Systemic lupus erythematosus is an autoimmune disorder that predominantly a
ffects women during the childbearing years. Clinically, major organ systems
are affected, including the skin, kidneys and nervous system. Genetic, hor
monal, environmental and immunoregulatory factors contribute to the highly
variable expression of the disease. Impaired cellular and humoral immune re
sponses reflect disordered biochemical and molecular functions that might b
e determined genetically. Enhanced understanding of these molecular abnorma
lities should enable development of new, effective therapeutic agents in th
e near future.
