Sonoma Biotherapeutics Presents Data on Engineered Treg Cell Therapies Equipped with IL-2 Signaling at IMMUNOLOGY2023™

Sonoma Bio

Sonoma Biotherapeutics, Inc., a clinical-stage biotechnology company developing engineered regulatory T cell (Treg) therapies for autoimmune and inflammatory diseases, presented a poster at IMMUNOLOGY2023™, the American Association of Immunologists (AAI) Annual Meeting, titled: “Chimeric Cytokine Receptor Provides IL-2 Signaling for Engineered Regulatory T Cell Therapy.”

Interleukin-2 (IL-2), a cytokine signaling molecule in the immune system, is essential for Treg survival, expansion, phenotypic stability, and suppressive function. As Tregs do not produce IL-2, they are dependent on external sources for the molecule, limiting the persistence and durability of Treg cell therapies in tissues with no or limited IL-2 availability in the microenvironment. The study presented at IMMUNOLOGY2023 assessed the Company’s development of engineered Treg cells containing a chimeric cytokine receptor that provides an IL-2 signal, in order to address this challenge. Results of the study demonstrated the successful generation of Tregs with self-sufficient IL-2 signaling for clinical use in low IL-2 environments.
