In addition to the anti-inflammatory potential of sialylated murine IgG1, only galactosylation of murine IgG1 has also induced inhibitory signals in a mouse model of autoimmune hemolytic anemia and via crosslinking the C-type lectin receptor Dectin-1 (Clec7a) with the inhibitory receptor FcγRIIb (Figure S2 in Supplementary Material) (12, 34, 56). Here, CLEC4D is linked to autoimmune hemolytic anemia.
