Abstract:
Objective To study the possible molecular mechanism of IL-10 in promoting Chlamydia muridarum infection in mice. Methods C57BL/6 wild-type and IL-10 gene knockout ( IL-10-/-) mice were infected with Chlamydia muridarum. Indirect immunofluorescence assay was used to detect the growth of Chlamydia muridarum in the intestinal and genital tracts. The severity of genital diseases was assessed by hydrosalpinx scoring. Expression of IFN-γand IL-2 in blood was measured by ELISA. Re-sults Compared with the wild-type group, Chlamydia clearance in the intestinal and genital tracts of IL-10-/- mice was significantly faster, and the expression of IFN-γ and IL-2 increased significantly. In addi-tion, wild-type mice showed more serious hydrosalpinx. Conclusions IL-10 delays Chlamydia trachomatis clearance and promotes Chlamydia infection through inhibiting the expression of IFN-γ and IL-2, which ag-gravates hydrosalpinx.
