THP-1 infection assay. PMA-stimulated THP-1 cells were infected at a MOI of 1. (a) P. aeruginosa (ATCC27853). (b) S. aureus (ATCC43300). Incubation of the bacteria without cells served as control. After 1 h incubation, the samples were either irradiated with 405 nm light with a dose of 25 J cm−2 or kept in the dark. Values represent survival of the irradiated samples in comparison to the dark control. The mean and standard deviation of three independent biological replicates with each three technical replicates are illustrated. Statistically significant differences between the irradiated samples and their respective controls are indicated with an asterisk (*p < 0.05).
