Down syndrome, of all the genetic defects people are born with, is the most common (as far as chromosomal abnormalities go). Down syndrome involves having a third copy of all or part of chromosome 21 (for those who do not recall we are typically born with 23 pairs of chromosomes). In addition to intellectual disability, individuals with Down syndrome have a high risk of congenital heart defects. However, not all people with Down syndrome have them – about half have structurally normal hearts.
At first glance the title might sound a little weird. But if that is the case then you probably want to read this. Researchers have identified a group of cells in the brain that they say plays an important role in the abnormal neuron development in Down syndrome. After developing a new model for studying the syndrome using patient-derived stem cells [over other models]. As the title alluded to, the scientists also found that applying an inexpensive antibiotic to the cells appears to correct many abnormalities in the interaction between the cells and developing neurons.
