abstract = {Chemogenetics provides cell type-specific remote control of
neuronal activity. Here, we describe the application of
chemogenetics used to specifically activate oxytocin (OT)
neurons as representatives of a unique class of
neuroendocrine cells. We injected recombinant
adeno-associated vectors, driving the stimulatory subunit
hM3Dq of a modified human muscarinic receptor into the rat
hypothalamus to achieve cell type-specific expression in OT
neurons. As chemogenetic activation of OT neurons has not
been reported, we provide systematic analysis of the
temporal dynamics of OT neuronal responses in vivo by
monitoring calcium fluctuations in OT neurons, and
intracerebral as well as peripheral release of OT. We
further provide evidence for the efficiency of chemogenetic
manipulation at behavioral levels, demonstrating that evoked
activation of OT neurons leads to social motivation and
anxiolysis. Altogether, our results will be profitable for
researchers working on the physiology of neuroendocrine
systems, peptidergic modulation of behaviors and
translational psychiatry.},
