Anatomical Organization of Urocortin 3-Synthesizing Neurons and Immunoreactive Terminals in the Central Nervous System of Non-Human Primates [Sapajus spp.]

Abstract: Urocortin 3 (UCN3) is a neuropeptide member of the corticotropin-releasing factor (CRF) peptide family that acts as a selective endogenous ligand for the CRF, subtype 2 (CRF2) receptor. Immunohistochemistry and in situ hybridization data from rodents revealed UCN3-containing neurons in discrete regions of the central nervous system (CNS), such as the medial preoptic nucleus, the rostral perifornical area (PFA), the medial nucleus of the amygdala and the superior paraolivary nucleus. UCN3-immunoreactive (UCN3-i… Show more

“…Among these areas, PeFA Ucn3 projections to AHi showed particularly strong connectivity and high probability of release, and when stimulated lead to overt pup-directed attack behaviors. By contrast, weaker connectivity was identified between PeFA Ucn3 and LS and VMH neurons, which may in part explain the less robust behavioral manifestations of selective activation of PeFA Ucn3 projections to LS and VMH ( Wittmann et al, 2009 ; Chen et al, 2011 ; Battagello et al, 2017 ).…”

“…The function of the AHi is not well understood, although recent data suggest it may send sexually-dimorphic projections to MPOA Gal neurons essential for parenting 11 . LS and VMH projections [49][50][51] appear to play similar roles in the regulation of agonistic interactions with infants. Based on its role in conspecific aggression 32,52 , we hypothesized a role for PeFA Ucn3 to VMH projections in pup-directed attack.…”

“…It should be noted that, in the original description of MCH in a new world monkey, the species has been identified as Cebus apella (Bittencourt et al, 1998). The taxonomic identification of the monkeys used in that experiment has been revised, as those animals are now more closely identified with members of genus Sapajus , and there is some controversy in the precise species definition (for a brief discussion on this subject, see Battagello et al, 2017). In Sapajus spp., MCH neurons are found exclusively in the diencephalon.…”
