The effect of LPS on bovine neutrophil apoptosis at 24 h in the presence of RGDSK⁵/K⁹⁵–RNT. The percentage of neutrophil apoptosis is displayed as mean ± SEM of 5 separate experiments (A). The level of apoptosis was measured by Annexin V-FITC staining after 24 h incubation without LPS-pretreatment (B) and with LPS-pretreatment (C). Significant differences between treatment groups are expressed by different letters above bars.
