Appears that there are 5 types of eosinophils
Complement Eosinophils : C1q, C3b/C4b, iC3b receptors : Bacteria : granulation
GM-CSF Eosinophils : Low affinity cd32 FcgammaR2 (IgG receptor) : vacuole Bacteria : granulation
il-5 Eosinophils : cd89 Fc alpha R1(IgA receptor) : Parasites: granulation
il-3 Eosinophils : Fc epsilon R1 (IgE receptor) high affinity:
Fc epsilon low affinity receptor
Viral Eosinophils that contain RNases
il-4 seems involved with antigens outside of the house cell while il-13 seems involved with antigens of the cytosol (visible parasite vs. one that moves into the cytosol of the host cell.
Do the Macrophages clean up the IgE antibodies?

Do Platelets? They appear to have storage pools if IgE

Hypothesis: Platelets clean up IgE
