Outline of Final Research Achievements |
The purpose of the study was to investigate novel osmo-/mechano-sensing molecules and osmosensitive mechanisms in the central nervous system, including the hypothalamo-neurohypophysial system. We visualized the central osmosensitive areas after acute osmotic challenge, using c-fos-eGFP transgenic rats that express c-fos and eGFP fusion gene after adequate physiological stimuli. We found that osomotic and non-osmotic stimuli such as mechanical and hypovolemic stimuli caused activation of vasopressin-eGFP magnocellular neurosecretory cells in vasopressin-eGFP transgenic rats. We also found that TRPV1 and TRPV4 knockout mice showed different drinking behaviors in comparison with wild type.
