ANTINEUTROPHIL CY TOPLASMIC AUTOANTIBODIES IN SYSTEMIC LUPUS ERYTHEMATOSUS

Antineutrophil cytoplasmic autoantibodies (ANCA) were first described in patients with necrotizing glomerulonephritis. The original observation passed unnoticed until an association was made between ANCA and active Wegener's granulomatosis. Since then, tremendous progress has been made in elucidating the association between ANCA subtypes and clinicopathologic syndromes, and the potential p...

Generation and Evaluation of Monoclonal Autoantibodies in Systemic Lupus Erythematosis

Three murine monoclonal anti-ssDNA autoantibodies have been produced by fusion of spleen cells from NZB/NZW F1 hybrid mice with Sp2/0-Ag 14 murine myeloma cells. Specificity studies characterizing monoclonal anti - ssDNA autoantibodies revealed binding patterns for nucleotides. Clone E-4-1 showed preferential binding with mono-di-and polyguanosine. Clones E-4-4 and E-11-1 specitically bound mon...

Lots of autoantibodies equal lupus?

Autoantibodies may be found years before an autoimmune disease becomes clinically apparent. For systemic lupus erythematosus (SLE), those to RNA-binding proteins, to phospholipids, and to double-stranded DNA, in particular, have been found in sera of SLE patients years before the diagnosis was made. New data now show in an unbiased way that, in patients with early SLE, no single antibody class ...

Autoantibodies against C1q in systemic lupus erythematosus.

Do we need new autoantibodies in lupus?

Systemic lupus erythematosus (SLE) is a clinically and serologically complex disease that demonstrates clinical, epidemiological and genetic differences among racial and ethnic groups. Some autoantibodies are useful for diagnosis of the illness. Others are clinically important because of associations with a particular manifestation of SLE. Antibodies to RNA helicase A (anti-RHA) comprise a newl...
