Hearing modulation affects Alzheimer’s disease progression linked to brain inflammation: a study in mouse models

Molecular Medicine
Background Recent studies have identified hearing loss (HL) as a primary risk factor for Alzheimer’s disease (AD) onset. However, the mechanisms linking HL to AD are not fully understood. This study explored the effects of drug-induced hearing loss (DIHL)

RORγt‐APCs: The New Masters of Oral Tolerance

Barrier Immunity, EarlyView.
ABSTRACT Oral tolerance is defined by the hypo‐responsiveness of our body to fed antigens, and its failure can lead to immune‐mediated diseases, such as allergy, chronic inflammation and autoimmune diseases. Decades of research have demonstrated that antigen‐presenting cells (APCs) promote oral tolerance by inducing regulatory T cells (Tregs) and/or ...

The toxin–antitoxin complex Fic‐1–AntF functions as a deAMPylase that regulates the activity of DNA gyrase

mLife, EarlyView.
Abstract Toxin–antitoxin (TA) systems found in diverse bacteria play important roles in their adaptation to changing environments. The toxin of the Fic‐1–AntF TA pair from Pseudomonas bijieensis strain 2P24 inhibits bacterial DNA replication by attacking the subunit B of DNA gyrase (GyrB) via AMPylation, while the antitoxin AntF blocks its enzymatic ...

The Mycobacterium tuberculosis Rv0132c Gene Product Mtb‐FGD2 Can Act as an F420‐Dependent Glucose Dehydrogenase

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The role of the cell envelope‐associated Rv0132c/FGD2 from Mycobacterium tuberculosis has long been a subject of debate. Importantly, FGD2 is found only in pathogenic mycobacteria, making it a potential drug target. While some suggest it functions as a glucose‐6‐phosphate dehydrogenase, others propose it acts instead as an F420‐dependent ...

Targeting the noncatalytic activity of GSK3β modulates neuronal excitability in medium spiny neurons via Nav1.6 interactions

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Kinases phosphorylate ion channels, but their noncatalytic roles via protein–protein interactions (PPI) are less understood. Here, we identified the peptidomimetic ZL141 to characterize the PPI between GSK3β and Nav1.6, revealing a noncatalytic role for GSK3β in regulating Nav1.6 currents and neuronal excitability ...

Afatinib Overcomes Osimertinib Resistance via Egfr V804F Mutation in a Syngeneic Egfr‐Mutant Lung Cancer Mouse Model

Cancer Science, EarlyView.
Using an immunocompetent mouse model of Egfr Ex19del‐driven lung cancer, we found that osimertinib‐resistant tumors acquired Egfr V804F, the murine counterpart of human EGFR V802F. Afatinib, but not osimertinib, suppressed phosphorylation of EGFR and overcame V804F‐mediated resistance, providing a preclinical rationale for biomarker‐guided therapy ...

A new branch of mammalian vitamin B6 metabolism: AKR1C‐mediated conversion of pyridoxal to pyridoxine and 4‐pyridoxolactone

The FEBS Journal, EarlyView.
Pyridoxal 5′‐phosphate (PLP) homeostasis relies on salvage enzymes, yet key metabolic branches remain undefined. We identify AKR1C isozymes as previously undescribed contributors that convert pyridoxal into pyridoxine or 4‐pyridoxolactone through reductase and dehydrogenase activities.

Human IDO2 exhibits unique binding affinities distinct to those of human IDO1

The FEBS Journal, EarlyView.
Although indoleamine 2,3‐dioxygenase 2 (IDO2) is highly homologous to IDO1, it displays markedly lower catalytic activity. We found that IDO2 binds L‐tryptophan (L‐Trp) in a flipped orientation stabilized by the IDO2‐specific residue His143. Replacement of His143 with the IDO1‐equivalent tyrosine restored an IDO1‐like binding mode and increased ...

Inducing Antigen‐Specific and Functional Immune Responses in Mice Toward Bovine Herpesvirus 1 and Bovine Respiratory Syncytial Virus by Chimeric Peptides Delivered by Bovine Herpesvirus 4‐Based Vector

Immunology, EarlyView.
Bovine Alphaherpesvirus 1 (BoHV‐1) and Bovine respiratory syncytial virus (BRSV) are major drivers of respiratory disease in cattle. (A) To target both pathogens, two chimeric antigens—membrane‐linked and secreted—combining BoHV‐1 glycoprotein D and BRSV fusion glycoprotein were designed and expressed using recombinant BoHV‐4‐based vectors.

FcMAPK4‐phosphorylated FcNOR activates FcERF5 to promote fig fruit softening through activation of FcPG12 expression

Journal of Integrative Plant Biology, EarlyView.
In Ficus carica fruit, the MAP kinase FcMAPK4 phosphorylates the NAC transcription factor FcNOR, which cooperates with ethylene response factor FcERF5 to activate the pectin degradation gene FcPG12, thereby promoting rapid softening of fig fruit. ABSTRACT Rapid softening of fig (Ficus carica L.) fruit during ripening leads to extremely short shelf life;
