Studies have indicated that the alteration of FPR1 function using natural compounds like 3β-hydroxyurs-12,18-dien-28-oic acid (randialic acid B, RAB) and 3β-hydroxyurs-12,19-dien-28-oic acid (tomentosolic acid, TA), has the potential to mitigate in vivo psoriasis-like inflammation [67]. This evidence concerns the gene FPR1 and psoriasis.
