Basomedial hypothalamic injections of neuropeptide Y conjugated to saporin selectively disrupt hypothalamic controls of food intake.

Bugarith K, Dinh TT, Li AJ, Speth RC, Ritter S (2005) Basomedial hypothalamic injections of neuropeptide Y conjugated to saporin selectively disrupt hypothalamic controls of food intake. Endocrinology 146(3):1179-1191. doi: 10.1210/en.2004-1166

Summary: The authors examined the effect of 48 ng injections of NPY-SAP (Cat. #IT-28) into the basomedial hypothalamus (BMH) on glucoprivic feeding in rats. While there was no evidence of retrograde transport, the lesions inhibited responses to intracerebroventricular leptin and ghrelin. Neither the feeding nor the hyperglycemic response to 2-deoxy-D-glucose was affected by the lesion, indicating that these hindbrain processes do not utilize neurons in the BMH. This work also describes dosing and injection parameter studies for the use of NPY-SAP.
