Common_Namecis-Urocanic acid
Description"Urocanic acid (UCA) is present at millimolar concentrations in mammalian epidermis and undergoes photoisomerization from the naturally occurring trans-isomer to the cis-isomer on exposure to ultraviolet radiation (UVR). Cis-UCA causes downregulation of various immune responses in mouse and human experimental models and has been proposed as both a chromophore and a mediator of UV-induced immune suppression" (McCloone et. al., Journal of Investigative Dermatology, 124(5):1071-1074 (2005);
