Abstract:
Objective To screen immune molecules expressed on peripheral blood mononuclear cells (PBMCs) which arc related to the aggravation of chronc hepatitis B (CHB). Methods Real-time polymerase chain reaction (PCR) was employed to detect the relative expression of 39 immune molecules at mRNA level and then compare the differences between groups (control group, mild CHB group, moderate CHB group and severe CHB group). The investigated immune molecules included leukocyte differentiation antigens, chemokine receptors, apoptosis-related ligands and receptors,adhesion molecules and Toll like receptors. Scheffe model was used to compare the differences among all groups and Spearman rank correlation was used for correlation analysis. Results Among the 39 immune molecules, the expressions of tumor necrosis factor related apoptosis inducing ligand (TRAIL), TRAIL receptor (TRAIL-R) 2, CD64, CD30, CD27, CD28, L-selectin (CD62L),intercellular adhesion molecule-1 (ICAM-1), chemokine (C-X-C motif) receptor (CXCR) 2 were significantly increased in severe CHB group compared with those in control group ( 1.96, 2.13, 1.33,1.16, 1.57, 2.14, 2.03, 2. 10 and 2.09, respectively; all P＜0.05). The expressions of TRAIL,TRAIL-R2, CD64, CD30, CD27 were highly correlated with the expression of interferon gamma (IFN-γ) (r=0. 816, 0. 572, 0. 462, 0. 697 and 0. 793, respectively; all P＜0.01). The expressions of TRAIL-R2, CD64, CD30, CD62L, ICAM-1 were highly correlated with the expression of tumor necrosis factor alpha (TNF-α) (r=0. 494, 0. 588, 0. 568, 0. 968 and 0. 976, respectively; all P＜0.01). Conclusion The abnormal expression of TRAIL,TRAIL R2,CD64,CD30,CD27,CD28,CD62L,ICAM-1 and CXCR2 may play an important role in the pathogenesis and aggravatoin of hepatitis B.
