Incomplete antigenic cross-reactivity between platelets and megakaryocytes: relevance to ITP.

abstract：:Receptors for the Fc portion of IgG (FcγRs) are mandatory for the induction of various IgG-dependent models of autoimmunity, inflammation, anaphylaxis, and cancer immunotherapy. A few FcγRs have the ability to bind monomeric IgG: high-affinity mouse mFcγRI, mFcγRIV, and human hFcγRI. All others bind IgG only when aggr...
