The Immunology Podcast

Guest: Dr. Shabaana Khader is a Professor and Chair of the Department of Microbiology at the University of Chicago. She discusses how the immune system responds to Mycobacterium tuberculosis, why tuberculosis remains one of the world’s deadliest infectious diseases, and the challenges of developing more effective vaccines. She highlights the role of lung-resident immunity, including Th17 responses and lymphoid structures, in controlling infection, and explains how advances in our understanding of host–pathogen interactions are guiding the design of next-generation TB vaccines.
