Pseudomonas aeruginosa Type IV pilus and resistance to the antimicrobial properties of surfactant protein-A
The lung contains numerous innate immune cells and effector proteins. One important component of this immune system is the surfactant protein-A (SP-A), which facilitates microbial clearance by opsonization and membrane permeabilization. Pseudomonas aeruginosa (PA) is a major Gram-negative bacterial …
