The hematopoietic compartment is sufficient for lupus development resulting from the POLB-Y265C mutation.

Systemic lupus erythematosus is a chronic disease characterized by autoantibodies, renal and cutaneous disease, and immune complex formation. Emerging evidence suggests that aberrant DNA repair is an underlying mechanism of lupus development. We previously showed that the POLBY265C/C mutation, which results in development of an aberrant immune repertoire, leads to lupus-like disease in mice.
