Multiple pro-inflammatory pathways

Multiple pro-inflammatory pathways refer to the integrated network of intracellular and extracellular signaling cascades that drive the body's response to injury, infection, or stress (Medzhitov, 2008, Nature). Key pathways within this category include the Nuclear Factor-kappa B (NF-κB) system, the Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway, and various Mitogen-Activated Protein Kinase (MAPK) cascades (Oeckinghaus & Ghosh, 2009, Cold Spring Harb Perspect Biol; Hu et al., 2021, Signal Transduct Target Ther). These pathways are activated by stimuli such as Toll-like receptor (TLR) ligands or pro-inflammatory cytokines, leading to the transcription of genes that promote inflammation and immune cell recruitment. While essential for host defense, chronic or dysregulated activation of these pathways is a primary driver of autoimmune diseases, chronic inflammatory conditions, and the tumor microenvironment in cancer (Arthur & Ley, 2013, Nat Rev Immunol). Therapeutic interventions often target specific components of these pathways, such as JAK inhibitors or TNF-alpha blockers, to reduce pathological inflammation. However, because these pathways are also critical for normal physiological processes, broad inhibition can lead to significant safety concerns, most notably an increased susceptibility to opportunistic infections.
