Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

A two-component cocktail of engineered DIII nanoparticles elicits broadly neutralizing antibody responses against dengue virus in mice

iScience
Summary: Dengue virus (DENV) is a mosquito-transmitted flavivirus; there are four serotypes (DENV1-4) that co-circulate globally. Primary infection causes self-limiting febrile illness, but secondary infection by a heterologous serotype can predispose to

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Regulation of addiction by the insular cortex: The interplay between interoception and cognitive function

iScience
Summary: The insular cortex (IC) functions as a pivotal core for interoception. Functional magnetic resonance imaging reveals how the IC integrates internal and external stimuli by observing its neural activation patterns.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Satellite-based forest structure metrics as a predictive tool for biodiversity in hyperdiverse tropical forests: A test of the habitat heterogeneity hypothesis in the tropics

Environmental and Sustainability Indicators
Tropical forests hold the most species yet face the greatest threats and knowledge gaps. To improve tropical biodiversity knowledge we combined satellite-based LiDAR with in situ bird, mammal, and acoustic soundscape data, via camera and audio recorders,

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Commensal human gut microbes produce species specific neuroactive compounds

iScience
Summary: The gut microbiota communicates with multiple organs through neuroactive molecules, but the specific compounds produced remain unclear. We investigated eight commensal gut species, Lactococcus lactis, Enterococcus faecalis, Blautia producta ...
