Green; Transforming Growth Factor β1 Inhibits Fas Ligand Expression and Subsequent Activation-induced Cell Death in T Cells via Downregulation of c-Myc . Activation-induced cell death (AICD) is a process that regulates the size and the duration of the primary immune T cell response. Plaquenil for lupus reviews fatigue Chloroquine brand name in pakistan Chloroquine phopshate usp The role of perforin in cytotoxicity is controversial. This paper characterizes a novel monoclonal antibody anti-Phu against human perforin, using murine cell lines transfected with human perforin cDNA. The antibody specifically stains human perforin in transfected mouse CTLL-2. Perforin 1 Antibody A-2 is a mouse monoclonal IgG 1 kappa light chain provided at 200 µg/ml; specific for an epitope mapping between amino acids 529-554 at the C-terminus of Perforin 1 of human origin; recommended for detection of Perforin 1 of mouse, rat and human origin by WB, IP, IF and ELISA; blocking peptide, sc-373943 P The cultured spleen cells of mi/mi but not of tg/tg mice were defective in the perforin gene expression. In the CTLL-2 cytotoxic T cells, transactivation of the perforin gene promoter was enhanced by wild-type + MITF but suppressed by mi-MITF through a 9-mer NF-P motif, which has been established as a strong cis-acting element. We found that TGF-β1 decreased apoptosis of human T cells or T cell hybridomas after activation by anti-CD3. In this report, we investigated the mechanisms involved in the regulation of AICD by transforming growth factor β1 (TGF-β1). Perforin ctll-2 chloroquine SANTA CRUZ BIOTECHNOLOGY, INC.

Homozygous mutant mice demonstrate significantly reduced levels of perforin mRNA and protein in their NK cells. Co-transfection of wildtype MITF could enhance basal perforin promoter activity in CTLL-2 cells via the NF-P motif. Reciprocally, the mutant MITF attenuated its basal activity in those cells.
