[Effect of CD4(+) T cell surface CD1d molecules on progression of multiple sclerosis in mouse experimental autoimmune encephalomyelitis model].

Objective To investigate the effect of CD1d molecules on the surface of CD4+ T cells on the progression of experimental autoimmune encephalomyelitis (experimental, allergic, encephalomyelitis, EAE) mouse models. Methods EAE model of C57BL/6 mice was established, Splenic cells were isolated at different stages of the progression of the disease.The proportion of CD1d+ cells on the surface of activated and non activated CD4+ T cells was detected by flow cytometry. Results The proportion of CD1d+ cells in the control group (normal group and complete Freund′s adjuvant (CFA) group), in the peak and recovery period of disease in the EAE group were compared.The proportion of CD1d+ cells in the control group was (8.98 ±0.36)%, and the proportion of CD1d+ cells in the peak and recovery period of disease in the EAE group were respectively (2.14±0.15)% and (13.80±0.84)%.The differences were statistically significant difference (P<0.05). Conclusion The trend of the proportion of CD4+ T cells expressing CD1d molecules during the course of EAE pathogenesis is verified, which lays a foundation for further study on the interaction between CD4+ T cells and NKT cells in the progression of EAE models.
