Epicutaneous lugdunin recruits phagocytic cells. a Schematic overview of the mouse experiments: 6–8-week-old female C5BL/6 wild-type (WT), MyD88-ko, or 5xTLR-ko mice were epicutaneously treated with 1.5 µg lugdunin or phosphate-buffered saline (PBS) as a control. After 24 h, mice were euthanized, immune cells were isolated from treated skin areas, and immune cell composition was analyzed by flow cytometry. b Shown is the mean percentage of CD45+ live cells in mouse skin of 10 C57BL/6 WT mice ± s.e.m. One mouse is represented as two dots analyzed by two different stainings. c Pie charts show the mean percentage of the different immune cell subsets in the skin of 10 WT mice after 24 h of PBS or lugdunin treatment. d Shown are representative flow cytometry data (left panel) and the mean percentage of neutrophils (Ly6C+Ly6G+) and monocytes (Ly6C+Ly6G−) pregated on CD11b+CD45+ live cells (see Supplementary Fig. 3a, f for the gating strategy) in mouse skin ± s.e.m. One dot represents one mouse. *P < 0.05. e Representative myeloperoxidase (MPO)-stained paraffin-embedded mouse skin sections. Scale bar, 100 µM. Source data are provided as a Source Data file
