According to the invention, experimental autoimmune neuritis is used as an experimental environment to research intervention effect of zidovudine on the immune system. It is found through experiments that zidovudine can increase expression quantity of nuclear transcription factor 2 and heme oxygenase 1 so as to induce differentiation of M1-type macrophage to M2-type macrophage and furthermore promote neighboring cell proliferation and tissue repairing by the utilization of cytokines released by the M2-type macrophage.
