摘要:

目的    探讨鼻咽癌组织中VEGF表达与树突状细胞含量的相关性。方法    选取鼻咽癌组织和鼻咽部淋巴组织各25例,采用ELISA方法检测组织中VEGF的表达,采用流式细胞仪检测组织中树突状细胞和调节性T细胞的含量并分析其相关性。结果    鼻咽癌组织中VEGF含量高于鼻咽部淋巴组织,组间差异具有统计学意义(t=12.324,P<0.01);鼻咽癌组织中CD4+淋巴细胞含量低于鼻咽部淋巴组织,组间差异具有统计学意义(t=14.304,P<0.01);而鼻咽癌组织中CD4+CD25+调节性T淋巴细胞含量高于鼻咽部淋巴组织,组间差异具有统计学意义(t=5.910,P<0.01);鼻咽癌组织中CD123+树突状细胞含量低于鼻咽部淋巴组织,组间差异具有统计学意义(t=7.866,P<0.01),鼻咽癌组织中CD11c+树突状细胞含量低于鼻咽部淋巴组织,组间差异具有统计学意义(t=3.411,P<0.01),鼻咽癌组织VEGF表达与CD4+CD25+淋巴细胞含量呈正相关(r=0.966 ,P<0.01),与CD123+树突状细胞含量呈负相关(r= -0.946,P<0.01),与CD11c+树突状细胞含量呈负相关(r= -0.954,P<0.01)。结论    鼻咽癌组织中VEGF表达与鼻咽癌组织中CD4+、CD25+调节性T细胞和树突状细胞的含量有关,可能参与鼻咽癌的免疫逃逸。

Abstract:

Objective    To investigate the correlation between VEGF expression and the content of dendritic cells in nasopharyngeal carcinoma.  Methods    25 cases of nasopharyngeal carcinoma and 25 cases of nasopharyngeal lymphoid tissue were collected. The expressions of VEGF in the nasopharyngeal carcinoma and nasopharyngeal lymphoid tissues were detected by ELISA. The content of dendritic cells and regulatory T cells in the nasopharyngeal carcinoma and nasopharyngeal lymphoid tissues were detected by flow cytometry.  Then the correlation between VEGF expression and the content of dendritic cells was analyzed. Results     Expression of VEGF in nasopharyngeal carcinoma was higher than that in nasopharyngeal lymphoid tissues (t=12.324,P<0.01); the content of CD4+ lymphocyte in nasopharyngeal carcinoma was lower than that in nasopharyngeal lymphoid tissues(t=14.304, P<0.01). While the content of CD4+CD25+ regulatory T cells in nasopharyngeal carcinoma was higher than that in nasopharyngeal lymphoid tissues, and the difference was statistically significant(t=5.910, P<0.01). The content of CD123+ dendritic cells in nasopharyngeal carcinoma was lower than that in nasopharyngeal lymphoid tissues, and the difference was statistically significant(t=7.866, P<0.01). The content of CD11c+ dendritic cells in nasopharyngeal carcinoma was lower than that in nasopharyngeal lymphoid tissues, and the difference was statistically significant(t=3.411, P<0.01). The expression of VEGF was positively correlated with the content of CD4+CD25+ lymphocytes in nasopharyngeal carcinoma(r=0.966, P<0.01), and negatively correlated with the content of CD123+ dendritic cells (r= -0.946, P<0.01) and negatively correlated with the content of CD11c+ dendritic cells(r=-0.954, P<0.01). Conclusion    Expression of VEGF is related to the content of CD4+CD25+ regulatory T cells and the content of dendritic cells in nasopharyngeal carcinoma, which may engage in the immune escape of nasopharyngeal carcinoma.
