Monkeys with Autism?
“…first ever nonhuman primates to show autism-like symptoms in the lab.”
On January 25, news broke widely in the press on research published in Nature by a team in Shanghai, who spent six years creating two generations of macaque monkeys engineered to have duplications of the MECP2 gene in their brains—a gene that researchers have associated with Rett Syndrome, a condition on the severe end of the human autism spectrum.
The researchers listed a battery of behavioral tests which they claimed as evidence that the transgenic monkeys were now genetically predisposed to autism-associated behaviors. In a press briefing organized by Nature, Zilong Qiu, a leader of research at the Institute of Neuroscience at the Chinese Academy of Sciences, stated plans to leverage their research into human clinical trials down the line, with the aim of developing somatic gene therapies or non-invasive interventions like trans-cranial magnetic stimulation [Wiki] to correct autism in humans. Qiu stated the researchers are currently trying to identify the brain circuitry responsible for what they believe is the monkeys’ changed, autism-like behavior; after that, they plan to use CRISPR-Cas9 gene editing to manipulate the MECP2 duplications in the transgenic monkeys they created.
With “autism,” “transgenic,” and “monkey” in the headlines, it’s not surprising that a flurry of media coverage might flatten the social and ethical implications of what’s at stake with using animals models to study stigmatized human behavioral conditions. One article was promoted on Twitter as “First Monkeys with Autism are Sickly Loners Who Pace Their Cages.”
