The CRC will investigate iron's potential as a building block for the future, aiming to enhance its properties and make it more affordable and resource-efficient.
A study by Tokyo University of Science researchers identifies a novel regulatory axis targeting dendritic cell activity, suppressing autoimmune disease symptoms and bone loss. They discovered DCIR binds to glycoproteins on macrophages and osteoclasts, reducing inflammation and immune responses.
A new UCL-led study found that people who survived childhood cancer have a higher risk of cardiovascular disease, infections, and disorders of the immune system by age 45. The study also suggests that cancer survivors treated with chemotherapy and radiotherapy face greater long-term health effects.
Scientists have reversed new-onset type 1 diabetes in mice by injecting pyramid-like DNA molecules called tFNAs, which increased regulatory T cells and protected pancreatic β-cells. The treatment is one of the most promising candidates for type 1 diabetes immunotherapy.
Researchers report that 90% of patients who received gene therapy between 2009 and 2012 remain disease-free, with significant immune system differences observed among those treated. The therapy is most effective in younger children, but further work is needed to achieve high levels of gene correction in all patients.
Research at Florida Atlantic University found that green sea turtles in polluted environments have impaired immune systems, leading to increased disease susceptibility. The study suggests a positive feedback loop where pollution compromises immunity, making turtles more prone to Green Turtle Fibropapillomatosis.
Researchers at UToledo have developed a protein-based vaccine that promotes a strong immune response, effectively treating rheumatoid arthritis and improving bone quality. The findings suggest long-term benefits following immunization.
A team of researchers from FAU has investigated the timing of treatment in autoimmune diseases and found that early intervention can have a major impact on disease progression. By targeting B cells, which produce autoantibodies and influence other immune cells, researchers were able to prevent or delay severe organ damage.
The FDA has granted orphan drug status to Octagam 10%, the first and only IVIg treatment for adult dermatomyositis. The therapy is expected to become the first treatment option for adults with this rare disease, which affects approximately 10 out of every million U.S. residents.
A new study examining the association between type 2 diabetes mellitus and skin diseases reveals a strong link between the two conditions.
