The monoclonal antibody VM58 is directed against the CD36 antigen, a 90kD glycoprotein, also called GP IIIb expressed on human platelets. The GP IV (GP IIIb) molecule has been shown to function as thrombospondin receptor on platelets and monocytes and as receptor for Plasmodium falciparum infected erythrocytes. The monoclonal antibody reacts with platelets, monocytes, macrophages, erythroblasts and (weakly) with B-cells. In immunohistology the monoclonal antibody reacts with some endothelial cells, adipocytes and the granular layer of the skin. The antibody VM58 induces Fc-receptor-dependent platelet aggregation after binding to platelet. The heterogeneity of the response found in healthy individuals is dependent on the polymorphism of the Fc RII on platelets. |
