Abstract

Objective To study the level of the Toll like-receptor mRNA expression on PBMCs from patients with the idiopathic thrombocytopenic purpura.Methods We performed quantitative real-time reverse transcription-polymerase chain reaction(SYBR Green Ⅰ fluorescent dye combination technique)analyses of PBMCs from 30 idiopathic thrombocytopenic purpura(ITP) patients and 30 healthy subjects,to estimate the relative levels of TLR2,TLR4,TLR6,TLR7 and TLR9 mRNA expression.Results Relative expression levels of TLR2 and TLR7 mRNAs in ITP group(n=30)were significantly higher than those in health control group(n=30)(P0.05).Conclusion Expressions of TLR2 and TLR7 mRNA are up-regulated in patients with ITP,which may play an important role in the pathogenesis of ITP.
