ABSTRACT
MALP-2, a synthetic lipopeptide is a Toll-like receptor 2 and -6 ligand and agonist. MALP-2 stimulates immune cells at different sites. Local stimulation in the lungs has beneficial effects in experimental pneumococci infection. The presented study investigated local effects of MALP-2 in the mycobacterial infection of lungs. MALP-2 was applied prior, simultaneously or after the pulmonary infection with Mycobacterium bovis BCG. Colony forming units were determined in the bronchoalveolar lavage fluid and lung homogenate. Numbers of Mycobacterium bovis BCG colony forming units were found to be reduced in two compartments, bronchoalveolar lavage fluid and lung homogenate after treatment with MALP-2 simultaneously to the infection for up to eight weeks. Reduction of the bacterial load in both compartments was also found up to two weeks after local treatment before and after the infection. Thus, macrophage activating lipopeptide-2 enhances the host defence in the lung in acute and long term bacterial infections.
