Equillium Announces Poster Presentation at the 50th Anniversary La Jolla Immunology Conference
LA JOLLA, Calif., Oct. 06, 2026 (GLOBE NEWSWIRE) -- Equillium, Inc. (Nasdaq: EQ), a biotechnology innovator developing novel therapies to treat severe autoimmune and inflammatory disorders, today announced that new preclinical data from its EQ504 program will be presented in a poster at the 50th Anniversary La Jolla Immunology Conference, taking place October 6-8, 2026 in La Jolla, California.
“These data provide additional insight into the multi-modal activity of EQ504, demonstrating coordinated effects across epithelial and immune compartments that preserve barrier integrity while resolving inflammation,” said Dr. Stephen Connelly, Chief Scientific Officer of Equillium. “We believe these complementary effects are particularly relevant to ulcerative colitis, where both reducing inflammation and improving mucosal healing are important to achieving meaningful outcomes for patients.”
Details of the poster presentations:
Title: AhR activation stabilizes inflammatory crosstalk and promotes barrier repair in an intestinal co-culture model
Poster Number: I-37
Lead Author: Rosa Quinn Closser
Presentation Type: Poster Session 1
Date: October 6, 2026
Time: 11:00am to 1:00pm PT
Presentation Summary: EQ504 demonstrated coordinated effects across epithelial and immune compartments in an intestinal co-culture model, preserving barrier integrity while suppressing inflammatory cytokine production. These findings further support the potential of EQ504 to address both barrier dysfunction and inflammation in ulcerative colitis.
Following the presentation, the poster will be available on the Presentations page located under the Technology section of equilliumbio.com.
About EQ504
EQ504 is an investigational potent and selective aryl hydrocarbon receptor (AhR) modulator with a multi-modal, non-immunosuppressive mechanism of action designed to be complementary to other inflammation and immunology agents. AhR is critical to barrier organ tissue physiology and immunology, maintaining barrier function and promoting tissue repair and regeneration, while regulating resident immune cells with anti-inflammatory responses. EQ504’s preclinical properties provide the potential for targeted, local delivery via enteric coating for the treatment of ulcerative colitis and other gastrointestinal diseases or inhaled formulations for the treatment of inflammatory lung diseases.
