All protocols offered for free. 5 Fc gamma receptors belong to the group of non-catalytic tyrosine-phosphorylated receptors which share a similar signalling pathway involving phosphorylation of tyrosine residues. [26] The receptors generate signals within their cells through an important activation motif known as an immunoreceptor tyrosine-based activation motif (ITAM). [27]. 6 The Fc receptor gamma chain was initially described in the context of Fcε receptor signaling (85–88) and also contains an ITAM. FcRγ is not only important for activating cell signaling downstream of FcγRI and FcγRIII engagement (and FcγRIV in mouse), but also for the assembly and cell surface expression of the receptors (89). 7 The family of Fc receptors for IgG (FcγRs) is broadly expressed by cells of haematopoietic origin and consists of one inhibitory and several activating receptors that differ in their affinity. 8 Fc Gamma Receptors and Their Role in Antigen Uptake, Presentation, and T Cell Activation The cellular uptake, intracellular processing, and presentation of foreign antigen are crucial processes for eliciting an effective adaptive host response to the majority of pathogens. 9 Communication of IgG antibodies with the immune system is controlled and mediated by Fc gamma receptors (FcγRs), membrane-bound proteins, which relay the information sensed and gathered by antibodies to the immune system. These receptors are also glycoproteins and provide a link between the innate and adaptive immune systems. neonataler fc-rezeptor 10 dem niederaffinen Fc-gamma-Rezeptor II (FcγRII) vermittelt einen starken Effekt, während die starke Interaktion mit dem FcγRI kaum eine Wirkung zeigt. 11
