A genetic accelerator hits the gas on autoimmune diseases
Date:1/16/2012

A "genetic accelerator" is responsible for the most severe cases of Lupus (systemic lupus erythemathosus), an autoimmune disease: the accelerator, called enhancer HS1.2, speeds up the activity of some critical genes of the immune system involved in the disease.

A team of Italian researchers at the Catholic University of Sacred Heart in Rome found that the enhancer HS1.2 is like the accelerator of the car and boosts the pathological immune response typical of the disease by enhancing the production of the pathological antibodies that attack the patient's body instead of defending it (autoantibodies).

Professor Gianfranco Ferraccioli, Head of the Rheumatology Unit of Rheumatology and Internal Medicine of the Catholic University led the research in collaboration with Professor Domenico Frezza at Tor Vergata University of Rome and Professor Raffaella Scorza at University of Milan and they published their results in the Annals of the Rheumatic Diseases.

The discovery could lead to more targeted and effective therapies against this complex disease, in particular against the most severe cases, Professor Ferraccioli explained.

Systemic lupus erythematosus is an autoimmune disease, that is a condition in which the patient's immune system goes haywire and begins to attack the body rather than defend it. Lupus affects about 60,000 people in Italy, with a major prevalence among females. Lupus affects so several different organs and tissues and causes a variety of symptoms, including joint pain, fever, skin rashes, hair loss, Raynaud's disease, anemia, nephritis.

The therapies currently used are based on cortisone, anti-malarial drugs and immunosuppressants (azathioprine, mycophenolate, cyclophosphamide) and biologic drugs (rituximab, Belimumab).

But in many cases Lupus is more aggressive and so far the origin of this particular severity was quite unclear.
