Next to demonstrating the role of FcγRIII+ NK cells in kidney transplant rejection, our study also identified the main subsets of monocytes, macrophages, and dendritic cells in kidney allografts: CD14+ classical monocytes, CD14+ FcγRIII+ intermediate monocytes, CD14- FcγRIII+ nonclassical monocytes, CD68+ macrophages and CD163+ macrophages but also CLEC9A+ cDC1 and CLEC10A+ cDC2. The gene discussed is MPPE1; the disease is medical procedure.
