Interleukin-10 (IL-10) is produced at a high level by B lymphocytes and monocytes of patients with systemic lupus erythematosus (SLE). In the present work, we analyzed whether this increased production of IL-10 contributed to the abnormal production of immunoglobulins (Ig) and of autoantibodies in SLE. The role of IL-10 was compared with that of IL-6,(More)
We have evaluated the production of PRL by human peripheral mononuclear cells (PBMNC) from normal subjects and patients with systemic lupus erythematosus (SLE). Conditioned medium prepared from basal and Con-A-stimulated PBMNC was assessed for the presence of PRL-like by its ability to stimulate growth of PRL-responsive Nb2 rat lymphoma cells. In the(More)
Some authors have found a strong statistical association of antibodies to prothrombin (aPT) with thrombosis in patients with antiphospholipid syndrome (APS); others have not confirmed this finding. It is unknown if the detection of aPT, in addition to anticardiolipin (aCL) and anti-beta2-glycoprotein-I (abeta2GP-I) antibodies, provides additional(More)
Antibodies to single-stranded R.N.A. were found by counter immunoelectrophoresis in all of 40 sera from patients with scleroderma. These antibodies were specific to the uracil bases of R.N.A. Antibodies to R.N.A. were also found in 20 of 40 sera from patients with systemic lupus erythematosus (S.L.E.), but in none of forty controls. Antibodies to R.N.A.(More)
The pattern of inheritance of autoantibodies in eight families chosen from a pool of 110 families of patients with systemic lupus erythematosus (SLE) is described. In all the eight families at least two members were already affected by SLE. In total, 19 patients and 43 first degree relatives were examined. The inheritance of a large set of antinuclear(More)
While undertaking a larger study dealing with representations of disease in pre-Columbian ceramic figures, the authors found four figures in which depression was clearly depicted. Their findings prove that psychiatric disorders did not go unnoticed by the people who inhabited the American continent before the arrival of the Spanish.
