Neurological disorders, such as trauma, stroke, epilepsy, and various neurodegenerative diseases, often lead to the permanent loss of neurons, causing significant impairments in brain function. Current treatment options are limited, primarily due to the challenge of replacing lost neurons.
Direct neuronal reprogramming, a complex procedure that involves changing the function of one type of cell into another, offers a promising strategy.
In cell culture and in living organisms, glial cells—the non-neuronal cells in the central nervous system—have been successfully transformed into functional neurons. However, the processes involved in this reprogramming are complex and require further understanding...
Read MoreDrugs that selectively kill senescent cells may benefit otherwise healthy older women but are not a “one-size-fits-all” remedy, Mayo Clinic researchers have found. Specifically, these drugs may only benefit people with a high number of senescent cells, according to findings publishing July 2 in Nature Medicine.
Senescent cells are malfunctioning cells in the body that lapse into a state of dormancy. These cells, also known as “zombie cells,” can’t divide but can drive chronic inflammation and tissue dysfunction linked to aging and chronic diseases. Senolytic drugs clear tissues of senescent cells.
In the 20-week, phase 2 randomized controlled trial, 60 healthy women past menopause intermittently received a senolytic combination composed of FDA-approved dasatinib and quercetin, a...
Read MoreA new study shows that suppressing a protein turns ordinary fat into a calorie burner and may explain why drug trials attempting the feat haven’t been successful.
Researchers at UC San Francisco have figured out how to turn ordinary white fat cells, which store calories, into beige fat cells that burn calories to maintain body temperature.
The discovery could open the door to developing a new class of weight-loss drugs and may explain why clinical trials of related therapies have not been successful.
Until now, researchers believed creating beige fat might require starting from stem cells...
