Isolation and molecular characterization of T cell subsets from <t>PNH</t> patients ( A ) Gating strategy for T cell subsets for cell sorting. <t>PBMCs</t> were stained with ViViD, anti-CD14-Pacific Blue, anti-CD19-Pacific Blue, anti-CD3-BV605, anti-CD4-V500, anti-CD8-APC-H7, anti-CD45RA-PE-Cy7, and anti-CD45RO-APC. Lymphocytes were gated based on their scatter characteristics or forward scatter height vs. forward scatter area. Live T cells were gated based on positive for CD3 and negative for ViViD, CD14, and CD19 to remove dead cells, monocytes, and B cells. CD4 + and CD8 + T cells were then gated based on the characteristic expression patterns of CD45RA and CD45RO. Four different T cell subsets [CD4 + naïve (CD45RA + CD45RO - ), CD4 + memory (CD45RA - CD45RO + ), CD8 + naïve (CD45RA + CD45RO - ), and CD8 + memory (CD45RA - CD45RO + ) T cells] were sorted for RNA-seq.

Exosomes from tumor patients with increased membrane-associated HSP72 and HSP105 induced DCs to promote tumor cell invasion via IL-6 in vitro . (A) After adsorption onto latex beads, HSP72 and HSP105 on EXO-PT and EXO-TT were detected by flow cytometry. RFI was calculated by dividing mean fluorescence intensity of samples staining with detection Abs by that of sample staining with ISO Abs (n = 7). (B) Human DCs were induced from PBMCs and stimulated with 5 μg/ml of EXO-PT or EXO-TT from breast tumor tissues for 6 h. The IL-6 production was measured by ELISA (n = 3). (C) MDA-MB-435S cells were cultured in supernatant from PBS-, EXO-PT- or EXO-TT (5 μg/ml for 6 h)-stimulated DCs with or without 30 μg/ml of anti-IL-6 or ISO mAbs for 24 h. Then, their invasive ability was measured using an in vitro invasive assay, and the cells on the bottom of the Transwell filter were imaged and quantified (Magnification: 200 ×). (D) The results of (C) were statistically analyzed (n = 5). (E, F) After adsorption onto latex beads, HSP72 and HSP105 on exosomes from sera of breast tumor patients or healthy controls were detected by flow cytometry. One representative result of 12 is shown (E). RFI was calculated and statistically analyzed (F). (B, D) The results are shown as the mean ± SEM of 3 independent experiments.

DCs with enhanced IL-6-secretion capacity were found in tumor-bearing mice and patients. (A, B) Mice were subcutaneously inoculated with 5 × 10 5 B16-F10 cells, and mice without tumor inoculation were used as controls. Then, DCs from splenocytes were isolated 1 week, 2 weeks or 3 weeks later and stimulated with PBS, 5 μg/ml B16-F10-EXO or 100 ng/ml of LPS for 6 h. IL-6 production by DCs was detected by ELISA (n = 3) (A). DCs from splenocytes were isolated 3 weeks later and cultured in vitro for 6 h. Culture supernatant was collected and B16-F10 cells were cultured in this supernatant for 24 h. Then, the invasive ability of B16-F10 cells was measured (n = 5). Control indicates B16-F10 cells without any treatment (B). SN-DC PBS or SN-DC tumor denotes supernatant from DCs of healthy control mice or tumor mice, respectively. (C) Mice were intravenously injected with 100 μl of PBS or 10 μg/100 μl of B16-F10-EXO. Then, DCs from splenocytes were isolated 12 or 24 h later and cultured in vitro for 6 h. IL-6 production by DCs was detected by ELISA (n = 3). (D) Human DCs were isolated from PBMCs from healthy volunteers (n = 27) or breast tumor patients (n = 18) and cultured in vitro for 6 h with or without 100 ng/ml LPS. IL-6 production by DCs was detected by ELISA. The results are shown as the mean ± SEM of 3 independent experiments or of all detected samples. P values were generated by a 2-tail student's t -test.

    DCs with enhanced IL-6-secretion capacity were found in tumor-bearing mice and patients. (A, B) Mice were subcutaneously inoculated with 5 × 10 5 B16-F10 cells, and mice without tumor inoculation were used as controls. Then, DCs from splenocytes were isolated 1 week, 2 weeks or 3 weeks later and stimulated with PBS, 5 μg/ml B16-F10-EXO or 100 ng/ml of LPS for 6 h. IL-6 production by DCs was detected by ELISA (n = 3) (A). DCs from splenocytes were isolated 3 weeks later and cultured in vitro for 6 h. Culture supernatant was collected and B16-F10 cells were cultured in this supernatant for 24 h. Then, the invasive ability of B16-F10 cells was measured (n = 5). Control indicates B16-F10 cells without any treatment (B). SN-DC PBS or SN-DC tumor denotes supernatant from DCs of healthy control mice or tumor mice, respectively. (C) Mice were intravenously injected with 100 μl of PBS or 10 μg/100 μl of B16-F10-EXO. Then, DCs from splenocytes were isolated 12 or 24 h later and cultured in vitro for 6 h. IL-6 production by DCs was detected by ELISA (n = 3). (D) Human DCs were isolated from PBMCs from healthy volunteers (n = 27) or breast tumor patients (n = 18) and cultured in vitro for 6 h with or without 100 ng/ml LPS. IL-6 production by DCs was detected by ELISA. The results are shown as the mean ± SEM of 3 independent experiments or of all detected samples. P values were generated by a 2-tail student's t -test.

    Cytotoxicity against a malignant pleural mesothelioma cell line mediated by cetuximab. (A) Cetuximab mediates cytotoxicity against the EGFR-expressing MSTO-211H mesothelioma cell line. Healthy human PBMCs, using 4 different E/T ratios, were tested for cytotoxicity in the presence or absence of cetuximab (2.5 μg/ml). The y-axis reveals cytotoxicity as determined by a 4-h 51 Cr release assays. (B) Concentration-dependent curve of cetuximab-dependent ADCC activity and NK activity against MSTO-211H cells by healthy human PBMCs. MSTO-211H cells were incubated with PBMCs at an E/T ratio of 20:1 along with or without indicated concentrations of cetuximab (0.0000025-1,000 μg/ml). Data are representative of 3 independent experiments. Points, mean of a triplicate experiment; bars, SD. (C) Correlation between EGFR expression levels of target malignant mesothelioma cell lines and cetuximab-mediated ADCC activity. The x-axis indicates the number of EGFR molecules expressed on the surface of the cancer cells. The y-axis represents the ADCC activity of cetuximab (0.25 mg/ml) as determined by a 4-h 51 Cr release assay. Healthy human PBMCs were incubated with or without IL-2 (30 IU/ml) at an E/T ratio of 40:1 for 18 h and tested for cetuximab-mediated ADCC activity against various 51 Cr-labeled cell lines. Data are representative of 5 independent experiments. The malignant mesothelioma cell lines used are indicated. Points, mean of a triplicate experiment; bars, SD.
