The waste-disposal system in a cell can spread harmful protein aggregates between neurons in the brain in Alzheimer’s disease. The spread can be reduced in experiments in cultivated cells. The discovery may help the development of new diagnostic methods, and may eventually lead to new drugs that can stop or reduce the progression of disease.

An international team of scientists have developed a new way to screen for age-related cognitive decline at home using a test which asks people to detect sounds and flashes on their laptop or phone.
Researchers may have found a group of immune cells that increase in number with age but are too worn out to fight diseases. The accumulation of dysfunctional virtual memory T cells, in addition to the loss of true naïve T cells, may explain why older people have reduced immune responses to cancer and vaccines, why cancer immunotherapy is less successful in the elderly, and may help to tailor cancer immunotherapy treatments specifically for older patients.
New research demonstrates that Na/K-ATPase oxidant amplification loop (NAKL) is intimately involved in the aging process and may serve as a target for anti-aging interventions.
In a large-scale analysis, researchers use data from three different brain banks to suggest that human herpesviruses are more abundant in the brains of Alzheimer’s patients and may play a role in regulatory genetic networks that are believed to lead to the disease. This work lends support to the controversial hypothesis that viruses are involved in Alzheimer’s disease and offers potential new paths for treatment.
A low-dose aspirin regimen may represent a new avenue for reducing Alzheimer’s disease pathology, according to new research in a mouse model. The study identifies a new role for one of the most widely used medications in the world.
The chances of reaching the ripe old age of 110 are within reach — if you survive the perilous 90s and make it to 105 when death rates level out, according to a study of extremely old Italians.
A new study has found that the female bladder not only contains bacteria, but the microbes are similar to those found in the vagina. The finding could lead to improved diagnostic tests and treatments for urinary tract infections and other urinary tract disorders.
