CD4 + T cells play central roles in adaptive immunity, driving appropriate immune responses to invading pathogens of diverse types. Four major CD4 + T cell subsets, Th1, Th2, Th17, and Treg cells are differentiated from naïve CD4 + T cells upon ligation of their T cell receptors with antigens, depending on the cytokines they receive. WebThis protocol is intended for physiological activation of human T cells, e.g. CD4+ T cells, CD8+ T cells, polyclonal T cells, or antigen specific T cells. Downstream Applications. The activated T cells can be analyzed shortly after activation (for transfection/ transduction or to study e.g. TCR signaling, proteomics or gene expression). mhlw guidance
