Increased antibody production upon stimulation with Zymosan or HKCA hyphae is not dependent on dectin-1 or specific B cell receptor recognition. Splenic B cells from Dectin-1-/- and Dectin-1+/+ mice (A, B) and B1-8ftg/tg and B1-8f+/+ mice (C, D) were cultured unstimulated or stimulated with LPS+IL-4 or anti-CD40+IL-4 in the presence of Zymosan, HKCA yeast or HKCA hyphae. After 5 days of culture, the percentage of IgG1-positive cells within live B cells was measured by flow cytometry (A, C), and the concentration of secreted IgG1 was measured by ELISA (B, D). Data represent mean ± SEM of 3 mice, with triplicate measurements performed for each mouse. *p < 0.05, **p < 0.005.
