Discover the fascinating world of regulatory T cells, which recently garnered a Nobel Prize for their role in preventing autoimmunity. The hosts dive into the history of suppressor T cells, the pivotal findings of FOXP3 mutations in mice, and how these discoveries relate to human diseases like IPEX syndrome. They also discuss the challenges of identifying true regulatory T cells and the mechanisms through which they exert their influence. Tune in for a compelling exploration of immunology's breakthroughs and ongoing mysteries!

In this engaging discussion, Professor Susan Schwab from NYU Grossman School of Medicine shares her journey from environmental advocacy to pioneering research in immunology. She dives into how sphingosine-1-phosphate (S1P) directs T cell movement, deciding when they should leave tissues. Susan also reveals intriguing findings about S1P's role in leukemia migration and highlights the use of optogenetic tools to track T cell behavior. Plus, she shares a hilarious travel tale involving flying cockroaches!
