Researchers have explained how a protein found in both yeast and humans facilitates the destruction of the core protein responsible for Parkinson's disease. An aggregate that impairs clearance Loss of ProteostasisThe loss of proteostasis is the failure of the protein-building machinery of the cell and the accumulation of misfolded proteins, which is one of the...

According to a new study, a special protein disposal system, currently found only in neurons, is linked to central hallmarks of Alzheimer’s disease [1]. The membranal proteasome Loss of ProteostasisThe loss of proteostasis is the failure of the protein-building machinery of the cell and the accumulation of misfolded proteins, which is one of the root...

In a recent study, scientists have demonstrated that lysosomal dysfunction actively decreases the potency of hematopoietic stem cells. Calming lysosomes reversed this process, opening avenues for new treatments [1]. Few and far between Hematopoietic stem cells (HSCs) are rare and precious: they produce blood progenitor cells, which, in turn, produce all differentiated blood cells. With...

Research published in Aging Cell has revealed that a nematode species commonly used for aging research lives much longer on an alternate-day fasting regimen, but only when it is administered in middle age and only when the worms are consuming an animal-based protein source. Deciding what to restrict and when Dietary restriction practices have been...

A study published in Nature Aging has shown that short-term rapamycin treatment in early adulthood extends lifespan in flies and improves gut health in both flies and mice [1]. A well-studied drug Rapamycin, an inhibitor of mTOR signaling, is capable of extending the lifespan of several organisms and is thus believed to be one of...
