Host inflammatory signaling pathways

Host inflammatory signaling pathways encompass a network of molecular mechanisms that allow cells to sense, respond to, and resolve inflammatory stimuli. Major pathways include NF-κB, MAPK, JAK-STAT, inflammasome complexes, and pattern recognition receptor signaling. These pathways coordinate the transcription of inflammatory mediators (cytokines, chemokines), cell survival, proliferation, differentiation, and programmed cell death, and are fundamental both to host defense and the pathology of inflammatory diseases. Therapeutic targeting of these pathways is central to the management of autoimmune, infectious, and inflammatory diseases, but specificity is essential, as broad targeting risks widespread immunosuppression and disruption of normal tissue function. If more precise drug targeting information is needed, individual pathway components (e.g., "NLRP3 inflammasome," "NF-κB p65 subunit," "Janus kinase 1") should be delineated rather than the umbrella term.
