Disease-associated microglia in neurodegenerative diseases: Friend or foe?
Recent advances in single-cell transcriptomics have led to the identification of disease-associated microglia (DAM) as a distinct, conserved microglia state associated with mouse models of Alzheimer's disease (AD) and amyotrophic lateral sclerosis, and with aging. DAM are characterized by downregulation of homeostatic genes and upregulation of lipid metabolism and phagocytosis genes, including key risk factors for AD in humans. Although characterized in models of AD, whether DAM acts as...

A paradoxical role of autophagy: promoting protein aggregates and hindering rejuvenation in a Caenorhabditis elegans L1 arrest model
Macroautophagy (hereafter referred to as autophagy) is widely recognized as a central pathway for the clearance of protein aggregates and the maintenance of proteostasis. However, a recent study by Murley et al. challenges this conventional view. Using a Caenorhabditis elegans L1 arrest aging model, the authors found that autophagy activation impedes rejuvenation by promoting the accumulation of intra- 10 lysosomal protein aggregates and inducing lysosomal membrane damage. This unexpected...
Single-Cell RNA Sequencing Identifies Accumulation of Fcgr2b + Virtual Memory-Like CD8 T Cells With Cytotoxic and Inflammatory Potential in Aged Mouse White Adipose Tissue
Aging and obesity are associated with pro-inflammatory changes in adipose tissue. Overlapping mechanisms, such as the infiltration of inflammatory macrophages and T cells into visceral adipose tissue, have been implicated in contributing to inflammation. However, a comparative analysis of both states is needed to identify distinct regulatory targets. Here, we performed single-cell RNA sequencing of stromal vascular fractions (SVF) isolated from gonadal white adipose tissue (gWAT) of young mice...
An Ad Libitum-Fed Diet That Matches the Beneficial Lifespan Effects of Caloric Restriction but Acts via Opposite Effects on the Energy-Splicing Axis
Caloric restriction (CR) with fasting extends lifespan but is difficult to maintain in humans. Here, we compared conventional CR with periods of fasting to an ad libitum-fed low-protein, high-carbohydrate (LPHC) diet diluted 25% with non-digestible fibre. Both approaches similarly enhanced longevity and metabolic health in mice relative to a control diet. Proteomic analysis of liver tissue revealed that CR increased proteins associated with energy and mitochondrial pathways. By contrast, the...
