Article Title: M1 macrophage-derived exosomes and their key molecule lncRNA HOTTIP suppress head and neck squamous cell carcinoma progression by upregulating the TLR5/NF-κB pathway

doi: 10.1038/s41419-022-04640-z

Figure Lengend Snippet: A The infiltration levels of immune cells in HNSCC. B Prediction of overall survival according to high- and low-infiltration levels of M0, M1 and M2 macrophages. THP-1-derived M0, M1 and M2 macrophages were confirmed by flow cytometry using ( C ) CD14 plus CD86 and ( D ) CD14 plus CD163 ( n = 3). E The exosomes were extracted from three types of macrophages and confirmed by electronic microscopy and Western blot analysis using CD9 and CD63. F RT-qPCR was conducted to test the expression of HOTTIP in M0, M1 and M2 macrophages ( n = 3). RT-qPCR was conducted to test the expression of HOTTIP in wild type M1 macrophages, HOTTIP-overexpressed and HOTTIP-knockdown M1 macrophages ( G ) and their exosomes ( H ) ( n = 3). Data are presented as mean ± SD. Results were analyzed by One-way ANOVA with a post hoc t -test. Significance: * P < 0.05, ** P < 0.01, *** P < 0.001.

Article Snippet: The cells were dissociated at 4 °C with PBS-EDTA, resuspended in calcium- and magnesium-free PBS and incubated at 4 °C with an anti-CD14 primary antibody (human: 11-0149-42, eBioscience, USA; mice: 123307, Biolegend, American) for 1 h. After the cells were washed with PBS, they were incubated with a fluorescein-conjugated anti-mouse IgG secondary antibody at 4 °C for 45 min. Then, the cells were suspended in a PBS solution.

Figure Lengend Snippet: A–D Flow cytometry assay detected CD14 + CD86 + M1 and CD14 + CD163 + M2 phenotype in circulating blood of nude mice bearing with HOTTIP-knockdown Hep-2 cells ( n = 3). HOTTIP-knockdown Hep-2 cells suppressed the polarization of M1 monocytes ( A , C ) but induced the polarization of M2 ( B , D ). E – H Flow cytometry assay detected M1 and M2 phenotypes in the blood of tumor-bearing nude mice treated by M1 exosomes ( n = 3). M1 exosomes induced the polarization of M1 monocytes ( E , G ) but inhibited the polarization of M2 ( F , H ). Data are presented as mean ± SD. Results were analyzed by One-way ANOVA with a post hoc test. Significance: ns not significant, ** P < 0.01, *** P < 0.001.
