The relevance of antigen binding to the pathogenicity of lupus autoantibodies
Michael P Madaio, Michael P Madaio
Abstract
Although lupus autoantibodies provide diagnostic value, discordance between serum levels and nephritis poses mechanistic questions. Krishnan and co-workers report that only those that crossreact with basement membrane components produce immune deposits. Thus, other glomerular binding properties probably define where deposits form. Thereafter, Fc- and complement-mediated events influence disease expression. Clearly other factors determine the ultimate phenotype; however, the findings provide insights into the variable disease patterns in lupus nephritis.
