Neuronal BST2: A Pruritic Mediator alongside Protease-Activated Receptor 2 in the IL-27–Driven Itch Pathway

In the  present study, RNA-seq were performed To explore biological significance of IL-27 and BST2 in the neuro-cutaneous signaling network of chronic itch. mRNA profiles were generated by deep sequencing, in triplicate, using MGISEQ-2000. We found that both human keratinocytes and murine sensory neurons responded to IL-27 and BST2, resulting in enrichment of genes promoting itch and inflammation. IL-27-BST2 signaling pathway activation promotes cutaneous inflammation and itch, both leading into an aggravation of AD. This finding might help us to better understand the immune-neuro-modulatory mechanism in itch circuits primary human keratinocytes were stimulated with IL-27 (100 ng/ml) or BST2 (250 ng/ml) or vehicle control; primary mouse trigeminal ganglion neurons were stimulated with IL-27 (100 ng/ml) or BST2 (500 ng/ml) or vehicle control. gene expression of these cells were investigated utilizing MGISEQ-2000.
