PBMC analysis identified upregulation of proinflammatory genes (CXCL2, CXCL3, DEFA3, EMP1, HBD, SMAD7, SPRR1B) and downregulation of genes (CD246, KLHL34, MCF2L‐AS1, NOG, NRCAM, RAD54B, SLC4A10, VSIG1) in DKD patients (Figure 5C,D; Supporting Information 4: Figure S4G,H). This evidence concerns the gene CXCL2 and diabetic kidney disease.
