| CD2 | <immunology> Glycoprotein members of the immunoglobulin superfamily which participate in T-cell adhesion and activation. They are expressed on most peripheral T-lymphocytes, natural killer cells, and thymocytes, and function as co-receptors or accessory molecules in the T-cell receptor complex. (12 Dec 1998) |
|---|---|
| CD20 | <immunology> Unglycosylated phosphoproteins expressed only on B-cells. They are regulators of transmembrane calcium conductance and thought to play a role in B-cell activation and proliferation. (12 Dec 1998) |
| CD26 | <enzyme, immunology> Cell-surface glycoproteins and serine protease, also known as dipeptidyl-peptidase IV, that play a role in t-lymphocyte activation. Cd26 binds to adenosine deaminase on the T-cell surface. Registry number: EC 3.4.14.5 (12 Dec 1998) |
| CD27 | <immunology> Dimeric membrane glycoproteins found on most T-lymphocytes. Activation of T-cells by the antigen receptor increases CD27 surface expression. (12 Dec 1998) |
| CD28 | <immunology> T-cell differentiation antigens that serve as the receptors for the b7 antigen (antigens, CD80) which modulates T-cell lymphokine production. (12 Dec 1998) |
| CD29 | <immunology> Integrin beta-1 chains which are expresssed as heterodimers noncovalently associated with specific alpha-chains of the CD49 family (CD49a-f). Cd29 is expressed on resting and activated leukocytes and is a marker for total very late activation antigens on cells. (barclay et al., the leukocyte antigen factsbook, 1993, p164) (12 Dec 1998) |
| antigens, CD2 | <immunology> Glycoprotein members of the immunoglobulin superfamily which participate in T-cell adhesion and activation. They are expressed on most peripheral T-lymphocytes, natural killer cells, and thymocytes, and function as co-receptors or accessory molecules in the T-cell receptor complex. (12 Dec 1998) |
