title: Flow cytometric analysis of murine splenic cells after DNFB painting on Langerhans cell deficient skin.
abstract: One week after a single painting of 50 microliters of 0.5% DNFB in acetone-olive oil on the tail skin of C3H mice, the spleens were removed from the animals. A single cell suspension was prepared from the spleens, and flow cytometric analysis was performed for L3T4 and Lyt2 positive cells, as well as for the IJk expression of the Lyt2+ cells. Results showed that the percentages and absolute numbers of Lyt2+ L3T4- cells, Lyt2- L3T4+ cells, Lyt2+ IJk+ cells, and Lyt2+ IJk- cells in the spleens of the DNFB-treated mice were not significantly different from those in the non-treated mice. However, in the treated mice, the IJk expression of Lyt2+ cells intensified. These results indicate that, following a single painting of DNFB onto Langerhans cell-deficient skin, the numbers of Lyt2+ cells do not change significantly, but do change functionally.
