Cell Adhesion
Cell Adhesion — The process by which cells attach to surfaces or other cells through receptor-ligand interactions, studied using RGD-containing peptides and integrin-binding sequences.
What Is Cell Adhesion?
Cell adhesion is the binding of cells to other cells or to extracellular matrix components through specific receptor-ligand interactions. Integrins are the primary adhesion receptors, and the tripeptide motif RGD (Arg-Gly-Asp) is the most important integrin recognition sequence, making it one of the most widely studied peptide motifs in biomaterials and tissue engineering.
Peptide Applications
- RGD peptides: Grafted onto biomaterial surfaces to promote cell attachment. Linear and cyclic RGD variants target different integrin subtypes
- Cilengitide: Cyclic RGDfV pentapeptide that inhibits integrins alpha-v-beta-3/5. Studied as anti-angiogenic cancer therapy
- YIGSR: Laminin-derived peptide promoting neural cell adhesion
- Self-assembling scaffolds: RGD-functionalized peptide hydrogels for 3D cell culture and tissue regeneration
