2. 1. Endogenous Type I Interferon Inducers in Systemic Autoimmune Diseases

   Author : Tanja Lövgren; Lars Rönnblom; Gunnar Alm; Maija-Leena Eloranta; Andrej Tarkowski; Uppsala universitet; []
   Keywords : Medicine; Systemic lupus erythematosus; Sjögren s syndrome; type I interferon; plasmacytoid dendritic cell; natural interferon-producing cell; immune complex; RNP; Ro SSA; La SSB; Medicin;

   Abstract : Patients with systemic lupus erythematosus (SLE) have elevated levels of interferon (IFN)-α in blood and IFN-α-producing cells in tissues. In the present thesis, we investigate the mechanisms behind the upregulated IFN-α-production in SLE and also show that the IFN-α system is activated in primary Sjögren’s syndrome (pSS), with IFN-α-producing cells in the major affected organ, the salivary glands.

4. 2. Autoantibodies in congenital heart block

   Author : Robert Klauninger; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Neonatal lupus erythematosus (NLE) affects neonates of Ro/SSA and La/SSB positive women. NLE is associated with several clinical manifestations including skin rash, cytopenia and congenital heart block (CHB). CHB is the most severe manifestation which can develop into a lethal atrioventricular (AV) block. READ MORE

5. 3. Risk factors and comorbidity in primary Sjögren’s syndrome

   Author : Johannes Mofors; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Primary Sjögren’s syndrome is an autoimmune disease, in which the immune system targets the exocrine glands. The disease is characterized by inflammation and dysfunction of the salivary and lacrimal glands, leading to dry eyes and mouth. The etiopathogenesis of autoimmune diseases is not entirely known.

6. 4. RNA-protein complexes as autoantigens : cell and molecular biology of Ro/SSA and disease associations of anti-Ro/SSA antibodies

   Author : Nader Pourmand; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Ro SSA; Ro 52kD; Ro 60kD; p40phox; Ig classes; systemic lupus erythematosus; Sjögren s syndrome; autoantibodies; immunoblotting;

   Abstract : Autoantibodies to the Ro/SSA and La/SSB antigens are present in sera from patients with Sjögren's syndrome (SS) and systemic lupus erythematosus (SLE). The Ro/SSA autoantigen consists of a 52kD and a 60kD protein, complexed with one of four small RNAs. The La protein can also associate with the complex. READ MORE

7. 5. Risk factors for autoimmune-mediated congenital heart block

   Author : Sabrina Meisgen; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Placental transfer of maternal Ro/SSA and La/SSB autoantibodies during pregnancy is associated with conduction disturbances and inflammation in the developing fetal heart, termed autoimmune-mediated congenital heart block (CHB). Maternal Ro/SSA and La/SSB autoantibodies are the main risk factors associated with the fetal cardiac manifestations to date, however, the low recurrence rate despite persisting autoantibodies in subsequent pregnancies indicates that additional factors determine fetal susceptibility.
