My 101
My lab seeks to increase the understanding of basic disease processes using immunologic approaches. By uncovering the cellular and molecular basis of disease, we can take rational approaches to development of effective therapies. In the rheumatic disorder Sjögren’s syndrome (SS), we are applying new molecular tools to an old problem. Sjögren’s syndrome is a systemic rheumatic disease that selectively targets the moisture-producing salivary and lacrimal glands. Patients with Sjögren’s disease often have painful dry mouth and eyes, severe dental caries, fatigue, and arthritis. Why the salivary and lacrimal glands are involved in the disease process is a long-standing mystery. We are using single-cell molecular approaches to discover the substances and immune mechanisms that are causing the abnormal immune reactions occurring in salivary gland tissue from patients with SS.

Sjögren’s syndrome (SS) is a systemic rheumatic disease that selectively targets the moisture-producing salivary and lacrimal glands. Patients with SS often have painful dry mouth and eyes, severe dental caries, fatigue, and arthritis. Why the salivary and lacrimal glands are involved in the disease process is a long-standing mystery. Our group is seeking to discover the substances and immune mechanisms that are causing the abnormal immune reactions occurring in salivary gland tissue from patients with SS. The approach we are using is to study gene expression of single immune cells isolated from salivary gland biopsy tissue from people who have SS. We are using lymphocyte receptors from the affected biopsy tissues to discover the substances, or antigens, causing their activation. So far, our work has identified a link between increased T helper cell clonal expansion, reduced salivary flow, and increased salivary gland damage.
Bacillus anthracis is a common organism occurring in the soil that can cause disease in farm animals. Unfortunately, spores from this organism, if inhaled into the lungs, can cause fatal disease in humans. An important risk of exposure in the modern world is bioterrorism. While vaccination and antibiotics are effective for preventing serious human disease, better therapeutic approaches are needed to improve the survival rates if people become sick through inhalational exposure. Our group has discovered that this bacterium can inhibit one of the most important functions of macrophages: disposal of dead cells. Chronic impairment of this process is well known for promoting autoimmune responses in autoimmune diseases like lupus and SS. We think that impairment of this process during bacterial infections of the blood may amplify inflammation, leading to or worsening a potentially fatal complication known as sepsis. We are currently identifying the molecular mechanisms that Bacillus anthracis uses to inhibit the disposal of dead cells and seeking ways to counteract these effects.

News from the Farris lab
When a team of OMRF scientists set out to improve the anthrax vaccine, they started with a theory everybody thought would work: Break apart the toxins so they can’t enter cells. Problem solved. But things don’t always work as expected. In fact, the theory doesn’t work at all, according to a paper by OMRF’s Darise […]
A new study from OMRF has discovered that lurking in the bodies even of healthy people are numerous rogue immune cells, the cause of rheumatoid arthritis and a host of other diseases. The new findings could be key to developing new ways to prevent and treat autoimmune diseases, conditions like rheumatoid arthritis, lupus and type […]
Connor Fullenwider, a 2005 graduate of Muskogee High School, will spend his summer vacation as a Presidential Scholar at OMRF. Fullenwider, currently a sophomore at the United States Naval Academy in Annapolis, Md., will complete a research project focused on the study of anthrax under the guidance of Darise Farris, Ph.D., in OMRF’s Arthritis and […]
Nearing the mid-point of an historic five-year research project, the Oklahoma Medical Research Foundation announced today that it is making important strides toward developing more effective vaccines and treatments for the deadly infectious disease anthrax. In a study involving 120 military personnel, Judith James, M.D., Ph.D., Sherry Crowe, Ph.D., and Darise Farris, Ph.D., have identified […]
Oklahoma Medical Research Foundation scientist John Harley, M.D., Ph.D., has been named the inaugural recipient of a mentoring award from the nation’s leading rheumatology organization. Harley will be honored in Washington D.C. during the 70th Annual Scientific Meeting of the American College of Rheumatology (ACR) Research and Education Foundation. The new Excellence in Investigative Mentoring […]
