Abstract:

Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by a T helper cells (th) 2-dominant immune response coupled with multifactorial immune dysregulation involving Th1, Th17, and Th22 pathways. Current therapeutic approaches confront significant clinical challenges, including suboptimal treatment responses in subsets of patients, safety risks associated with prolonged pharmacotherapy, and compromised patient adherence. Emerging evidence demonstrates that the OX40-OX40L signaling pathway orchestrates sustained immunoinflammatory responses through its regulatory role in antigen-presenting cell-T cell interactions. Monoclonal antibodies targeting this pathway effectively inhibit pathological immune activation, demonstrating dual clinical benefits of ameliorating cutaneous lesions and maintaining durable remission after treatment cessation. This review systematically elucidates the mechanistic involvement of the OX40-OX40L axis in AD pathogenesis and provides a comprehensive analysis of clinical trial advancements in anti-OX40/OX40L monoclonal antibody therapeutics.

Key words: anti-OX40 monoclonal antibody, anti-OX40L monoclonal antibody, atopic dermatitis, targeted therapy
