The Scientific World Journal [27] [28] [29] , further investigation into other candidate SNPs contributing to KD morbidity is needed. Besides dendritic cells, IVIG was observed to affect many other cells, including endothelial cells, monocytes, neutrophils, and T and B cells [30] [31] [32] . The numerous effects of IVIG therapy also partly explain there not being an association of −336A/G SNP of the DC-SIGN gene with IVIG resistance in KD.
