Role of Regulated Cell Death Pathways in Snakebite Envenomation: Mechanisms, Crosstalk, and Therapeutic Opportunities

  Role of Regulated Cell Death Pathways in Snakebite Envenomation: Mechanisms, Crosstalk, and Therapeutic Opportunities Abstract Snakebite envenomation causes severe tissue damage, often resulting in permanent disability with long-term complications like amputations and organ dysfunction. Current antivenoms, which are antibody-based, have lower tissue penetrability and limited efficacy in minimizing the local effects, highlighting the need for adjunct therapies. Emerging evidence indicates that venom-induced pathology is not restricted to direct cytotoxicity and necrosis; rather, it also involves multiple interconnected Regulated Cell Death (RCD) pathways, but their mechanistic interplay and therapeutic implications remain poorly understood. This review examines how venom toxins induce a cellular stress response characterized by oxidative stress, membrane disruption, and calcium overload, leading to the activation of interconnected regulated cell death (RCD) pathways, including apo...
