what is t-cell repertoire

Antigen-specific T cell clones are extremely rare, so scanning for the antigen specificity of polyclonal T cells must be highly efficient to combat invading pathogens in a timely manner. Early, high-resolution metrics are needed to ascertain the immune response to vaccinations.

This is achieved by the genomic recombination process that selects variable (V), joining (J), and, in some cases, diversity (D) gene segments from the multiple genomic copies. T cells play an essential role in the body’s fighting against the virus invasion, and the T cell receptor (TCR) is crucial in T cell-mediated virus recognition and clearance.
