The structural specificity of anti-phospholipid antibodies in autoimmune disease.
Antibodies to phospholipids represent a unique set of incompletely characterized antibodies prevalent in patients with systemic lupus erythematosus and related autoimmune disorders. Little is known concerning their induction and pathogenesis. Here we provide an overview of what is currently known about these antibodies and explore the possibility that they interact with and are perhaps specific for unusual lipid structures. Particular attention is given to the physical chemical nature and phase behaviour of associated putative lipid antigens. This analysis suggests that alterations in the phospholipid architecture of cell membranes may play an important role in the immunoregulation of autoimmunity.
