Proinflammatory cytokines, inflammatory enzymes, and reactive oxygen species (ROS)

This term refers to a heterogeneous group of biological molecules and chemical species that drive the inflammatory process and oxidative stress within the body. Proinflammatory cytokines, such as Tumor Necrosis Factor-alpha (TNF-alpha) and Interleukin-6 (IL-6), are signaling proteins secreted by immune cells to coordinate the inflammatory response (Source: Dinarello, C. A., Chest, 2000). Inflammatory enzymes like Cyclooxygenase-2 (COX-2) and Inducible Nitric Oxide Synthase (iNOS) facilitate the synthesis of prostaglandins and nitric oxide, which contribute to vasodilation and pain (Source: Ricciotti, E., & FitzGerald, G. A., Arterioscler Thromb Vasc Biol, 2011). Reactive Oxygen Species (ROS) are highly reactive oxygen-containing molecules that can damage DNA, proteins, and lipids, often exacerbating tissue injury in chronic diseases (Source: Mittal, M., et al., Antioxid Redox Signal, 2014). Because this entry encompasses multiple distinct classes of molecules, it is considered a broad biological category rather than a single therapeutic target. Drugs targeting these pathways include monoclonal antibodies that neutralize specific cytokines and small molecules that inhibit enzymatic activity to treat conditions like rheumatoid arthritis and inflammatory bowel disease (Source: StatPearls, Inflammation, 2023). The interplay between these factors is central to the progression of autoimmune disorders, cardiovascular disease, and neurodegeneration.
