Molecular mapping of mouse brain regions innervated by leptin receptor-expressing cells.

ABSTRACT: 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
