Follicular B helper T cells (also known as just follicular helper T cells or T FH), are antigen-experienced CD4 + T cells found in the periphery within B cell follicles of secondary lymphoid organs such as lymph nodes, spleens and Peyer's patches, and are identified by their constitutive expression of the B cell follicle homing receptor CXCR5.

In addition to its role in directing effector T cell ICOS-L is activated in several types of cancers to maintain immunosuppressive CD4+ T cell subsets, such as regulatory T cells (Tregs). ICOS-L over-expression is associated with tumour progression and poor overall survival. Introduction. Inducible T-cell costimulator (ICOS) is a homodimeric protein with a molecular weight of approximately 55∼60 kD that was originally discovered on the surface of T cells upon T-cell receptor (TCR) stimulation in 1999 ( 1 ). ICOS binds specifically to its ligand (ICOS-L), also known as B7-related protein-1 (B7RP-1), which is expressed constitutively on B cells.

It binds to an ICOS ligand expressed by B-cells, macrophages, and DCs.52 Its function is clearly costimulatory for T-cell proliferation and cytokine secretion. 2008-12-21 · The costimulatory molecule ICOS is important for the development of both interleukin 17–producing and follicular T helper cells. Kuchroo and colleagues find that ICOS induces the transcription ICOS does not bind to B7‐1 or B7‐2, and CD28 does not bind to ICOS ligand; thus the CD28 and ICOS pathways do not cross‐interact on the cell surface. In vivo , ICOS is expressed in the medulla of the fetal and newborn thymus, in the T cell zones of tonsils and lymph nodes, and in the apical light zones of germinal centers (predominant expression).

Diseases associated with ICOS include Immunodeficiency, Common Variable, 1 and Common Variable Immunodeficiency . Among its related pathways are Downstream signaling events of B Cell Receptor (BCR) and Signaling by GPCR .

These co-stimulatory proteins have functions similar to, but not completely overlapping with, CD28. Recently, ICOS was described as an inducible CD28-related molecule with co-stimulatory functions on human T cells in vitro . Human ICOS is the ortholog of murine CRP-1 (CD28-related protein-1).
