D 细胞(Double Cell)是一小群同时具有 T 细胞表面标志(能与绵羊红细胞形成玫瑰花结)和 B 细胞表面标志(或具有膜表面 Ig,或具有 Ig 的 F_C 受体,或具有 C_3受体)的双重标志淋巴细胞,其功能尚不清楚,用肥大细胞瘤免疫小鼠后,小鼠脾中的 D 细胞能杀伤这些瘤细胞,故认为 D 细胞可能是一种细胞毒性细胞。本实验以羊红细胞作为检测 T 细胞受体的指示细胞,以及以抗鸡红细胞抗体致敏的
D Cell (Double Cell) is a small group of cells that have both a T cell surface marker (rosetting with sheep erythrocytes) and a B cell surface marker (either with membrane surface Ig, or F_C receptor with Ig, or with C_3 receptor Body) dual-labeled lymphocytes, its function is not clear, with mast cell immunization of mice, the mouse spleen D cells can kill these tumor cells, so that D cells may be a cytotoxic cells. In this experiment, sheep red blood cells as a detection of T cell receptor indicator cells, and anti-chicken erythrocyte antibody sensitized
