Maternal immunization with OVA upregulates FcγRIIb expression on B cells from offspring. BALB/c offspring from mothers immunized with OVA prior to conception or from control mothers (nonimmunized) were immunized (3 d-o) or not with OVA and evaluated at 3 d-o and 20 d-o for FcγRIIb expression on splenic B cells (B220+IgM+). The data obtained by flow cytometry represent the mean ± SEM of 12 mice per group. Histogram of B cell FcγRIIb expression depicting the cells from offspring from immunized (shaded histogram, Mean fluorescence intensity (MFI) in bold numbers) and nonimmunized mothers (white histogram, MFI in light numbers). * P ≤ 0.05 compared to offspring from nonimmunized mothers, # P ≤ 0.05 compared to nonimmunized offspring (20 d-o) from control mothers.
