Function | LecB is a fucose-/mannose-specific lectin. It may help in the adhesion of P. aeruginosa cells to the receptors and facilitate biofilm formation resulting in host tissue colonization. This virulence factor has an important role in human infection. It inhibits the ciliary beating and hence defence mechanism of the lung. It is involved in cystic fibrosis. |
