Subsequently, we attempted to perform immunohistochemistry (IHC) staining for NRGs (CYBB, ITGB2, ITGAM, LILRB2, TLR2, and TLR7) in kidney sections from ANCA-GN patients and age- and sex-matched ccRCC patients with adjacent non-tumor tissues. Here, LILRB2 is linked to nonpapillary renal cell carcinoma.
