Figure 4From: EGFR-specific T cell frequencies correlate with EGFR expression in head and neck squamous cell carcinomaCorrelations between the EGFR score and frequency of EGFR-specific CD8+ T cells in PBMC. The frequency of EGFR-specific T cells in PBMC of HNSCC patients is given in percent (%) of CD8+ T cells for YLN-tetramer (a) and KLF-pentamer (b). The EGFR score reflected the staining intensity and frequency of EGFR positive cells in corresponding tumor samples.Back to article page
