The present invention relates to T cells, in particular a non-activated T cell, comprising an exogenous nucleic acid encoding a T cell Receptor (TCR) specific for a virus. An embodiment of the invention is directed to a non-activated (resting) T cell expressing Hepatitis B virus (HBV) envelope s183-191 TCR capable of inhibiting viral replication and which shows reduced expression of perforins and/or granzymes in response to stimulation as compared to an activated T cell expressing the said TCR. Also encompassed are methods for producing such cells, compositions, pharmaceutical compositions and kits comprising such cells and medical uses thereof.
