Gene therapy technique slows brain disease

Progeny of HSCs that were engineered to carry the correct version of a gene (through the

some cells replaced diseased microglia in the brain and relieved lipid storage in patients
suffering from ALD.A strategy that combines gene therapy with blood stem cell therapy may be a useful tool for treating a fatal brain disease, French researchers have found. These findings appear in...
