Immune cytokine signaling (None)

Immune cytokine signaling is a fundamental biological process involving the production and reception of small proteins called cytokines that coordinate the immune system's response to infection, injury, and inflammation (Source: NIH). These molecules, which include interleukins, interferons, and tumor necrosis factors, bind to specific high-affinity receptors on target cells to trigger intracellular signaling cascades, most notably the Janus kinase-Signal Transducer and Activator of Transcription (JAK-STAT) pathway (Source: StatPearls). This signaling regulates critical cellular activities such as proliferation, differentiation, and activation of immune cells like T cells, B cells, and macrophages (Source: PubMed). In many pathological states, such as rheumatoid arthritis, psoriasis, and inflammatory bowel disease, cytokine signaling becomes dysregulated, leading to chronic inflammation and tissue damage (Source: Nature Reviews Drug Discovery). Therapeutic strategies to modulate this pathway include the use of biologic agents to sequester cytokines or block their receptors, as well as small-molecule inhibitors that target the intracellular kinases responsible for signal transduction (Source: Wikipedia).
