The results show specific recognition of peptide epitope Rv1733cp181189 byCD8+Tcellswhen peptide was loaded onto EBVBLCL JY target cells (compared to medium control). CD8+ T cells also recognizedEBVBLCLJYtargetcells that had been transduced with an expression plasmid encoding Rv1733c, thus facilitating endogenous expression and presentation of Rv1733c in the b context of HLAA*0201. In contrast EBVBLCL JY target cells which were transduced with an empty plasmid (a) were killed to a much lesser extent. Specific lysis of EBV BLCL JY target cells loaded with Rv1733cp181189 could be inhibited partly by addition of antiHLA classI but not antiHLAclassII antibody (b). The % specific lysis wascalculatedasfollows:[(release spontaneous release)/ (maximum releasespontaneous release)] x 100%. . ͵.
