Figure Legend Snippet: Gene expression and GSEA analysis of IL6 in TCGA HNSCC cohorts. A Differential analysis of IL6 expression between HPV − and HPV + HNSCC cohorts using TCGA dataset. B DEGs stratified by IL6 high and low expression in HPV − HNSCC cohort. C Expression correlation analysis between IL6 and the top nine upregulated DEGs identified in the IL6 high-expression group. D Pathway enrichment analysis (IL6 high expression vs IL6 low expression) revealing the ‘natural killer cell mediated cytotoxicity’ pathway in TCGA HPV − HNSCC cohort. E Correlation between the expression of IL6 and the other 4 DEGs upregulated in HPV − HNSCC cells vs HPV + HNSCC cells. F Correlation analysis of the gene expression between IL6 and CCR2 in TCGA HPV − HNSCC cohorts

Figure Legend Snippet: Blocking IL6 signaling induces the remission of HPV − tumors in orthotopic tumor mouse models. A IL6 concentration in the peripheral serum of C57BL/6 mice bearing MOC2 or TC-1 tumors. B Schematic showing the timeline of experimental procedures. Male C57BL/6 mice at 6–8 weeks of age received intramucosal injection of 1.0 × 10 6 MOC2 or TC-1 cells. When tumors were established (10 days after cell inoculation), mice were randomized to receive the treatment of IgG2 isotype or αIL6 (100 µg/mouse) ( n = 5/group). C , D MOC2 tumor growth curve and weight in each treatment group. E , F TC-1 tumor growth curve and weight in each treatment group. In ( C ) and ( E ), representative tumors from C57BL/6 mice with indicated treatment are shown in the upper panel. * p < 0.05; ns: not significant
Techniques Used: Blocking Assay, Concentration Assay, Injection

Figure Legend Snippet: αIL6 and RS504393 promote NK cell antitumor activity and repress MOC2 tumors more effectively when combined. A , F Schematic showing the timeline of experimental procedures. Male C57BL/6 mice at 6–8 weeks of age received intramucosal injection of 1.0 × 10 6 MOC2 or TC-1 cells. When tumors were established (10 days after cell inoculation), mice were randomized to receive the treatment of IgG2 isotype, αIL6 (100 µg/mouse), RS504393 (6 mg/kg) or the combination of αIL6 and RS504393 ( n = 5/group).

Figure Legend Snippet: Depletion of NK cells attenuates the antitumor activity of the αIL6 and RS504393 combination in orthotopic mouse models. A Schematic showing the timeline of experimental procedures. Male C57BL/6 mice at 6–8 weeks of age received intramucosal injection of either 1.0 × 10 6 MOC2 or MOC1 cells. Tumor-bearing mice were randomized to receive the combination treatment of the αIL6 (100 µg/mouse) and RS504393 (6 mg/kg), in the presence of αASGM1 or rabbit polyclonal IgG isotype ( n = 10/group).

Figure Legend Snippet: A proposed model for this study. A In the microenvironment of HPV − HNSCC, IL6/IL6R and CCL2/CCR2 signaling exert a significant influence on the ability of HPV − tumor cells to evade immune attacks by NK cells. B Simultaneous blockade of IL6/IL6R and CCL2/CCR2 with αIL6 and RS504393 is effective in enhancing the antitumor activity of NK cells in HPV − HNSCC
