P53 mutation tcr
WebBackground EGFR, KRAS and TP53 have frequent somatic hotspot mutations giving rise to biologically relevant amino acid substitutions in EGFR, KRAS and p53 proteins, respectively, that can be processed and presented on the cell surface by human leukocyte antigen (HLA) molecules as neoantigens to T cells through their T-cell receptor (TCR). These mutations … Webto re-direct the specificity of T cells towards p53 and KRAS neoantigens and to characterize the resultant engineered TCR-T cell populations for specificity and function. Genes encoding the alpha and beta chains of p53 or KRAS neoantigen-specific TCRs were linked by a 2A ribosomal slip site linker and cloned into the clinical. Sleeping Beauty ...
