On June 18, ICIS hosted the first-ever IL-9-focused symposium at the Federation of Clinical Immunology Societies (FOCIS) annual meeting. Devotees of all things IL-9 gathered in San Francisco to hear about “IL-9: from birth to breath.”
The symposium was organized by IL-9 guru Mark Kaplan and newcomer (and Signals+ Co-Editor in Chief) Daniella Schwartz. The talks did in fact start with “birth”: Nardhy Gomez-Lopez presented exciting data implicating IL-9 as a major driver of preterm labor, a major health issues that affects over 10% of pregnancies. Matthew Olson discussed the cooperative effects of IL-1β and IL-2 in promoting Th9 differentiation, while Paula Licona-Limón described a novel Th9 lineage-specific role for PKA/PKIB signaling. Daniella Schwartz presented data on the role of IL-9 epigenetics and signaling in autoimmune diseases, while Lionel Apetoh described his seminal work establishing the antitumor roles of IL-9-producing T cells. Finally, ending at “breath”, Josalyn Cho presented her recent findings implicating allergen-induced IL-9 as a major driver of the shift from non-asthmatic allergy to allergic asthma, through the profiling of human airway-resident Th2 cells.
Scheduled towards the end of the member society symposia and immediately before the keynote address, the ICIS/FOCIS mini-symposium was very well-attended. Attendees were engaged, and speakers received a broad range of questions ranging from basic mechanisms to clinical implications. After the meeting speakers traded thoughts on IL-9 over dinner at The Stinking Rose while Mark and Daniella distributed IL-9 swag. While Th9 cells may sometimes be seen as the “black sheep” of T helper subsets – somewhere between a stable subset and a transient state – IL-9 is enjoying a renaissance as its functions in health and disease becomes more apparent. While this may have been the first gathering of IL-9 devotees, the organizers sincerely hope that our black sheep will finally be admired for her beauty, and they are grateful to the ICIS for making the IL-9 symposium a reality.
