Innate immune signaling pathway

The innate immune signaling pathway refers to a collection of cellular signaling cascades triggered in response to pathogen-associated (PAMPs) or damage-associated molecular patterns (DAMPs), primarily through cell-surface or cytosolic pattern recognition receptors (such as TLRs, NLRs, RLRs, and cGAS–STING)[7][9][8][3][5]. These pathways activate kinases and transcription factors that drive the production of cytokines, chemokines, and other immune mediators, essential for the earliest phases of host defense, inflammation, initiation of adaptive immunity, and tissue homeostasis. Dysregulation or therapeutic manipulation of specific elements within these pathways underpins numerous interventions for cancer, infection, autoimmunity, and inflammatory disorders, but \"innate immune signaling pathway\" itself is not one molecule or defined protein[2][1][4]. Summary: \"Innate immune signaling pathway\" is not a druggable molecule or canonical target, but a collective term for various interconnected signaling mechanisms of innate immunity. For information on actionable therapeutic targets, focus should shift to individual pathway components like TLR4, cGAS, STING, TBK1, or JAK kinases[5][4][7][9].
