Heterozygous SOD1 deficiency in mice with an NZW background causes male infertility and an aberrant immune phenotype

New Zealand white (NZW) mouse is a mutant strain that has a larval defect in the immune system, and a F1 hybrid between NZW and New Zealand Black mouse spontaneously develops systemic lupus erythematosus (SLE). In meantime, the ablation of superoxide dismutase 1 (Sod1) causes autoimmune haemolytic anaemia, a clinical condition of SLE, in mice with a C57BL/6 background. On the basis of our previous studies, we hypothesised that oxidative stress...
