Abstract
The HLA class I allele HLA-A*33:03 is a risk factor for ticlopidine-induced liver injury. Herein, we show HLA class I-restricted ticlopidine-specific CD8+ T-cell activation in healthy donors expressing HLA-A*33:03. Cloned CD8+ T-cells proliferated and secreted IFN-γ in the presence of ticlopidine and autologous antigen presenting cells. A reduction of the T-cell response after blocking with HLA-class I and HLA-A*33 antibodies indicates that the interaction between drugs and the HLA allele detected in genetic association studies may be important for T-cell activation.

Abstract
In 1997 a novel virus in the serum of a patient with acute post-transfusion hepatitis of non A-G etiology was identified. This agent was designed TT virus (TTV). It produces persistent viremia and no disease, but the mechanism of its persistence is poorly understood. In the present study mRNA expression of antiviral proteins as MxA, 2' 5' OAS, anti-apopotic protein, cytokines IL- 28, IL- 29 and IFN are examined in a subject affected by B lymphoma and positive for TTV DNA and RNA in this cellular subset, and in BJAB and Dohh2 cell lines.
