Figure Lengend Snippet: Cytotoxic activity and inflammatory cytokine release in co-culture systems. a–c After co-culturing WT or KO, T cells, and TDB, the color reaction with WST-8 reagent in an hour was measured. The co-culture times were 24 h, 48 h, and 72 h of co-culture, respectively. Red: WT + T cell + TDB, blue: KO + T cell + TDB. Error bars represent the mean ± SD ( n = 6), ** p < 0.005, *** p < 0.0005, n.s. not significant. d Measurement of IFN-γ release by ELISA after 24 h of co-culture time. Co-culture supernatants were obtained and used for assay using the ELISA Kit. Red: WT + T cell + TDB, blue: KO + T cell + TDB, gray: negative control (T cell + TDB). Red letters are the results of the WT and N/C statistical tests, and blue letters are the results of the KO and N/C statistical tests. Error bars represent the mean ± SD ( n = 3), *** p < 0.0005, n.s. not significant. e IFN-γ release at TDB: 10 ng/mL for each co-culture time. Error bars represent the mean ± SD ( n ≧ 3), *** p < 0.0005, n.s. not significant. f Cancer cell death when the IFN-γ release measured in e is added to the standard. From left to right, IFN-γ release at 6 h, 24 h, 48 h, and 72 h was added. Error bars represent the mean ± SD ( n ≧ 3), *** p < 0.0005, n.s. not significant. g-i TNF-α version of the same experiment as d – f

Article Snippet: T cells (E:T = 5:1, 1.0 × 10 6 cells/50 μL/well) were added and co-cultured. hEx3 was added at a final concentration of 0.1–100 ng/mL in 100 μL of medium and cultured for 24 h. The culture supernatant was then collected and assayed using human IFN-gamma ELISA Kit, human TNF-alpha ELISA Kit, human CXCL10 ELISA Kit (Proteintech, Rosemont, IL), and human HMGB1 ELISA Kit (Chondrex, Woodinville, WA) according to the protocols provided.

doi: 10.1016/j.intimp.2021.107797

Figure Lengend Snippet: N-IgY inhibited IFN-γ secretion stimulated by NP in PBMCs. Group N: PBMCs were treated with NP (20 μg/mL) alone for 18 h. Group N + IgY: NP was premixed with N-IgY (1 mg/mL) for 30 min and then incubated with PBMCs for 18 h. Group Con: PBMCs were treated with PBS as control for 18 h. IFN-γ in the culture supernatant was measured by ELISA.

Article Snippet: Human IFN-γ ELISA kit (MULTI SCIENCES, China) was used to detect the secretion of IFN-γ in the culture supernatant according to the operating manual.
