To study the possible immunomodulatory effects of cis-UCA, the two isomers were added separately to different in vitro assays employing human epidermal cell suspensions or purified human peripheral T lymphocytes, supplemented with epidermal cells. Cis-UCA but not trans-UCA suppressed interleukin-1 (IL-1) production by epidermal cell suspensions in a dose-dependent fashion and diminished the number of HLA-DR positive epidermal cells to 61% of control values. An inhibitory effect on epidermal cell accessory function could be demonstrated with both isomers of UCA, but only if UVB-irradiated epidermis was used as a source for the epidermal cells.
