FGG and acute kidney injury: Based on cell-specific TRAP microarray in AKI (28), we identified Fga, Fgb, and Fgg (fibrinogen α, β, and γ) production from nephrons; Il11 (IL-11) production and elevated Itga5 (integrin subunit α5) from interstitial cells; Nrarp (Notch-regulated ankyrin repeat protein) from endothelial cells; and Retnlg (resistin-like γ) from myeloid lineage cells.
