Objective: To observe the changes of CD4+CD25+FoxP3 and IL-2, IL-6, IL-10, TNF-α inflammatory factors in the peripheralrnblood of the early PD patients and to further explore the correlations about CD4+CD25+FoxP3 and IL-2, IL-6, IL-10, TNF-αrninflammatory factors in peripheral blood of the early PD patients whether the level of CD4+CD25+FoxP3 and IL-2, IL-6, IL-10,rnTNF-αin different years, sex, grade and depression or not is different.rnMethods: CD4+CD25+FoxP3 were measured in 15 PD patients by the direct immunofluroscent staining technique and whichrnrelated inflammatory factors were measured by ELISA and compared with 30 normal controls.rnResults: The levels of CD4+CD25+FoxP3 in PD were depressed as compared with healthy controls (p<0.01). The levels of IL-2,rnIL-6, IL-10 and TNF-α in PD were higher than healthy controls (p<0.05). Different ages, different grade, presence or absencernof depression among PD patients, peripheral blood CD4+CD25+FoxP3 and which related inflammatory factors were notrnsignificantly different (p>0.05). IL-10 was significantly different between men and women in the PD group, the female level ofrnIL-10 was higher than the male (p<0.05), CD4+CD25+FoxP3 and the rest of the inflammatory factors were not different (p>0.05),rnthe changes of CD4+CD25+FoxP3, IL-2, IL-6, IL-10 and TNF-α in peripheral blood were in no significant correlation comparedrnwith age, sex, grade and depression.rnConclusion: CD4+CD25+FoxP3 immune functional decline and imbalance of IL-2, IL-6, IL-10 and TNF-α inflammatoryrnfactor were observed in early PD patients. The cellular immune function in patients was no significant among different ages,rndifferent classification and depressive symptoms or not but the level of IL-10 exists difference between male and female groups,rnCD4+CD25+FoxP3 and IL-2, IL-6, IL-10, TNF-α may be involved in the pathogenesis of early Parkinson’s disease in thernpathophysiology and pathogenesis of PD has played a certain role.
