Positive Costimulatory Receptors: ICOS

ICOS binds to another member of the growing B7 family, ICOS-ligand (ICOS-L), which is also expressed on a subset of activated APCs.

ICOS plays a key role in maintaining the activity of already differentiated effector and memory T cells.

The overall effect of migration is twofold: 

1.it prevents populations from becoming genetically different from one another, 

2.it increases genetic variation within populations.
