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 final of five special episodes from the meeting. Brenda and Jason talk about sessions on mucosal immunity, emerging pathogens, and having a successful postdoctoral experience. Highlights include Dr. Isaac Chiu's talk on pain and mucus production in the gut, Dr. James Crowe's talk on monoclonal antibody discovery, and Dr. Amy Hartman's talk on Rift Valley fever virus.
