The interaction between cecropin-TY1 and LPS. a Enhancement of the intensity of FITC-labeled LPS at different concentrations of cecropin-TY1 as indicated. Data were presented as mean ± SEM. *P <0.05, **P < 0.01, values of peptide-treated groups are significantly different from that of PBS-treated group. b Cecropin-TY1 neutralized LPS at different concentrations as indicated. LPS-neutralizing activity of cecropin-TY1 was determined by TAL assay kit. Data were presented as mean ± SEM. *P <0.05, **P < 0.01, values of peptide-treated groups are significantly different from that of PBS-treated group. c LPS-neutralization activity of cecropin-TY1 and its derivatives (5 μM). Data were presented as mean ± SEM. *P <0.05, **P < 0.01, values of derivative-treated groups are significantly different from that of cecropin-TY1-treated group
