BACKGROUND After renal transplantation, many patients experience adverse effects from maintenance immunosuppressive drugs. When these adverse effects occur, patient adherence with immunosuppression may be reduced and impact allograft survival. If these adverse effects could be prospectively monitored in an objective manner and possibly prevented, adherence to immunosuppressive regimens could be...
Certain polysaccharides have been shown to inhibit the antibody response of rabbits to the common enterobacterial antigen (CA). The present investigation revealed that striking differences exist in the immunosuppressive effects of enteric bacteria and their lipolysaccharides (lps), depending upon CA production by the strains. Mixtures of immunogenic strains (Escherichia coli F2378 [R4], E. coli...
A study in mice implicates a cholesterol derivative in damping down the inflammatory response mediated by interleukin-1β and explaining, at least in part, the immunosuppressive effect of type I interferon, which is used in the treatment of multiple sclerosis.
2-Amino-2-[2-(4-octylphenyl)]-1,3-propanediol hydrochloride (FTY720) is a potent immunosuppressant which has been approved by the Food and Drug Administration (FDA) as a new treatment for multiple sclerosis. As an immunosuppressant, it displays its anti-multiple sclerosis, immunosuppressive effects by activating sphingosine-1-phosphate receptors (S1PRs). In addition to the immunosuppressive eff...
Regulatory T cells (Tregs) are physiologically designed to prevent autoimmune disease and maintain self-tolerance. In tumour microenvironments, their presence is related to a poor prognosis, and they influence the therapeutic outcome due to their capacity to suppress the immune response by cell-cell contact and to release immunosuppressive cytokines. In this study, we demonstrate that Treg immu...
BACKGROUND Recent studies with bone marrow (BM)-derived Mesenchymal Stromal Cells (MSC) in transplant recipients demonstrate that treatment with MSC is safe and clinically feasible. While BM is currently the preferred source of MSC, adipose tissue is emerging as an alternative. To develop efficient therapies, there is a need for preclinical efficacy studies in transplantation. We used a unique ...
Abstract: The ethanol extract of Cynanchum ascyrifolium Matsum. showed significant anti-inflammatory and immunosuppressive activities with dose dependent manner using in vitro experiments. Then, the bioassay-guided ethanol extract lead to identification of four active compounds, namely ursolic acid (1), maslinic acid (2), cynanoside A (3) and syringaresinol (4). Among these compounds, cynanosid...
Chronic HBV infection is a dynamic state of interaction between HBV, hepatocytes, and the immune system of the host. A series of reactivation flares and remissions may occur due to multiple causes. Among them, spontaneous reactivation and immunosuppressive drugs including steroids or cancer chemotherapy are well known. This is due to immune-mediated destruction of HBV-expressing cells following...
