(A) Darkfield photomicrograph showing the injection site (green circle) of an adenoviral vector encoding Cre-regulated expression of farnesylated green fluorescent protein (GFPf) delivered into the VMH of a CRFR2-Cre mouse. The expression of GFPf is normally silenced due to a Cre-regulated transcription block sequence inserted upstream of GFPf reporter cassette. In the presence of Cre, the transcription block sequence is removed to allow GFPf to be expressed in Cre-positive cells. (B) Darkfield photomicrograph depicting the distribution of VMH CRFR2-positive fibers (golden staining) within the rostral ventrolateral medulla (RVLM). ARH, arcuate nucleus of hypothalamus; MARN, magnocellular reticular nucleus; ME, median eminence; Py, pyramidal tract; Tu, tuberal nucleus; V3, third ventricle; VII, facial nucleus; VMHdn, dorsomedial part of the ventromedial nucleus of hypothalamus. Scale bar = 50 μm.
