Researchers have identified significant differences in the mechanisms of chronic itch between hairy and non-hairy areas of the skin.
A new case study reveals medical marijuana may provide rapid relief for sufferers of chronic itch. Researchers say THC attaches itself to brain receptors that influence the nervous system. This reduces inflammation and nervous system activity, leading to a reduction in itch sensation.
Those with eczema who produce immunoglobulin E in response to environmental allergens are more likely to experience chronic and acute itching.
Researchers identified a set of neurons in the spinal cord that transmits a light-touch signal from the skin to the brain. NPY-Y1 signaling regulates the transmission of innocuous tactile information by establishing thresholds for touch discrimination and mechanical itch reflexes. The findings shed new light on the neurobiological basis of chronic itching.
Researchers implicate the neuropeptide NPPB in generating the itching sensation symptomatic of eczema.
