http://triscience.com Cell adhesion is the term that refers to the binding of a cell to a specific surface, extracellular matrix, or another cell. The cell attaches itself to one of the aforementioned places by using cell adhesion molecules such as integrins, cadherins, and selectins. Proper cellular adhesion plays an important role in maintaining multicellular structure. Signal transduction is a possible result of cellular adhesion, because it can link the cytoplasm of binding cells. The process of cell adhesion occurs differently in different types of cells. The process typically involves adhesion molecules that are first hydrolyzed by a couple of extracellular enzymes, and because of this, the cellular adhesion process is directly related to protein adsorption. In eukaryotic protozoan organisms, the cells express multiple adhesion molecules to start the process. In human cells, the adhesion molecules are immunoglobulin superfamily members, integrins, cadherins, and selectins, and each of these plays a different role and recognizes different types of ligand. If the cell adhesion process is defective, the problem can usually be traced and attributed to depects in the expression of adhesion molecules. Cell junctions are the main ingredients that allow cells to adhere. There are four basic types of cell junctions: the anchoring junctions (these transmit stress through attaching to the cytoskeleton and usually of the cell-cell or cell-matrix variety). The occluding junctions (these seal the gaps between the cells to form an impermeable barrier around the binding cells), the channel forming junctions (these link the cytoplasm of the adjacent cells) and the signal relaying junction (these are the synapses in the nervous system). Cell to cell adhesions in anchoring junctions are often mediated by the cadherins, but cell to matrix adhesions are governed by integrins. Selective cell to cell adhesion, on the other hand, uses homophilic attachment and allows vertebrate cells to assemble into organized tsissues that will then form organs. This category contains information about cell binding or adhesion, which is a process that initiates “communication” between different cells. daily 1 2012-06-18T07:39:14Z http://triscience.com/Cells/Binding/sequestrin-a-cd36-recognition-protein-on-plasmodium-falciparum-malaria-infected-erythrocytes-identified-by-anti-idiotype-antibodies The Cd36 molecule expressed by human endothelial cells is a receptor for the adhesion of erythrocytes infected with the human malaria parasite Plasmodium falciparum.
