Low pleiotrophin levels may worsen brain issues in Down syndrome; restoring it helped mice, but human treatments are years away.
Scientists have found that low levels of the protein pleiotrophin in brain cells may contribute to neurological challenges in Down syndrome.
In mice, restoring pleiotrophin improved brain function, learning, and memory, even in adults, by enhancing neural connections.
The protein, normally produced by supportive astrocytes, could be delivered via gene therapy or protein infusions, offering a potential treatment path.
While promising, the research is early-stage and not yet applicable to humans.
The study, funded by the NIH and Chan Zuckerberg Initiative, suggests broader implications for conditions like Alzheimer’s and fragile X syndrome.
Los niveles bajos de pleiotrofina pueden empeorar los problemas cerebrales en el síndrome de Down; restaurarlo ayudó a los ratones, pero los tratamientos humanos están a años de distancia.
