![]() Using a previously published repertoire sequencing dataset paired with high-resolution genome-wide genotyping from a large human cohort, we infer specific genetic loci associated with V(D)J recombination probabilities using genome-wide association inference. The extent to which an individual’s genetic background is associated with their resulting TCR repertoire diversity has yet to be fully explored. T cells combine a random V(D)J recombination process with a selection process to generate highly diverse and functional TCRs.

In conclusion, intensive studies over an extended range of cancer types and a broadened group of subjects should be carried to solidify the TCR repertoire's position as an immunotherapy biomarker. Recent progress of TCR sequencing technology in tumor research is also discussed. In this article, we reviewed TCR rearrangement mechanisms and analysis methods. The results of some studies are even contrary. Still, existing researches are insufficient to clarify the specific clinical implications of TCR dynamic change and the definite role of TCR repertoire diversity during the treatment process. Accurate delineation of the T-cell repertoire can further the understanding of the immune system response to tumorigenesis. The potential of TCR repertoire as a biomarker for immunotherapy efficacy is also widely studied as TCR repertoire represents different baseline within individuals and shows dynamic change during treatment. Results have shed light on the TCR repertoire differences between cancer patients and healthy control as well as between individual's lesions, paracancer, and peripheral blood samples. Based on this new methodology, discoveries are made across a range of tumor types. Nowadays, next-generation sequencing technology allows the simultaneous detection of TCR sequences with high throughput, and several evaluation indexes facilitate the measure of TCR repertoire. Thus, TCR repertoire analysis occupied an important position in T-cell regarding research. The unique rearrangement mechanisms during T-cell maturation provide great diversity to TCR, ensuring specific recognition between T cells and antigens. Mature T cells can specifically recognize the antigen on the major histocompatibility complex (MHC) molecule through T-cell receptors (TCR). T cells, which are involved in adaptive immunity, are essential in the elimination of tumor cells.
