背景：Inducible co-stimulator ligand （ICOSL）, also known as B7-H2, is a member of the B7 family of co-stimulatory molecules related to B7-1 and B7-2.
It is a transmembrane glycoprotein with extracellular IgV and IgC domains, and binds to ICOS on activated T cells, thus delivers a positive costimulatory signal for optimal T cell function.
The structural features of ICOSL are crucial for its costimulatory function.
Present study shows that ICOSL displays a marked oligomerization potential, resembling more like B7-1 than B7-2.
B7-H2-dependent signaling may play an active role in a proliferative response rather than in cytokine and chemokine production.
The CD28/B7 and ICOS/B7-H2 pathways are both critical for costimulating T cell immune responses.
Deficiency in either pathway results in defective T cell activation, cytokine production and germinal center formation.
