Eosinophils hypothesis



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
