Muscle wasting in cancer cachexia: Mechanisms and the role of exercise

open access: yesExperimental Physiology, EarlyView.
Abstract Cancer cachexia (CC) is a multifactorial disease marked by a severe and progressive loss of lean muscle mass and characterized further by inflammation and a negative energy/protein balance, ultimately leading to muscle atrophy and loss of muscle tissue.

Chronic Caffeine Treatment Protects Against α-Synucleinopathy by Reestablishing Autophagy Activity in the Mouse Striatum

open access: yesFrontiers in Neuroscience, 2018
Despite converging epidemiological evidence for the inverse relationship of regular caffeine consumption and risk of developing Parkinson's disease (PD) with animal studies demonstrating protective effect of caffeine in various neurotoxin models of PD ...

Cell Surface Markers Identify Astrocyte Subpopulations in the Adult Hippocampus With a Heterogeneous Response to Aging

open access: yesGlia, Volume 74, Issue 11, November 2026.
ATP1B2 and GLAST identify two astrocyte subpopulations in the hippocampus with distinct molecular signatures. Transcriptomic shifts during aging differ between both subpopulations. Aged ATP1B2+ astrocytes rewire their metabolism while double‐positive aged astrocytes display a reduced synaptogenic capability.

Insights into the modulation of age‐related macular degeneration: Molecular and systems‐level perspectives

open access: yesActa Ophthalmologica, Volume 104, Issue S293, Page S4-S35, October 2026.
ENGLISH SUMMARY In developed countries, age‐related macular degeneration (AMD) is the leading cause of visual impairment in the aging population. Understanding of its pathogenesis is limited and the number of patients is predicted to continue rising. AMD is classified into two main forms: dry and neovascular AMD (dAMD and nAMD, respectively).

Three-Dimensional Ultrastructure of Arabidopsis Cotyledons Infected with Colletotrichum higginsianum

open access: yesMolecular Plant-Microbe Interactions
We used serial block-face scanning electron microscopy (SBF-SEM) to study the host–pathogen interface between Arabidopsis cotyledons and the hemibiotrophic fungus Colletotrichum higginsianum.

SIRT1 in Neurodegenerative Diseases: Molecular Mechanisms, Disease Relevance, and Therapeutic Potential

open access: yesThe FASEB Journal, Volume 40, Issue 17, 15 September 2026.
SIRT1, an NAD+‐dependent deacetylase, supports cognitive resilience by coordinating neuroprotection, synaptic plasticity, autophagy–lysosomal proteostasis, and mitochondrial energy homeostasis. Reduced or dysregulated SIRT1 is associated with protein aggregation, neuroinflammation, mitochondrial dysfunction, synaptic loss, and cognitive decline in ...

Amino acid sensory complex proteins in mTORC1 and macroautophagy regulation

open access: yes, 2021
Autophagy is the highly conserved catabolic process, which enables the survival of a cell under unfavorable environmental conditions. In a constantly changing environment, cells must be capable of dynamically oscillating between anabolism and catabolism ...

Antigen processing for MHC presentation via macroautophagy

open access: yes, 2012
Macroautophagy has recently emerged as an important catabolic process involved not only in innate immunity but also in adaptive immunity. Initially described to deliver intracellular antigens to MHC class II loading compartments, its molecular machinery ...

Macroautophagy regulates CD4+ T cell function

open access: yes, 2011
Protein turnover is imperative for the diminution and removal of accumulated damaged proteins in the cell. Turnover is also essential to facilitate recycling of amino acids for new protein synthesis and to allow for the modification of protein levels in ...

The nonsense-mediated mRNA decay factor Upf3 negatively regulates bulk autophagy progression in Saccharomyces cerevisiae

open access: yesAutophagy Reports
Macroautophagy/Autophagy is a highly conserved mechanism that targets cytoplasmic cargo for degradation and recycling. At present, 45 autophagy-related (ATG) genes have been identified in fungi.
