Figure 6From: Detailed characterization of tumor infiltrating lymphocytes in two distinct human solid malignancies show phenotypic similarities Expression of IL-6 by qPCR in PBL and TIL. CD4+ T cells were enriched from paired blood and tumor specimens and qPCR was performed on the enriched cell populations as described in Methods. The fold difference in IL-6 message in the TIL was normalized to the paired PBL in CRC samples (A) and OC samples (B).Back to article page
