polyclonal anti-thymocyte globulin (atg) is used as an immunosuppressive agent in the treatment of aplastic anemia (aa). serum sickness is a recognized side effect of atg. we observed abnormal skin manifestation in patient with aplastic anemia who had been treated with atg. we conclude that abnormal immune function caused by aplastic anemia and atg and corticosteroids may aggravate the signs of...

 Abstract Background: Lymphoproliferative disorders are among the most serious and potentially fatal complications of chronic immunosuppression in kidney transplant recipients. The principle risk factors for development of PTLD are the degree of overall immunosuppression and the EBV serostatus of the recipient. In this study, the risk of PTLD in kidney transplant recipients who received Anti- L...

BACKGROUND Polyclonal antihuman thymocyte rabbit IgGs (antithymocyte globulin [ATG]) are popular immunosuppressive drugs used to prevent or treat organ or bone-marrow allograft rejection, graft versus host disease, and autoimmune diseases. However, animal-derived glycoproteins are also strongly immunogenic and rabbit ATG induces serum sickness disease in almost all patients without additional i...

Antithymocyte globulin (ATG) and antilymphocyte globulin (ALG) are effective therapies in aplastic anemia; their mechanism of action is undefined. We assayed multiple properties of ATG and ALG to address the biological and immunological bases for differences between ATG and ALG and lot variation. In addition, we studied a lot reported to be inactive in an American clinical trial; however in ret...

Humans have circulating antibodies against diverse glycans containing N-glycolylneuraminic acid (Neu5Gc) due to function-loss mutation of the CMAH gene. This xenogenic non-human carbohydrate is abundant in red meat, xenografts and biotherapeutics. Low levels of diet-derived Neu5Gc is also present on normal human endothelial cells, and together with anti-Neu5Gc antibodies could potentially media...

Background The RAS/MAPK pathway has emerged as a critical for therapeutic targeting in spectrum of solid tumor and hematological malignances. Inhibitors MAPK targets, such RAS, BRAF, or MEK have been approved the treatment cancer either monotherapy combination. However, there no drug ERK1/2, terminal kinases Ras-Raf-MEK-ERK signal transduction cascade. combination ERK1/2 inhibitor checkpoint in...

BACKGROUND The therapeutic efficacy of horse antilymphocyte globulins (ALG) or of rabbit antithymocyte globulins (ATG), used for both the prevention and treatment of allograft rejection has been well documented. However, clinical use of these heterologous antibodies can result in the production of antibodies against horse or rabbit proteins and in the development of serum sickness via circulati...

Polyclonal anti-human thymocyte globulins (ATG) have been recently shown to significantly reduce the incidence of graft versus host disease (GVHD) post allogeneic stem cell transplantation (HSCT) from both sibling and unrelated donors. Induction of regulatory T cells has been suggested as one of the possible mechanisms. The aim of current study was to further characterize the T cell populations...
