"Receptor Very Late Antigen" is commonly abbreviated as VLA and refers to a group of cell adhesion molecules found on the surface of immune cells. These molecules play a crucial role in mediating cell-cell interactions and are involved in various biological processes such as immune response and inflammation. While VLA is a specific term, there are several synonyms that can be used interchangeably. Some of these synonyms include integrins, cell adhesion receptors, leukocyte integrins, and very late activation antigens. These terms all describe the same group of molecules that are vital for immune cell function and communication within the body.
