HomeNewsprairie voles oxytocin receptor

NIH Two prairie Voles In fact, prairie voles are teaching us that the genes regulating receptors for oxytocin and vasopressin can be switched off or on across the life cycle. While OXTR in a few regions, such as the nucleus accumbnes (NAcc), prefrontal cortex (PFC) and anterior cingulate cortex (ACC), have been implicated in regulating these behaviors, the extent to which other OXT sensitive areas modulate social behaviors … Epub 2018 Nov 29. Ogi A, Mariti C, Baragli P, Sergi V, Gazzano A. They found that blocking the prairie voles’s oxytocin receptors with the antagonist had no effect in mating-induced aggression and partner preference over other new potential mates (they still exhibited pair-bonding). Fos; Functional connectivity; Functional coupling; Immediate early gene; Nucleus accumbens; Pair bonding network; Sexual behavior; Social behavior; Social behavior network; Social decision making network; Striatum. Variation in oxytocin receptor density in the nucleus accumbens has differential effects on affiliative behaviors in monogamous and polygamous voles. This site needs JavaScript to work properly. We hypothesized that oxytocin receptor in the nucleus accumbens facilitates the expression of "spontaneous" maternal behavior in prairie voles. Leonzino M, Ponzoni L, Braida D, Gigliucci V, Busnelli M, Ceresini I, Duque-Wilckens N, Nishimori K, Trainor BC, Sala M, Chini B. Horm Behav. From adolescence to late aging: A comprehensive review of social behavior, alcohol, and neuroinflammation across the lifespan. J Neurosci. For example, oxytocin (OT) is an ancient neuropeptide that binds to OT receptors (OTRs) in the brain and modulates social and reproductive behavior across vertebrate species, including humans. Get the latest public health information from CDC: https://www.coronavirus.gov. Jason Yee, a postdoctoral fellow at Sue Carter’s lab at the University of Illinois at Chicago, suggests that oxytocin could be having an effect by switching a brain pathway from stress-inducing to calming. Pathogens, odors, and disgust in rodents. Sci Rep. 2020 Oct 14;10(1):17301. doi: 10.1038/s41598-020-74243-1. Here we describe the efficient generation of oxytocin receptor (Oxtr) mutant prairie voles (Microtus ochrogaster) using the CRISPR/Cas9 system, and describe initial behavioral phenotyping focusing on behaviors relevant to autism. This suggests that oxytocin is important for the emergence of helping behavior. Clipboard, Search History, and several other advanced features are temporarily unavailable. 1B shows a schematic of the experimental timeline and design (D = day; m = male; f = female). Oxtr mutant male voles show no disruption in pup ultrasonic vocalization, anxiety as measured by the open field test, alloparental behavior, or sociability in the three chamber test. Variation in the organization of neuropeptide systems across these networks is thought to contribute to individual and species diversity in network function during social contexts. 1997 Jun;31(3):221-31. doi: 10.1006/hbeh.1997.1377. Here we describe the efficient generation of oxytocin receptor (Oxtr) mutant prairie voles (Microtus ochrogaster) using the CRISPR/Cas9 system, and describe initial behavioral phenotyping focusing on behaviors relevant to autism. Oxtr Δ60/Δ60 prairie voles showed a complete absence of OXTR binding in brain. Mitre M, Kranz TM, Marlin BJ, Schiavo JK, Erdjument-Bromage H, Zhang X, Minder J, Neubert TA, Hackett TA, Chao MV, Froemke RC. Construction of sgRNAs targeting the prairie vole oxytocin receptor gene ( Oxtr ).…, Generation of Oxtr gene modified prairie voles by CRISPR/Cas. 2020 Aug;124:104780. doi: 10.1016/j.yhbeh.2020.104780. Neuroscience. What’s more, the effects of the injection lasted long after the initial dose had worn off. The ability to efficiently generate targeted mutations in the prairie vole genome will greatly expand the utility of this model organism for discovering the genetic and circuit mechanisms underlying complex social behaviors, and serves as a proof of principle for expanding this approach to other non-traditional model organisms. Hayashi R, Kasahara Y, Hidema S, Fukumitsu S, Nakagawa K, Nishimori K. Front Endocrinol (Lausanne). ( A ) Picture…, Evidence for functional abnormality of OXTR in Oxtr Δ60/Δ60 voles. 2016 Jan;77:132-40. doi: 10.1016/j.yhbeh.2015.04.006. Abstract. However, male prairie voles injected with the vasopressin antagonist failed to exhibit aggression to defend the female partner, and did not spend as much time with the original mate as … Horm Behav. The prairie vole is special for having pair bonding with its partner. Site-specific administration of OTA into…, Site-specific administration of OTA into the NAc has no effect on male sociosexual…, Effects of mating and accumbal OTR signaling on Fos-ir across the SSN. World Psychiatry. Some of these are credible, such as studies that show that people trust others more after they sniff the hormone. However, in recent years the ability to manipulate the genomes of laboratory strains of mice has led to rapid advances in our understanding of the role of specific genes, circuits and neural populations in regulating behavior. NLM HHS Please enable it to take advantage of the complete set of features! Another prairie vole study presented at the meeting shows that, in combination with social interaction, oxytocin can lower anxiety-related behaviors in frightened animals. Using a selective OTR antagonist, we test whether activation of OTRs in the NAc during sociosexual interaction and mating modulates expression of the immediate early gene product Fos across nuclei of the SSN. Although oxytocin therapies are promising for treating aspects of social behavior, she says, they may not directly address the issues that are specific to autism. Behavioral neuroendocrinology has benefited tremendously from the use of a wide range of model organisms that are ideally suited for particular questions. SPS enhanced fear learning in prairie voles cohabited with same sex partner. USA.gov. No differences were found in other brain regions (medial preoptic area, septum, prelimbic cortex). Oxytocin and vasopressin neural networks: Implications for social behavioral diversity and translational neuroscience. eCollection 2020. Females that showed maternal behavior (lick and groom the pups and hover over them for at least 30 s, n=24) had higher oxytocin receptor density in the nucleus accumbens (shell subregion) (P<0.05) than females that did not show maternal behavior or attacked the pups (n=16).
