Reduced transient receptor potential vanilloid 2 expression in alveolar macrophages causes COPD in mice through impaired phagocytic activity

BMC Pulmonary Medicine, 2019
Background Defective phagocytosis in alveolar macrophages is associated with chronic obstructive pulmonary disease (COPD). Transient receptor potential cation channel subfamily V member 2 (TRPV2), a type of nonselective cation channel pertinent to ...

A novel alveolar Krebs cycle-triggered CO2 sensing mechanism regulates regional pulmonary ventilation. [PDF]

, 2011
Pulmonary perfusion disorders provoke atelectasis in order to minimize ventilation/perfusion mismatch. However, the underlying mechanisms remain unknown.

Histone deacetylase 2 is phosphorylated, ubiquitinated, and degraded by cigarette smoke [PDF]

, 2009
Cigarette smoke (CS)-induced lung inflammation involves the reduction of histone deacetylase 2 (HDAC2) abundance, which is associated with steroid resistance in patients with chronic obstructive pulmonary disease and in individuals with severe asthma who

Targeted β‐Glucan‐Veiled Oral Apremilast Nanotherapy Modulates Key Dysbiosis‐Associated Gut Microbiota and Alleviates Ulcerative Colitis‐Associated Anxiety, Depression, and Neuropsychiatric Behaviors

Advanced Science, EarlyView.
This study introduces β‐glucan‐shielded apremilast laden nanomicelles that withstand gastrointestinal degradation, selectively accumulate in inflamed colon tissue, and modulate the microbiota–gut–brain axis. The formulation restores barrier integrity, reduces systemic and neuroinflammation, and improves anxiety‐ and depression‐like behaviors in colitis

PEAR1 Promotes Glucose Metabolism Reprogramming in Sepsis‐Associated Acute Lung Injury via AARS1‐Mediated HIF‐1α Lactylation

Advanced Science, EarlyView.
This study revealed that a PEAR1/HIF‐1α/ glycolysis/lactate/H3K18la positive feedback loop in PMVECs that drives the development of S‐ALI. Mechanistically, PEAR1 mediates the binding of HIF‐1α to AARS1, leading to the lactylation of HIF‐1α, the primary lactylation site of which is K172.

CD4+ T-cell independent secondary immune responses to Pneumocystis pneumonia

Frontiers in Immunology, 2016
Pneumocystis pneumonia is a major cause of morbidity and mortality among immunocompromised patients, especially in the context of HIV/AIDS. In the murine model of Pneumocystis pneumonia, CD4+ T-cells are required for clearance of a primary infection of ...

Pro-inflammatory effects of e-cigarette vapour condensate on human alveolar macrophages

Thorax, 2018
Objective Vaping may increase the cytotoxic effects of e-cigarette liquid (ECL). We compared the effect of unvaped ECL to e-cigarette vapour condensate (ECVC) on alveolar macrophage (AM) function. Methods AMs were treated with ECVC and nicotine-free ECVC

Uptake of nanoparticles by alveolar macrophages is triggered by surfactant protein A

, 2011
From the clinical editor: In this nano-toxicology study of inhaled nanoparticles, the authors investigated the effect of pulmonary surfactant protein A on the interaction between nanoparticles and alveolar macrophages utilizing magnetite nanoparticles ...

Enhancing Super‐Resolution Spatial Transcriptomics Data by Transfer Learning

Advanced Science, EarlyView.
SpotZoomer employs a transfer‐learning‐based strategy to enhance the resolution of Visium data by leveraging available high‐resolution priors. The resulting super‐resolved maps enable sharper delineation of cell boundaries and more precise inference of cell–cell communication patterns that would otherwise remain obscured at native resolution.

Alveolar macrophages are critical for broadly-reactive antibody-mediated protection against influenza A virus in mice

Nature Communications, 2017
The aim of candidate universal influenza vaccines is to provide broad protection against influenza A and B viruses. Studies have demonstrated that broadly reactive antibodies require Fc–Fc gamma receptor interactions for optimal protection; however, the ...
