[Cellular immunity in polymorphous light eruption].

Lymphocytic-cell subsets (T total, T helper, T suppressor-cells) have been studied with Monoclonal Antibodies (OKT-3, OKT-4, OKT-8) in 21 patients with Polymorphous light Eruption in inactive phase and have been compared with 13 controls. The results shvon normal cell figures (T total, helper and suppressor). However, when observing the ratio between T helper cells and T suppressor cells, a slight decrease in this ratio is appreciated, which would correspond to a relative increase of suppressor cells. These results are similar to those obtained for the inactive S. L. E. (9).
