We have previously shown that antibody titres to several heat-shock proteins (Hsps) are elevated in dyslipidaemic patients and subjects with established vascular disease. Obesity is known to be associated with raised serum inflammatory markers suggesting a state of heightened immune activation. Hence, we have investigated the association between indices of obesity and several Hsp antibody titres in healthy subjects. Subjects (n=170) were recruited from among employees at the University of Surrey and the Royal Surrey County Hospital, Guildford, UK. Of these subjects, 35 were obese with a body mass index (BMI)>/=30 kg/m(2) (19 male and 16 female subjects), 58 were overweight with 30>BMI>/=25 kg/m(2) (36 male and 22 female subjects) and 77 were of a normal weight with BMI<25 kg/m(2) (31 male and 46 female subjects). Overall, obese subjects had significantly higher plasma anti-Hsp-60 (P<0.001), anti-Hsp-65 (P<0.05) and anti-Hsp-70 (P<0.05) compared with overweight and normal weight subjects.
我们之前已经表明,血脂异常患者和已患血管疾病的受试者体内,针对几种热休克蛋白(Hsps)的抗体滴度会升高。众所周知,肥胖与血清炎症标志物升高有关,提示免疫激活增强的状态。因此,我们研究了健康受试者中肥胖指标与几种Hsp抗体滴度之间的关联。受试者(n = 170)从英国吉尔福德萨里大学和皇家萨里郡医院的员工中招募。在这些受试者中,35人肥胖,体重指数(BMI)≥30 kg/m²(19名男性和16名女性受试者),58人超重,30>BMI≥25 kg/m²(36名男性和22名女性受试者),77人体重正常,BMI<25 kg/m²(31名男性和46名女性受试者)。总体而言,与超重和体重正常的受试者相比,肥胖受试者的血浆抗Hsp - 60(P<0.001)、抗Hsp - 65(P<0.05)和抗Hsp - 70(P<0.05)水平显著更高。
