Directional information flow in human frataxin defines allosteric pathways connecting the hydrophobic core to the iron‐binding ridge

The FEBS Journal, EarlyView.
Human frataxin deficiency causes Friedreich's ataxia, yet how iron‐binding events are communicated across the protein is unclear. Using transfer entropy analysis of molecular dynamics simulations, we identify buried hydrophobic core leucines (LEU136, LEU140) as the source of directional signaling toward the iron‐binding acidic ridge.

Energetic dysregulations in psychotic disorders: Targets for new therapeutics

The FEBS Journal, EarlyView.
The present review synthesizes literature documenting aberrant energy production and use, specifically related to mitochondrial and redox dysregulation, in psychotic disorders. Findings from different levels of investigation—genetic, cellular, and in vivo imaging—converge on aberrant energy metabolism as a hallmark of psychotic disorders.

4‐1BBL Suppresses Anti‐Inflammatory Responses by Regulating Metabolic Reprogramming of Macrophages

Immunology, EarlyView.
4‐1BB ligand (4‐1BBL) is known to promote sustained pro‐inflammatory responses in macrophages. This study demonstrates that 4‐1BBL acts as a negative regulator of anti‐inflammatory macrophage responses. Genetic deletion or pharmacological inhibition of 4‐1BBL significantly enhanced the phosphorylation of IL‐4R‐proximal JAK1 and STAT6, elevating the ...

Metabolic Profiling of Circulating and Tumour‐Infiltrating T Cells Uncovers Bioenergetic Checkpoints Linked With Immune and Clinical Skewing in Melanoma Patients

Immunology, EarlyView.
In this study, we revealed the disturbed metabolic status of circulating and tumour‐infiltrating CD4+ and CD8+ T cells in melanoma patients through targeted metabolomic and lipidomic (on sorted subsets) and at single cell level using the SCENITH method.

Linoleic Acid Enhances Murine Natural Killer Cell Function In Vitro but Compromises Mitochondrial Bioenergetic Function During Retroviral Infection

Immunology, EarlyView.
Natural Killer (NK) cells are potent effectors against virus‐infected and tumour cells. During Friend Virus (FV) infection, fatty acid metabolism supports NK‐cell effector functions. Here, we found that NK cells from FV‐infected mice preferentially take up linoleic acid (LA), which reduced proliferation, mitochondrial function, and increased reactive ...

Trypanosomal MICOS Is Assembled on Non‐Respiring Mitochondrial Crista Precursors and Associates With Two Integral Microproteins

Molecular Microbiology, EarlyView.
The mitochondrial membrane‐shaping machinery MICOS is assembled surprisingly early during the life cycle of Trypanosoma brucei, before the mitochondrion acquires its mature architecture or full respiratory capacity. Our study also identifies two previously uncharacterized proteins associated with MICOS, providing new insight into the early organization

Transcriptome Analysis Reveals Distinct Molecular Signatures Between Erosive and Non‐Erosive Oral Lichen Planus

Oral Diseases, EarlyView.
ABSTRACT Objectives To identify molecular mechanisms distinguishing the erosive subtype of oral lichen planus (EOLP) from the non‐erosive subtype (NEOLP) through transcriptomic analysis. Methods We analysed bulk RNA‐seq data from 30 buccal mucosa samples (13 EOLP, 17 NEOLP) using differential expression, Gene Set Enrichment Analysis (GSEA ...

Mapping the Bioenergetic Landscape of Oral Cancer Stem Cells: A Systematic Review

Oral Diseases, EarlyView.
ABSTRACT Objectives Oral squamous cell carcinoma (OSSC) remains highly lethal, with resistance largely driven by cancer stem cells (CSCs). Mitochondrial reprogramming supports CSC redox control, self‐renewal, and survival. This systematic review aimed to synthesize mitochondrial mechanisms sustaining CSCs in OSCC and evaluate their therapeutic ...

Understanding exosomes in regenerative dentistry

Periodontology 2000, EarlyView.
Abstract Background Regenerative dentistry is shifting from cell‐based strategies to cell‐free biologics capable of orchestrating intricate tissue repair. Exosomes, nanosized extracellular vesicles carrying bioactive molecular payloads, have emerged as central modulators of intercellular communication.

Understanding Exosomes in Hair Regeneration

Periodontology 2000, EarlyView.
Abstract Background Alopecia is a prevalent condition correlated with significant psychosocial challenges, while contemporary treatments exhibit variable efficacy, require extended use, and may cause adverse effects. This review aimed to comprehensively assess exosome‐mediated interventions as a novel cell‐free regenerative approach for hair ...
