Abstract

Epigallocatechin-3-<i>O</i>-gallate (EGCG) is the major component of green tea extract, commonly found in dietary supplements, and has been associated with immune-mediated liver injury. The purpose of this study was to investigate the immunogenicity of EGCG in healthy donors expressing HLA-B*35:01, and characterize EGCG responsive T-cell clones. We have shown that EGCG can prime peripheral blood mononuclear cells and T-cells from donors with and without the HLA-B*35:01 allele. T-cell clones were CD4<sup>+ve</sup> and capable of secreting Th1, Th2, and cytolytic molecules. These data demonstrate that EGCG can activate T-cells <i>in vitro</i>, suggesting a significant role in the pathogenesis of green tea extract induced liver injury.
