Figure Lengend Snippet: Viability of tumor cells co-cultured with activated Jurkat cells and incubated with different antibodies. ( A ) Viability of tumor cells co-cultured with Jurkat cells incubated with the indicated antibodies for 48 h. In the "A549 and Transwell" and "MGC-803 and Transwell" group, Jurkat cells were added to the upper compartment of the Transwell inserts and A549/MGC-803 were seeded in the lower compartment to avoid direct contact between cell types. The results are expressed as the mean ± SD from triplicates. * P < 0.05, ** P < 0.01. ( B ) Image of A549 cells and MGC-803 cells co-cultured with Jurkat cells after incubation with the indicated antibodies for 48 h by optical microscopy.

Article Snippet: Human non-small cell lung cancer cell lines A549 and PC-9, human esophagogastric adenocarcinoma cell lines HGC-27 and MGC-803, and the human T-lymphoblastic leukemia Jurkat cell line were obtained from the American Type Culture Collection (ATCC) (Manassas, VA, USA).

Figure Lengend Snippet: LBL-007 and anti-PD-1 antibodies promote IL-2, IL-10, and TNF production. ( A ) ELISA of IL-2, IL-10, and TNF in the supernatants of the co-culture model after incubation with the indicated antibodies for 48 h. “A549” refers to the Jurkat-A549 co-culture model, "MGC-803" refers to the Jurkat-MGC-803 co-culture model. ( B ) qPCR of IL-2, IL-10, and TNF in cells from the Jurkat-A549 co-culture model (upper layer) or the Jurkat-MGC-803 co-culture model (lower layer) after incubation with the indicated antibodies for 48 h. The results are expressed as the relative expression of the gene normalized to the endogenous control and to the sample with the lowest expression set as 1 in each type of cell. The results are expressed as the mean ± SD from triplicates. * P < 0.05, ** P < 0.01, *** P < 0.001.
