immune system
• IgE monoclonal anti-DNP antibody primed mast cells are incapable of significant degranulation unlike similarly treated wild-type cells
• however, cells exhibit normal
• osteoclasts exhibit impaired bone remodeling compared with wild-type cells
• mice are resistant to IgE-mediated anaphylaxis unlike wild-type mice

nervous system
• oligodendrocyte precursor cells fail to differentiate in the presence of IgG or anti-Fcrg antibodies unlike wild-type cells

skeleton
• osteoclasts exhibit impaired bone remodeling compared with wild-type cells
• metaphyseal bone trabecules are irregularly distributed compared to in wild-type mice

hematopoietic system
• IgE monoclonal anti-DNP antibody primed mast cells are incapable of significant degranulation unlike similarly treated wild-type cells
• however, cells exhibit normal
• bone marrow leukocytes exhibit defective motility, progenitor cell expansion, homing, and mobilization by colony-stimulating factor (G-CSF) and increased cell adhesion compared with wild-type cells
• osteoclasts exhibit impaired bone remodeling compared with wild-type cells

cellular
• oligodendrocyte precursor cells fail to differentiate in the presence of IgG or anti-Fcrg antibodies unlike wild-type cells
• IgE monoclonal anti-DNP antibody primed mast cells are incapable of significant degranulation unlike similarly treated wild-type cells
• however, cells exhibit normal
