Novel clearance mechanisms of platelets

WebThe FcγRIIA/CD32A is mainly expressed on platelets, myeloid and several endothelial cells. Its affinity is considered insufficient for allowing significant binding of monomeric IgG, while its H131R polymorphism (histidine > arginine at position 131) influences affinity for multimeric IgG2. Platelet FcγRIIA has been reported to contribute to IgG-containing … WebApr 13, 2024 · The concept of cancer immunoediting was first introduced by Schreiber in 2002; after years of research and revisions, the present theory of cancer immunoediting was finally developed [].This theory suggests that the immune system can paradoxically inhibit or promote the formation of tumor tissue, and this process is regulated in a complex …
