Nrp2 expression in activated macrophages during joint inflammation. A Nrp2 expression in immune cells in the CIA synovium. The hind paws of CIA-induced mice were digested and subjected to flow-cytometric analysis. The representative histograms of Nrp2 staining and the cumulative data are shown. Data are expressed as the means ± SD. N = 3 from three independent experiments. B The characteristics of Nrp2-high macrophages. The representative histograms of CD86 and MHC class II expression on joint-infiltrating macrophages (left) and their cumulative data (right) are shown. N = 6 from two independent experiments. C Nrp2 expression on BMMs. BMMs were cultured under the indicated conditions, and Nrp2 expression was determined by flow cytometry. The representative histograms and the cumulative data are shown. N = 3 from three independent experiments. D NRP2 expression in synovium-infiltrating cells in RA. The deposited single-cell RNA-seq data were reanalyzed, and several cell types were defined by UMAP. NRP2 expression is denoted by purple dots. The statistical analyses were performed using an unpaired t-test
