The serine-threonine protein phosphatase 2A (PP2A) enzyme is critical for regulatory T cells to function—without it, they don’t have the ability to suppress effector T cells and can’t protect against autoimmunity, according to new research published in Nature Immunology. Researchers found that conditional knockout mice—in which PP2A expression is knocked out only in regulatory T cells—developed…
New research investigates the role of autophagy, specifically the cell digestion process called LC3-associated phagocytosis (LAP), in inflammation and the pathology of systemic lupus erythematosus (SLE). Researchers found that defects in this process result in failure to digest dying cells, which increases inflammatory cytokine production and results in SLE-like disease in mice. Further exposure to dying cells accelerated disease development…
It’s been said that there is no greater bully pulpit than the American presidency. Linking the force of moral persuasion to this most powerful office—one that is capable of issuing executive orders and bypassing the wishes of Congress or rousing public opinion in favor of or against bills that are in the process of being…
NEW YORK (Reuters Health)—Disease remission in patients with rheumatoid arthritis (RA) is associated with a lower risk of developing metabolic syndrome, according to a new study from Thailand. Researchers also found that a lower educational level was linked to a higher risk of metabolic syndrome, they report in Joint Bone Spine, online May 26. Dr….
(Reuters)—A U.S. Food and Drug Administration (FDA) advisory panel recommended approving Teva Pharmaceuticals Industries Ltd’s long-acting opioid painkiller, Vantrela ER, saying data showed it reduces pain and has some abuse-resistant properties. The drug is designed for use every 12 hours for the management of pain severe enough to require around-the-clock treatment in patients who have…
NEW YORK (Reuters Health)—Bone resorption increases during pregnancy and continues to be high postpartum, according to new findings using lead testing to measure bone turnover. Researchers also found unexpected evidence that maternal lead burden is transferred to the fetus. “These data confirm calcium balance studies that indicate increased bone resorption throughout pregnancy and lactation,” Dr….
A recent study from the U.K. calculated the incidence of comorbidity associated with systemic lupus erythematosus (SLE), specifically looking for cardiovascular disease, stroke, end-stage renal failure, cancer, osteoporosis and infection. Even after adjusting for age, sex and other variables, investigators found that people with SLE have an increased global burden of comorbidity compared with the general population. Additionally, the study found that men with SLE had higher rates of cardiovascular disease, stroke and cancer, while women with SLE had higher rates of infection and osteoporosis. Overall, younger people with SLE had the greatest relative risk compared with controls…
New research confirms that patients with rheumatoid arthritis who respond to treatment experience an increase in cholesterol levels, including total cholesterol, LDL-C and HDL-C levels. However, the use of triple therapy may be important for understanding this association and mitigating its risk…
NEW YORK (Reuters Health)—Newly identified biomarkers could aid in the diagnosis of inflammatory bowel disease (IBD) and help guide therapy, Canada-based researchers report. Accurately differentiating between Crohn’s disease (CD) and ulcerative colitis (UC) is important for ensuring early and appropriate treatment. However, the conditions can’t be reliably distinguished based on clinical symptoms, site of disease,…
New research has found that the amyloid protein curli triggers immune activation and autoantibody production in lupus-prone and wild-type mice. Stefania Gallucci, MD, says these results provide insight into the mechanisms of bacterial infection that may result in lupus…
