Researchers at Penn State College of Medicine discovered a new function of antibody-making B cells in response to flu infection. These cells produce a key signaling molecule called interleukin-1 beta, which is necessary for developing a robust immune response and forming optimal germinal centers.
Recent advancements have identified several immunomodulators with promising roles in AIH treatment, including MMF, tacrolimus, sirolimus, infliximab, rituximab, and belimumab. These agents target specific immune pathways and have shown efficacy in achieving biochemical and histological remission.
Researchers describe redundant innate immune pathways triggered by AAV vectors, including sensing of viral genome and cytoplasmic DNA sensors. The study highlights the need to understand complex biologic mechanisms underlying adverse reactions to AAV vectors in human gene therapy trials.
Researchers from Osaka University found that Csk inhibits germinal center B cell signaling, decreasing reactive oxygen species production and promoting affinity maturation. This study reveals the crucial role of Csk tyrosine kinase in regulating B cell development.
Researchers identified a type of immune cell called age-associated B cells as key drivers of lupus disease. Targeting these cells in a mouse model reduced disease progression, suggesting a potential new therapy for lupus patients.
Scientists have elucidated the exact molecular structure of an IgM-type B cell receptor, revealing its asymmetrical complex with signaling subunits. The discovery provides insights into how the receptor interacts with other molecules and could lead to a better understanding of vaccine development and lymphoma formation.
Researchers at UNC Lineberger Comprehensive Cancer Center have found a way to overcome barriers limiting cancer immunotherapies. They discovered that activating the STING protein can increase regulatory B cells, which suppress anti-cancer immunity.
Researchers have identified a potential new therapeutic approach for angioimmunoblastic T-cell lymphoma (AITL) by understanding the mechanism of its development. A team from the University of Tsukuba found that B cells accumulate mutations in genes controlling genetic material packaging, leading to AITL.
Researchers found that a single mRNA vaccine booster shot can provide the same level of protection as three doses, making it a promising investment for resource-poor countries. The study suggests that this strategy could benefit billions of people worldwide and help combat emerging COVID-19 variants.
Researchers observed an overactive B cell response in severely ill COVID-19 patients, reminiscent of systemic lupus erythematosus (SLE), which may inform treatment decisions. The findings could lead to the development of targeted therapies for patients with severe immune dysregulation.
