Fig. 3

Topoisomerase-I-specific CD4+ T cells activation is HLA-DR restricted. PBMC from topo-I-positive SSc patients were cultured for 18 h with topo-I and anti-HLA-DR or anti-HLA-DP blocking antibodies or isotype control (1 ug/ml). Values are represented as percent of response relative to the frequency of CD154 + CD69 + CD4+ cells detected after stimulation with topo-I alone as assessed by flow cytometry. Data are representative of three separate experiments (mean ± SD)
