[The immunostimulatory study on peripheral blood mononuclear cell and CD4+ T lymphocyte of HBV infections that were activated by CpG oligonucleotide].
OBJECTIVE
To study the effects of CpG oligodeoxyribonucleotide (ODN) as adjuvant on the immune responses in PBMC and CD4+ T cell with chronic hepatitis B virus.


METHODS
The selected 20 infections were averagely divided two groups. The frequency of IFN-gamma secreting PBMC and CD4+ T cell in immune tolerant phase and in the immune clearance phase that had stimulated by CpG ODN, HBsAg and Mixture [CpG ODN + HBsAg] were analyzed by enzyme linked immune spot (ELISOT).


RESULTS
The PBMC and CD4+ T cell were differently incubated by CpG ODN, HBsAg and M [CpG ODN + HBsAg]. The number of IFN-gamma spot differently are 3 +/- 8, 339 +/- 429, 375 +/- 496, 1 +/- 4, 5 +/- 16 and 5 +/- 12; the results of immume tolerance are 3 +/- 8, 361 +/- 153, 375 +/- 276, 0 +/- 2, 2 +/- 2 and 4 +/- 4; but the results of immune clearance are 3 +/- 21, 289 +/- 345, 405 +/- 656, 2 +/- 14, 8 +/- 40 and 7 +/- 30. The IFN-gamma spots statistical analysis of PBMC were differently incubated by HBsAg and M, the total is P = 0.720, The IFN-gamma spots statistical analysis of CD4+ T cell were differently incubated by HBsAg and M, the total is P = 0.890, The IFN-gamma spots statistical analysis of PBMC and CD4+ T cell were differently incubated by M, the total is P = 0.000.


CONCLUSIONS
The ability that CpG ODN can not significantly increase the IFN-gamma secreting of PBMC and CD4+ T cell that were incubated by HBsAg to the infection in immune tolerant phase and in the immune clearance phase, but the PBMC outweighed The CD4 T cell.
