surface markers on T and B cells

CD2

It is involved in T cells activation

CD3

Associated with T cell antigen receptor; role in TCR signal transduction

CD4

Coreceptor for MHC-II

receptor for HIV

CD5

Positive or negatice modulation of T and B receptor signaling

CD8

Coreceptor for MHC class I

CD10

Protease; marker for pre B CALLA

CD16

Low affinity for Fc cell receptor, mediates phagocytosis and ADCC

Cd19

Part of B cells Macrophages Coreceptor, signal transduction molecules that regulates B cell development and activation

CD21

Receptor for complement component CD3

Part of B cell receptir and Cd19

CD23

Regulation of igE synthesis; triggers release of IL1, Ik6, and GM-CSF from monocytes

CD25

Receptor for Il2

CD44

Adhesion molecule mediating homing to peripheral lymphoid organs

CD45R

Essential in T and B cells Macrophages antigen- stimulated activation

CD94

Subunit of NKG2- a complex involved in the inhibition of NK cell antibody
