To investigate the potential functions of PBLD in SLE, we established the TMPD‐induced murine lupus model, one of the most commonly used murine lupus models.[28, 29] Six‐week‐old female Pbld+/+ and Pbld−/− mice were injected with TMPD, and disease progression was monitored (Figure7A). The gene discussed is PBLD; the disease is systemic lupus erythematosus.
