The adipose tissue-derived hormone leptin regulates body weight
homeostasis by decreasing food intake and increasing energy expenditure. The weight-reducing action of leptin is thought to be
mediated primarily by signal transduction through the leptin receptor
(LR) in the hypothalamus. We have used immunohistochemistry to localize
LR-immunoreactive (LR-IR) cells in the rat brain using an antiserum
against a portion of the intracellular domain of LR that is common to
all LR isoforms. The antiserum recognized the short and long isoforms
of LR in transfected hematopoietic BaF3 cells. To examine the chemical
nature of target cells for leptin, direct double-labeling
immunofluorescence histochemistry was applied. The results show
extensive distribution of LR-like immunoreactivity (LR-LI) in the brain
with positively stained cells present, e.g., in the choroid plexus,
cerebral cortex, hippocampus, thalamus, and hypothalamus. In the
hypothalamus, strongly LR-IR neurons were present in the supraoptic
nucleus (SON) and paraventricular nucleus (PVN), periventricular
nucleus, arcuate nucleus, and lateral hypothalamus. Weaker LR-IR
neurons were also demonstrated in the lateral and medial preoptic
nuclei, suprachiasmatic nucleus, ventromedial and dorsomedial nuclei,
and tuberomammillary nucleus. Confocal laser scanning microscopy showed
LR-LI in the periphery of individual cells. In magnocellular neurons of
the SON and PVN, LR-LI was demonstrated in vasopressin- and
oxytocin-containing neurons. In parvocellular neurons of the PVN, LR-LI
was demonstrated in many corticotropin-releasing hormone-containing
neurons. LR-IR neurons were mainly seen in the ventromedial aspect of
the arcuate nucleus, where LR-LI co-localized with neuropeptide Y. In
the ventrolateral part of the arcuate nucleus, LR-LI was present in many large adrenocorticotropic hormone-IR
proopiomelanocortin-containing neurons and in a few galanin-,
neurotensin-, and growth hormone-releasing hormone-containing neurons.
In the dorsomedial arcuate nucleus, few tyrosine hydroxylase
(dopamine)-containing neurons were seen to have LR-LI.
Melanin-concentrating hormone-containing neurons in the lateral
hypothalamus had LR-LI. Based on the immunohistochemical results,
possible interactions of leptin with brain mechanisms are
discussed.
