THIS ARTICLE IS MORE THAN FIVE YEARS OLD
This article is more than five years old. Autism research — and science in general — is constantly evolving, so older articles may contain information or theories that have been reevaluated since their original publication date.
Our picks for the top papers of the year highlight leaps in our understanding of autism as well as lingering gaps.
This year, as we do every year, we asked scientists to help us choose the 10 most ‘notable’ autism papers — ones that transformed the field in some significant way.
The final selection highlights several advances in the field. Researchers are homing in on immune molecules that may play a role in autism risk. And new tools, from genetically engineered animals to massive genetic databases, will be a boon to future research.
Our list also spotlights knowledge gaps. For example, people with autism are more likely to die prematurely than are those without the condition. But the reason for this disparity is unclear.
Here, in reverse chronological order, are the papers that made the cut.
Teaching parents of toddlers with autism how to recognize and respond to their children may spark stable improvements in the children’s social communication and other autism features.
Pickles A. et al. Lancet 388, 2501-2509 (2016) PubMed
Edging out at least five other teams, a Japanese group became the first to publish findings on mice lacking CHD8, the leading candidate gene for autism risk.
Katayama Y. et al. Nature 537, 675-679 (2016) PubMed
A landmark collection of DNA sequences from more than 60,000 people provided an unprecedented picture of genetic variation across the general population.
Lek M. et al. Nature 536, 285-291 (2016) PubMed
Mice with either too much or too little MeCP2, the gene mutated in Rett syndrome, show similar malfunctions in a learning and memory brain circuit.
Lu H. et al. Neuron 91, 739-747 (2016) PubMed
Nearly half of children with autism who speak few or no words have cognitive skills that far exceed their verbal abilities.
Bal V.H. et al. J. Child Psychol. Psychiatry 57, 1424-1433 (2016) PubMed
Molecules that protect the body from infection may be needed for mice to socialize with their peers. This double duty could help safeguard the health of animals that live in close quarters.
Filiano A.J. et al. Nature 535, 425-429 (2016) PubMed
The anxiety and trouble with social skills seen in people with autism stem largely from neurons outside the brain that govern touch.
Orefice L. et al. Cell 166, 299-313 (2016) PubMed
An immune molecule in pregnant mice produces autism-like behaviors in their pups. The findings support the theory that infections during pregnancy raise the risk of autism, and hint at a way to mitigate the risk.
Choi G.B. et al. Science 351, 933-939 (2016) PubMed
Genes that are expressed at higher levels in men’s brains than in women’s also tend to be enriched in the brains of people with autism. Many of these genes are markers for immune cells called microglia, which have been implicated in autism.
Werling D.M. et al. Nat. Commun. 7, 10717 (2016) PubMed
People with autism are more than twice as likely as their peers in the general population to die prematurely. The finding adds to evidence suggesting that gaps in preventive care can cause serious health problems in people with autism.
