Normally the immune system protects the body from harmful bacteria and viral infections. But in autoimmune diseases, the immune system turns against the body, causing weakness, pain, and organ dysfunction, and sometimes leads to premature death.
In my laboratory, we’re working toward a better understanding autoimmune disease. In general autoimmune disease effects women much more commonly than men. For instance, 90% of lupus and Sjögren’s syndrome patients are women. That is, men are 10 times less likely to have these diseases than women. The sex chromosome are X and Y – women have two X chromosomes, while men have an X and a Y. However, we have found that men with an extra X chromosome, which occur in about 1 in 500 male births, have some autoimmune diseases at the same rate as women. In addition, women with three X chromosomes also have increased risk of autoimmune disease. We are now exploring the molecular and genetic basis by which an extra X chromosomes gives risk of autoimmunity.
We’re also looking at the genetics and immunology of both systemic lupus erythematosus, more often called just lupus, and the related Sjögren’s syndrome. We’re interested in how these diseases differently affect ethnic groups such as Native and African Americans. African Americans are more likely to have lupus and to have more severe cases of the disease, while Native Americans are more likely to have Sjögren’s syndrome. We are studying how antibodies, usually made to fight against viruses and bacteria, may cause these autoimmune diseases.
In conjunction with the US Department of Veterans Affairs, we have recently begun a project to examine autoimmune disease among those with post-traumatic stress disorder. Those with PTSD have 2 or 3 times more lupus, rheumatoid arthritis, multiple sclerosis and autoimmune thyroid disease then those with PTSD. We’re studying how the immune system is abnormal in PTSD patients.
My laboratory studies the immunology, genetics and clinical expression of the autoimmune diseases systemic lupus erythematosus and Sjögren’s syndrome. Like most autoimmune disease, lupus and Sjögren’s predominately affect women, with ~90% of patients being female. For years those interested in lupus and Sjögren’s asked why women have these diseases. A few years ago we reversed the question and asked why some men get lupus or Sjögren’s. In order to facilitate answering such a question, we collected the largest cohort of men with lupus ever assembled as well as large group of men with Sjögren’s. We found that among these men, Klinefelter’s syndrome (47,XXY, 1 in 500 live male births) was over-represented about 15-fold. Klinefelter men have an extra X chromosome; that is, are 47,XXY while normal men are 46,XY. In addition, we found that women with an extra X chromosome (47,XXX, 1 in 1000 live female births) were found more than expected by chance alone among women with these diseases. In cells with more than one X chromosome, all but one is inactivated, but this in activation is not complete in that some X chromosome genes escape inactivation. We are now studying the molecular and immunological basis of the X chromosome dose effect. These studies concentrate on genes on the X chromosome that escape inactivation and whose protein products are critical to the immune system, especially interferon production. Understanding the female bias of autoimmune disease at a fundamental level will be a critical step forward.
Antibodies are produce by the immune system against foreign invaders such as bacteria and virus. In autoimmune disease, antibodies are produced against self. We are studying how such antibodies are involved in the pathogenesis of Sjögren’s syndrome. We produced recombinant, human monoclonal antibodies from B lymphocytes purified from the salivary glands of Sjögren’s patients. In this way we can study the disease causing potential of these auto-antibodies. Our results indicate that autoantibodies are produced in the salivary glands of Sjögren’s patients. These antibodies can impair saliva production perhaps by binding muscarinic receptors. In addition, unusual glycosylation of antibodies can lead to autoimmunity.
Post-traumatic stress disorder is common in the general population and is associated with an increased risk of autoimmune diseases, including lupus, rheumatoid arthritis, multiple sclerosis and thyroid disease. In a recently started project, we are studying autoantibodies as well as B lymphocytes hyperactivity in PTSD. We hypothesize that there are immune abnormalities that predispose to both PTSD and autoimmune disease. Alternatively, PSTD might induce immune alterations that then give rise to autoimmunity. Our work should be able to distinguish these two possibilities.
Infection with Epstein-Barr virus (EBV, the causative agent of mononucleosis, may be important in the genesis of lupus and Sjögren’s syndrome. We are determining whether the Epstein Barr nuclear antigen 2 (EBNA2), a genetic transcription factor, binds to genes that increase the risk of Sjögren’s syndrome. In addition, we will determine whether EBNA2 is expression salivary gland from Sjögren’s patients. These studies should develop a pathophysiological basis by which EBV infection may be permissive for development of autoimmune disease.

News from the Scofield lab
You may never have heard of Sjögren’s syndrome, but you may very well know someone suffering from the illness. Sjögren’s (pronounced SHOW-grins) is a chronic autoimmune disease in which the body’s white blood cells attack the moisture-producing glands. The hallmark symptoms are dry eyes and dry mouth, but Sjögren’s may also cause dysfunction of other […]
In a study published tomorrow in The New England Journal of Medicine, scientists report that in patients suffering from systemic lupus erythematosus (commonly known as lupus), autoantibodies – proteins that the body mistakenly unleashes against its own tissue – are typically present years before patients are diagnosed with the disease. This research by scientists at […]
Patients who suffer with this autoimmune disease, as well as physicians who treat it, will gather in Oklahoma City Saturday, October 31 for the Ninth Annual National Conference for Sjogren’s Syndrome (NSSA). Chairman of the symposium is Morris Reichlin, M.D., Head of the Arthritis and Immunology Research Program at the Oklahoma Medical Research Foundation and […]
