. Barbara Rehermann’s presentation on wild mouse microbiota.
