Through gene analysis, researchers have found different types of interferons in systemic lupus erythematosus (SLE) tissues and cells, such as skin and synovium. The analysis, which probed 2,000 gene expression datasets from SLE patients, specifically investigated modules of genes derived from the downstream interferon gene signature. It found enriched downstream interferon signatures that were predominately from IFNB1. These interferon signatures were higher when compared with the expression of downstream interferon signatures in kidneys with lupus nephritis, according to the study, published April 23 in Nature Communications Biology.1
