How common dietary fats can aggravate chronic itch

A team of researchers has found that a breakdown product from a commonly consumed fat can bind to a receptor associated with psoriatic itch and inflammation. By blocking the receptor, the researchers saw a reduction in psoriatic itch in a mouse model. Published in the journal Communications Biology, the work demonstrates the potential impact of diet on chronic itch triggers and could lead to future therapies for both psoriasis and atopic dermatitis.
