摘要:: Unlike any other cell type, T cells have a unique potential to eliminate cancer cells and to eventually cure cancer patients. As a result, researchers have made extensive efforts over the past three decades to develop therapeutics with the potential to mount T cell responses against cancer cells. One way in which such T cell responses can be triggered is by vaccines and adjuvants, potentially leading to tumor-specific T cell clones and lasting immunity. Alternatively, they can be induced with the help of recombinant proteins that either are expressed in patients’ T cells by gene therapeutic means, or are delivered to patients as pharmaceuticals for temporary engagement of T cells. With both recombinant technologies, cytotoxic T cells can be engaged for cancer cell lysis regardless of T cell receptor specificity and with the prospect of bypassing both complex T cell regulation and frequent immune escape mechanisms of tumor cells. In this review, we will focus on recombinant approaches for T cell engagement that currently are in clinical development. Approaches transfecting patient T cells with genes encoding recombinant T cell receptors or antibody fusion proteins will be compared to those temporarily engaging T cells by infused recombinant bispecific proteins. Initial experience has recently been gained in the clinic with both technologies such that their fundamental differences can now be discussed on the basis of patient data.
