CD28 (Cluster of Differentiation 28) is one of the proteins expressed on T cells that provide co-stimulatory signals required for T cell activation and survival. T cell stimulation through CD28 in addition to the T-cell receptor (TCR) can provide a potent signal for the production of various interleukins (IL-6 in particular). CD28 is the receptor for CD80 (B7.1) and CD86 (B7.2) proteins. When activated by Toll-like receptor ligands, the CD80 expression is upregulated in antigen-presenting cells (APCs). The CD86 expression on antigen-presenting cells is constitutive (expression is independent of environmental factors). It is generally reported, that CD28 is expressed on 50% of CD8+ T cells and more than 80% CD4+ T cells in human, but during the course of activation some T cells lose this molecule. In general, CD28 is a primary costimulatory molecule for T cell activation.
流式分析
Flow cytometric analysis of Human CD28 expression on human PBMC (human peripheral blood mononuclear cell). Human PBMC were stained with Brilliant Violet 421™ Mouse Anti-Human CD3 antibody and either FITC Mouse IgG1 Isotype Control (Left panel) or SDT FITC Mouse Anti-Human CD28 Antibody (Right panel) at 5 μl/test. Flow cytometry and data analysis were performed using BD FACSymphony™ A1 and FlowJo™ software.
