Transcription profiling of humoral resistance to the CTL after phenotypical and functional study of the resistant clone IGR-HeuR8

From a tumoral line IGR-Heu; resulting from a biopsy of the primitive tumour of a patient reached of a bronchial cancer not with small cells (NSCLC); we established; by successive co-cultures of this line with the autologous CTL (clone T H161); a resistant line to the cytotoxic lysis induced by H161 (IGR-HeuR8 line). This resistant line was then cloned by limiting dilutions and a resistant clone was obtained (tumoral clone IGR-HeuR8). The goal of this study is to define profiles of genetic expression of the tumoral resistance to the CTL after phenotypical and functional study of the resistant clone IGR-HeuR8.
