银屑病表皮热休克蛋白27、70、60的表达

Expression of Heat Shock Proteins 27,70 and 60in Psoriatic Epidermal Keratinocytes

目的探讨热休克蛋白(HSP)在银屑病发病中的作用。方法通过免疫组化和图像分析检测了25例银屑病患者治疗前后皮损、非皮损区表皮组织中HSP27、HSP70和HSP60的表达,并与6例正常人作对照。结果HSP27、HSP70在非皮损、正常人表皮中呈基础表达,在银屑病患者皮损中的表达很弱,治愈后表皮中HSP27、HSP70的表达又恢复;HSP60的表达在银屑病皮损组表皮中均为阳性,而银屑病非皮损组、治愈后组表皮中及正常人对照表皮组织中HSP60的表达均阴性。结论热休克蛋白在银屑病应激保护机制中可能发挥一定的作用。

Objective To investigate the role of heat shock poteins(HSPs)in the pathogenesis of psoriasis.Methods Expression of HSP27,HSP70and HSP60was detected by immunohistochemical and image analysis in epidermal keratinocytes of pre-and post-treatment psoriatic lesional,and non-lesional skin in25psoriatic patients and6healthy controls.Results There was constitutive expression of HSP27and HSP70in epidermal keratinocytes of psoriatic non-lesional skin and normal controls,and the weak expression in psoriatic lesions.There was expression of HSP60in keratinocytes of psoriatic skin,but no expression of HSP60in non-lesional and normal skin.Expression of HSP27and HSP70recovered gradually in post-treatment psoriatic lesions,and no expression of HSP60was observed in lesional skin after treatment.Conclusion HSPs may play a certain role in psoriatic stress protective mechanism.
