Inflammatory signaling pathways in skin cells

Inflammatory signaling pathways in skin cells represent a complex network of biochemical cascades that coordinate the cutaneous immune response to injury, infection, or environmental stressors. These pathways involve various cell types, including keratinocytes, fibroblasts, and resident immune cells, which utilize signaling nodes such as NF-κB, JAK-STAT, and MAPK to regulate the production of cytokines and chemokines (Source: NIH, StatPearls). Dysregulation of these pathways is a hallmark of chronic inflammatory skin diseases like psoriasis and atopic dermatitis, where overactive signaling leads to persistent tissue damage and impaired barrier function. Because this term describes a broad biological process rather than a single molecular entity, it is considered a therapeutic area or a collection of targets rather than a specific drug target itself. Pharmacological intervention typically focuses on specific components within these pathways, such as cytokine receptors or intracellular kinases, to restore immune homeostasis in the skin (Source: PubMed, Journal of Investigative Dermatology).
