(A) Time-dependent changes in cytokine and chemokine production in LPS-stimulated THP-1 cells. After LPS (10 μg/ml) treatment for 15, 30, 60, or 120 min without any agents and with minocycline (50 μg/ml), tigecycline (50 μg/ml), or doxycycline (50 μg/ml), cytokines and chemokines were measured using Multi Plex according to the manufacturer’s protocols. * p<0.05 compared with LPS only at 60 min. ** p<0.05 compared with LPS only at 120 min. Mino: minocycline, Tige: tigecycline, Doxy: doxycycline. (B) The rate of cytokine and chemokine production in the THP-1 cell line compared to the production of cytokines and chemokines by LPS stimulation without tetracyclines. After LPS treatment (10 μg/ml) for 30, 60, 120 or 240 min without any agents and with minocycline (50 μg/ml), tigecycline (50 μg/ml), or doxycycline (50 mg/ml), cytokines and chemokines were measured with Multi Plex.
