Ai os viçosos cabelos da juventude e a juventude...

... À distância de uma proteína estudada em ratos (outro estudo publicado esta semana):

Citando:
"Researchers investigated whether a modified version of a protein called FOXO4-DRI was able to "seek and destroy" senescent cells from mice, in the hope this may counteract signs of ageing.
Researchers used naturally ageing mice as well as mice genetically modified to age more rapidly. They exposed both sets of mice to toxic chemotherapy drugs to place additional stress on their cellular functions.
They found FOXO4-DRI was able to neutralise toxicity caused by chemotherapy in the rapidly ageing and naturally ageing mice. It was also able to counteract loss of liver and kidney function, frailty and loss of fur density in the mice.
This is very early stage animal research and further studies are needed before FOXO4-DRI can be tested in humans.
It is likely that further research on FOXO4-DRI will be carried out, as a drug that could treat both hair loss and reverse some of the effects of ageing would have considerable commercial potential."
