Activation of the proteasomal degradation of misfolded proteins has been proposed as a therapeutic strategy for treating neurodegenerative diseases, but it is unclear whether proteasome dysfunction contributes to neurodegeneration. We tested the role of proteasome activity in neurodegeneration developed by mice lacking cysteine string protein-α (CSPα). Unexpectedly, we found that proteasome inh...

Microglia, the tissue-resident macrophages in the brain, are damage sensors that react to nearly any perturbation, including neurodegenerative diseases such as Alzheimer's disease (AD). Here, using single-cell RNA sequencing, we determined the transcriptome of more than 1,600 individual microglia cells isolated from the hippocampus of a mouse model of severe neurodegeneration with AD-like pheno...

Alzheimer’s disease (AD) is the most popular type of dementia in elderly and is described by a progressive loss of cognitive capacity and severe neurodegeneration which typically begins with memory deficits. The major biomarkers of AD include total tau, phosphorylated-tau and 42 amino acid isoform of amyloid beta that reflect neurodegeneration and indicate the pathophysiological processes in AD...

Neurofibrillary tangles (NFT) containing tau are a hallmark of neurodegenerative diseases, including Alzheimer's disease (AD). NFT burden correlates with cognitive decline and neurodegeneration in AD. However, little is known about mechanisms that protect against tau-induced neurodegeneration. We used a cross species functional genomic approach to analyze gene expression in multiple brain regio...

One characteristic neuropathological feature of Alzheimer's disease (AD) is profound neuronal loss in the nucleus basalis of Meynert, the major source of cholinergic innervation of the cerebral cortex. Clinically, anticholinergic activity causes a decline in cognitive function and increases the risk of dementia, thus possibly enhancing AD pathologies and neurodegeneration. Until now there has b...

INTRODUCTION Neurodegeneration is an early component of diabetic retinopathy (DR). It is unclear whether neurodegeneration is an independent factor or a consequence of damaged retinal vasculature. The aims of this study were to review the literature concerning neurodegeneration in diabetic patients without or with early DR, and to examine whether neurodegeneration precedes visible vasculopathy ...

Neurodegeneration is a hallmark of most of the central nervous system (CNS) disorders including stroke. Recently inflammation has been implicated in pathogenesis of neurodegeneration and neurodegenerative diseases. The aim of this study was analysis of expression of several inflammatory markers and its correlation with development of neurodegeneration during the early stage of experimental stro...

Neurodegeneration has been correlated with mitochondrial DNA (mtDNA) damage and exposure to environmental toxins, but causation is unclear. We investigated the ability of several known environmental genotoxins and neurotoxins to cause mtDNA damage, mtDNA depletion, and neurodegeneration in Caenorhabditis elegans. We found that paraquat, cadmium chloride and aflatoxin B1 caused more mitochondria...

Neurodegeneration and aging are pressing issues with significant personal, economic, ethical, social consequences. However, the underlying biological mechanisms of these conditions remain largely unknown, making development effective treatments challenging. The difficulty in early detection diagnosis neurodegenerative diseases further compounds issue. Recent advancements genetics, genomics, bra...
