Figure Lengend Snippet: Increased NLRP3 expression in TAMs predicts poor prognosis in HNSCC. a The ratio of M1 (CD64, CD68) and M2-like macrophage (MRC1, CD163) signatures in the low-expression (n = 259) and high-expression NLRP3 groups (n = 259) in the TCGA HNSCC database (***, P < 0.001). b Co-immunofluorescence staining of NLRP3 (red) and CD206 (green) in human HNSCC tissue. The white arrow shows co-expressed cell (yellow). T, tumor area; S, stromal area. Bar, 50 μm. c Flow cytometry to detect NLRP3 expression (mean ± SD) in CD206+ TAMs in human HNSCC PBMCs (n = 6) and TILs (n = 5). d Quantitative statistical analysis of NLRP3- and CD206-positive populations on gated cells (**, P < 0.01; ***, P < 0.001). e Correlation analysis of CD14+/CD206+/NLRP3+ and CD14+/CD206+ cell proportions in HNSCC patient PBMC and TIL, n = 11. f Representative IHC staining of NLRP3, CD206 and CD163 in human HNSCC using serial sections. Bar, 50 μm. g Correlation analysis between NLRP3, CD206 and CD163 protein expression in HNSCC tissue microarray using histoscore, n = 157. h Correlation analysis between NLRP3, MRC1 (CD206 encoding gene) and CD163 RNA expression in the TCGA HNSCC database. unit, expression (RSEM, Log2(Val + 1)), n = 520. i Hierarchical clustering plot of NLRP3, CD11b, CD206 and CD163 in HNSCC based on histoscore. n = 74. j Survival curves of high NLRP3 and CD206 expression vs. low NLRP3 and CD206 expression patients; high NLRP3 and CD163 expression vs. low NLRP3 and CD163 expression patients; low NLRP3 on high CD206 expression vs. high NLRP3 on CD206 high expression patients; and low NLRP3 on high CD163 expression vs. high NLRP3 on CD163 high expression patients.
