Abstract

Leptin plays an important role in the control of food intake and energy metabolism by interacting with its receptor (OB-R) in the brain. Several alternatively spliced isoforms of OB-R have been identified. To study the expression patterns and the potential biological function of these OB-Rs in the brain, the distribution of mRNA encoding OB-R isoforms was examined by in situ hybridization. In agreement with previous studies, strong signals for OB-R mRNA were detected in the hypothalamus, thalamus and choroid plexus. In addition, intense signals were observed in several other brain areas including piriform cortex, granule cell layer of the cerebellum and substantia nigra. With isoform-specific probes, a differential expression pattern of OB-Rs was revealed: OB-Ra and OB-Rb, but not OB-Rc and OB-Rf, are abundantly expressed in the hypothalamus, whereas OB-Ra, OB-Rc and OB-Rf, but not OB-Rb, are significantly expressed in the choroid plexus. The preferential expression of OB-Rb in the hypothalamus is in support of its role in mediating the satiety effect of leptin. The co-expression of OB-Ra with OB-Rb in the hypothalamus may suggest a possible interaction between the two isoforms. Finally, the detection of OB-R mRNA in a number of other brain regions may indicate the involvement of leptin in additional as yet undefined physiological functions.

  • Leptin may modulate sensory processing at higher gustatory and olfactory processing steps, as indicated by the presence of leptin receptors and leptin-induced Fos expression in the nucleus of the solitary tract, parabrachial nucleus, olfactory bulb, and insular and piriform cortices of rodents.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
