Fig. 5From: Immunomodulatory effects of Rhipicephalus haemaphysaloides serpin RHS2 on host immune responsesCytotoxicity assay. OVA-CD8-activated CD8+ cytotoxic lymphocytes were used as effector cells, whereas the OVA-expressing B16F10 cells were used as target cells. Triton X-100 was added to the positive control group. The data are presented as the percent specific lysis of the target cells in a 2 h RHS2-stimulate assay. Each point represents the mean of triplicate cultures. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001Back to article page
