Molecular Characteristics of CD226

CD226 (DNAM-1) is a transmembrane glycoprotein belonging to the immunoglobulin superfamily, containing two Ig-like C2-type domains (Ig-like C2-type 1 and 2). A key coding variant rs763361 (Gly307Ser) is associated with autoimmune disease susceptibility and may influence receptor function. Understanding these molecular features is critical for designing selective agonists and interpreting clinical data.

Global Clinical Landscape & Future Outlook

The race for CD226-targeted therapeutics represents a strategic pivot in the TIGIT/CD226 immune checkpoint axis. As TIGIT inhibitors face clinical challenges, drug developers are increasingly exploring CD226 agonists as the activating counterpart—activating NK cell and T cell cytotoxicity through the DNAM-1 pathway. Major players are shifting from simple monoclonal agonists to next-generation bispecific formats (CD226 × CD3 or tumor antigens) and engineered CAR-NK constructs. The next wave of R&D focuses on conditional activation mechanisms to prevent systemic immune hyperactivation, while also addressing tumor-induced CD226 downregulation and internalization that can limit TIGIT-blocker efficacy.
