IFNA13 and lupus nephritis: From transcriptome array datasets, median-centered log2 mRNA expression levels of IFNα (IFNA1, IFNA2, IFNA4, IFNA5, IFNA6, IFNA7, IFNA8, IFNA10, IFNA13, IFNA14, IFNA16, IFNA17, and IFNA21), IFNω (IFNW1), and IFNβ (IFNB1) in lupus nephritis were extracted specifically from microdissected tubulointerstitial (n = 32) and glomerular compartments (n = 32).
