Decreased expression of a phagocytic receptor Siglec-1 on alveolar macrophages in chronic obstructive pulmonary disease

open access: yesRespiratory Research, 2020
Background Alveolar macrophages are professional phagocytes that remove microbial pathogens inhaled into the lung. The phagocytic ability is compromised in chronic obstructive pulmonary disease (COPD).

Alveolar macrophages and the diagnosis of drowning [PDF]

open access: yes, 1993
In the present study, we examined the number of alveolar macrophages in lung tissue from 17 cases of fresh water drowning, 22 cases of acute death and 6 cases of lung emphysema.

Pulmonary giant cells and their significance for the diagnosis of asphyxiation [PDF]

open access: yes, 1993
This study was performed to prove whether the detection of polynuclear giant cells in lungs is useful for the diagnosis of asphyxiation due to throttling or strangulation.

The alveolar macrophage. [PDF]

open access: yesEnvironmental Health Perspectives, 1971
The pulmonary macrophagic system is critical to the defense of the lung, keeping the alveoli clean and sterile and responding on demand with an adaptive outpouring of new cells into the air sacs. Under basal conditions alveolar macrophages, in common with other mononuclear phagocytes, are derived from the bone marrow.

Paraquat promotes acute lung injury in rats by regulating alveolar macrophage polarization through glycolysis

open access: yesEcotoxicology and Environmental Safety, 2021
The present study investigates whether paraquat (PQ) regulates polarization of alveolar macrophages through glycolysis and promotes the occurrence of acute lung injury in rats.

Alveolar macrophages lack CCR2 expression and do not migrate to CCL2

open access: yesJournal of Inflammation, 2007
Background The recruitment of mononuclear cells has important implications for tissue inflammation. Previous studies demonstrated enhanced CCR1 and CCR5 expression and decreased CCR2 expression during in vitro monocyte to macrophage differentiation.

Characterisation of lung macrophage subpopulations in COPD patients and controls

open access: yesScientific Reports, 2017
Lung macrophage subpopulations have been identified based on size. We investigated characteristics of small and large macrophages in the alveolar spaces and lung interstitium of COPD patients and controls.

Disparate oxidant gene expression of airway epithelium compared to alveolar macrophages in smokers

open access: yesRespiratory Research, 2009
Background The small airway epithelium and alveolar macrophages are exposed to oxidants in cigarette smoke leading to epithelial dysfunction and macrophage activation. In this context, we asked: what is the transcriptome of oxidant-related genes in small

IL-1R and inflammasomes mediate early pulmonary protective mechanisms in respiratory brucella abortus infection [PDF]

open access: yes, 2016
Brucella spp. infection is frequently acquired through contaminated aerosols. The role of interleukin-1 beta (IL-1β) in the early pulmonary response to respiratory Brucella infection is unknown.

Cigarette smoking decreases global microRNA expression in human alveolar macrophages. [PDF]

open access: yesPLoS ONE, 2012
Human alveolar macrophages are critical components of the innate immune system. Cigarette smoking-induced changes in alveolar macrophage gene expression are linked to reduced resistance to pulmonary infections and to the development of emphysema/COPD. We
