Expression of indoleamine 2.3-dioxygenase by tumors induces local and systemic immunosuppressive effects in a murine melanoma model
Indoleamine 2,3-dioxygenase (IDO) is found in the majority of human tumors and has been described as an important contributor to the development of an immunosuppressive tumor microenvironment that blocks the action of cytotoxic antitumor effector T cells. In order to delineate the mechanisms of IDO-induced immunosuppression in melanoma, we initially focused on murine transplantable and spontane...

متن کاملLocal Expression of Indoleamine 2,3 Dioxygenase in Syngeneic Fibroblasts Significantly Prolongs Survival of an Engineered Three-Dimensional Islet Allograft
OBJECTIVE The requirement of systemic immunosuppression after islet transplantation is of significant concern and a major drawback to clinical islet transplantation. Here, we introduce a novel composite three-dimensional islet graft equipped with a local immunosuppressive system that prevents islet allograft rejection without systemic antirejection agents. In this composite graft, expression of...
متن کاملHigh expression of indoleamine 2,3-dioxygenase gene in prostate cancer.
Arginase 2, inducible- and endothelial-nitric-oxide synthase (iNOS and eNOS), indoleamine 2,3-dioxygenase (IDO) and TGF-beta, might impair immune functions in prostate cancer (PCA) patients. However, their expression was not comparatively analysed in PCA and benign prostatic hyperplasia (BPH). We evaluated the expression of these genes in PCA and BPH tissues. Seventy-six patients (42 BPH, 34 PC...
متن کاملImpact of immunosuppressive agents on the expression of indoleamine 2,3-dioxygenase, heme oxygenase-1 and interleukin-7 in mesangial cells
Chronic allograft nephropathy (CAN) is a major cause of graft loss following kidney transplantation and may result from the interactions of various immune and non-immune factors. The aim of the present study was to establish an in vitro model of glomerular mesangial cell injury in order to examine the gene expression levels of indoleamine 2,3-dioxygenase (IDO), heme oxygenase-1 (HO-1) and inter...
