CD27, a member of the nerve growth factor receptor (NGFR) superfamily, is a type I transmembrane protein consisting of a disulphide-linked 120 kDa homodimer (Bigler, 1988; Sugita, 1992; Morimoto, 1995). CD27 is expressed on mature thymocytes and on the majority of human peripheral blood T cells, on both CD4+ and CD8+ subsets. CD27 is also expressed on activated B cells and a fraction of resting natural killer (NK) cells (Maurer, 1990; Sugita, 1992). Among CD4+ T cells, CD27 is preferentially expressed on unprimed CD4+CD45RA+CD45R0- T cells, while primed CD4+CD45RA-CD45R0+ T cells express low levels of CD27 (Sugita, 1992). During activation, the expression of CD27 is increased on B cells and unprimed T cells, while primed T cells have a relatively low capacity for upregulation of CD27 (Morimoto, 1995; Hintzen, 1994). The activation is also accompanied by the appearance of a 32 kDa soluble form of CD27 (sCD27) found in supernatants of activated lymphocytes (Hintzen, 1994).
CD27 is believed to play a role in T cell activation, since the expression is upregulated during T cell activation (Bigler, 1988; Sugita, 1992; Morimoto, 1995; Maurer, 1990; Hintzen, 1994; Lens, 1995).
