title: Anti-Ro/SSA associated recurrent annular erythema: autoimmune response to recombinant 60- and 52-kDa Ro/SSA proteins.
abstract: Recurrent annular erythema associated with anti-Ro/SSA antibody response has recently been recognized as a distinct clinical entity. Serum samples from 15 anti-Ro/SSA positive patients with recurrent annular erythema were tested by enzyme-linked immunosorbent assay (ELISA) for reactivity with full-length recombinant human 60-kDa and 52-kDa Ro/SSA proteins. All the 15 sera were positive for anti-60-kDa Ro/SSA, and 11 sera (73.3%) contained anti-52-kDa Ro/SSA. These results suggest the importance of 60-kDa polypeptide component of the Ro/SSA particle as a potential target in anti-Ro/SSA associated annular erythema.
