This research investigates the distribution and coexistence of various neuropeptides in the parvocellular part of the hypothalamic paraventricular nucleus.
Immunohistochemistry was employed to study the distribution of neuropeptides in rat brain tissue.
A double-staining method alongside elution-restaining techniques was utilized to analyze peptide coexistence within neurons.
Approximately 30% of corticotropin-releasing factor neurons also contained neurotensin-like immunoreactivity.
Around 20% of corticotropin-releasing factor neurons showed enkephalin-like immunoreactivity.
About 60% of neurotensin and enkephalin-immunoreactive neurons did not express corticotropin-releasing factor.
