FHA; Filamentous hemagglutinin
The filamentous h?magglutinin adhesin (FHA) is a large, filamentous protein that serves as a dominant attachment factor for adherence to host colliery epithelia cells of the respiratory tract. It is associated with biofilm formation and possesses at least four binding domains which can bind to different cell receptors on the epithelial cell surface. One notable bacterium that possess filamentous h?magglutinin adhesin is Bordetella pertussis, which uses this protein as a virulence factor. Filamentous hemagglutinin (FHA) of Bordetella pertussis is a 220 kDa large adhesive surface protein which together with the pertussis toxin (PTx) facilitates attachment of the bacteria to human ciliated cells and macrophages during the course of whooping cough. FHA can recognize and bind the leukocyte-restricted adhesion molecule suggesting that FHA mimics a natural ligand on endothelial cells for this integrin which enables FHA to competitively interfere with CD18-dependent leukocyte migration to the central nervous system. Anti FHA antibodies have been shown to be able to permeabilize the blood-brain barrier.
