Dopaminergic and nitrergic signalling within the PVN are functionally linked, but their cellular relationship remains unclear. We examined the colocalization of dopamine D1 and D2 receptors with neuronal nitric oxide synthase (nNOS) in adult male rats using double\u2010label immunohistochemistry. nNOS\u2010immunoreactive neurons were widely distributed in PVN, with subsets co\u2010expressing D1R or D2R. Approximately 45% of nNOS\u2010positive neurons expressed dopaminergic receptors. These findings provide structural evidence for dopaminergic\u2013nitrergic interaction in the PVN and support the possibility of direct dopaminergic modulation of nitrergic neurons.<\/jats:p>","DOI":"10.1111\/ahe.70134","type":"journal-article","created":{"date-parts":[[2026,5,21]],"date-time":"2026-05-21T13:31:18Z","timestamp":1779370278000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Colocalization
