PURPOSE CD93 is receiving renewed attention as a biomarker of inflammation. We aimed to evaluate the potential for serum sCD93 to serve as a novel biomarker for allergic inflammation. MATERIALS AND METHODS We enrolled 348 subjects with an allergic disease [allergic rhinitis (AR), chronic spontaneous urticaria (CSU), or bronchial asthma (BA)], including 14 steroid-naïve BA patients who were se...

Because of its susceptibility to apoptosis upon Ag receptor cross-linking and lack of IgD expression, cells of the mouse cell line WEHI-231 have been classified as immature B cells. In this study we show that early freezings of the WEHI-231 line express IgD but not CD93, which classifies the cells as more similar to mature B cells. Another, later line obviously has differentiated in culture and...
