CD 5和CD 6都是淋巴细胞表面糖蛋白,似乎在T细胞活化中起作用。在人类中,CD 6是一种105000/130000 Mr的单体,由外周血T细胞和髓质胸腺细胞以及一小部分外周血B细胞高水平表达(Kamoun等人,1981年; Reinherz等人,1982 a,B; Morimoto等人,1988年; Endres等人,1989年; Swack等人,1989年; Cardenas等人,1990年; Aruffo等人,1991年; Swack等人,1991年)。小鼠同源物最近被证明是在淋巴结和脾脏中的胸腺细胞和T细胞表面上表达的130000 Mr糖蛋白(罗宾逊et al. 1995)。单克隆抗体(mAb)交联研究表明,CD 6连接与辅助细胞、PMA或抗CD 2/CD 3 mAb提供的共刺激信号组合可诱导人T细胞增殖(步行者等人,1987; Morimoto等人,1988; Gangemi等人,1989; Swack等人,1989; Bott等人,1993; Osorio等,1994). CD 5是一种67000 Mr的单体糖蛋白,在所有成熟T细胞、大多数胸腺细胞和一部分成熟B细胞上表达(Ledbetter等,1980; Wang等,1980; Caligamin-Cappio等,1982; Hayakawa等,1985; Jones等,1986; Huang等,1987 a)。与CD 6一样,CD 5似乎也在人和小鼠的T细胞活化中起重要作用,因为通过mAb交联CD 5以单核细胞依赖性方式或响应于促分裂原、同种异体抗原或CD 3特异性mAb而增强T细胞增殖(霍兰德等人,1981; Ledbetter等人,1985; Ceuppens和Baroja,1986; Nishimura等人,1988; Spertini et al. 1991; Vandenberghe and Ceuppens 1991; Alberola-Ila et al.
CD5 and CD6 are both lymphocyte cell surface glycoproteins that appear to play a role in T-cell activation. In humans, CD6 is a 105000/130000 Mr monomer expressed at high levels by peripheral blood T cells and medullary thymocytes, and also by a small fraction of peripheral blood B cells (Kamoun et al. 1981; Reinherz et al. 1982a, b; Morimoto et al. 1988; Endres et al. 1989; Swack et al. 1989; Cardenas et al. 1990; Aruffo et al. 1991; Swack et al. 1991). The mouse homologue has recently been shown to be a 130000 Mr glycoprotein expressed on the surface of thymocytes and T cells in lymph node and spleen (Robinson et al. 1995). Monoclonal antibody (mAb) crosslinking studies have shown that CD6 ligation in combination with costimulatory signals provided by accessory cells, PMA or anti-CD2/CD3 mAbs can induce proliferation of human T cells (Walker et al. 1987; Morimoto et al. 1988; Gangemi et al. 1989; Swack et al. 1989; Bott et al. 1993; Osorio et al. 1994).CD5 is a 67000 Mr monomeric glycoprotein expressed on all mature T cells, most thymocytes, and a subset of mature B cells (Ledbetter et al. 1980; Wang et al. 1980; Caligaris-Cappio et al. 1982; Hayakawa et al. 1985; Jones et al. 1986; Huang et al. 1987 a). Like CD6, CD5 also seems to play an important role in T-cell activation both in humans and mice, as crosslinking of CD5 by mAbs enhances T-cell proliferation either in a monocyte-dependent manner or in response to mitogens, alloantigens, or CD3-specific mAbs (Hollander et al. 1981; Ledbetter et al. 1985; Ceuppens and Baroja 1986; Nishimura et al. 1988; Spertini et al. 1991; Vandenberghe and Ceuppens 1991; Alberola-Ila et al.
