LAG‐3+ Regulatory T Cells Suppress Effector Function of T Cells and Allow Their Proliferation Into Regulatory T Cells

open access: yesImmunology, EarlyView.
LAG‐3+ regulatory T cells suppress the effector but not the proliferative response of naïve cognate antigen‐specific CD4+ T cells in vivo. The suppressed T cells display upregulation of immune checkpoints and downregulation of pro‐inflammatory pathways with enhanced TCR signaling and reduced oxidative metabolism.

The key mechanisms associated with the survival of Gulf toadfish, Opsanus beta, when in severe hypoxia

open access: yesJournal of Fish Biology, EarlyView.
Abstract Florida's shallow seagrass beds experience daily diurnal fluctuations in environmental oxygen, leading to hypoxic episodes (PO2 < 2 mg L−1, ~6 kPa) that have increased in frequency and intensity in recent decades. The native Gulf toadfish (Opsanus beta) have been shown to employ a suite of adaptive cardiovascular, ventilatory and metabolic ...

Systemic, Lifestyle and Environmental Modifying Factors in the Pathogenesis of Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
A variety of impacting factors in the pathogenesis of periodontitis exist, including systemic, lifestyle, and environmental factors. This review highlights the manifold mechanistic aspects of the link between the pathogenesis of periodontitis, addressing these numerous factors to supplement the long‐standing knowledge of the progression of the disease.

Alkaline pH-Driven Metabolic Plasticity of Lactococcus lactis FM03. [PDF]

open access: yesEnviron Microbiol
Alkaline pH induces a metabolic shift in Lactococcus lactis FM03 from mixed‐acid to homolactic fermentation, driven by proteome‐level constraints in the mixed‐acid branch. This shift reduces biomass yield despite unchanged bioenergetics. Moreover, alkaline pH changes cell morphology and prevents elongation at higher growth rates.

Whole‐Genome Sequencing and Phenotyping Reveal Specific Adaptations of Lachancea thermotolerans to the Winemaking Environment

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Adaptation to the environment plays an essential role in yeast evolution as a consequence of selective pressures. Lachancea thermotolerans, a yeast related to fermentation and one of the current trends in wine technology research, has undergone an anthropisation process, leading to a notable genomic and phenomic differentiation.

The Gfr Uptake System Provides a Context‐Dependent Fitness Advantage to Salmonella Typhimurium SL1344 During the Initial Gut Colonization Phase

open access: yesMolecular Microbiology, EarlyView.
Diet–microbiota interactions shape colonization resistance. While the microbiota restricts pathogens like Salmonella through nutrient competition, Salmonella can exploit private nutrients such as fructoselysine (FL), abundant in processed foods but inaccessible to most microbes.

Enhanced O2 availability in platelet concentrates stored for neonatal transfusion is independent of agitation: Evidence from direct oximetry and Fickian diffusion modelling

open access: yesVox Sanguinis, EarlyView.
Abstract Background and Objectives Platelet transfusions are essential for mitigating the bleeding risk of neonatal patients with thrombocytopenia. As neonatal patients have a small blood volume, adult therapeutic dose platelet units are split into reduced‐volume storage containers to maximize the use of the donated product and reduce donor exposure ...

Effects of short‐term exercise on plasma metabolic and lipidomic profiles of individuals with type 2 diabetes

open access: yesExperimental Physiology, EarlyView.
Abstract Type 2 diabetes mellitus (T2DM) is a common metabolic disorder characterized by chronic hyperglycaemia, with physical inactivity and excessive adiposity as predisposing factors. This clinical trial aimed to investigate the effects of an exercise intervention on the metabolome of T2DM participants, fasting and in response to an oral glucose ...
