IMMUNOLOGY2026™-Thetis cell regulation of intestinal tolerance

Video Transcription

Video Summary

AAI President Steve Jamieson welcomed attendees to Immunology 2025 in Honolulu, emphasizing that AAI supports the immunology community year-round through science, policy, and public engagement. He noted recent pressures on scientists and highlighted AAI advocacy efforts, including its first congressional briefing on long COVID, strengthened media outreach, and sustainability initiatives at the meeting. He also announced an upcoming computational immunology course to train researchers in bioinformatics approaches such as single-cell RNA-seq and immune repertoire analysis.<br /><br />Jamieson presented the 2025 AAI Lifetime Achievement Award to Leslie J. Berg, recognizing her landmark discoveries in T cell signaling (including work on JAK3 and ITK), leadership as chair at the University of Colorado, and extensive service to AAI, NIH, and scientific publishing. Berg thanked colleagues, trainees, and AAI staff. AAI then inducted 19 Distinguished Fellows, honoring leading immunologists for scientific contributions and service.<br /><br />AAI CEO Loretta Doan outlined expanded advocacy: 47 congressional meetings, a new grassroots letter-writing program generating 2,000+ letters, and development of member-informed position statements. She described new media and public-awareness initiatives to counter misinformation, a “News and Views” hub, and a forthcoming biweekly newsletter. She also noted governance review efforts and a new publishing partnership with Oxford University Press.<br /><br />John Hardy introduced Jamieson’s presidential address, summarizing his influential career in CD8 T cell biology. Jamieson’s talk reviewed his lab’s work on how self–peptide-MHC and cytokines shape naive T cell maintenance and “virtual memory” formation, and how trafficking programs regulated by KLF2/S1PR1 control T cell egress, circulation, and tissue residency.
