Given the multipronged effects of tapasin-TM observed in the immunopeptidomes of the six neuroblastoma cell lines (Fig. 8, B and C), we chose to analyze the full set of 38,310 pooled peptides identified in both parental and tapasin-TM–expressing cells (Fig. 8, A, D to F). The gene discussed is TAPBP; the disease is neuroblastoma.
