“…Quantitative analysis showed that only four genes (SPP1, SERPINA1, CLU and CST3) were drastically increased in renal tubules of FGSG patients, consistent with our bioinformatic analysis with transcriptomic data. It was reported that SPP1 [ 36 , 45 , 46 ], APOE [ 47 , 48 , 49 , 50 ], SERPINA1 [ 51 , 52 , 53 ] and CLU [ 54 , 55 , 56 ] were mainly involved in innate immunity, critical for the development of FSGS [ 11 , 57 , 58 , 59 , 60 , 61 , 62 ] especially for the pathogenesnesis of tubular injury [ 63 ]. Innate immunity helps “arrest” circulating monocytes in the pathological sites [ 64 ].…”
