鼻咽癌免疫抑制因子研究——鼻咽癌细胞培养上清对正常人淋巴细胞cAMP、IL-2及对IL-2增殖活性的影响
在正常人淋巴细胞加入鼻咽癌低分化细胞培养上清(CNE-2S)。分别测定不加入和加入CNE-2S的淋巴细胞内环磷腺苷(cAMP)、白细胞介素-2(IL-2)及对IL-2的增殖活性。绪果,11例正常人淋巴细胞内cAMP含量加入CNE-2S后比未加入前有明显升高(P<0.05)。9例正常人的IL-2活性加入后比未加入前有明显降低(P<0.05)。9例正常人的IL-2受体的增殖活性加入后无显著差异(P>0.05)。结果表明,CNE-2S可提高正常人淋巴细胞内cAMP水平。与此同时,IL-2活性受到明显抑制,但淋巴细胞IL-2受体增殖活性的变化不显著。...
