Abstract: Provided are an immune cell treated by means of a magnetic field and the use thereof. A medium static magnetic field with an intensity of 0.3 T can promote the secretion of granzymes and cytokines of mouse CD8+ T cells, increase the level of ATP and mitochondrial respiration, and up-regulate the expression of mitochondrial respiratory chain related genes Uqcrb and/or Ndufs6. In addition, magnetic receptor candidate genes Isca1 and Cry1/Cry2 are involved in regulating the expression of Uqcrb and/or Ndufs6. An in-vivo experiment shows that the static magnetic field can inhibit the growth and development of tumors by means of promoting the secretion of the granzymes and cytokines of the CD8+ T cells. A killing ability test shows that the static magnetic field treatment can enhance the killing ability of the CD8+ T cells, and infusion of the CD8+ T cells treated by means of the magnetic field back into a tumor-grafted mouse has an anti-tumor effect.
