MCT2 is localized in orexigenic neurons of the arcuate nucleus.

<p>(a–c) Low magnification images of the ventro-medial hypothalamus, analyzed by immunohistochemistry using anti-AgRP (red) and anti-NPY (blue) antibodies. Ventricular arcuate nucleus neurons co-express AgRP and NPY (c). (d) Scheme summarizing the localization of the orexigenic neuropeptides in the AN. (e–l) High magnification images showing the dorsal (e–h) and ventral (i–l) region of the ventricular AN. An intense MCT2 immunoreaction was detected in orexigenic neuronal bodies in both areas (insets h and l). AN: arcuate nucleus, IIIV: third ventricle, ME: median eminence, PT: <i>pars tuberalis</i>. Scale bars: (a–c) 150 µm; (e–l) 50 µm.
