Patients with necrotizing myopathies who test positive for novel autoantibodies against 200-kd and 100-kd proteins may benefit from immunosuppressive therapy due to their autoimmune nature. Researchers also found a unique association between statin use and muscle symptoms in this patient group.
Researchers identify LGI1 as the main target of autoantibodies in patients with limbic encephalitis, leading to a new diagnostic test and potential therapeutic strategies for other neurological disorders. The findings also suggest that limbic encephalitis should be classified as an autoimmune synaptic encephalopathy.
Researchers found that a single species of gut-residing bacteria can trigger a cascade of immune responses leading to the development of arthritis in genetically susceptible individuals. The bacteria cause the production of autoantibodies and T cells, which trigger an autoimmune response and inflammation in the joints.
A UT student has received a $10,000 fellowship to investigate the causes and effects of pre-eclampsia, a condition that affects millions of women worldwide every year. Her research aims to find new treatments for this deadly disease, which is responsible for 18% of pregnancy-related maternal deaths annually in the US.
Researchers at NIEHS found an association between UV radiation and the frequency of dermatomyositis in women. Women with higher UV levels were more likely to develop this form of myositis, which weakens muscles and causes distinctive rashes.
A 23-year-old man developed severe autoimmune hepatitis after contracting varicella zoster virus, responding dramatically to steroid treatment. The case highlights the importance of considering AIH in patients with persistent altered liver enzymes following a viral infection.
Researchers analyzed cord blood samples of infants and siblings to identify those at high genetic risk for type 1 diabetes. A randomized controlled trial found that nasal insulin therapy did not delay or prevent the condition's development, contradicting previous mouse model results.
Researchers discovered autoantibodies to a complementary protein called plasminogen, which plays a key role in blood clotting, in patients with ANCA vasculitis. The findings suggest that protein complementarity may offer new insights into autoimmune diseases.
B cells can activate themselves in autoimmune diseases without T cell assistance, leading to a 'vicious cycle' of chronic disease. This finding may explain why treatments targeting T cells have been less effective and newer B cell-targeted therapies show promise.
Biochemists at the University of Texas Medical School have found evidence that pre-eclampsia may be an autoimmune disease, with autoantibodies activating an angiotensin receptor that causes artery constriction. This could lead to novel diagnostic and therapeutic possibilities for the condition.
Researchers have induced pre-eclampsia in mice by injecting human autoantibodies, demonstrating a potential pathway for the disorder. Blocking these autoantibodies prevented the development of pre-eclampsia in mice, suggesting a new approach to diagnosis and treatment.
Researchers found a link between high levels of adenosine and priapism in male mice with sickle cell disease. The study suggested that reducing adenosine levels or blocking its activation could provide new treatments for priapism. Additionally, two other studies explored the development of reproductive disorders in humans and the prote...
A global research alliance found associations between anti-ribosomal P antibodies and psychosis, as well as lupus anticoagulant and cerebrovascular disease in SLE patients. The study identified potential biomarkers for neuropsychiatric events, but future studies are needed to confirm these findings.
A study published in Thorax reveals a potential early warning system for lung cancer, detecting autoantibodies in blood that are associated with solid tumours and triggered by cancerous changes. The presence of these autoantibodies in patients indicates an 80% chance of a cure if the disease has not yet spread.
Researchers found a potential biomarker for preeclampsia in elevated autoantibodies, associated with increased cardiovascular risk. The study suggests these autoantibodies may also be related to high blood pressure and inflammation.
The study found that male sex influences RA mechanisms, with higher production of anti-CCP antibodies in families with affected male members. Female patients also exhibit differences in disease expression and response to treatment.
Researchers developed a new approach to predict type 1 diabetes risk by combining older and newer methods, identifying a specific protein marker associated with rapid progression. The study found that individuals positive for this marker have an 80% risk of developing the disease after just 6.7 years.
Scientists have made a significant breakthrough in understanding pemphigus, a deadly skin blistering disease. Researchers engineered antibodies that reproduce the disease in vitro and in mice, offering a new opportunity for targeted therapy development.
Recent research suggests that autoantibodies can identify individuals at risk of autoimmune diseases such as rheumatoid arthritis and diabetes. Autoantibodies were detected in healthy individuals years before the onset of symptoms, paving the way for potential preventive treatments and improved disease management.
A new study found that blocking the protein FcRn reduces autoantibody production and protects against arthritis in mice, offering a potential therapeutic target for autoimmune diseases. The research suggests that FcRn may be responsible for promoting autoimmunity in patients with conditions like lupus and rheumatoid arthritis.
Researchers found that lupus patients' autoantibodies accumulated in the blood in a predictable pattern before diagnosis, slowing down after therapy. The study's findings may help identify and monitor people at risk of developing autoimmune diseases like lupus.
A new study by Oklahoma researchers has identified autoantibodies years before the clinical features of lupus and found specific autoantibodies close to disease onset. The study, published in the New England Journal of Medicine, holds important clinical value and may lead to new therapies for the disease.
Researchers at FIRS Laboratories have identified a monoclonal autoantibody responsible for hyperthyroidism in patients with Graves' disease. This breakthrough discovery may lead to the development of new agents controlling the action of autoantibodies and treating related hormonal disorders.
Researchers found that shedding of TSHR A subunit amplifies immune response to TSHR in animal model. This discovery increases understanding of autoantibody production and hyperthyroidism in Graves disease.
Researchers have discovered that autoreactive B cells escape normal controls by proliferating and undergoing somatic hypermutation outside the germinal center, leading to the production of autoantibodies in autoimmune diseases like lupus. The study reveals a new understanding of how B cells contribute to the origins of these diseases.
Researchers discovered an autoimmune response to GAD65 enzyme leading to excess glutamate and brain damage in children with juvenile Batten disease. The study suggests immunotherapy may slow progression of the disease, which is fatal by late teens or twenties.
Researchers at Emory University found that vitamin E supplementation decreased autoantibodies associated with oxidation of lipoproteins in healthy women. The study suggests that antioxidants like vitamin E may help attenuate oxidation and reduce the risk of atherosclerosis.
