The aim of this study was to investigate the effects of TLR2, TLR9, CD4(+)CD25(+) regulatory T cells (Treg) and transcription factor FoxP3 in the pathogenesis of children with infectious mononucleosis (IM). Thirty-five acute IM patients admitted in our hospital from April 2010 to January 2011 were enrolled in this study. Thirty-five healthy subjects were taken as control. The thirty-five patients before treatment were considered as patients in acute stage, after treatment and without clinical symptom they were thought as patients in recovery stage. The expression levels of TLR2, TLR9 and FoxP3 mRNA were detected by real time PCR using SYBR Green I. The expression of T lymphocyte subset CD4(+)CD25(+) in peripheral blood mononuclear cells was detected by flow cytometry. The results showed that the relative levels of TLR2 mRNA (4.03 ± 0.56), TLR9 mRNA (8.88 ± 1.56) in peripheral blood mononuclear cells of IM patients in acute stage were significantly higher than those of the controls [TLR2 mRNA (2.22 ± 0.57), TLR9 mRNA (3.63 ± 1.30)] and IM patients in recovery stage [TLR2 mRNA (2.76 ± 0.83), TLR9 mRNA (5.34 ± 1.60)] (P < 0.01). The result of CD4(+)CD25(+) (2.38 ± 1.32%) and relative level of FoxP3 mRNA(2.82 ± 0.90) in peripheral blood mononuclear cells of IM patients in acute stage were lower than those of the control [CD4(+)CD25(+) (7.85 ± 1.97%), FoxP3 mRNA (4.65 ± 1.23) ] (P < 0.01). There was no significant difference in CD4(+)CD25(+) (6.81 ± 1.84%), FoxP3 mRNA(4.11 ± 1.37) levels between IM patients in recovery stage and the controls (P > 0.05). It is concluded that the expression of CD4(+)CD25(+)regulatory T cells is reduced, and its special transcription factor FoxP3 mRNA is down-regulated, but expression levels of TLR2 mRNA, TLR9 mRNA are up-regulated in IM patients of acute stage.
