Vascular collagen (None)

Vascular collagen refers to the structural proteins, primarily Type I, III, and IV collagen, that constitute the extracellular matrix of blood vessel walls. In a healthy vessel, collagen is sequestered within the subendothelial space, providing mechanical strength and elasticity to the vasculature (Source: PubMed, PMID: 25633596). However, upon vascular injury or atherosclerotic plaque rupture, exposed collagen becomes a potent stimulus for thrombus formation by binding to platelet receptors such as Glycoprotein VI (GPVI) and integrin alpha-2/beta-1 (Source: StatPearls, Collagen). This interaction triggers platelet adhesion, activation, and aggregation, making vascular collagen a critical target for lesion-directed antithrombotic therapies. Beyond hemostasis, excessive collagen deposition (fibrosis) and altered cross-linking contribute to arterial stiffness and hypertension (Source: NIH, Vascular Fibrosis). Therapeutic strategies include using fusion proteins like Revacept to coat exposed collagen and prevent thrombosis without significantly increasing systemic bleeding risks, as well as small molecules that inhibit collagen synthesis to treat vascular remodeling (Source: ClinicalTrials.gov, NCT01645306).
