Webb28 juni 2016 · The TCRB clonotype ranking 3 rd in frequency in the CD8 + PD-1 + TIL was associated with two productive TCRA chains but none of the two combinations (3998-3A1 and 3998-3A2) were tumor reactive. For tumor sample 3998, 345 non-synonymous mutations were identified ( Table 1 ). WebbIn TCRa훽, various CDR regions of both the TCRa and TCR훽 chains are involved in pMHC recognition, depending on the particular TCR and pMHC involved In some cases, the CDR1, CDR2 and HV4 regions interact with residues on the MHC class 1 or Class 2 protein itself, while class 2 protein itself, while the highly diverse CDR3 regions preferentially make …
