What is cellular adhesion?

cell adhesion occurs when one cell binds to another surface, such as another cell or some other inanimate surface. To achieve this binding, the cell molecules (CAM) of the cell adhesive molecules (CAM) are used as intermediates that hold the cell to another surface. CAM are proteins that can generally be found on the surface of the membrane cells. Many different types of cells in plants, animals and other organisms must be tied for different purposes such as nutrient transmission and structural support. Cells often bind to an extracellular matrix that exist outside the organism cells and that provide structural support while providing many other important functions.

There are several different types of cellular proteins, but most work on the general purpose of tying the cell to another surface. These proteins generally have three primary aspects. The intercellular domain is able to interact and bind to the cytoskeleton of the cells, the protein structure in Cecytoplasm LL, which maintains a cellular structure and shape. TransmThe embedge domain is able to interact and bind to the outer membrane of the cells. The extracellular domain is bound to objects outside the cell, such as other adhesive cell proteins or extracellular matrix.

Extracellular matrix is ​​commonly involved in cellular adhesion because it provides structure and organization to large groups of cells and must be physically associated with them to do so. Extracellular matrix consists of tissue, which is commonly referred to as connective tissue in animals. The structure is the primary purpose of the extracellular matrix; They hold the cells together when cells bind to them through cellular adhesion and prevent groups of cells that must be separated from association. It also regulates and controls chemical communication between cells and ensures that cells do not receive too much unnecessary stimulus.

cell adhesion processes vary according to the type of organism or other substances such as viruses. This is a common processin eukaryotic organisms and is used for many purposes such as tying some specialized cells if necessary. It also occurs in procaryotes such as bacteria; The bacteria must first be tied to the host before it can infect it. Adhesion molecules in bacteria and other prokaryotes are usually called adhesions. Even viruses use cellular adhesion, although they are not usually considered organisms; They use adhesion to bind to cells that attack and control.
