| Outline of Final Research Achievements |
In animals, osmolality and sodium concentration in body fluids are continuously monitored in the circumventricular organs (CVOs) to keep it. In this study, to figure out the mechanism for the body-fluid homeostasis, we identified the proteins that specifically expressed in CVOs by transcriptome analysis. We also analyzed the expression pattern of Nax, which is known to express in CVOs, in mouse brain. We herein verified that Nax was expressed in neurons in the lateral amygdala of mice, and the interaction between Nax and PSD95 may be involved in promoting the surface expression of Nax channels in neurons.
