Ligand for the T-cell-specific cell surface receptor ICOS. Acts as a costimulatory signal for T-cell proliferation and cytokine secretion; induces also B-cell proliferation and differentiation into plasma cells. Could play an important role in mediating local tissue responses to inflammatory conditions, as well as in modulating the secondary immune response by co-stimulating memory T-cell function.

Isoform 1 is widely expressed (brain, heart, kidney, liver, lung, pancreas, placenta, skeletal muscle, bone marrow, colon, ovary, prostate, testis, lymph nodes, leukocytes, spleen, thymus and tonsil), while isoform 2 is detected only in lymph nodes, leukocytes and spleen. Expressed on activated monocytes and dendritic cells.

Isoform 1 highest expression in lymphoid tissues, such as spleen (mostly in the marginal zone), lymph nodes (particularly in the cortex and in both primary and secondary follicles), thymus (predominantly in the medulla) and Peyer patches (mostly in the follicles), lower levels in many non-lymphoid tissues, such as brain, heart, kidney, liver, lung, skeletal muscle and testis. Present on freshly isolated splenic B-cells, T-cells, dendritic cells and macrophages. The expression of isoform 2 is restricted to heart, spleen and kidney.
