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.
