pubmed-article:15180766 | pubmed:abstractText | FcgammaRIIB are low-affinity immunoglobulin (Ig)G receptors that we previously demonstrated to negatively regulate IgE-induced mast cell activation when coaggregated with FcepsilonRI. Here, we engineered and characterized a bispecific reagent capable of coaggregating FcgammaRIIB with FcepsilonRI on human mast cells and basophils. | lld:pubmed |
