The Central Memory CD4 T Cell Isolation Kit was developed for the isolation of central memory CD4 T cells from human PBMCs in a two-step procedureCentral memory CD4 T cells are isolated based on the expression of CD197 CCR7 and the absence of CD45RA on these cells. CD4 central memory T cells play a critical role in the pathogenesis of simian immunodeficiency virus disease and the CCR5 density on the surface of CD4 T cells is an important factor in human. Author summary We show that memory CD4 T cell mediated protection against influenza A virus is independent of the signature multifunctional cytokine IL-2 that is thought to define the most protective memory cells.

Th1-polarised cells are responsible for control of intracellular pathogens such as viruses and some bacteria. Microbiota-reactive CD4 T memory TM cells are generated during intestinal infections and inflammation and can revert to pathogenic CD4 T effector TE cells resulting in chronicity of inflammatory bowel disease IBD. Furthermore CD4 T cell clones in the infant intestine are highly compartmentalized and have limited overlap with clones in the spleen or blood Bunders et al 2012 suggesting that the intestine might harbor a distinctive tissue-resident population of memory CD4 T cells prior to birth.
