    摘要: An object is to provide a TCR cloning system that enables not only bias-free analysis of TCR repertoires, but also collection of antigen-specific TCR α/β cDNA pairs and evaluation of functions thereof. There is provided a method for producing a gene of T cell receptor (TCR) specific to an antigen A, which comprises 1) the step of stimulating a group of T cells including a T cell specific to an antigen A or one T cell specific to an antigen A under a condition effective for amplification of a TCR gene; 2) the step of identifying a T cell specific to an antigen A among the group of T cells including a T cell specific to the antigen A, and sorting one T cell specific to the antigen A into a vessel; and 3) the step of subjecting the one activated T cell specific to the antigen A in the vessel to PCR to amplify a gene of TCR specific to the antigen A. According to the present invention, a target TCR gene can be cloned within a shorter time compared with that required by the conventional methods, for example, about ten days. Further, according to the present invention, genes of TCR α chain and β chain can be highly efficiently cloned. Under the conditions of the examples, a pair of a TCR α chain and TCR β chain could be obtained from stimulated T cells sorted as single cells at a ratio of 100%.

    摘要: An object of the present invention is to stimulate a T cell without using a peptide/MHC tetramer. In the present invention, the step of supplying an antigen peptide to a T cell having a T cell receptor (TCR) that can recognize the antigen peptide on cell surface to form a complex of a major histocompatibility complex (MHC) molecule on the cell surface of the T cell and the antigen peptide is used, and the T cell is stimulated through recognition by TCR of the antigen peptide as the MHC molecule-antigen peptide complex on the cell surface of the same T cell. Such a stimulating and activating method would be applicable to not only T cells, but also various cells. According to the present invention, an antigen-specific T cell can be identified without establishing any antigen-specific T cell strain, and without using such a reagent as MHC/peptide tetramer. That is, a cancer-specific T cell can be efficiently and conveniently identified.
