| Outline of Final Research Achievements |
Many neuropeptides activate arginine vasopressin (VP) neurons in the hypothalamic supraoptic (SON) and the paraventricular nuclei (PVN) and release VP into the systemic circulation. In olfactory bulb (OB), VP is related to regulate with social behavior. In present study, I examined the effects of intracerebroventricular (icv) injection of some neuropeptides, including ghrelin and adrenomedulline family, by immunohistochemistry for Fos in OB. Fos-like immunoreactivity (Fos-LI) was observed in the SON, PVN and the nucleus of the tractus solitaries such as previous studies. However, few Fos-LI were observed in the OB. After icv injection of colchicine in VP-enhanced green fluorescent protein (eGFP) transgenic rats, fluorescence of eGFP did not change in the OB in comparison with control rats. I suggested that VP synthesis in the SON and PVN, not OB, project into OB, and have physiological effects in OB.
