Cellular basis of itch sensation.

Sun YG, Zhao ZQ, Meng XL, Yin J, Liu XY, Chen ZF (2009) Cellular basis of itch sensation. Science 325:1531-1534. doi: 10.1126/science.1174868

Summary: Whether itch and pain use separate neuronal pathways has long been a subject of debate. The authors injected 400 ng of bombesin-SAP (Cat. #IT-40) into the intrathecal space of mice and examined itch and pain behavior. Lesioned mice had dramatic deficits in all itch behavior tested regardless of the histamine dependence of the itch. All pain behaviors, however, were left intact. These data indicate that the gastrin-releasing peptide receptor-expressing neurons are essential for itch transmission.
