A new study of male mice published in JNeurosci uncovers two distinct pathways through which a single molecule can cause both itchy and painful skin. The research could inform the development of drugs for a variety of skin diseases.
Diana Bautista and colleagues show that sphingosine 1-phosphate (S1P) -- a molecule implicated in skin conditions such as psoriasis as well as other inflammatory diseases including asthma and multiple sclerosis -- triggers itch in addition to its known role in pain. Their work identifies a receptor of this molecule, S1PR3, expressed in sensory neurons is responsible for these sensations. The findings suggest that blocking this receptor may represent a promising therapeutic approach for managing both pain and itch.

JNeurosci, the Society for Neuroscience's first journal, was launched in 1981 as a means to communicate the findings of the highest quality neuroscience research to the growing field. Today, the journal remains committed to publishing cutting-edge neuroscience that will have an immediate and lasting scientific impact, while responding to authors' changing publishing needs, representing breadth of the field and diversity in authorship.
