    Previous studies have shown that lipid peroxidative processes may play a role in disease pathogenesis in lupus-prone MRL/lpr mice. Studies were thus performed to determine if an immune response against malondialdehyde (MDA), a highly reactive byproduct of lipid peroxidation, was present in these mice. By using MDA-modified mouse serum albumin (MSA) as antigens in ELISA, we found that these mice produce high levels of MDA-specific antibodies in the complement-fixing IgG2a and IgG2b subclasses. Anti-MDA antibodies were also found in MRL/+ mice but in significantly lower levels. The specificity of these antibodies was verified by inhibition ELISA. MDA may contribute to disease pathogenesis in these mice by altering the immunogenicity of self molecules, eliciting an immune response and forming immune complexes that may deposit in tissues.
