CD8A and skin basal cell carcinoma: Comparison of the per-patient MHC-I scores between BCC and PDAC for each of the CD8+ T cell subclusters shows that regardless of the subcluster, BCC CD8+ T cells have significantly elevated MHC-I expression in comparison to PDAC; this discrepancy is most pronounced in memory CD8+ T cells, where MHC-I scores are on average 4 times higher (Figure 2F).
