Introduction
Proteolytic processing of amyloid protein precursor by β-site secretase enzyme (BACE1) is dependent on the cellular lipid composition and is affected by endomembrane trafficking in dementia and Alzheimer's disease (AD). Stearoyl-CoA desaturase 1 (SCD1) is responsible for the synthesis of fatty acid monounsaturation (MUFAs), whose accum...
In response to brain insults, astrocytes become reactive, promoting protection and tissue repair. However, astroglial reactivity is typical of brain pathologies, including Alzheimer's disease (AD). Considering the heterogeneity of the reac-tive response, the role of astrocytes in the course of different forms of AD has been underestimated. Colombia...

Cerebral ischemia is the most common cause of disability, the second most common cause of dementia, and the fourth most common cause of death in the developed world [Sveinsson OA, Kjartansson O, Valdimarsson EM. Heilablóðþurrð/heiladrep: Faraldsfræði, orsakir og einkenni [Cerebral ischemia/infarction - epidemiology, causes and symptoms]....
Glutamate excitotoxicity triggers overactivation of CDK5 and increases calcium influx in neural cells, which promotes dendritic retraction, spine loss, increased mitochondrial calcium from the endoplasmic reticulum, and neuronal death. Our previous studies showed that CDK5 knockdown (KD) in astrocytes improves neurovascular integrity and cognitive...
Dysfunction in the neurovascular unit (NVU) is a key component in the progressive deterioration of Alzheimer’s disease (AD) and is critical in vascular dementia. Recent studies have shown that inflammation plays early and perhaps causal roles in the pathogenesis of AD related to NVU damage, possibly in part by overactivating the aspartic acid prote...
Astrocytes are specialized glial cells that are essential components of the neurovascular unit (NVU) and are involved in neurodevelopment, brain maintenance and repair, and neurodegeneration. Astrocytes mediate these processes by releasing cellular mediators such as extracellular vesicles (EVs). EVs are vehicles of cell-cell communication and have...
An imbalance in lipid metabolism in Alzheimer disease (AD) is still poorly understood. Phospholipids (PLs) have multifactorial participation in AD, including the hyperactivation of phospholipases, mitochondrial stress, peroxisomal dysfunction, and irregular fatty acid composition. The reestablishment of physiological conditions of cholesterol, sphi...
Evidence suggests that extracellular vesicles (EVs) act as mediators and biomarkers of neurodegenerative diseases. Two distinct forms of Alzheimer disease (AD) are known: a late-onset sporadic form (SAD) and an early-onset familial form (FAD). Recently, neurovascular dysfunction and altered systemic immunological components have been linked to AD n...
