Figure Lengend Snippet: TLR4 is involved in the capture of shed EBOV GP. ( A ) Binding and internalization assays on 293 cells stably expressing TLR4 (293-TLR4) and THP-1 cells were analyzed by western blotting. Cells were treated or mock-treated with recombinant TLR4 (rTLR4) and then cultured with medium or WT, mut 5, and mut 14 EBOV shed GP. Cells were then treated with trypsin to evaluate internalization of shed GP. Cell pellets were immunostained for TLR4, EBOV GP, and GAPDH as an internal control. ( B, C ) Induction of NFκB and NFAT. 293-TLR4 cells were transfected with NFAT-Luc ( B ) or NFκB-Luc ( C ), treated with CLI-095 or rTLR4 with or without CsA, treated or mock-treated with WT, mut 5, or mut 14 EBOV shed GP, and subjected to luciferase assays. Two-way ANOVA followed by a Tukey’s multiple comparison test: * P < 0.05; ** P < 0.01; *** P < 0.001; **** P < 0.0001; ns, not significant.

Article Snippet: 293T and 293-TLR4 cells were seeded at 10 5 cells per well in 12-well plates (Sigma-Aldrich), transfected with NFκB-Luc (Addgene, #111216) or NFAT-Luc (Addgene, #17870) plasmids using TransIT LT1 transfection reagent (Mirus Bio LLC) and incubated at 37°C for 48 h. Cells were then stimulated with 25 ng/mL TPA and 0.5 μM of ionomycin, or 1 μM of CsA, 10 μg/mL of rTLR4 (RnD Systems, #1478-TR-050), or 100 ng/mL CLI-095 (InvivoGen) for 1 h. Next, cells were pulsed with medium alone or with EBOV VLPs for an additional 24 h. Then, cells were lysed with Pierce Luciferase Cell lysis buffer (Thermo Fisher Scientific), and cell lysates were assayed for luciferase activity using a luminometer (Glomax 20/20, Promega).
