Abstract/Results: | ABSTRACT:
Oxytocin-like neurohormones (isotocin in fish, mesotocin in birds, reptiles and amphibian, and oxytocin in mammals) have been implicated in the regulation of social behavior across vertebrates (Goodson and Thomson, 2010). Although vasopressin is more involved in aggression behavior while oxytocin in pro-social behaviors, these neuropeptides and receptor subtypes are similar (Chini et al, 2007), and so, most of the classical pharmacological evidences do not differentiate their specific contribution on social behaviors. We took advantage of the zebrafish model, a simpler-minded, but still a highly social animal model with a well-characterized repertoire of social behaviors and a wide genetic toolbox available, to investigate the role of the oxytocin-like family on social behavior. For this purpose, we developed genetic tools to manipulate the oxytocinergic neuronal circuits and to study how the loss of function of these neurons during embryonic development, or throughout the organism´s lifetime, modifies the development of social behaviors in this species. We have collected evidences that support the role of the oxytocinergic neurons in the acquirement of zebrafish sociality, a trait that emerges during the third week of development. A conditional (i.e. temporal) and cell-specific ablation (through GAL4/UAS-Nitroreductase system) of these neurons at a critical developmental time window, but not during adulthood, significantly altered specific adult social behaviors in zebrafish. Furthermore, using genome editing methods (i.e. TALEN, CRISPR), we characterized the contribution of the oxytocinergic signaling players on the development of specific aspects of social behavior. Our findings suggest that the oxytocin-like neuronal system is involved on sociality that becomes hardwired during early development. Furthermore, our data support that oxytocinergic neurons may modulate distinct aspects of social behaviors through different mechanisms.
