Effects of CA on the content of inflammatory-related factors in yak PBMCs. Cells were induced by 1μg/mL LPS, 60μg/mL CA, and 60μg/mL CA + 1μg/mL LPS for 48h. IL-6, IL-8, IL-1β, IFN-γ, TNF-α and IL-10 secretion of PBMCs in yak was detected by ELISA. * – P < 0.05; ** – P < 0.01. P values are compared with the control group. # – P < 0.05; ## –P < 0.01.
