Immunol."],"abstract":"<jats:p>Necroptosis, a regulated form of necrotic cell death governed by the RIPK1-RIPK3-MLKL axis, is critically involved in host defense, inflammatory responses, and the pathogenesis of diverse diseases. Given the expanding complexity of its signaling networks and their context-dependent outcomes, a synthesized overview is essential. This review aims to: (1) delineate both canonical and non-canonical pathways of necroptosis induction; (2) elucidate the multifaceted regulation of its core executors (RIPK1, RIPK3, MLKL) by post-translational modifications and epigenetic mechanisms; and (3) analyze the intricate crosstalk between necroptosis and other cellular processes, including apoptosis, autophagy, and metabolic pathways. The subsequent analysis will evaluate how this sophisticated regulatory architecture poses challenges while unveiling novel therapeutic vulnerabilities. Finally, emerging translational strategies that target necroptosis in inflammatory, neurodegenerative, and ischemic conditions are discussed, and propose future directions to bridge mechanistic discoveries to clinical applications. Notably, beyond its pathogenic roles, necroptosis also functions as an essential host defense mechanism against viral infection and represents a promising therapeutic strategy for eliminating apoptosis-resistant cancer cells, highlighting its context-dependent dual nature.<\/jats:p>","DOI":"10.3389\/fimmu.2026.1824460","type":"journal-article","created":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T04:24:18Z","timestamp":1777523058000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Regulatory
