Expressions of Toll-like receptor 3 and 9 in peripheral mononuclear cells from patients with herpes zoster / 中华皮肤科杂志

ABSTRACT

ObjectiveTo investigate the roles of Toll-like receptor (TLR) 3 and 9 in herpes zoster (HZ).Methods Venous blood samples were collected from 40 patients with HZ and 16 normal human controls. Flow cyometrywas usedto detect the expressionsof TLR3and TLR9inperipheralblood mononuclear cells(PBMCs) from these subjects.ResultsThe percentages of PBMCs expressing TLR3 and TLR9 were significantly higher in patients than in normal human controls(both P ＜ 0.01).The expression levels of TLR3 and TLR9 in PBMCs were negatively correlated with the age of onset(r =-6.23,-5.88respectively,both P ＜ 0.01 ),but uncorrelated with gender or age.There was a significant difference in the expression levels of TLR3 and TLR9 in PBMCs between different age groups ( ＜ 40 years,40-50 years,＞ 50 years) of patients with HZ(F =3.410,P ＜ 0.01 ),with the strongest expression observed in patients younger than 40 years.ConclusionTLR3 and TLR9 may participate in the pathogenesis of HZ.
