Table 1. Transgenic/mutant mice used in the studies.

Strain name	Strain description
Fcer1g-null	lack all activating but express inhibitory FcγRIIB
Fcer1α-null	lack activating FcγRI only but express all other FcγRs
Fcgr2b-null	Lack inhibitory FcγRIIB but express all activating FcγRs
Fcgr3-null	lack activating FcγRIII only but express all other FcγRs
Fcgr4-null	lack activating FcγRIV only but express all other FcγRs
Osteopetrotic mice	mutant mice (op/op), devoid of colony stimulating factor 1, are macrophage and microglia deficient
C3-null	lack complement component C3
B4galnt1-null	express only simple gangliosides GM3 and GD3, but not complex gangliosides GM1, GD1a, GD1b or GT1b [50]
St8sia1-null	over-expresses a-series gangliosides, particularly GM1 and GD1a and do not express b-series gangliosides GD3, GD2, GD1b, and GT1b [51]

FcγRs  =  Fcγ receptors.
