mouse ... Cd152(12477) , Ctla4(12477)
Descripción general
The complement (C1q) and FcγR I binding sites of the Fcγ2a fragment allow the Fc portion of the fusion protein to effectively facilitate direct antibody directed cytotoxicity (ADCC) and complement directed cytotoxicity (CDC).
Acciones bioquímicas o fisiológicas
CD152 (CTLA4), a cell surface glycoprotein expressed at low levels on activated T cells, is a high affinity receptor for the costimulatory molecules CD80 (B7-1) and CD86 (B7-2). A related cell surface glycoprotein, CD28, binds to CD80 and CD86 with lower affinity. The soluble CD152/Fc chimeric fusion protein blocks the B7/CD28 signaling pathway by binding to CD80 and CD86.
Otras notas
The extracellular domain (160 amino acids) of mouse CD152 is fused to mouse IgG2a Fc domain.

Metastatic melanoma is a disease associated with poor prognosis, with a median survival reported to range from 6 to 9 months. Patients who are not candidates for surgical resection have an even worse expected survival. This is largely due to

To test the hypothesis that blockade of B7-triggered costimulation by donor cells could preclude allograft rejection, we coated crude islet allograft preparations in vitro for 1 h with a murine CTLA4/Fc fusion protein. Murine CTLA4/Fc blocks the proliferative response in

Murine dendritic cells (DCs) expressing indoleamine 2,3 dioxygenase (IDO) catabolize tryptophan and can suppress T cell responses elicited in vivo. Here, we identify specific subsets of splenic (CD11c+) dendritic cells competent to mediate IDO-dependent T cell suppression following CTLA4-mediated ligation

In mice, immunoregulatory APCs express the dendritic cell (DC) marker CD11c, and one or more distinctive markers (CD8alpha, B220, DX5). In this study, we show that expression of the tryptophan-degrading enzyme indoleamine 2,3 dioxygenase (IDO) is selectively induced in specific

Functional interactions between T and B lymphocytes are necessary for optimal activation of an immune response. Recently, the T lymphocyte receptor CD28 was shown to bind the B7 counter-receptor on activated B lymphocytes, and subsequently to costimulate interleukin 2 production
