Interferon pathway in SLE: one key to unlocking the mystery of the disease

L Rönnblom, D Leonard - Lupus science & medicine, 2019 - lupus.bmj.com
SLE is characterised by an activation of the interferon (IFN) system, which leads to an
increased expression of IFN-regulated genes. The reasons behind the IFN signature in SLE …
