Resolvin D3 controls mouse and human nociceptive functions and preclinical progression of psoriasis

Psoriasis is a chronic inflammatory skin disease caused by a complex interplay between the immune and nervous systems. Here, we found that resolvin D3 (RvD3) significantly prevented both skin inflammation and itch in a preclinical animal model of psoriasis induced by repeated applications of imiquimod. We also found that RvD3 anti-psoriatic effects resulted from the inhibition of nociceptive functions, which inhibition was replicated in human nociceptive neurons. We conclude that RvD3 and targeting nociceptive functions are promising strategies to treat psoriasis.
