Neuropeptide Y conjugated to saporin alters anxiety-like behavior when injected into the central nucleus of the amygdala or basomedial hypothalamus in BALB/cJ mice.

Lyons AM, Thiele TE (2010) Neuropeptide Y conjugated to saporin alters anxiety-like behavior when injected into the central nucleus of the amygdala or basomedial hypothalamus in BALB/cJ mice. Peptides 31(12):2193-2199. doi: 10.1016/j.peptides.2010.09.009

Summary: Neuropeptide Y (NPY) in the hypothalamus is known to modulate feeding behavior. In this work the authors used bilateral 48 ng injections of NPY-SAP (Cat. #IT-28) into the central amygdala or basomedial hypothalamus (BMH) of rats to investigate the role of NPY in anxiety. Blank-SAP (Cat. #IT-21) was used as a control. Injections into the amygdala increased anxiety-like behavior, while injections into the BMH reduced anxiety-like behavior. BMH injections also initiated an increase of NPY-1 receptor expression in the basolateral nuclei of the amygdala.
