d, Bacteriacolony-forming units (c.f.u.) in primary BMDMs infected with L. monocytogenes ΔactA mutant strain DPL-4029 for 30 min and treated with peptide (10 µM from 0 to 2 h post-infection). Bars represent mean ± s.e.m. of triplicate samples. Similar results were observed in three independent experiments.
