All processes such as wound healing, hair growth, and the replacement of old cells with new ones depend on cell division. During this process, chromosomes inside the cell must be evenly divided ...

Researchers have discovered the mechanism by which neurofibrillary tangles spread through the brain of Alzheimer's patients is via connected neurons, and these findings reveal a major disease etiology ...

In Alzheimer’s disease, two key proteins, extracellular amyloid-beta plaques and an intercellular protein called tau, disrupt communication between the brain’s cells and lead to cell damage and death.

Scientists have uncovered a surprising new role for little-known brain cells called tanycytes that may influence the development of Alzheimer’s disease. These specialized cells appear to help remove ...

Tau‑clearing cells in the brain may offer new clues to slowing Alzheimer’s disease progression, according to a study titled “Tanycytic degeneration impairs tau clearance and contributes to Alzheimer’s ...

The identification and validation of biomarkers for neurodegenerative diseases - particularly Alzheimer’s disease (AD) - is advancing rapidly. These biomarkers play a critical role in enabling early ...

Researchers at UC San Francisco have identified a hazardous waste collector in the brain that disposes of the toxic clumps of tau protein that can lead to dementia. Neurons with more of this garbage ...

Hyperphosphorylated tau, the protein that makes up the tangles observed in tauopathies like Alzheimer’s disease, may be the consequence of an antiviral mechanism intended to protect the brain from ...
