 Down syndrome is the main cause of intellectual disability. It is caused by the trisomy of chromosome 21. And the intellectual disability is thought to arise from the defects in the process called neurogenesis, which is the process in which neurons themselves divide and generate neurons, which then make the human brain. In case of the Down syndrome, fine defects in the process of neurogenesis can result in the reduced number of neurons that are produced, which then will result in the reduced size of the brain and will cause the intellectual disability. In our lab at Human Technopole, we are interested in studying these processes at the molecular and cellular level to understand these defects. And we hope that our research in the future can lead to new prenatal therapies that will help these patients.
