[MEDICINE] Autistic people are part bee [SCIENCE] (13)

> Antisocial bees share genetic profile with people with autism

Most honey bees are as busy as, well, a bee, tending to the queen and her young, guarding the hive, and generally buzzing and flitting around in near constant motion. But some bees just sit around and rarely interact with their comrades. A new study reveals that these antisocial insects share a genetic profile with people who have autism spectrum disorders, which can affect how well they respond to social situations.

To look for variation in honey bee social behavior, Hagai Shpigler, a postdoctoral fellow at the University of Illinois (UI) in Urbana, designed two tests where he and colleagues video recorded a group of bees and analyzed each individual’s reaction to a social situation. In one test, he stuck an unfamiliar bee in with the group. Bees instinctively “guard” and typically react by mobbing the stranger and sometimes harming it. In the second test, Shpigler put an immature queen larva in with the group. Queen larvae bring out mothering instincts, and worker bees tend to feed the larva. He subjected 245 groups of bees from seven different colonies, 10 bees per group, to these tests multiple times, then ranked how eagerly the bees responded to these situations.

Most bees reacted to at least one situation, but about 14% were unresponsive to both, he and his colleagues report today in the Proceedings of the National Academy of Sciences. The team sacrificed some of the bees and isolated the genes active in the insects’ mushroom bodies, a part of the brain responsible for complex actions such as social behavior. They found a distinctive subset of genes was active in the nonresponsive bees. Then they compared that set of genes to sets of genes implicated in autism spectrum disorder, schizophrenia, and depression. Even though bees and people are very different evolutionarily, they have many genes in common.

There was a good match only between the gene activity of the nonresponsive bees and genes associated with autism, the team reports. Some of the genes involved help regulate the flow of ions in and out of the cells, particularly nerve cells; others code for so-called heat shock proteins that are typically induced during stress.

It’s not clear why these asocial bees are tolerated by the rest of the hive. Rittschof thinks these individuals are considered part of the group despite their unusual behavior. Both human and bee societies “contain and accommodate a range of different personality types, strengths, and weaknesses,” she suggests.
