Extracellular matrix components and hyaluronan-binding cell surface receptors

Extracellular matrix (ECM) components and hyaluronan-binding cell surface receptors represent a broad class of molecules essential for maintaining tissue structural integrity and regulating cellular behavior (Source: NIH). The ECM is composed of various fibrous proteins such as collagen and laminin, along with glycosaminoglycans like hyaluronan (HA), which act as ligands for specific receptors including CD44, RHAMM (HMMR), and LYVE-1 (Source: UniProt). These interactions trigger intracellular signaling pathways that govern cell adhesion, migration, and proliferation, making them critical in both normal physiology and disease states (Source: PubMed, PMID: 30331156). In oncology, the overproduction of HA and the upregulation of CD44 are frequently associated with tumor progression, chemoresistance, and metastasis (Source: Wikipedia). Therapeutic strategies targeting this axis include the administration of hyaluronidases to degrade the ECM for enhanced drug penetration and the development of monoclonal antibodies to block receptor-ligand interactions (Source: DrugBank). However, because these components are ubiquitous throughout the body, therapeutic interventions must be carefully managed to avoid adverse effects on healthy tissue architecture and wound healing processes (Source: StatPearls).

The primary mechanisms include the enzymatic hydrolysis of hyaluronan by hyaluronidases to reduce tissue viscosity and interstitial fluid pressure, thereby improving drug delivery, and the antagonism of cell surface receptors like CD44 to disrupt pro-tumorigenic signaling, cell adhesion, and migratory pathways (Source: DrugBank; PubMed, PMID: 24388214).
