What are the cellular adhesion molecules and what do they do?

Cell adhesion molecules (CAMs) are a subset of cell surface proteins that are involved in the binding of cells with other cells or with the extracellular matrix (ECM), in a process called cell adhesion. In essence, CAMs help cells stick to each other and to their surroundings.

What is the role of cell adhesion molecules in cell signaling?

Cell adhesion links cells in different ways and can be involved in signal transduction for cells to detect and respond to changes in the surroundings. Other cellular processes regulated by cell adhesion include cell migration and tissue development in multicellular organisms.

What is selectin and integrin?

Selectins and some of their counter-receptors function also as signal-transducing receptors, significantly contributing to leukocyte and endothelial cell activation. Integrins represent a large family of adhesion receptors that are widely expressed and mainly interact with extracellular matrix components.

What are examples of adhesion molecules?

Adhesion molecules are cell surface proteins that mediate the interaction between cells, or between cells and the extracellular matrix (ECM). There are four families of adhesion molecules: immunoglobulin-like adhesion molecules, integrins, cadherins and selectins.

How do you increase cell adhesion?

Various groups have reported the enhancement of cell adhesion by increasing surface roughness at the nanometer scale using techniques such as sand blasting. It has also been shown that cell adhesion may be improved by chemical grafting of adhesion peptides such as Arg-Gly-Asp to material surfaces.

How do cells attach to biomaterials?

Cells adhere to surfaces through adhesion proteins (i.e. fibronectin, collagen, laminin, vitronectin) using specific cell receptors, called integrins, attached to the cell membrane.

What is cell adhesion and why is it important?

Cell adhesion is involved in stimulating signals that regulate cell differentiation, cell cycle, cell migration, and cell survival [4]. Cell adhesion is also essential in cell communication and regulation, and becomes of fundamental importance in the development and maintenance of tissues.

What are the roles of cell adhesion molecules?

Cell adhesion molecules including receptors of the immunoglobulin superfamily and integrins are of crucial importance in mediating these processes.

What are the adhesion molecules in the ECM?

Adhesion molecules are cell surface proteins that mediate the interaction between cells, or between cells and the extracellular matrix (ECM).

How are selectins involved in transient cell adhesion?

Selectins are a family of specialised CAMs involved in transient cell–cell adhesion occurring in the circulatory system. They mainly mediate the movement of white blood cells (leukocytes) in the bloodstream by allowing the white blood cells to “roll” on endothelial cells through reversible bindings of selections.

How is cell adhesion mediated in the circulatory system?

Adhesion mediated by selectins. Selectins are a family of specialised CAMs involved in transient cell–cell adhesion occurring in the circulatory system. They mainly mediate the movement of white blood cells (leukocytes) in the bloodstream by allowing the white blood cells to “roll” on endothelial cells through reversible bindings of selections.
