Abstract
We have previously shown that peroxisome proliferator activating receptor ß/d (PPAR b/d is overexpressed in psoriasis.
PPAR b/d is not present in adult epidermis of mice. Targeted expression of PPAR b/d and activation by a selective synthetic
agonist is sufficient to induce an inflammatory skin disease resembling psoriasis. Several signalling pathways dysregulated
in psoriasis are replicated in this model, suggesting that PPAR b/d activation contributes to psoriasis pathogenesis. Thus,
inhibition of PPAR b/d might harbour therapeutical potential. Since PPAR b/d has pleiotropic functions in metabolism, skin-
targeted inhibition offer the potential of reducing systemic adverse effects. Here, we report that three selective PPAR b/
d antagonists, GSK0660, compound 3 h, and GSK3787 can be formulated for topical application to the skin and that their
skin concentration can be accurately quantified using
