Vitamin C Transport Deficiency Alters Striatal Dopamine Gene Expression and Metabolism in YAC128 Huntington Disease Mice. [PDF]

Genes Brain Behav
ABSTRACT Neurodegeneration in Huntington disease (HD) contributes to dopaminergic system dysfunction via the loss of striatal medium spiny neurons expressing dopamine receptors. Given the key role for ascorbic acid (vitamin C) in dopamine synthesis and neurotransmission, we investigated whether mild cellular ascorbate deficiency accelerates ...

Vesicle‐Encapsulated Chemosensing Ensembles Allow Monitoring of Transmembrane Uptake Coupled with Enzymatic Reactions

Angewandte Chemie, Volume 137, Issue 13, March 24, 2025.
We have encapsulated a host–guest reporter pair together with three enzymes within vesicles to monitor a two‐compartment cascade reaction which includes transmembrane transport of peptide substrates and their subsequent enzymatic conversion inside the vesicles. Our “protocell” system mimics a simplistic cellular uptake‐metabolism cycle.

When Pathways Converge: Iron, Lipid Peroxidation, and α‐Synuclein in Ferroptosis‐Driven Dopaminergic Neurodegeneration

Journal of Neurochemistry, Volume 170, Issue 4, April 2026.
Dopaminergic neurons are particularly susceptible to ferroptosis. Pacemaking activity–driven calcium (Ca2+) influx increases metabolic demand and reactive oxygen species (ROS) production, promoting iron release from aconitase. Alpha‐synuclein (α‐syn) enhances iron uptake via transferrin receptor 1 (TfR1) and exhibits ferrireductase activity, converting

Hungry for Knowledge: Octopamine Signaling Regulates Hunger‐Enhanced Olfactory Learning

Advanced Science, Volume 13, Issue 12, 27 February 2026.
Researchers demonstrate that hunger state facilitates both aversive and appetitive olfactory learning. Two distinct octopamine signaling pathways are involved in aversive or appetitive memory formation in the hunger state. And, hunger state also facilitates the formation of both types of memories via an evolutionarily conserved norepinephrine (the ...

Astrocyte Regulation of Spinal Circuit Function

Journal of Neurochemistry, Volume 170, Issue 2, February 2026.
Spinal cord astrocytes exist as an additional component of the computational framework that governs both sensory perceptions and motor outputs (left). By integrating local synaptic activity together with signals that reflect whole‐body state (e.g., neuromodulators, immune signals, and vascular signals) into defined input states (Sn), astrocytes adapt ...

Consensus Guideline for the Diagnosis and Treatment of Tyrosine Hydroxylase (TH) Deficiency

Journal of Inherited Metabolic Disease, Volume 48, Issue 6, November 2025.
ABSTRACT Tyrosine hydroxylase (TH) catalyses the rate‐limiting step in dopamine biosynthesis. Autosomal recessive tyrosine hydroxylase deficiency (THD) leads to clinical phenotypes reflecting the deficiency of dopamine, norepinephrine, or epinephrine in the central nervous system (CNS), presenting along a continuous spectrum from mild to severe forms ...

A Focus on Natural Autophagy Modulators as Potential Host‐Directed Weapons Against Emerging and Re‐Emerging Viruses

Medicinal Research Reviews, Volume 45, Issue 6, Page 1850-1882, November 2025.
ABSTRACT Autophagy is a highly conserved intracellular process involved in maintaining homeostasis and in the degradation of damaged organelles and external pathogens. Nature provides complex and varied reservoirs of scaffolds and chemical entities that may have a pivotal role in the search for new therapeutic leads.

Mining Alzheimer's Interactomes, Macromolecular Complexes and Pathways for Drug Discovery

PROTEOMICS, Volume 25, Issue 21-22, Page 102-150, November 2025.
ABSTRACT Alzheimer's disease (AD) is a progressive neurodegenerative disorder that leads to dementia. Many cases are diagnosed annually and there is no currently available cure. Understanding the underlying disease biology of AD through the study of molecular networks, particularly by mapping clinical variants to tissue‐specific interactomes and ...
