Abstract Kisspeptinergic signaling is well‐established as crucial for the regulation of reproduction, but its potential broader role in brain function less understood. This study investigates distribution and chemotyping kisspeptin‐expressing neurons within mouse brain. RNAscope single, dual, multiplex situ hybridization methods were used to assess kisspeptin mRNA ( Kiss1 ) expression co‐expression with other neuropeptides, excitatory inhibitory neurotransmitter markers, sex steroid receptors wild‐type intact gonadectomized young adult mice. Seven distinct neuronal chemotypes characterized, including two novel groups described first time, that is, population ventral premammillary nucleus solitary tract. was also observed localize both somatic dendritic compartments hypothalamic neurons.

Abstract In humans, traumatic social experiences can contribute to psychiatric disorders 1 . It is suggested that trauma impairs brain reward function such behaviour no longer rewarding, leading severe avoidance 2,3 rodents, the chronic defeat stress (CSDS) model has been used understand neurobiology underlying susceptibility versus resilience following trauma, yet little known regarding its impact on 4,5 Here we show that, CSDS, a subset of male and female mice, termed susceptible (SUS), avoid interaction with non-aggressive, same-sex juvenile C57BL/6J mice do not develop context-dependent encounters them. Non-social stressors have effect in either sex. Next, using whole-brain Fos mapping, vivo Ca 2+ imaging whole-cell recordings, identified population stress/threat-responsive lateral septum neurotensin (NT LS ) neurons are activated by interactions only SUS but resilient or unstressed control mice. Optogenetic chemogenetic manipulation NT their downstream connections modulates reward. Together, these data suggest previously rewarding targets possibly perceived as threats resulting from hyperactive occlude processing.

The lateral septum (LS) is a midline, subcortical structure that critical regulator of social behaviors. Mouse studies have identified molecularly distinct neuronal populations within the LS, which control specific facets behavior. Despite its known molecular heterogeneity in mouse and role regulating behavior, comprehensive profiling human LS has not been performed. Here, we conducted single-nucleus RNA sequencing (snRNA-seq) to generate transcriptomic profiles compared recently collected snRNA-seq datasets. Our analyses TRPC4 as conserved marker while FREM2 enriched only LS. We also identify cell type marked by OPRM1, gene encoding μ-opioid receptor.
