Public perceptions of brain health in young and middle-aged adults in Cuba: Opportunities for intervention
Understanding brain health is increasingly important, particularly in light of growing public health challenges related to neurological and psychiatric conditions. These include the rising prevalence of mental health disorders, such as depression and anxiety, as well as neurodegenerative diseases like Alzheimer's and Parkinson's. Lifestyle factors, including stress, poor diet, and insufficient physical activity, also significantly impact cognitive function. Exploring the perceptions and...
Oligodendrocyte precursor cells facilitate neuronal lysosome release
Oligodendrocyte precursor cells (OPCs) shape brain function through many non-canonical regulatory mechanisms beyond myelination. Here we show that OPCs form contacts with their processes on neuronal somata in a neuronal activity-dependent manner. These contacts facilitate exocytosis of neuronal lysosomes. A reduction in the number or branching of OPCs reduces these contacts, which is associated with lysosome accumulation and altered metabolism in neurons and more senescent neurons with age. A...
Toward a biological definition of neuronal and glial synucleinopathies
Cerebral accumulation of alpha-synuclein (αSyn) aggregates is the hallmark event in a group of neurodegenerative diseases-collectively called synucleinopathies-which include Parkinson's disease, dementia with Lewy bodies and multiple system atrophy. Currently, these are diagnosed by their clinical symptoms and definitively confirmed postmortem by the presence of αSyn deposits in the brain. Here, we summarize the drawbacks of the current clinical definition of synucleinopathies and outline the...
Plasma proteomic evidence for increased β-amyloid pathology after SARS-CoV-2 infection
Previous studies have suggested that systemic viral infections may increase risks of dementia. Whether this holds true for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus infections is unknown. Determining this is important for anticipating the potential future incidence of dementia. To begin to do this, we measured plasma biomarkers linked to Alzheimer's disease pathology in the UK Biobank before and after serology-confirmed SARS-CoV-2 infections. SARS-CoV-2 infection was...
