RESUMO
Candida albicans exhibits examples of human molecular mimicry, including receptors resembling human steroid receptors and human complement receptor (CR)-like receptors that bind the complement fragments C3d and iC3b. To further characterize the epitopes of the Candida human CR-like molecules, a panel of monoclonal antibodies (MAbs) against epitopes within the human CR3 was used. MAbs Mo1, M1/70HL, and 7C3 bound to the germ tube, as assessed by immunofluorescence. MAbs Leu15, 60.1, and 95G8 did not bind. Miscellaneous MAbs against other antigens on human leukocytes (B2, 3D9, and OKT4) did not bind. However, MY9, which recognizes a monocyte antigen, bound extensively to the germ tube. The binding of certain anti-CR3 MAbs suggested limited identity between the Candida CR3-like receptor and the human CR3. The binding of MY9 identified an antigen recognized by a MAb to a human cell antigen not previously known to exist on C. albicans.
