Active Release of Immunogenic Molecules and Chemokines by OBP-502 In Vitro
(A) Extracellular ATP secreted from CT26 and PAN02 cells was measured using a luminescence assay 24 h after OBP-502 treatment (0, 500, and 1,000 MOI). *p < 0.001. (B) Extracellular HMGB1 secreted from CT26 and PAN02 cells was measured using an ELISA 24 h after OBP-502 treatment (0, 500, and 1,000 MOI). *p < 0.001, **p < 0.005. (C) Cytokines and chemokines secreted from CT26 cells were measured using multi-cytokine and chemokine assays 24 h after OBP-502 treatment (0 and 1,000 MOI), and ratio of 1,000 MOI to 0 MOI was plotted for each cytokine or chemokine. (D) CCL5/RANTES secreted from CT26 cells and PAN02 cells was measured using an ELISA 24 h after OBP-502 treatment (0, 500, and 1,000 MOI). *p < 0.001.
