概要 | The fimbriae of Porphyromonas gingivalis mediate critical roles in host colonization and evasion of innate defenses and comprise polymerized fimbrilin (FimA) associated with accessory proteins (FimCDE) of unknown function. We now show that P. gingivalis fimbriae lacking FimCDE fail to interact with the CXCR4. Purified FimC and FimD (but not FimE) were shown to interact with CXCR4. In addition, FimC and FimD bound to fibronectin and type 1 collagen, whereas FimE failed to interact with these matrix proteins. These data and the fact that FimE is required for the association of FimCDE with P. gingivalis fimbriae suggest that FimE may recruit FimC and FimD into a functional complex. Consistent with this notion, FimE was shown to bind both FimC and FimD. In summary, the FimCDE components cooperate and impart critical adhesive and virulence properties to P. gingivalis fimbriae. |
