Force-Induced Strengthening of the Interaction between Staphylococcus aureus Clumping Factor B and Loricrin
Bacterial pathogens that colonize host surfaces are subjected to physical stresses such as fluid flow and cell surface contacts. How bacteria respond to such mechanical cues is an important yet poorly understood issue. Staphylococcus aureus uses a repertoire of surface proteins to resist shear stress during the colonization of host tissues, but whether their adhesive functions can be modulated ...
متن کاملNasal Colonisation by Staphylococcus aureus Depends upon Clumping Factor B Binding to the Squamous Epithelial Cell Envelope Protein Loricrin
Staphylococcus aureus asymptomatically colonises the anterior nares, but the host and bacterial factors that facilitate colonisation remain incompletely understood. The S. aureus surface protein ClfB has been shown to mediate adherence to squamous epithelial cells in vitro and to promote nasal colonisation in both mice and humans. Here, we demonstrate that the squamous epithelial cell envelope ...

Structural organization of the fibrinogen-binding region of the clumping factor B MSCRAMM of Staphylococcus aureus.
The clumping factor B (ClfB) of Staphylococcus aureus is a surface protein that binds to fibrinogen (Ni Eidhin, D., Perkins, S., Francois, P., Vaudaux, P., Hook, M., and Foster, T. J., 1998 Mol. Microbiol. 30, 245-257). The ligand-binding activity is located in the approximately 500-residue A-region (residues 44-542), which represents the N-terminal half of the MSCRAMM protein. We now hypothesi...
متن کاملImmunogenicity analysis of Staphylococcus aureus clumping factor A genetic variants.
The staphylococcal adhesin clumping factor A (ClfA) has a variant amino acid sequence, generating the potential for alterations in epitope structure and immunogenicity of this vaccine candidate. We demonstrated for two recombinant ClfA(40-531) (a slightly truncated version of the fibrinogen-binding domain of ClfA containing amino acids 40 to 531) genetic variants that strain-specific epitopes a...
