Thrombospondin is a multifunctional family of secreted glycoproteins, best known for their central role in mediating cell-to-cell and cell-to-matrix interactions within the extracellular matrix. The most studied member, thrombospondin-1 (TSP-1), is a matricellular protein that regulates diverse biological processes, including cell adhesion, migration, proliferation, apoptosis, and angiogenesis. TSP-1 is a key modulator of platelet aggregation and is released from platelet α-granules upon activation, where it interacts with fibrinogen and other receptors to influence coagulation and platelet function. Beyond hemostasis, TSP-1 exerts potent antiangiogenic effects by inhibiting endothelial cell migration and proliferation, and by activating transforming growth factor-beta (TGF-β), thus contributing to tissue remodeling and fibrosis.
Dysregulation of thrombospondin expression is implicated in several diseases. Elevated TSP-1 levels are associated with renal disease, where it promotes fibrosis and contributes to the progression of chronic kidney disease. It also plays a role in cardiovascular diseases, obesity, diabetes, and cancer, influencing immune responses, tumor growth, and metastasis. Clinically, thrombospondin is being explored as a biomarker for platelet activation, renal dysfunction, and certain cancers, such as pancreatic and cholangiocarcinoma, with potential diagnostic and prognostic applications. Its diverse functions and disease associations make thrombospondin a promising target for therapeutic intervention and biomarker development.
