  • Title: Lipopolysaccharide binding protein-deficient mice have a normal defense against pulmonary mycobacterial infection.
    Author: Branger J, Leemans JC, Florquin S, Speelman P, Golenbock DT, van der Poll T.
    Journal: Clin Immunol; 2005 Aug; 116(2):174-81. PubMed ID: 15993364.
    Abstract:
    Lipopolysaccharide (LPS) binding protein (LBP) facilitates the transfer of LPS of Gram-negative bacteria to the pattern recognition receptor CD14, resulting in activation of immunocompetent cells. LBP can also facilitate the binding of lipoarabinomannan, a major cell wall component of mycobacteria, to immune cells. To determine the role of LBP in the immune response to pulmonary Mycobacterium tuberculosis infection, LBP gene-deficient (-/-) and normal wild-type (WT) mice were intranasally infected with M. tuberculosis. LBP-/- mice displayed a similar survival and mycobacterial outgrowth in lungs and liver, although they demonstrated a reduced lymphocyte recruitment and activation during the early stages of infection. The clearance of pulmonary infection with the non-pathogenic M. smegmatis was also unaltered in LBP-/- mice. These data suggest that LBP does not contribute to an effective host response in M. tuberculosis infection.
