ABSTRACT
Objective To investigate the expressions of heat shock protein(HSP)90α and HSP90β in peripheral blood mononuclear cells (PBMC) in myasthenia gravis (MG) children before and after glucocorticoid (GC) treatment,and normal control groups.Methods Fresh bloods were collected from 20 cases of children with MG before and after treatment and 19 healthy children.PBMCs were isolated,followed by measurement of the expression levels of HSP90α and β by immunocytochemistry,and HSP90α and β mRNAs by reverse transcription and polymerase chain reaction (RT-PCR).Results The positive cell ratio of HSP90α andβ of MG children before and after of GC treatment was significantly higher than control groups (P < 0.05),and their mRNA expression levels was higher than control groups (P < 0.05).HSP90β in MG children after GC treatment was mainly expressed in the nucleus(P < 0.05).Conclusions HSP90α and β in PBMC of MG children before and after GC treatment were significantly higher than those of normal control groups.HSP90β in MG Children after GC treatment was significantly increased.The present results suggest HSP90β promote GC receptor binding and enhance GC transportation,which promotes and strengthens the physiological and pharmacological effects of GC to improve the clinical symptom of MG children.
