Fig 1. pNK and YT cells have a contact-dependent antimicrobial effect on P. aeruginosa PAO1.

P. aeruginosa PAO1 cultured alone or in the presence of YT cells (A) or pNK cells (B). (C) CFU of P. aeruginosa PAO1 incubated alone, separated by a 0.1um filter, or in direct contact with YT cells for 6 h. In all co-culture experiments, conditions were carried out in n = 4 wells (mean ± SEM) and the graph is representative of n ≥ 3 biological replicates performed on different days. ** = P≤0.01, *** = P≤0.001. NS not significant.
