Study identifies genetic risk factor for rheumatoid arthritis, lupus

Researchers have identified a genetic risk factor for rheumatoid arthritis (RA) and lupus, with the STAT4 gene variant linked to increased disease risk in both conditions. The study suggests a shared disease pathway between RA and lupus, paving the way for potential new therapies targeting this pathway.

Research links genetic mutations to lupus

A recent study published in Nature Genetics has found a genetic mutation linked to systemic lupus erythematosus, a complex autoimmune disease. The discovery identifies variations of the TREX1 gene as a risk factor for developing lupus, shedding new light on its causes and potentially paving the way for new treatments.

'Nondanger' signal lowers immune reactions

Researchers have identified a well-known cell receptor that sends a 'nondanger' signal to dampen the immune system. This discovery raises the possibility of targeting this receptor to prevent overzealous immune responses in transplant patients and alleviate symptoms of autoimmune diseases like rheumatoid arthritis.

New biomarkers for lupus found

Researchers at Wake Forest University School of Medicine have identified micro-ribonucleic acids (micro-RNAs) as potential biomarkers for lupus. The study found significant differences in micro-RNA expression between lupus patients and healthy controls, with certain micro-RNAs linked to histone deacetylases and the development of lupus.

Study demonstrates safety of oral contraceptives in women with lupus

A study of 183 women with inactive or stable lupus found that taking oral contraceptives had no statistically significant difference in the occurrence of flares compared to those taking a placebo. Mild-to-moderate flares and disease complications were also similar between the two groups over a 12-month follow-up.

Lupus and the role of Epstein-Barr virus

African Americans with lupus have a higher prevalence of EBV-IgG antibodies and EBV-IgA antibodies, which increases the risk of lupus. Genetic variation in CTLA-4 also affects the immune response to EBV in lupus patients.

How lupus T cells lose IL-2

Researchers found that sera from lupus patients contain antibodies that bind to T cells and suppress IL-2 production through CaMKIV. This deficiency in IL-2 contributes to the autoantibody production seen in lupus, highlighting a new understanding of how microenvironment influences defective T cell function.

Heart-stopping antibodies

Autoantibodies disrupt calcium ion fluctuations, leading to toxic build-up and cell death in heart cells. Researchers are searching for the binding target of these antibodies to develop a new way to identify women at risk for congenital heart block.

UT Southwestern researchers locate gene family involved in determining potential for acquiring lupus

Researchers at UT Southwestern Medical Center have identified a gene family involved in determining the potential for acquiring lupus, a debilitating autoimmune disease that affects more than one million Americans. The study found that genetic susceptibility to lupus results from an imbalance between genes that increase and suppress th...

Managing lupus with prasterone

A year-long clinical trial found that prasterone improved disease activity, reduced organ damage, and boosted health-related quality of life for women with active lupus. The treatment, which is safe and effective, could offer an alternative to immunosuppressive agents or large doses of glucocorticoids.

NIH launches study of hematopoietic stem cell transplantation for severe, treatment-resistant lupus

Researchers at the NIH will conduct a clinical study to assess the safety and efficacy of hematopoietic stem cell transplantation in treating severe forms of lupus. The study aims to create a new immune system that doesn't attack healthy cells, offering hope for patients with limited treatment options.
