Abstract:Alveolar macrophages are the front-line defense against environmental pathogens. However, to the best of our knowledge, differences in function and phenotypic expression levels of macrophages between neonatal and adult lungs have not previously been determined.

Pulmonary sepsis was induced by intrapleural instillation of lipopolysaccharide (LPS; 20 mg/kg) and survival… Show more
