We selected one case from each of the four groups for multiple immunofluorescence staining, and the results showed that the infiltrating cells within the glomeruli in Cryo-GN were predominantly CD68+CD163+ cells, with a small number of CD68+CD206+ cells and CD3+ cells infiltrating, and CD68+CD86+ cells were rarely observed (Figure 4). The gene discussed is CD163; the disease is ganglioneuroma.
