What is Down syndrome? This causes physical and mental developmental delays and disabilities.
Experimental studies in mice pregnant with Down syndrome pups showed that injecting them with nerve-protecting proteins could ease the extent of developmental delay in offspring.

Down syndrome occurs when children inherit an extra copy of chromosome 21 and the mice were engineered to have a similar condition by being given an extra copy of a segment of chromosome Both genetic abnormalities can lead to mental and developmental delays.
Researchers say that Down syndrome starved developing nerve cells of key proteins known as NAP and SAL which were needed for normal development.
When the pregnant mice were injected with these proteins, their Down-affected pups still reached their developmental milestones such as grasping a rod and responding to touch at the same speed as normal mice.
The brains of the treated mice also showed normal levels of other proteins normally found in reduced amounts where Down syndrome was present, providing more evidence that some effects of the syndrome had been removed. The scientists will continue to follow the mice to see if the effects are long-lasting or even permanent.
While it was too soon to say if the same success was possible in humans, the treatment offers hope of at least being able to lessen the symptoms.DSE Library Welcome to our online library.
Our online library offers access to many of our past publications, including many original research papers and insights into effective practice in education for young people with Down syndrome. Down syndrome is a set of cognitive and physical symptoms that result from having an extra chromosome 21 or an extra piece of that chromosome.
It is the most common chromosomal cause of mild to moderate intellectual disabilities.
