Local inflammation mediators

Local inflammation mediators are a diverse group of endogenous signaling molecules rapidly released at sites of tissue injury or infection to orchestrate an inflammatory response. Key classes include cytokines (such as TNF-α, IL-1β, IL-6), chemokines, eicosanoids (prostaglandins, leukotrienes), vasoactive amines (histamine, serotonin), peptides (such as bradykinin), and lipid mediators (such as platelet-activating factor). These mediators act on local blood vessels, immune cells, and tissue cells to induce vasodilation, vascular permeability, leukocyte recruitment, and activation. While essential for defense and tissue repair, dysregulated production or signaling by these mediators is central to autoimmune, infectious, and chronic inflammatory diseases. Due to the heterogeneity and pleiotropic effects of these mediators, "local inflammation mediators" refers to a functional class and not a unique druggable target or receptor.
