Background: Alcohol use disorder (AUD) has been associated with Alzheimer's disease (AD) and dementia, yet the underlying mechanisms and specific role of ethanol in AD progression remain poorly understood. Neuroinflammation has emerged as a key contributor to both AD pathogenesis and ethanol-induced brain damage. Activation of innate immune cells and signaling pathways, in particular NLRP3 inflammasome, plays a pivotal role in both AD and ethanol-induced inflammation.

Globally, deep vein thrombosis (DVT) is one of the major preventable causes of mortality and morbidity. Due to the paucity of objective clinical examination findings and non-specific subjective complaints, optimal modalities for the diagnosis of DVT remain unclear. Two adhesion molecules that are engaged in thrombus formation and inflammation, P- and E-selectins, have shown a potential to serve as excellent biomarkers for the early detection of DVT.

Many patients with chronic obstructive pulmonary disease are susceptible to recurrent exacerbations. In this study, we hypothesized that endogenous acetylcholine (ACh) may act as a proinflammatory mediator because long-acting muscarinic receptor antagonists protect against exacerbations, which have an inflammatory basis. This possibility was explored by determining if carbachol (CCh), a stable ACh analog, was a genomic stimulus in BEAS-2B bronchial epithelial cells.

The pathological role of interferon signaling is emerging in neuroinflammatory disorders, yet, the specific role of Interferon Regulatory Factor 3 (IRF3) in neuroinflammation remains poorly understood. Here, we show that global IRF3 deficiency delays TLR4-mediated signaling in microglia and attenuates the hallmark features of LPS-induced inflammation such as cytokine release, microglial reactivity, astrocyte activation, myeloid cell infiltration, and inflammasome activation. Moreover, expression of a constitutively active IRF3 (S388D/S390D: IRF3-2D) in microglia induces a transcriptional program reminiscent of the Activated Response Microglia and the expression of genes associated with Alzheimer's disease, notably apolipoprotein-e.

Article Synopsis
  • Severe alcohol-associated hepatitis (AH) is a serious liver disease characterized by increased neutrophil infiltration, but the impact of alcohol on neutrophil function is still not fully understood.
  • Researchers discovered that Bruton's tyrosine kinase (BTK) is elevated in neutrophils of AH patients and is activated by alcohol through TLR4 signaling, linked to liver damage.
  • In mouse models, inhibiting BTK or knocking it out in specific immune cells reduced neutrophil activity and damage to the liver, suggesting that targeting BTK and its interaction with CD84 might offer new treatments for AH.

It has been proposed that inhaled E-prostanoid 4 (EP)-receptor agonists could represent a new class of bronchodilators for the treatment of asthma that are as effective as -adrenoceptor agonists. However, the genomic impact of such drugs is unknown despite being potentially deleterious to respiratory health. Herein, we used mRNA-seq to compare the transcriptomic responses produced by 2-[3-[(1R,2S,3R)-3-hydroxy-2-[(E,3S)-3-hydroxy-5-[2-(methoxymethyl)phenyl]pent-1-enyl]-5-oxo-cyclopentyl]sulphanylpropylsulphanyl] acetic acid (ONO-AE1-329; an EP-receptor agonist) and vilanterol (a -adrenoceptor agonist) in BEAS-2B human airway epithelial cells.

Article Synopsis
  • Chronic liver injury from cholestasis leads to significant tissue damage, fibrosis, and kidney complications; IRF3 plays a key role in regulating inflammation and cell death in this process.
  • In studies with patients and mice models of cholestasis, increased phosphorylation of IRF3 was linked to higher tissue damage in the liver and kidneys, while IRF3 knockout mice showed reduced damage and inflammation.
  • The study highlights a potential mechanism where bile acids activate IRF3, which then upregulates ZBP1, suggesting that the IRF3-ZBP1 pathway could be crucial in understanding and addressing cholestatic liver and kidney injuries.

Atoms confined in optical tweezer arrays constitute a platform for the implementation of quantum computers and simulators. State-dependent operations are realized by exploiting electrostatic dipolar interactions that emerge, when two atoms are simultaneously excited to high-lying electronic states, so-called Rydberg states. These interactions also lead to state-dependent mechanical forces, which couple the electronic dynamics of the atoms to their vibrational motion.

Background And Purpose: It has been proposed that genomic mechanisms contribute to adverse effects often experienced by asthmatic subjects who take regular, inhaled β -adrenoceptor agonists as a monotherapy. Moreover, data from preclinical models of asthma suggest that these gene expression changes are mediated by β-arrestin-2 rather than PKA. Herein, we tested this hypothesis by comparing the genomic effects of formoterol, a β -adrenoceptor agonist, with forskolin in human primary bronchial epithelial cells (HBEC).

Ambient temperature varies constantly. However, the period of circadian pacemakers is remarkably stable over a wide-range of ecologically- and physiologically-relevant temperatures, even though the kinetics of most biochemical reactions accelerates as temperature rises. This thermal buffering phenomenon, called temperature compensation, is a critical feature of circadian rhythms, but how it is achieved remains elusive.

Chronic use of -adrenoceptor agonists as a monotherapy in asthma is associated with a loss of disease control and an increased risk of mortality. Herein, we tested the hypothesis that -adrenoceptor agonists, including formoterol, biased, -arrestin (Arr) 2-dependent activation of the mitogen-activated protein kinases, ERK1/2, in human airway epithelial cells and, thereby, effect changes in gene expression that could contribute to their adverse clinical outcomes. Three airway epithelial cell models were used: the BEAS-2B cell line, human primary bronchial epithelial cells (HBEC) grown in submersion culture, and HBEC that were highly differentiated at an air-liquid interface.
