Topiramate, an antiepileptic drug, has been found to be useful for the treatment of aggression in clinical populations as well as in animal models of aggression. However, increases in aggression were also observed under lower doses of Topiramate. Subsequently, Topiramate produced an inverted U-shaped dose response curve, with increases in aggression at low doses, whereas higher doses engendered anti-aggressive effects. In our previous study, we demonstrated that Topiramate modulates brain activity in the prefrontal areas involved in the modulation of the subcortical circuit mediating aggression, and we found indirect evidence that the anterior cingulate cortex (ACC) could be a key site where Topiramate may exert its dose-response effects on aggression. In this study, we performed site-directed injections of Topiramate (0.1 and 0.3 mM) into the ACC on offensive behaviors in isolation-inducedaggression paradigm. By using the resident-intruder test, we demonstrated that Topiramate microinfusion into the ACC at low doses produced increases in aggression, as evidenced by shorter attack latencies (p  less then  0.01) and increased attack duration (p  less then  0.01), without affecting the social behavior. In contrast, higher doses engendered anti-aggressive effects, by increasing the attack latencies (p  less then  0.001), decreasing attack number (p  less then  0.001) and decreasing attack duration (p  less then  0.001), as well as an increase in the social behavior. Our findings supported that Topiramate at higher concentrations appeared more efficient to decrease aggression in treated mice. Therefore, we suggest that the ACC is a key brain region in which Topiramate may exert its dose-response effects on aggressive and antisocial behaviors observed in populations with psychotic disorders.Relaxin family peptide receptor 3 (RXFP3) is a G protein-coupled receptor implicated in the regulation of food intake and stress response upon activation by the neuropeptide relaxin-3. In recent studies, interactions of RXFP3 with some natural or synthetic ligands have been investigated. In the present study, we identified the hydrophobic interactions of human RXFP3 with the chimeric agonist R3/I5 and the chimeric antagonist R3(ΔB23-27)R/I5 using a newly developed NanoBiT-based homogenous binding assay. We first demonstrated that the conserved large aliphatic B15Ile and B19Ile were important for the binding of the agonist and antagonist to RXFP3, because alanine replacement significantly decreased their receptor-binding potency. Thereafter, we demonstrated that the conserved large aliphatic Leu246 and Leu248 in extracellular loop 2 were important for RXFP3 binding to the agonist and antagonist, because alanine replacement significantly decreased the binding affinity of RXFP3 for both ligands. Finally, we deduced probable hydrophobic interactions based on the ability of RXFP3 mutants to distinguish the wild-type and mutant ligands Leu246 of RXFP3 interacted with B15Ile of both ligands, while Leu248 of RXFP3 interacted with both B15Ile and B19Ile of the agonist and antagonist. The present results not only provided new insights into the interaction mechanism of RXFP3 with agonists and antagonists, but also demonstrated usefulness of the NanoBiT-based homogenous binding assay to study the interaction mechanism of certain receptors with their ligands.Terror management theory proposes cultural worldview and self-esteem as two buffers against death anxiety. The neural mediators of these buffering effects, however, have not been fully understood. The present work investigated neural mediation mechanisms between self-esteem/cultural trait (self-construal) and mortality salience (MS) effects on self-face processing. We found that MS (vs. NA) priming eliminated self-face advantage in behavioral judgments of face-orientation in low self-esteem individuals and reduced self-face advantage in behavioral judgments of facial-familiarity in individuals with high interdependent self-construals. Our functional magnetic resonance imaging (fMRI) results showed that, following MS priming, insular activities mediated the relationship between self-esteem and self-face advantage in face-orientation judgments, whereas dorsal medial prefrontal activity mediated the relationship between interdependent self-construal and self-face advantage in face-familiarity judgments. Our findings suggest that distinct neural mechanisms are engaged in mediating the relationships between self-esteem/cultural trait and MS effects on the emotional and cognitive processes of self-relevant information.Microalgae have many commercial applications including biofuel production, use in human and animal nutrition, as pharmaceuticals and therapeutic compounds, in beauty-related products and as biofertilizers in the agricultural sector. However, more research needs to be directed to reducing production costs in an environmentally friendly way before their commercial potential can be fully realized. This review discusses the current knowledge on the occurrence and physiological roles of phytohormones in microalgae and explores the potential of phytohormone treatments to improve cultivation practices, including increasing lipid content and productivity for biofuel production. Microalgae synthesize a wide array of phytohormones and are able to regulate the levels of active phytohormones. Biosynthetic and conversion pathways share some key components but are more rudimentary compared to vascular plants and are likely to have some unidentified conjugation mechanisms. Phytohormones have a dual function in microalgae. Specific phytohormones are involved in the regulation of the cell cycle and other metabolic processes, influencing biomass and primary metabolite accumulation. They are also involved in responses to abiotic stresses, allowing microalgae to adapt to the prevailing conditions. selleck inhibitor Phytohormones provide a promising strategy to improve mass culture biotechnology due to their intrinsic role in microalgal growth and survival, increasing lipid productivity and improving their tolerance to more extreme environmental changes. This makes them less susceptible to environmental fluctuations. This improves the productivity of the cultures for biofuel production and would be beneficial in a biorefinery approach. Overall, phytohormones provide an exciting and promising avenue of research to improve microalgae cultivation, taking it a step closer to successful commercialization.
