Summary: Our study demonstrated differential expression of arginine vasotocin (avt) and isotocin (it) in the brain and pituitary of black porgy during osmotic stress. These findings suggest the involvement of neurohypophysial hormones in the response to osmotic stress.

Summary: Recent studies have found that exposure to bisphenol S (BPS) can have multiple adverse effects on organisms. This study exposed adult female zebrafish to environmentally relevant concentrations of BPS and found that maternal exposure affected the social behavior and anxiety response of male offspring in a dose-specific manner. The impaired social behavior was associated with changes in neuropeptide signaling pathways in the brain.

Summary: The study shows that the nonapeptide systems in electric fish have a common general organization, but subtle differences compared to other teleost species. It also reveals that IT and AVT neurons are intermingled in the preoptic area, but have different effects on basal electric signaling.

Summary: This article critically reviews the current knowledge of the roles of nonapeptide systems in teleost reproduction, focusing on the roles of arginine vasopressin (AVP) and oxytocin (OXT) in reproductive behavior and the regulation of the hypothalamic-pituitary-gonadal axis. The article also highlights the importance of a gonadal nonapeptide system in steroidogenesis and gamete maturation, and calls for translational studies linking this knowledge to aquaculture, conservation biology, and ecotoxicology.

Summary: The objective of this study was to evaluate the effect of visual isolation and oxytocin on the aggressive behavior of male Betta splendens. The results showed that visual isolation had no effect on aggression, while exposure to oxytocin reduced the frequency of aggressive behavior.

Summary: This study provides a parsimonious explanation for the origin of the OTR/VTR gene family, based on phylogenetic and chromosomal conserved synteny analyses. The findings suggest a chromosome quadruplication event associated with whole-genome duplications early in vertebrate evolution, prior to the radiation of jawed vertebrates. The evolution of the OTR/VTR gene family can be explained by two whole-genome duplications followed by differential gene losses of VTR2 genes in different lineages.

Summary: AVP neurons in the medial preoptic (MPO) area release GABA and display thermosensitive firing activity. Optogenetic stimulation results in a decrease of the firing rates of PACAP neurons, and AVP modulates the synaptic inputs of PACAP neurons by activating neuronal and astrocytic receptors. Chemogenetic activation of AVP neurons induces hyperthermia and also decreases fever and stress-induced hyperthermia.

Summary: This study reveals the impact of social isolation on the oxytocinergic circuit in the zebrafish brain and how chemical signals from conspecific animals modulate this circuit. The results provide a model for understanding how social stimuli mediate adaptive behaviors through neural circuits.

Summary: 'Urban adapter' species in urban habitats often display higher aggression towards conspecifics, and this behavior could be regulated by the neuroendocrine system. In this study, it was found that urban male song sparrows had a higher proportion of activated AVT neurons compared to rural males, regardless of the duration of social challenge. These findings suggest that the AVT system plays a role in regulating behavioral responses to urbanization.

Summary: Recent data suggests that patients with diabetes insipidus (DI) are being harmed. The authors propose renaming central and nephrogenic DI as arginine vasopressin deficiency and resistance, respectively.

Summary: This study establishes a model of enhanced aggression in virgin female rats and shows that oxytocin and vasopressin systems differentially modulate aggression in distinct neuronal populations of the lateral septum of female rats.

Summary: Social interactions are essential for mammalian life and are regulated by the lateral septum (LS), a neuroanatomical structure that integrates and projects information to influence behavioral responses. Incoming cognitive information and neuromodulatory information related to the internal state of the organism determine the outcome of social behavior.

Summary: This study investigated the effects of AVP on membrane potential responses of temperature-sensitive and -insensitive POA neurons. The results showed that AVP enhanced the membrane potential thermosensitivity of nearly 50% of the temperature-insensitive neurons, while there was no difference in the effects on membrane potential of temperature-sensitive neurons. Furthermore, AVP induction did not result in any changes in resting potential of POA neurons.

Summary: Research shows that in agonistic interactions, dominant rainbow trout exhibit higher aggression and feeding levels, while subordinate fish show upregulation of AVT receptors, CRF mRNA, and cortisol levels.
