Pheromones regulate aggression of non-mother female mice toward pups in wild-derived mice
Date:8/5/2014

ive behavior displayed toward them. A pup's mother, it turns out, is the one and only, and stepmothers, naturally, are more aggressive toward others' offspring. Their findings, published in the journal Nature Communications, provide the basis for developing additional mouse strains that will enable a better understanding of the neural and genetic basis of behavior relating to reproduction in females, and the differences between males and females.

Kimchi hopes that further research will lead, in the future, to a renewed understanding of the biological mechanisms underlying social and reproductive processes that have not been possible to explore in standard models of lab mice until now. It may also lead to a better understanding of the social component of neuropsychiatric diseases, which is manifested in different ways in men and women. Such knowledge will contribute to improving the development of drugs targeted to the different sexes, and in particular, will enable an analysis of the effect of certain drugs on women.
