Targeting key gene could help lead to down syndrome treatment

Using stem cells from candidates with Down syndrome to create an organoid, and employing mouse models, researchers pinpoint a gene linked to memory impairments and cognitive problems in Down syndrome. Inhibiting the OLIG2 gene leads to cognitive and memory improvements in mouse models of Down. Researchers hope their findings lead to an in utero treatment that targets the gene and helps reverse abnormal brain development.
