背景信息

MAdCAM-1 (Mucosal Addressin Cell Adhesion Molecule 1) is a cell surface glycoprotein belonging to the immunoglobulin superfamily, primarily expressed on endothelial cells of mucosal tissues, gut-associated lymphoid tissue (GALT), and inflamed sites. It plays a critical role in lymphocyte homing by interacting with integrin α4β7 and L-selectin (CD62L) on leukocytes, facilitating immune cell recruitment to mucosal surfaces. This interaction is pivotal in maintaining gut immunity but also contributes to pathologies like inflammatory bowel disease (IBD), autoimmune disorders, and cancer metastasis.

MAdCAM-1-targeted antibodies are therapeutic agents designed to block this adhesion pathway, thereby reducing inflammatory cell infiltration. Monoclonal antibodies (e.g., vedolizumab, though primarily α4β7-targeted) and experimental anti-MAdCAM-1 agents (e.g., ontamalimab) inhibit leukocyte migration, offering localized immunosuppression with fewer systemic side effects. Research highlights their efficacy in IBD models, particularly ulcerative colitis, by dampening chronic inflammation. Additionally, MAdCAM-1 overexpression in certain cancers links it to tumor microenvironment modulation, suggesting potential oncological applications.

Current studies focus on optimizing antibody specificity, pharmacokinetics, and safety profiles. Challenges include balancing mucosal immune suppression with infection risks and addressing variable patient responses. MAdCAM-1 antibodies represent a promising niche in biologics, bridging mucosal immunology and targeted therapy.
