Characteristics of clone 2C4. The procedure used for clone 2C4 was the same as the one described in Figs. 2 and 3. a Recognition of EBV-B cells loaded with recombinant gB-expressing bacteria by CD4⁺ T-cell clone 2C4. b Recognition of gB overlapping peptides by CD4⁺ T-cell clone 2C4. c Identification of the minimal gB epitope recognized by by CD4⁺ T-cell clone 2C4. d Inhibition of the gB peptide recognition by anti-HLA-DP, -DQ or -DR Abs
