Abstract：
:Pathogens such as the human immunodeficiency virus (HIV), the hepatitis B and C virus (HBV, HCV) and certain strains of the rodent lymphocytic choriomeningitis virus (LCMV) establish a state of persisting viral replication. This occurs besides strong adoptive immune responses and the induction of large numbers of activated pathogen-specific T-cells. The failure of the immune system to clear these viruses is typically attributed to a loss of effector T-cell function-a phenomenon referred to as T-cell exhaustion. Though largely accepted, this loss of function concept is being more and more challenged by comprehensive clinical and experimental observations which highlight that T-cells in chronic infections are more functional than previously considered. Here, we highlight examples that demonstrate that such T-cells mediate a profound form of immune-surveillance. We also briefly discuss the opportunities and limitations of employing 'exhausted' T-cells for therapeutic purposes.
