Effects of lithium on aggression in Drosophila.

ABSTRACT: Lithium is a common medication used to treat mania and bipolar disorder, but the mechanisms by which lithium stabilizes mood and modifies aggression are still not fully understood. Here we found that acute but not chronic lithium significantly suppresses aggression without affecting locomotion in Drosophila melanogaster. Male flies treated with acute lithium are also less competitive than control males in establishing dominance. We also provided evidence that glycogen synthase kinase-3 (GSK-3), a well-known target of lithium, plays an important role in the anti-aggressive effect of lithium in Drosophila. Our genetic data showed that acute knockdown of GSK-3 in neurons can mimic the inhibitory effect of acute lithium on aggression, while specific overexpression of GSK-3 in a subset of P1 ne
