The glutaminase-dependent acid resistance system. Qualitative and quantitative assays and analysis of its distribution in enteric bacteria [PDF]

open access: yes, 2018
Neutralophilic bacteria have developed several strategies to overcome the deleterious effects of acid stress. In particular, the amino acid-dependent systems are widespread, with their activities overlapping, covering a rather large pH range, from 6 to

Calcitonin Gene‐Related Peptide (CGRP)‐Expressing Neurons in the External Lateral Parabrachial Area Regulate Pain‐Induced Sleep Disturbances

open access: yesAdvanced Science, EarlyView.
Lynch et al., identified novel targets on the wake‐promoting pathways that can effectively treat pain‐induced sleep disturbances. The authors demonstrated that Calcitonin gene‐related peptide‐expressing neurons (CGRP) in the external lateral parabrachial nucleus (PBelCGRP) serve as the primary relay node for pain stimuli that cause sleep disruption ...

Auxin‐Producing Pseudomonas Recruited by Root Flavonoids Increases Rice Rhizosheath Formation through the Bacterial Histidine Kinase Under Soil Drying

open access: yesAdvanced Science, EarlyView.
Drought is a major cause of crop losses across agricultural regions. Rhizosheath formation enhances plant resistance to drought. Polyploids may tolerate stress more effectively through increased interactions with bacteria. However, the contributions of tetraploid rice associated microbiota to rhizosheath formation under soil drying remain unclear ...

Activation of Kir4.1 Channels by 2‐D08 Promotes Myelin Repair in Multiple Sclerosis

open access: yesAdvanced Science, EarlyView.
Multiple sclerosis causes myelin loss and neurological dysfunction. This study shows that 2‐D08, a small molecule targeting Kir4.1 channels, promotes OPCs differentiation via FYN tyrosine kinase phosphorylation and the FYN/MYRF pathway. It significantly improves myelin repair and motor deficits in EAE mice and marmosets, highlighting its potential as a

Long Term High‐Salt Diet Induces Cognitive Impairments via Down‐Regulating SHANK1

open access: yesAdvanced Science, EarlyView.
The study identifies a novel mechanistic link between long‐term HS diet and cognitive impairment, wherein PKA/CREB axis inactivation leads to SHANK1 reduction, synaptic damage, and cognitive deficits. Abstract High‐salt (HS) diet is an established risk factor for cognitive impairment, but the underlying mechanisms remain unclear.

Construction of Trans-4-hydroxy-L-proline-producing Escherichia coli and Optimization of Fermentation Conditions

open access: yesFermentation
In this study, we combined the citric acid cycle with the biosynthesis pathways of L-proline and L-hydroxyproline to construct a strain that produces L-hydroxyproline directly from glucose and other raw materials, without the addition of L-proline and α ...

Bionic Nanostructures Create Mechanical Signals to Mediate the Composite Structural Bone Regeneration Through Multi‐System Regulation

open access: yesAdvanced Science, EarlyView.
Inspired by the structural and functional characteristics of bone, bionic nanomaterials combined with nanotechnology can more accurately replicate stem cell niches, enabling the design of bone tissue engineering scaffolds with diverse nanoscale properties to promote stem cell migration, proliferation, and differentiation. This precise control over stem

Evidence for glutamate-mediated excitotoxic mechanisms during photoreceptor degeneration in the rd1 mouse retina [PDF]

open access: yes, 2005
PURPOSE: Kinetic studies of photoreceptor cell death in the retinal degeneration (rd1) mouse model suggest that photoreceptor degeneration could result from cumulative damage.
