CD200R expression in the TME of NB. a CD200R expression in different immune cell subsets in NB tumors. Flow cytometry was used to determine CD200R expression. Dotted thin lines represent isotype control, while thick lines represent CD200 staining. b Summary of CD200R expression in different subsets of immune cells. Mean fluorescence intensity (MFI) of CD200R in different immune cell subsets from five NB tumors was used for the analysis. **p < 0.01, ***p < 0.001 by Mann–Whitney U test
