Sjögren’s syndrome is a chronic disease that causes the immune system to attack moisture-producing glands. Two of the most common symptoms are dry eyes and dry mouth resulting from decreases in production of tears and saliva. That may not seem serious, but for those with the disease, it greatly impacts their quality of life. Sjögren’s can lead to scarring of the corneas and can be so severe that patients produce no tears. In the mouth, lack of saliva can lead to severe cavities, broken teeth and infections. It also changes the way things taste and can make it hard to speak, eat or swallow. Sjogren’s can also affect virtually any organ in the body. Other symptoms may include common ones such as fatigue, arthritis, and neurological problems, or more rare complications such as lymphoma. The disease is common but often unrecognized and affects about 3 million Americans.
In my lab, the main goal is to understand what causes Sjögren’s syndrome and to develop new ways to treat the disease. Our work focuses mostly on identifying the genetic roots of the disease. We’ve established a clinic with doctors who perform specialized testing and gather genetic samples from patients. With a large collection of samples from Sjögren’s patients, we can perform experiments to determine which genes they have in common and find out what role those genes play in the disease.
We are also working on another part of the Sjögren’s puzzle known as gene expression. This involves comparing how genes function between people with Sjögren’s and people who don’t have the disease. Using the latest technologies, we determine which genes are active and to what level they are working. With this information, we can identify patterns of genes that are behaving abnormally and then focus on why these specific genes lead to disease.
Our work in genetics also extends to lupus, another disease in which an unbalanced immune system gets confused and turns against a person’s own body. By doing large-scale screens of lupus patients’ DNA, we can identify common genes and how they’re related to the disease. Our goal, as with Sjögren’s, is to use this information to help devise better ways to treat patients suffering from this debilitating disease.

My laboratory is primarily interested in identifying and characterizing genes that predispose to systemic lupus erythematosus (SLE) and Sjögren’s syndrome (SS). SLE and SS are complex rheumatic autoimmune diseases caused by the joint action of multiple genes and influenced by environmental factors. We use multidisciplinary approaches to study SLE and SS that draw on tools and concepts from immunology, genetics, biostatistics, bioinformatics, molecular biology, biochemistry, and microbiology to understand the underlying disease mechanisms.
Sjögren’s syndrome is a common, chronic, systemic disorder in which immune responses preferentially target moisture-producing glands. Dysfunction of salivary and lacrimal glands leads to the common symptoms of dry eyes and dry mouth, although multiple organ systems can also be involved and cause significant morbidity. SS may occur alone (in about 50% of patients) or in conjunction with other rheumatic autoimmune diseases such as SLE or rheumatoid arthritis. One major focus in our lab is to characterize gene expression profiles in SS using microarray technology. This powerful approach allows us to monitor the expression of thousands of genes simultaneously and identify key molecular pathways that are disregulated in patients compared to healthy controls. These studies clearly show that activation of interferon-inducible pathways are important in SS. Current studies are aimed at identifying additional pathways associated with SS and definung correlations with important clinical manifestations. A related goal is to identify genetic polymorphisms that contribute to disregulation of these pathways. For these studies and others, we have established an OMRF Sjögren’s Research Clinic. Patients and controls are extensively evaluated for clinical and laboratory features of SS. The comprehensive nature of data collection through this effort makes it a unique and extremely valuable resource for numerous studies in our lab and through collaborative efforts.
SLE is a systemic autoimmune disease with a wide spectrum of clinical manifestations involving inflammation in the joints, kidneys, brain, and other organs. Our lab has played a major role in a longstanding effort devoted to identifying genes involved in SLE. Recent projects include genome wide association studies using high-density single nucleotide polymorphism (SNP) analysis, fine mapping of several newly discovered SLE genes, functional studies aimed at understanding how these genes contribute to disease mechanism, and using a variety of alternative analytical approaches to expand the growing list of SLE genes.
