Autophagy News and Research

RSS

Autophagy is a normal process in which a cell destroys proteins and other substances in its cytoplasm (the fluid inside the cell membrane but outside the nucleus), which may lead to cell death. Autophagy may prevent normal cells from developing into cancer cells, but it may also protect cancer cells by destroying anticancer drugs or substances taken up by them.

Could a diabetes drug be the key to stopping Alzheimer’s?

Investigating tirzepatide's role in Alzheimer's reveals its potential to improve brain function and reduce inflammation, linking diabetes and neurodegeneration.

What happens to your body and mind during a five-day water fast?

A five-day water-only fast led to significant weight, fat, and lean muscle loss in middle-aged women, along with improved mood and marked changes in metabolic and inflammatory markers. The study also found that psychological traits like emotional intelligence and impulsivity influenced the amount of fat and muscle lost during fasting.

Sucralose disrupts male fertility by damaging sperm and altering hormones in animal study

Researchers found that chronic sucralose exposure in male rats disrupted reproductive hormones, damaged sperm, and impaired testicular function through oxidative stress and autophagy dysregulation. These findings raise concerns about the reproductive risks of high sucralose intake and its persistent presence in the environment.

Peptide nanostructures block amyloid buildup and boost neuron survival in lab tests

Researchers developed trehalose-functionalized peptide amphiphiles (TPAs) that self-assemble into supramolecular nanostructures and demonstrated these TPAs can inhibit amyloid beta aggregation. In vitro, TPAs significantly improved survival of human neurons exposed to amyloid-induced neurotoxicity, suggesting therapeutic potential for neurodegenerative diseases.
