NK細(xì)胞和NKT細(xì)胞在慢性乙型肝炎中的表型和功能特征
[Abstract]:Objective to detect the natural killing of (NK) cells, the proportion of natural killing T (NKT) cells, the level of NKG2D/NKG2A and the levels of interferon gamma (IFN- 緯) and tumor necrosis factor 偽 (TNF- 偽) in peripheral blood of patients with chronic hepatitis B (CHB). Methods (PBMC), flow cytometry was used to detect the proportion of NK,NKT cells to PBMC and the level of NKG2D,NKG2A in peripheral blood mononuclear cells (PBMCs) of CHB patients. The NKG2D,NKG2A levels were treated with phorpoester (PMA), brafepiditin A (BFA), ionomycin (ionomycin). The levels of IFN- 緯 and TNF- 偽 were detected by flow cytometry. The relationship between each index and hepatitis B virus load and serum alanine aminotransferase was analyzed by independent sample t test and Pearson correlation analysis. Results compared with the normal control group, the proportion of NK cells and NKT cells in peripheral blood of CHB patients was significantly decreased, NKG2A positive NK cells and NKT cells were significantly increased, and IFN- 緯 positive NK cells and NKT cells were significantly decreased after PMA,BFA,ionomycin stimulation. Conclusion there are some functional disorders such as the decrease of NK,NKT cells, the imbalance of receptor expression and the decrease of cytokine secretion in CHB patients.
