Table S1, shows that the phenotype of iDC generated from monocytes obtained from HD and HNSCC are not different. However, as shown in Figure S1A and S1B, intracytoplasmic staining of iDC for various APM components revealed a significantly lower expression (p<0.01) of TAP1 and TAP2 in iDC of HNSCC patients relative to that in iDC of HD. This evidence concerns the gene TAP2 and head and neck squamous cell carcinoma.
