Ozone enhances pulmonary innate immune response to a Toll-like receptor-2 agonist.

abstract：:Klebsiella pneumoniae is a common cause of pneumonia. Previous studies have documented an important role for Toll-like receptors (TLRs) expressed by myeloid cells in the recognition of K. pneumoniae and the initiation of a protective immune response. Lung epithelial cells also express TLRs and can participate in innat...
