Morphofunctional Changes in Brain and Peripheral Blood in Adult and Aged Wistar Rats with AlCl-Induced Neurodegeneration.

Background: the general lifespan has been prolonged greatly during the past century, and the incidence of age-associated diseases, including neurodegenerative ones, has increased as well. However, modelling of age-related pathologies is mostly conducted on adult rodents. We studied morphofunctional changes in the brain and peripheral blood of adult Wistar rats in comparison with old Wistar rats to determine age-related physiological changes and differences in adaptive reactions to AlCl exposure.

Alzheimer's Disease and Inflammaging.

Alzheimer's disease is one of the most common age-related neurodegenerative disorders. The main theory of Alzheimer's disease progress is the amyloid-β cascade hypothesis. However, the initial mechanisms of insoluble forms of amyloid-β formation and hyperphosphorylated tau protein in neurons remain unclear.
