Fig. 2From: Suppression of experimental autoimmune encephalomyelitis by ultraviolet light is not mediated by isomerization of urocanic acidUVB increases cis-UCA skin content and efficiently suppresses EAE. a UVB significantly increased skin cis-UCA content (P < 0.0001) through conversion of the trans isomer (b). c UVB suppresses the onset (P = 0.006) and progression of EAE (P < 0.0001). Data are cumulative of two independent experimentsBack to article page
