A team of researchers from the University of Osaka found that cells producing IgG1 antibodies have advantages over those producing IgM antibodies, including better antigen presentation, survival, and bone marrow migration. These advantages may lead to long-term immune protection and inform the development of more effective vaccines.
A new study suggests that HLA-II peptide-binding diversity influences antibody responses and susceptibility to infections. Individuals with broader peptide-binding repertoires were more likely to show antibody responses and had a lower risk of severe infections requiring hospital care.
A team of scientists has challenged long-held assumptions about how immune recognition works, discovering that lipid molecules can be displayed to T cells in a sideways orientation. This new model allows for more flexibility in the immune system's ability to survey its environment and respond to threats.
Researchers have identified a new immune function of human M cells, which can process and present gluten antigens, suggesting a potential link to celiac disease. This discovery sheds light on gut immunity and may support future research into celiac disease diagnosis or treatment.
Scientists at the Institute for Systems Biology have discovered how T cells respond to infections like COVID-19, revealing a predictable pattern based on genetic interactions. This breakthrough could lead to improved treatments and vaccine strategies for diseases such as cancer and autoimmune disorders.
Researchers found that neoself-antigens, presented on MHC-II, induce an immune response and lead to autoimmunity in lupus patients. EBV reactivation increases the presentation of these antigens, triggering T cell activation and autoimmune disease development.
A recent study has elucidated the genetic factors involved in systemic lupus erythematosus (SLE) development. The researchers found that HLA-DRB1*15:01 is primarily associated with SLE development in the Japanese population, suggesting its role in influencing disease progression. Furthermore, the study highlights the importance of anal...
A new study found that the antibody-drug conjugate STRO-001 showed nanomolar cytotoxicity in 88% of cancer cell lines tested, with potent efficacy against proliferating B cells. The research supports ongoing clinical studies for patients with B-cell non-Hodgkin lymphoma.
Researchers from Nara Institute of Science and Technology found that alveolar macrophages act as antigen-presenting cells to prime CD8+ T cell expansion in the lungs. This process involves the production of interleukin 18, leading to the development of resident memory-type cell populations.
