Abstract:
Objective To analyze and evaluate the expression and significance of costimulatory molecules CD 28 ,CTLA-4 ,CD86 , CD80 mRNA in peripheral blood mononuclear cells of the patients with HBV chronic change .Methods The levels of costimulatory molecules CD28 ,CTLA-4 ,CD86 ,CD80 mRNA in peripheral blood mononuclear cells were detected in 24 cases of chronic hepatitis B (CHB) ,24 cases of liver cirrhosis(LC) ,28 cases of hepatocellular cancer(HCC) and 30 normal control(NC) subjects by real time quantitative PCR .Results Compared with the NC group ,costimulatory molecule CD28 mRNA level in the CHB group was signifi-cantly decreased(t= -2 .11 ,P<0 .05);CTLA-4 mRNA level in different diseases groups was decreased to different degrees :the CHB group(t= -2 .52 ,P<0 .05) ,the LC group(t= -2 .11 ,P<0 .05) and the HCC group(t= -2 .56 ,P<0 .05);CD86 mRNA level in different diseases groups was decreased to different degrees too :the CHB group(t= -3 .68 ,P<0 .01) ,the LC group(t= -2 .99 ,P<0 .01) and the HCC group(t= -4 .42 ,P< 0 .01);CD28/CTLA-4 mRNA level was significantly increased in the HCC group(t= 2 .12 ,P< 0 .05);CD80/CD86 mRNA level was significantly increased to different degrees with the progress of HBV chronic change:the CHB group(t=2 .10 ,P<0 .05) ,the LC group(t=2 .59 ,P<0 .05) and the HCC group(t=3 .74 ,P<0 .01) . Conclusion The expression abnormality of CD28/B7 family costimulatory molecules mRNA in HBV infectious patients may be closely related with the immune dysfunction and the development and progression of the chronic change .
