    Objective: To determine the extent to which the gut microbiome contributes to systemic autoimmunity in a mouse model of lupus


    Objective: To determine the extent to which the gut microbiome contributes to systemic autoimmunity in a mouse model of lupus


    We generated germ -free (GF) lupus-prone BXD2 mice that spontaneously produce germinal center (GC) and high titers of serum autoantibodies under normal conditions .


    In 6 -month-old mice, GF status did not affect splenomegaly, GC B cells, age-related B cells, or serum autoantibody levels, with the exception of IgG anti-histone


    The findings suggest a model in which genetics plays a leading role in determining the initial development of autoimmunity
