Enhancing mitochondrial quality control to fight neuromuscular degeneration in aging and disease

Loss of mitochondrial function and proteostasis typify aging and age-associated degenerative disorders such as Alzheimer's disease and muscle aging. To date, no cure or preventive measure is available to manage these conditions. Alterations of cellular pro ...

Following spatial A beta aggregation dynamics in evolving Alzheimer's disease pathology by imaging stable isotope labeling kinetics

Anders Meibom, Stéphane Laurent Escrig, Melissa Kathleen Passarelli

beta-Amyloid (A beta) plaque formation is the major pathological hallmark of Alzheimer's disease (AD) and constitutes a potentially critical, early inducer driving AD pathogenesis as it precedes other pathological events and cognitive symptoms by decades. ...

Pharmacological characterization of mutant huntingtin aggregate-directed PET imaging tracer candidates

Hilal Lashuel, Anass Chiki

Huntington's disease (HD) is caused by a CAG trinucleotide repeat expansion in the first exon of the huntingtin (HTT) gene coding for the huntingtin (HTT) protein. The misfolding and consequential aggregation of CAG-expanded mutant HTT (mHTT) underpin HD p ...

Cholesterol Hinders the Passive Uptake of Amphiphilic Nanoparticles into Fluid Lipid Membranes

Francesco Stellacci, Matteo Gasbarri, Ester Canepa, Giulia Rossi

Plasma membranes represent pharmacokinetic barriers for the passive transport of site-specific drugs within cells. When engineered nanoparticles (NPs) are considered as transmembrane drug carriers, the plasma membrane composition can affect passive NP inte ...

Lewy body-associated proteins: Victims, instigators, or innocent bystanders? The case of AIMP2 and alpha-synuclein

Hilal Lashuel, Salvatore Novello

Lewy bodies (LBs), one of the neuropathological defining hallmarks of Parkinson's disease (PD), are composed of a complex mixture of alpha-synuclein (aSyn) filaments and hundreds of proteins, lipids, and membranous organelles. However, these proteins' role ...

NAD+ boosting reduces age-associated amyloidosis and restores mitochondrial homeostasis in muscle

Johan Auwerx, Hongbo Zhang, Hao Li, Vincenzo Sorrentino, Mario Romani, Changmyung Oh, Tanes Imamura de Lima

Aging is characterized by loss of proteostasis and mitochondrial homeostasis. Here, we provide bioinformatic evidence of dysregulation of mitochondrial and proteostasis pathways in muscle aging and diseases. Moreover, we show accumulation of amyloid-like d ...

EASI-FISH for thick tissue defines lateral hypothalamus spatio-molecular organization

Hui Yang, Martin Weigert

Determining the spatial organization and morphological characteristics of molecularly defined cell types is a major bottleneck for characterizing the architecture underpinning brain function. We developed Expansion Assisted Iterative Fluorescence In Situ H ...

To target Tau pathologies, we must embrace and reconstruct their complexities

Hilal Lashuel, Galina Limorenko

The accumulation of hyperphosphorylated fibrillar Tau aggregates in the brain is one of the defining hallmarks of Tauopathy diseases, including Alzheimer's disease. However, the primary events or molecules responsible for initiation of the pathological Tau ...
