APS Annual Meeting at Experimental Biology

Cell Signaling in the GI Tract and Liver

Featured Topic — Thursday, April 29, 2021 — 4:00 PM - 5:30 PM — Virtual Session, Room APS-9
GI and Liver Physiology Section — Chair: James E Casanova — Co-Chair: Rachel R Stine

This FT will be assembled based on an overview of abstracts submitted to the section, with the goal of forming a cohesive topic based on trends in submissions. Within the topical pool chosen, preference will be given to high-scoring abstracts from trainees and new speakers.

This session will have 6 15 minute (including q&a) presentations.
