Targeted Delivery of α‐ketoglutarate to Macrophages in Bone: A Novel Therapeutic Strategy for Improving Fracture Healing in Type 2 Diabetes

open access: yesAdvanced Science, EarlyView.
The study reveals that glutaminolysis in macrophages is inhibited under type 2 diabetes mellitus (T2DM) conditions, which impedes fracture healing by reducing bone morphogenetic protein 2 (BMP2) production through increased cytosine methylation on the promoter.

Two Signaling Modes Are Better than One: Flux-Independent Signaling by Ionotropic Glutamate Receptors Is Coming of Age

open access: yesBiomedicines
Glutamate is the major excitatory neurotransmitter in the central nervous system. Glutamatergic transmission can be mediated by ionotropic glutamate receptors (iGluRs), which mediate rapid synaptic depolarization that can be associated with Ca2+ entry ...

Non‐Membrane Active Peptide Resensitizes MRSA to β‐Lactam Antibiotics and Inhibits S. aureus Virulence

open access: yesAdvanced Science, EarlyView.
This work identifies a potent, non‐membrane active, and non‐toxic AMP termed GN1, which substantially resensitizes MRSA to multiple β‐lactam antibiotics at low concentrations. GN1 functions by suppressing MRSA‐associated resistance determinants, including penicillin‐binding protein 2a (PBP2a) and β‐lactamase.

The Lung Microbiome Modulates Pain‐Like Behavior Via the Lung–Brain Axis in a Nitroglycerin‐Induced Chronic Migraine Mouse Model

open access: yesAdvanced Science, EarlyView.
Intratracheal neomycin alters pulmonary microbiota, activating the vagus nerve via lung brain‐derived neurotrophic factor/tropomyosin receptor kinase B (BDNF/TrkB) pathway, further projecting to nucleus of solitary tract (NTS), then dorsal raphe nucleus (DRN), where activated serotoninergic neurons increase brain serotonin, alleviating migraine.

FGF-2 Induces Neuronal Death through Upregulation of System xc- [PDF]

open access: yes, 2014
The cystine/glutamate antiporter (system xc-) transports cystine into cell in exchange for glutamate. Fibroblast growth factor-2 (FGF-2) upregulates system xc- selectively on astrocytes, which leads to increased cystine uptake, the substrate for ...

Müller Glial Cells Participate in Retinal Waves via Glutamate Transporters and AMPA Receptors

open access: yesCell Reports, 2019
Summary: Retinal waves, the spontaneous patterned neural activities propagating among developing retinal ganglion cells (RGCs), instruct the activity-dependent refinement of visuotopic maps. Although it is known that the wave is initiated successively by

Host Plasma Microenvironment in Immunometabolically Impaired HIV Infection Leads to Dysregulated Monocyte Function and Synaptic Transmission Ex Vivo

open access: yesAdvanced Science, EarlyView.
Network‐based risk stratification of people living with HIV (PWH) on prolonged therapy using multi‐omics data identifies 44% of the patients are at risk of immunometabolic complications. A senescence‐associated myeloid cell‐driven plasma microenvironment drives immunometabolic dysregulation in at‐risk PWH.

Tetrandrine alleviates inflammation and neuron apoptosis in experimental traumatic brain injury by regulating the IRE1α/JNK/CHOP signal pathway

open access: yesBrain and Behavior, Volume 12, Issue 12, December 2022., 2022
Abstract Aim The aim of this study was to investigate the therapeutic roles of Tetrandrine (TET) on traumatic brain injury (TBI) and the underlying mechanism. Method Traumatic injury model of hippocampal neurons and TBI mouse model were established to evaluate the therapeutic effects.

Inhibition of Ferroptosis Delays Aging and Extends Healthspan Across Multiple Species

open access: yesAdvanced Science, EarlyView.
This study identifies ferroptosis as a key driver of cellular senescence, with its inhibition delaying aging and extending healthspan across species. During senescence, ferroptosis worsens, increasing oxidative stress and lipid peroxidation, which accelerate aging.
