CD11b limits bacterial outgrowth and dissemination during murine pneumococcal pneumonia.


Expression of CD11b is enhanced on neutrophils recruited to the lungs during bacterial pneumonia. To determine the role that CD11b plays in pneumonia, CD11b gene-deficient (CD11b(-/-)) mice and normal wild-type (wt) mice were intranasally infected with Streptococcus pneumoniae. CD11b(-/-) mice had an enhanced outgrowth of pneumococci in the lungs and an… (More)
