From: Glycosaminoglycans are involved in bacterial adherence to lung cells
Effect of peptides with heparin binding sequences on pathogen attachment to lung cells. The effects of QKKFKN and FKKKYGKS (20 nM final concentration) on bacterial binding to A549 cells (a) and to MRC5 cells (b). c Relative differences in mean bacterial adherence inhibition between lung cells in competition with each individual peptide. Data are shown normalized to the control represented by binding in the absence of interfering molecules. The spreads represent standard deviation. Statistically significant differences are denoted by * for p < 0.05
