Cell Adhesion Molecules and Extracellular Matrix Components (CAMs and ECM)

Cell Adhesion Molecules (CAMs) and Extracellular Matrix (ECM) components represent a broad class of molecules essential for maintaining tissue architecture and mediating communication between cells and their environment. CAMs, such as integrins, cadherins, and selectins, are transmembrane proteins that facilitate cell-cell and cell-matrix interactions, playing a pivotal role in the leukocyte adhesion cascade and immune cell recruitment [1][4]. The ECM is a complex non-cellular network consisting of fibrous proteins like collagen and elastin, as well as glycosaminoglycans and proteoglycans, which provide structural support and biochemical cues that regulate cell survival and differentiation [2][5]. In disease states, dysregulation of these components can lead to pathological fibrosis, enhanced tumor metastasis through epithelial-mesenchymal transition, and chronic inflammatory conditions like inflammatory bowel disease [3]. Therapeutic interventions targeting this system include monoclonal antibodies that inhibit specific integrins to treat autoimmune disorders and enzymes designed to remodel the ECM in conditions like Dupuytren's contracture [4]. Given the diversity of this category, it is typically classified as a group of targets rather than a single therapeutic entity [1].
