Abstract:
Objectives To investigate the expression and diagnostic value of 14-3-3 protein in brains of patients with sporadic Creutzfeldt-Jakob disease(sCJD).Methods 14-3-3 protein was immunohistochemically analyzed in tissue from the frontal lobe of 5 patients with sCJD and 4 non-CJD eases Using 14-3-3 ?and ?antibodies with reference to the results of KB,GFAP and PrP detection.Results The expressions of 14-3-3 protein in five brains of sCJD were more obviously,mostly in gray matters and astrocytes in three cases.The concentration was related to PrP deposition type,but not related to prion protein genotype.Except few expression of 14-3-3 protein in neurous of two cases of acute contusion,there were no expression in the other two cases in control group.Conclusions The expression of 14-3-3 protein in brain is useful to pathological diagnosis of CJD.
