Nanodiamond Quantum Sensors for Probing Free Radical Biology

Advanced Functional Materials, Volume 36, Issue 45, 5 June 2026.
Free radicals play key roles in cellular signaling and disease but remain difficult to measure in living systems. Nanodiamonds (NDs) with nitrogen‐vacancy (NV) centers enable quantum sensing of local magnetic noise via T₁ relaxometry, providing nondestructive radical detection in living cells.

Proteins with Intrinsically Disordered Domains Are Preferentially Recruited to Polyglutamine Aggregates

PLOS ONE, 2015
Intracellular protein aggregation is the hallmark of several neurodegenerative diseases. Aggregates formed by polyglutamine (polyQ)-expanded proteins, such as Huntingtin, adopt amyloid-like structures that are resistant to denaturation. We used a novel purification strategy to isolate aggregates formed by human Huntingtin N-terminal fragments with ...

Light‐Controlled Peptide Self‐Assembly: From Physicochemical Principles to Emerging Biomedical Applications

Aggregate, Volume 7, Issue 6, June 2026.
This review surveys recent advances in light‐controlled peptide self‐assembly for the design of smart soft matter. It summarizes the underlying physicochemical principles, including thermodynamic control for reshaping free‐energy landscapes, and nonequilibrium control to produce kinetically trapped states and dissipative structures.

Disruption of the nascent polypeptide-associated complex leads to reduced polyglutamine aggregation and toxicity.

PLoS ONE
The nascent polypeptide-associate complex (NAC) is a heterodimeric chaperone complex that binds near the ribosome exit tunnel and is the first point of chaperone contact for newly synthesized proteins.

The Effect of Protein Tagging on Aggregation and Phase Separation

Journal of Cellular Biochemistry, Volume 127, Issue 6, June 2026.
ABSTRACT Protein tags are widely used for purification, solubilization, detection, and imaging, yet they can substantially alter protein self‐assembly. This interference is particularly significant for intrinsically disordered proteins and low‐complexity domains, whose aggregation and phase separation are mediated by weak multivalent interactions that ...

Exploring and Targeting the Connection of Iron and Copper Homeostasis to Neurodegenerative Diseases

MedComm, Volume 7, Issue 6, June 2026.
Iron and copper dyshomeostasis, along with their interactions with key intrinsically disordered proteins (e.g., Aβ, tau, α‐synuclein) have a strong implication in the onset and progression of neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), Prion diseases (PrDs), Huntington's disease (HD), Wilson's disease (WD),

Targeting Mitochondria in Aging‐Related Diseases: Therapeutic Potential and Obstacles

MedComm, Volume 7, Issue 6, June 2026.
This article systematically summarized the specific mechanism of aging‐related diseases caused by mitochondrial dysfunction, and summarized the broad‐spectrum treatment methods and disease targeted treatment strategies for mitochondria. At the same time, it also pointed out the dilemma faced by mitochondrial targeted treatment.

Modulation of the Stress Granule Component Carhsp1 Mitigates Disease‐Associated Deficits in Spinocerebellar Ataxia Type 3 Mouse Models

Movement Disorders, Volume 41, Issue 6, Page 1516-1527, June 2026.
Abstract Background Spinocerebellar ataxia type 3 (SCA3) is a polyglutamine (polyQ) neurogenerative disorder that results from CAG trinucleotide repeat expansions in the ATXN3 gene, leading to toxic protein aggregate formation and cellular pathway dysfunction.

Rescue of ATXN3 neuronal toxicity in Caenorhabditis elegans by chemical modification of endoplasmic reticulum stress

Disease Models & Mechanisms, 2017
Polyglutamine expansion diseases are a group of hereditary neurodegenerative disorders that develop when a CAG repeat in the causative genes is unstably expanded above a certain threshold.
