负有膜受体的淋巴细胞亚群能特异性地与免疫球蛋白Fc段结合。关于负有IgG Fc受体(FcγR)的淋巴细胞已有报道。作者曾报道负有IgE Fc受体的淋巴细胞亚群指出:IgE异常升高的特应性患者,其FcεR~+细胞较非变态反应对照组明显增多,而IgE中度升高、疾病静止期的变态反应患者,FcεR~+淋巴细胞数目和对照组基本相同。为了判断这些患者的FcεR~+淋巴细胞在疾病活动期是否增多,作者们对10名非变态反应对照和7例接受免疫治疗的季节性变应性鼻炎患者在草类花粉季节前、中、后分别采取末梢血作玫瑰花结试验测定负有IgE和IgG Fc受
Lymphocyte subsets with membrane receptors specifically bind to the immunoglobulin Fc segment. Lymphocytes bearing IgG Fc receptors (FcγR) have been reported. The authors report that lymphocyte subsets with IgE Fc receptors indicate that patients with atopic abnormalities in IgE have significantly increased Fc [epsilon] R ~ + cells compared with non-allergic controls, whereas IgE is moderately elevated and disease quiescence Of allergic patients, the number of FcεR ~ + lymphocytes and the control group is basically the same. In order to determine whether these patients increased FcεR ~ + lymphocytes in the disease activity, the authors of 10 non-allergic control and 7 cases of immunocompromised patients with seasonal allergic rhinitis in the grass pollen season before, during and after Peripheral blood was taken for rosette test negative IgE and IgG Fc receptor
