Researchers investigated the effects of a plant extract and its component on itch-related processes in the central nervous system. They found that the extract and component suppressed itch-related cytokines in microglia, potentially offering relief for pruritus.
The study focuses on the potential use of the plant extract and its main component, myricetin, in alleviating histamine-independent pruritus (itching). By evaluating the effects on signal transducer and activator of transcription 3 (STAT3) activation, glial fibrillary acidic protein (GFAP) expression, and lipocalin-2 (LCN2) production in astrocytes, as well as scratching behavior, mast cell infiltration, and IL-6 levels in mice, the researchers found that the extract and myricetin inhibited STAT3 activation, GFAP expression, and LCN2 release in astrocytes. Moreover, they also ameliorated scratching behavior and other allergic responses in mice. These findings suggest that the plant extract and myricetin could be potential therapeutic agents for the treatment of pruritus.
