title: Paraventricular nucleus neurons producing neurotensin after lipopolysaccharide treatment project to the median eminence.
abstract: Inflammation consists in secretion of cytokines that stimulate the hypothalamo-pituitary-adrenal (HPA) axis to release the anti-inflammatory corticosterone. Upstream in this axis are corticotropin-releasing hormone (CRH) neurons in the paraventricular nucleus (PVN) whose multipeptidergic phenotype changes: both corticotropin-releasing hormone mRNAs and neurotensin mRNAs are up-regulated. Combining in situ hybridization with a retrograde neuronal marker, we demonstrated that neurotensin-containing neurons in the paraventricular nucleus project to the median eminence.
