The high-scored peptide regions over mouse-related MHC-I prevalent alleles (MHC-2Db, MHC-2Dd, MHC-2Kd) were selected from IEDB and NHLAPred online servers for each of three NSCLC-related antigens (sp17, AKAP4, and PTTG1) (Tables 1, 2, and 3). The gene discussed is PTTG1; the disease is non-small cell lung carcinoma.
