VMIP-II for inducing dephosphorylation of CD8<+> T cells to form Tcm and application of vMIP-II in medicines

The invention discloses application of virus macrophage inflammatory protein vMIP-II for inducing dephosphorylation of CD8<+> T cells to form Tcm. The vMIP-II for inducing dephosphorylation of the CD8<+> T cells to form the Tcm is developed in a laboratory and is verified by the National Institute for Control of Pharmaceutical and Biological Products. According to the invention, the CD8<+> T cellsare researched through a rhesus SIV infection model. The research finds that: the vMIP-II can enable Tcm to be proliferated depending on the dosage of the vMIP-II, and the differential gene of the proliferative cell is mainly enriched in a chemokine receptor and a phosphorylation pathway. The research further finds that: the proliferation is as follows: the vMIP-II closes a CD8<+> T chemokine receptor, promotes low expression of G protein, reduces the concentration of intracellular Ca<2+> and mitochondrial membrane potential, inhibits phosphorylation related genes, and promotes low expressionof phosphorylated proteins ERK1 / 2 and Akt, so that a CD8<+> T phosphorylation signal is weakened, metabolic reprogramming is carried out, and the CD8<+> T is converted into the Tcm. Therefore, the discovery of the vMIP-II action mechanism provides a brand-new strategy for drug research and development of HIV / SIV infected AIDS, provides a new means for adoptive immunotherapy of virus resistance and tumor resistance, and has important clinical application value.
