The CD66 (CEA) family proteins (specifically CD66a, c, d, and e) have recently been reported to function as the receptors which the bacterial species Neisseria gonorrhoeae and Neisseria meningitidis use to mediate adherence to and cellular invasion of endothelia, epithelia and granulocytic cells (Virji et al. 1996; Chen and Gotschlich 1996; Gray-Owen et al. 1997). The differential specificity of distinct phase-variable Opa proteins expressed by these bacteria for individual CD66 members influences both tissue interactions and cellular response to bacterial binding via these receptors (Gray-Owen et al. 1997, in press).
