Adhesion receptors are a class of cell surface proteins that play a crucial role in cell-cell and cell-matrix interactions. They are involved in various biological processes, including cell adhesion, migration, differentiation, and signaling. Adhesion receptors can be categorized into several families based on their structure and function, such as integrins, cadherins, selectins, and immunoglobulin superfamily (IgSF) receptors.

Integrins are heterodimeric transmembrane proteins composed of an alpha and a beta subunit. They mediate cell-matrix and cell-cell interactions by binding to extracellular matrix proteins and other adhesion receptors. Integrins are involved in processes such as cell migration, proliferation, and survival, and their dysfunction has been linked to various diseases, including cancer and autoimmune disorders.

Cadherins are calcium-dependent adhesion molecules that mediate homophilic interactions between adjacent cells. They are essential for tissue morphogenesis, maintenance of tissue integrity, and cell-cell communication. Cadherins are involved in processes such as cell adhesion, migration, and differentiation, and their dysregulation has been implicated in diseases such as cancer and neurodegenerative disorders.

Selectins are a family of adhesion receptors that mediate the initial interaction between leukocytes and endothelial cells during inflammation. They are involved in processes such as leukocyte rolling, adhesion, and transmigration, and their dysfunction has been linked to inflammatory diseases.

IgSF receptors are a large family of adhesion receptors that include proteins such as CD2, CD4, and CD8. They mediate cell-cell interactions and are involved in processes such as immune cell activation, differentiation, and signaling. IgSF receptors are also involved in the pathogenesis of various diseases, including autoimmune disorders and cancer.

Adhesion receptors are regulated by various mechanisms, including ligand binding, post-translational modifications, and intracellular signaling. Their dysregulation has been implicated in numerous diseases, making them an important target for therapeutic interventions. Further research is needed to fully understand the role of adhesion receptors in health and disease and to develop targeted therapies for their dysregulation.
