人类T淋巴细胞表面有异种红细胞受体,例如羊红细胞受体(简称SRBC受体),当它与绵羊红细胞(SRBC)接触后,能形成E玫瑰花结,E玫瑰花在一定程度上可以反映人体细胞免疫的功能状态。目前临床上已广泛地用作非特异性细胞免疫的指标之一,但对此受体的性质还不十分清楚。一般认为 Human T lymphocytes have heterologous erythrocyte receptors, such as sheep erythrocyte receptors (referred to as SRBC receptors) on the surface of human T lymphocytes. When contacted with sheep erythrocytes (SRBC), human erythrocytes (EBCs) can form E rosette, which to some extent can reflect Functional status of human cellular immunity. Currently, it has been widely used as one of the indicators of nonspecific cellular immunity clinically, but the nature of this receptor is not yet clear. Generally considered
