Supernatants from MH-S cells increase chemotaxis of murine promyelocyte MPRO cells in a CCR1 dependent manner. MPRO cells were tested for chemotaxis towards control medium (CM), human CCL3 (20 ng/ml) and supernatants from MH-S cells (16 h) challenged with LPS (1 μg/ml) or infected with MVA or VACV WR at an MOI as indicated using a 96-well Multi-Screen-MIC plate with a 5 μm pore-sized filter (Millipore). 75.000 cells were placed in the upper part and cells migrated into the lower part were counted after 3 h. Where indicated MPRO cells were pre-incubated with 20 nM of the CCR1 antagonist J 113863 for 5 min prior to running the assay. Data are means ± SD (n = 3).
