Why do human B cells secrete granzyme B? Insights into a novel B-cell differentiation pathway
B cells are generally believed to operate as producers of high affinity antibodies to defend the body against microorganisms, whereas cellular cytotoxicity is considered as an exclusive prerogative of natural killer (NK) cells and cytotoxic T lymphocytes (CTLs). In conflict with this dogma, recent studies have demonstrated that the combination of interleukin-21 (IL-21) and B-cell receptor (BCR)...

متن کاملHigh Serum β-Lactams Specific/Total IgE Ratio Is Associated with Immediate Reactions to β-Lactams Antibiotics
Total serum IgE result from the combination of specific and non-specific pools. High specific/total IgE ratio may reflect high level of allergen-specific IgE on mast cells. No data regarding its applications to drug allergies is available. One hundred seventy-one patients with a history of immediate reactions to β-lactams, confirmed by positive skin testing, and 122 control subjects tolerant to...

Since these antigens are mainly expressed on the surface of cytotro-phoblasts that are in direct contact with maternal tissues, it has been suggested that these molecules may have a role in induction ...
