SIGNAL-RELAYING JUNCTIONS- … Signal-relaying junctions, which can be synapses in the nervous system Alternatively, cell junctions can be categorised into two main types according to what interacts with the cell: cell–cell junctions, mainly mediated by cadherins, and cell–matrix junctions, mainly mediated by integrins. See more Cell adhesion is the process by which cells interact and attach to neighbouring cells through specialised molecules of the cell surface. This process can occur either through direct contact between cell surfaces such as See more Eukaryotes Plants cells adhere closely to each other and are connected through plasmodesmata, channels that cross the plant cell walls and … See more • Cell communication (biology) • Epithelium • Cytoskeleton • Differential adhesion hypothesis • Role of cell adhesions in neural development See more CAMs are classified into four major families: integrins, immunoglobulin (Ig) superfamily, cadherins, and selectins. Cadherins and IgSF are homophilic CAMs, as they directly bind to the same type of CAMs on another cell, while integrins and selectins are … See more Dysfunction of cell adhesion occurs during cancer metastasis.
