Expression of transcription factor AP-1 and NF-kappaB in anergic T cells / 中国免疫学杂志

ABSTRACT

Objective:To explore the relationship between transcription factor AP 1 and NF kappaB and IL 2 decrease in anergic T cells.Methods:Nuclear proteins of activated T cells and anergic T cells were extracted and then the expression of AP 1 and NF kappaB were determinated by gel electrophorotic mobility shift assay.Results:Compared to activated T cells,anergic T cells expressed defective AP 1 transcription factor;there were three forms NF kappaB complex in both activated T cells and agergic T cells,but NF kappaB transcription activity was higher in anergic T cells than that in activated T cells.Conclusion:It has been demonstrated that these alteration of transcription factors have been likely to be responsible for repression of IL 2 in anergic T cells.
