The spontaneous in vitro production of anti-DNA and anti-RNA by peripheral blood mononuclear cells (PBMC) from patients with systemic lupus erythematosus (SLE) and from normal subjects was evaluated employing sensitive solid-phase assays that are specific for these antibodies. PBMC from SLE patients produced more IgG anti-DNA and anti-RNA than did normal PBMC (P <0.01). In vitro production of IgG anti-DNA appeared to correlate with serum DNA bindings (r = 0.72, P <0.005). Similar amounts of IgM anti-DNA and anti-RNA were produced by both SLE and normal PBMC. However, IgM anti-DNA antibodies always appeared to be directed against determinants on denatured DNA. Only PBMC from SLE patients produced IgG antibodies to native DNA.
