Artistic 3D

Caption

Artistic 3D of a mast cell (in the center of the picture) with IgE antibodies (in blue), which bound to the receptor Fc?RI (in pink) on the cell surface and Staphylococcus aureus bacteria (in gold). The IgE antibodies were induced during an earlier S. aureus infection and recognize bacterial toxins (in green). Upon re-infection with S. aureus (as shown) the IgE antibodies increase the mast cell response to S. aureus toxins (in green), leading to enhanced release of mast cell granules (in red) and antibacterial activity
