Scientists find nerve cells responsible for itch
Washington, August 10: Researchers have found specific nerve cells responsible for itchiness, a discovery that could lead to better treatments for skin conditions.
Experiments on mice show they have nerve cells that convey only an itch sensation — contradicting common wisdom that itch and pain are closely related.
Reporting in the journal Science, researchers at Washington University School of Medicine in St. Louis and Peking University Third Hospital in Beijing said they created itch-free mice by killing their itch-specific neurons.
