abstract

  • A subtype of P fimbriae, encoded by the pap-2 gene cluster, has been analyzed for agglutination of erythrocytes and for binding to cryostat sections of the human kidney. We have demonstrated that pap-2-encoded fimbriae are capable of binding to erythrocytes from some animal species and to human erythrocytes which express globoside and the LKE (stage-specific embryonic antigen 4 [SSEA-4]) antigen. The pap-2 fimbriae bind to Bowman's capsule in the human kidney. Monoclonal antibodies directed against glycosphingolipids were used for the detection of specific P blood group-related antigens in the human kidney and on erythrocytes. Preincubation of kidney sections with monoclonal antibody MC813-70, which binds to the SSEA-4 antigen, inhibited adherence of purified pap-2-encoded fimbriae to Bowman's capsule. We suggest that one receptor for pap-2-encoded fimbriae is the antigen known as LKE (Luke) on human erythrocytes or SSEA-4 in the tissues.
