Biofabrication of nanovesicles for brain diseases

Neural Regeneration Research, 2023
Nanotechnologies promise to improve disease diagnosis and treatment, overcoming the limitations of conventional administrations. In particular, extracellular vesicles (EVs) and artificial vesicles (AVs) are strongly emerging tools in nanomedicine (Leggio et al., 2020). EVs are cell-derived membrane structures secreted after the fusion of endosomes with

Redox‐dependent binding and conformational equilibria govern the fluorescence decay of NAD(P)H in living cells

FEBS Letters, EarlyView.
In this work, we reveal how different enzyme binding configurations influence the fluorescence decay of NAD(P)H in live cells using time‐resolved anisotropy imaging and fluorescence lifetime imaging microscopy (FLIM). Mathematical modelling shows that the redox states of the NAD and NADP pools govern these configurations, shaping their fluorescence ...

Ergothioneine supplementation improves pup phenotype and survival in a murine model of spinal muscular atrophy

FEBS Letters, EarlyView.
Spinal muscular atrophy (SMA) is a genetic disease affecting motor neurons. Individuals with SMA experience mitochondrial dysfunction and oxidative stress. The aim of the study was to investigate the effect of an antioxidant and neuroprotective substance, ergothioneine (ERGO), on an SMNΔ7 mouse model of SMA.

Serial amplification of tau filaments using Alzheimer's brain homogenates and C322A or C322S recombinant tau

FEBS Letters, EarlyView.
We investigated the seeded assembly of 0N3R tau and two variants, C322A and C322S, designed to model the mutation landscape at residue 322, using Alzheimer's disease brain homogenates in a real‐time quaking‐induced conversion (RT‐QuIC) assay. The C322A variant formed filaments that partially resembled the paired helical filament (PHF) structure ...

ACSS2 involved in acetyl‐CoA synthesis regulates skeletal muscle function

FEBS Letters, EarlyView.
The enzyme acyl‐coenzyme A synthetase short‐chain family member‐2 (ACSS2) catalyzes the conversion of acetate to acetyl‐CoA, but its function in skeletal muscle is unclear. We studied ACSS2 deficiency in mouse and fly models. Skeletal muscle from the mouse model showed atrophic fibers, excess lipid, and depleted NADH.

Nanocarriers based therapy and diagnosis of brain diseases: cross the blood-brain barrier

Science and Technology of Advanced Materials
The blood-brain barrier (BBB) is the protective interface that isolates the central nervous system from circulating blood, which restricts approximately 98% of small molecule drugs and nearly all large molecules from entering the brain.

A working model for cytoplasmic assembly of H/ACA snoRNPs

FEBS Letters, EarlyView.
Dyskerin is the component of nuclear H/ACA ribonucleoproteins (RNPs) endowed with pseudouridine synthase catalytic activity. Two isoforms of human dyskerin have been characterized: the abundant Iso1, mainly nuclear, and the shorter Iso3, mainly cytoplasmic but occasionally imported into nuclei.

Novel and unscrutinized immune entities of the zebrafish gut

FEBS Letters, EarlyView.
Understudied cells of the zebrafish immune system include bona fide immune cells and epithelial (‐derived) cells with immune functions. Research focusing on zebrafish cells which demonstrate similarities to mammalian immune cell counterparts may help us understand the pathologies in which they are implicated. Currently available and advanced tools make
