Modification of 2 amino acids in the CDR3α or CDR3β sequence further increased the similarity to 100% with published CDR3α and CDR3β sequences, that also included peptide cancer antigens hemoglobin-like protein (HbO), EphA2, NY-ESO-1, MART1, and T72 (Tn), hepatitis, COVID, cytomegalovirus, and Epstein-Barr, influenza and Yellow fever viral antigens (Table S3).41–45. This evidence concerns the gene EPHA2 and hepatitis A virus infection.
