Influence of depletion of alveolar macrophages on apoptosis in Candida-induced acute lung injury.

Apoptosis plays an important role in acute lung injury (ALI), and alveolar macrophages (AMs) are known to secrete proinflammatory cytokines and promote alveolar inflammation. The authors have previously reported that AMs can be depleted by inhalation of 1 mM 2-chloroadenosine (2-CA). In this study, the authors evaluated the effect of AM depletion by 2-CA inhalation on apoptosis in Candida-induced ALI.
