Abstract:
Cytotoxic T cells can specifically kill target cells that express antigens recognized by the T-cell receptor. These are membrane-bound proteins that are not ubiquitous and thus are difficult to purify and study at the protein level. The advent of recombinant DNA technology has facilitated these objectives, thereby enabling researchers to gain valuable information about major T-cell receptor characteristics. Genetic manipulation of T-cell receptors has also been used to exploit specificity of killing by cytotoxic T lymphocytes, which represents an attractive feature for therapeutic purposes. The objective of this review was to provide an overview of the major strategies adopted to genetically manipulate T-cell receptors.
