Cancer is the second most common cause of death in the world, and the number of people with the disease increases each year. The therapy of the disease currently stands on four pillars; surgery, chemotherapy, radiotherapy, and immunotherapy. Through the past few years, immunotherapy has become the fastest developing treatment modality. However, despite its unprecedented efficacy in some patients, the majority of patients still does not respond to the therapy. Therefore, there is a need to investigate the mechanisms that make immunotherapy inefficient. Cell-based cancer immunotherapy is the treatment modality which uses live ex vivo-produced tumor-targeting immune cells to treat cancer. One of the mechanisms that may compromise its therapeutic efficacy is the expression of inhibitory molecules on the surface of the produced immune cells. Tim-3 is the inhibitory molecule which attracts attention in recent years. Tim-3 expression in the tumor cells and the tumor-infiltrating immune cells is often associated with worse prognosis and more aggressive forms of the disease. However, its role in the in vitro or ex vivo-produced immune cells is difficult to predict. In this work, an in vitro study model which is based on in vitro-produced antigen-specific CD8+ T cells with high expression of Tim-3 has been...
