Abstract

To determine if IgG fractions from sera of individuals with systemic lupus erythematosus (SLE) were toxic to cultures of whole rat embryos. Head-fold stage rat embryos (9.5 days of gestation) were cultured on media consisting of 50% rat serum containing IgG fractions isolated from plasmapheresis plasma of six subjects with SLE and six with other autoimmune diseases. Each fraction was tested at 11 mg/ml and those toxic were also tested at 7.5 and 4 mg/ml. Of the six SLE IgG fractions, four were embryotoxic (embryolethal or teratogenic) while only one of the six non-SLE fractions were embryotoxic. IgG fractions from subjects with SLE can be toxic to cultures of whole rat embryos in the absence of maternal tissues or influence. Such cultures of whole embryos may be useful to identify those antibodies that represent a risk for fetal loss as well as to understand their mechanisms of embryotoxicity.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
