The gut microbiome in Prader-Willi syndrome


Prader-Willi syndrome individuals show impaired social behaviors and altered oxytocin levels in the brain, but the reason for this remains unknown. Here we will test whether changes in the gut bacterial content in PWS could perturb social behaviors and related changes in oxytocin. In addition, we will examine whether a probiotic bacteria strain that promotes reverses social behaviors in a mouse model of PWS.
