Protein Signaling Cascades in Healing: How Cellular Pathways Coordinate Tissue Repair
Healing is not directed by a single molecule or pathway. It occurs through coordinated protein signaling cascades — interconnected biochemical pathways that regulate inflammation, matrix remodeling, and structural adaptation. When musculoskeletal tissue experiences injury or repetitive stress, proteins released by immune and structural cells bind to receptors and activate intracellular cascades. These cascades influence gene […]
