Background: Extracellular vesicles (EVs) have been considered promising tools in regenerative medicine. However, the nanoscale properties of EVs make them sensitive to environmental conditions. Optimal storage protocols are crucial for maintaining EV structural, molecular, and functional integrity.

Background: Alzheimer's disease (AD) is the most common human neurodegenerative disorder worldwide. Owing to its chronic nature, our limited understanding of its pathophysiological mechanisms, and because of the lack of effective anti-AD drugs, AD represents a significant socio-economic challenge for all industrialized countries. Neuronal cell death is a key factor in AD pathogenesis and recent studies have suggested that neuronal ferroptosis may play a major patho-physiological role.

Article Synopsis
  • - CSF1R-related disorder (CSF1R-RD) is a genetic neurodegenerative disease primarily affecting white matter due to mutations in the CSF1R gene, leading to a decline in brain function, particularly in an elderly man studied who showed symptoms of progressive dementia.
  • - Brain autopsy revealed features characteristic of adult-onset leukoencephalopathy (ALSP) associated with CSF1R-RD, and a novel genetic deletion in CSF1R was uncovered, which standard genetic tests hadn't detected.
  • - Further genomic analysis indicated two distinct states of microglia associated with the disease and showed that oligodendrocytes, critical for myelin formation, exhibited stress responses and failed to mature properly

Alzheimer's disease (AD) is the most prevalent neurodegenerative disease worldwide and has a great socio-economic impact. Modified oxidative lipid metabolism and dysregulated iron homeostasis have been implicated in the pathogenesis of this disorder, but the detailed pathophysiological mechanisms still remain unclear. Apolipoprotein E (APOE) is a lipid-binding protein that occurs in large quantities in human blood plasma, and a polymorphism of the APOE gene locus has been identified as risk factors for AD.
