A neuron found in the spinal cords of mice could be responsible for sending itch messages to the brain. It likely works the same in humans. The finding could lead to treatments for serious human itches. Image credit: stockxpertFrom Live Science:
The urge to scratch a mosquito bite or skin rash can be maddening. Now, scientists have pinpointed a group of neurons that signal it's time to relieve the itch.
Disabling the neurons eliminated itching in mice, which are thought to be a good analogue to humans for neurobiology studies.
The work could pave the way for treatment of serious human itches, such as psoriasis and eczema, said study scientist Zhou-Feng Chen of Washington University School of Medicine in St. Louis.
