Hope for reversing stroke-induced long-term disability
Permanent brain damage from a stroke may be reversible thanks to a developing therapeutic technique, a study has found. The novel approach combines transplanted human stem cells with a special protein that the US Food and Drug Administration already approved for clinical studies in new stroke patients. The researchers say they are the first to use 3K3A-APC to produce neurons from human stem cells grafted into the stroke-damaged mouse brain.

Transplanted neurons incorporated into a stroke-injured rat brain
Today, a stroke usually leads to permanent disability – but in the future, the stroke-injured brain could be reparable by replacing dead cells with new, healthy neurons, using transplantation. Researchers have taken a step in that direction by showing that some neurons transplanted into the brains of stroke-injured rats were incorporated and responde d correctly when the rat’s muzzle and paws were touched.

Molecular mechanism behind health benefits of dietary restriction identified
A key molecular mechanism behind the health benefits of dietary restriction has been identified by researchers. Also known as calorie restriction, dietary restriction is best known for its ability to slow aging in laboratory animals. The findings here show that restricting two amino acids, methionine and cysteine, results in increased hydrogen sulfide (H2S) production and protection against ischemia reperfusion injury, damage to tissue that occurs following the interruption of blood flow as during organ transplantation and stroke.
