Leptin acts via the long form of the leptin receptor (LepRb) on specialized sets of neurons in the brain to modulate diverse functions in concert with energy stores. Previous studies have revealed the distribution of LepRb-expressing neurons in the brain but not the regions to which LepRb neurons project to mediate downstream leptin actions. We utilized LepRb-cre in combination with cre-inducible enhanced green fluorescent protein (EGFP) and farnesylated EGFP (EGFPf) mouse reporter strains to visualize LepRb neurons and their projections, respectively, throughout the brain. The areas containing LepRb soma and projections were relatively circumscribed, as many brain regions contained no detectable EGFP or EGFPf. The highest concentrations of LepRb neurons and LepRb projections were found in the hypothalamus, where the ventral premamillary (PMv), dorsomedial (DMH), and arcuate (ARC) nuclei contained the greatest number of cell bodies, in addition to substantial EGFPf-reactivity. Furthermore, both LepRb soma and projections were present in a few midbrain and brainstem nuclei. Several brain regions including the hypothalamic paraventricular nucleus (PVH), the anteroventral periventricular nucleus (AVPe), and the central nucleus of the amygdala (CeA) contained few LepRb neurons but substantial EGFPf, suggesting that these regions represent targets of LepRb neurons that lie elsewhere in the brain. In some nuclei that contained both soma and projections, the distribution of soma and projections differed, suggesting that these areas transmit leptin-encoded information in a neuroanatomically directional manner.
