Administration of multilamellar vesicles (MLV) encapsulating a synthetic peptide (RS-83277) derived from human C-reactive protein (CRP) augments anti-tumor activity of murine alveolar macrophages and reduces established pulmonary metastases of experimental tumors. To explore mechanisms involved in these phenomena, we investigated cytokine and integrin (CDllb) expression of bronchoalveolar lavag...

The word ‘‘Obstructive’’ is misspelled in the article title. The correct title is: Increased Iron Sequestration in Alveolar Macrophages in Chronic Obstructive Pulmonary Disease. The correct citation is: Philippot Q, Deslée G, Adair-Kirk TL, Woods JC, Byers D, et al. (2014) Increased Iron Sequestration in Alveolar Macrophages in Chronic Obstructive Pulmonary Disease.

Pulmonary macrophages consist of several subpopulations that can be defined by their anatomical locations as well as by other criteria. In addition to the well-known alveolar macrophages that reside on the alveolar surface, pulmonary macrophages also occur in the conducting airways, in various pulmonary interstitial regions, and, in some mammalian species, in the lung's intravascular compartmen...

Exposure of rabbit alveolar and peritoneal macrophages to infectious herpes simplex virus resulted in inhibition of antibody-dependent cellular cytotoxicity and either enhancement or inhibition of phagocytosis. At all times after exposure, virus was inhibitory to peritoneal macrophage phagocytosis. Alveolar macrophages showed enhanced phagocytic activity in the early stages of virus exposure an...

Fibrin deposition is prominent in the histopathology of a number of inflammatory lung diseases. Plasmin, activated locally in the lung, can degrade not only this fibrin but potentially structural proteins important to normal lung architecture. Because alveolar macrophages are prominent in inflammatory processes of the lung, we examined the plasminogen activator (PA) activity of human alveolar m...
