Cytokine Pathways Involved in Inflammation

Cytokine pathways involved in inflammation are complex signaling networks that coordinate the immune system's response to pathogens and tissue damage [1]. These pathways are initiated when pro-inflammatory cytokines, such as Tumor Necrosis Factor-alpha (TNF-α), Interleukin-1 (IL-1), and Interleukin-6 (IL-6), bind to their respective cell-surface receptors [2]. This binding triggers intracellular signaling cascades, most notably the Janus Kinase/Signal Transducer and Activator of Transcription (JAK/STAT) and Nuclear Factor-kappa B (NF-κB) pathways, which regulate the expression of genes involved in cell proliferation, survival, and the recruitment of additional immune cells [3]. While essential for host defense, the chronic or dysregulated activation of these pathways is a primary driver of various autoimmune and inflammatory diseases, including rheumatoid arthritis, psoriasis, and inflammatory bowel disease [4]. Therapeutic strategies often focus on neutralizing these cytokines using monoclonal antibodies or blocking their downstream signaling with small-molecule inhibitors [5]. These interventions have revolutionized the management of chronic inflammatory conditions but require careful monitoring due to the increased risk of immunosuppression and opportunistic infections [6].
