The FGL-1/LAG-3 Axis is Associated With Disease Course in Alcohol-associated Hepatitis: A Preliminary Report.

Background: Alcohol-associated hepatitis (AH) has a short-term mortality rate of up to 40% primarily related to impaired hepatocyte regeneration and uncontrolled liver inflammation. The acute phase protein fibrinogen-like protein 1 (FGL-1) produced by hepatocytes stimulates hepatocyte proliferation by autocrine signaling. FGL-1 also is a ligand for the inhibitory T cell receptor lymphocyte activation gene 3 (LAG-3).

Effect of nicotinamide riboside on airway inflammation in COPD: a randomized, placebo-controlled trial.

Chronic obstructive pulmonary disease (COPD) is a progressive, incurable disease associated with smoking and advanced age, ranking as the third leading cause of death worldwide. DNA damage and loss of the central metabolite nicotinamide adenine dinucleotide (NAD) may contribute to both aging and COPD, presenting a potential avenue for interventions. In this randomized, double-blind, placebo-controlled clinical trial, we treated patients with stable COPD (n = 40) with the NAD precursor nicotinamide riboside (NR) for 6 weeks and followed-up 12 weeks later.

CD21 deficiency in 2 siblings and frequency of the associated mutation in the Danish population.

The clinical presentation of CD21 deficiency in 2 siblings caused by a novel mutation in the CD21 gene is reported, and the frequency of this mutation in the Danish population is explored. Successful treatment with IgG replacement in both patients with CD21 deficiency is also reported.

Climatic forcing and individual heterogeneity in a resident mountain bird: legacy data reveal effects on reproductive strategies.

Optimization of clutch size and timing of reproduction have substantial effects on lifetime reproductive success in vertebrates, and both individual quality and environmental variation may impact life history strategies. We tested hypotheses related to maternal investment and timing of reproduction, using 17 years (1978-1994) of individual-based life history data on willow ptarmigan (, = 290 breeding females with = 319 breeding attempts) in central Norway. We analysed whether climatic variation and individual state variables (age and body mass) affected the number of offspring and timing of reproduction, and individual repeatability in strategies.

Allergen Immunotherapy Enhances Airway Epithelial Antiviral Immunity in Patients with Allergic Asthma (VITAL Study): A Double-Blind Randomized Controlled Trial.

Allergic asthma is linked to impaired bronchial epithelial secretion of IFNs, which may be causally linked to the increased risk of viral exacerbations. We have previously shown that allergen immunotherapy (AIT) effectively reduces asthma exacerbations and prevents respiratory infections requiring antibiotics; however, whether AIT alters antiviral immunity is still unknown. To investigate the effect of house dust mite sublingual AIT (HDM-SLIT) on bronchial epithelial antiviral and inflammatory responses in patients with allergic asthma.
