WebA cytokine is a chemical messenger that regulates cell differentiation (form and function), proliferation (production), and gene expression to affect immune responses. At least 40 types of cytokines exist in humans that differ in terms of the cell type that produces them, the cell type that responds to them, and the changes they produce. WebExpansion of antigen-specific cytokine-secreting T cells This application protocol describes how to expand antigen-specific T cells which have been isolated using the MACS® Cytokine Secretion Assay after restimulation with antigen. These T cells are therefore of a memory phenotype. WebAn antigen-presenting cell ( APC) or accessory cell is a cell that displays antigen bound by major histocompatibility complex (MHC) proteins on its surface; this process is known as antigen presentation. T cells may recognize these complexes using their T cell receptors (TCRs). APCs process antigens and present them to T-cells. how to switch off firewall in windows 10
