ICOS binds specifically to its ligand (ICOS-L), also known as B7-related protein-1 (B7RP-1), which is expressed constitutively on B cells. Inducible costimulator (ICOS), a prototypic T cell costimulator, is induced on activated T cells. ICOS regulates T cell activation and Th cell differentiation and is principally involved in humoral immune responses. Previous work showed that T cell accessory function is modulated by the plant-derive … 2006-06-15 · Numerous studies have revealed that the B7.1/B7.2 – CD28 and B7RP-1 – ICOS (Inducible COStimulator) pathways provide crucial costimulatory signals to T cells. We have compared the contribution of these pathways during primary and effector responses, in vitro and in vivo, molecularly as well as functionally. Expression of ICOS on responding TCR transgenic CD4 + T cells was also assessed, using low numbers of SM1 T cells to model the population size of endogenous naive T‐cell pools 32.

2016-07-27 · ICOS binds specifically to its ligand (ICOS-L), also known as B7-related protein-1 (B7RP-1), which is expressed constitutively on B cells. In vivo, the interaction of ICOS with ICOS-L is critical for T cell-dependent B cell responses. In the absence of ICOS, germinal center formation is impaired and immunoglobulin class switching is defective. 2018-01-11 · First, we demonstrate that the ICOS ICD dramatically enhanced the in vivo persistence of CAR-expressing CD4 + T cells that, in turn, increased the persistence of CD8 + T cells expressing either CD28- or 4-1BB–based CARs. 2013-12-02 · Inducible co-stimulator (ICOS) is a member of CD28/Cytotoxic T-lymphocyte Antigen-4 (CTLA-4) family and broadly expressed in activated CD4+ T cells and induced regulatory CD4+ T cells (CD4+ iTreg).

The percentage of CD4 + CD25 + regulatory T cells in mice after magnetic bead separation was >95%. Tregs were cultured with anti-CD3 antibody, anti-CD3 + anti-CD28 antibody or anti-CD3 + anti-ICOS antibody for 2, 4 or 6 days, and apoptosis was examined by flow cytometry with Annexin-V Apoptosis Detection Kit FITC. 2003-07-15 · ICOS is inducible within 48 hours of T cell activation on both CD4 + and CD8 + cells after CD28 signaling , whereas cytotoxic T lymphocyte antigen-4 (CTLA-4) ligation prevents its upregulation .

Children with type 1 diabetes Inducible T-cell costimulator (ICOS), a T-cell costimulatory receptor, is a promising therapeutic target, not only because it is expressed by malignant T cells in CTCL but also because of its connection with the suppressive activity of regulatory T (Treg) cells.
