1. Signaling through the inhibitory Fc receptor FcγRIIB induces CD8 T cell apoptosis to limit T cell immunity
Anna B. Morris,et al.Immunity. 2020.PMCID: PMC7326381
“Effector CD8+ T cells are important mediators of adaptive immunity, and receptor-ligand interactions that regulate their survival may have therapeutic potential. Here, we identified a subset of effector CD8+ T cells that expressed the inhibitory Fc receptor FcγRIIB following activation and multiple rounds of division. CD8+ T cell-intrinsic genetic deletion of Fcgr2b increased CD8+ effector T cell accumulation, resulting in accelerated graft rejection and decreased tumor volume in mouse models. IgG antibody was not required for FcγRIIB-mediated control of CD8+ T cell immunity, and instead, the immunosuppressive cytokine Fgl2 was a functional ligand for FcγRIIB on CD8+ T cells, in that Fgl2 induced caspase 3/7-mediated apoptosis in Fcgr2b+ but not Fcgr2b−/− CD8+ T cells. Moreover, Increased expression of FcγRIIB correlated with freedom from rejection following withdrawal from immunosuppression in a clinical trial of kidney transplant recipients. Together, these findings demonstrate a cell-intrinsic coinhibitory function of FcγRIIB in regulating CD8+ T cell immunity.”

2. Accelerated clearance and degradation of cell free HIV by neutralizing antibodies occurs via FcγRIIb on liver sinusoidal endothelial cells by endocytosis
James M. Turman,et al.J Immunol. 2021.PMCID: PMC7946731
“Neutralizing antibodies suppress HIV infection by accelerating viral clearance from blood circulation, in addition to neutralization. The elimination mechanism is largely unknown. We determined that human liver sinusoidal endothelial cells (LSEC) express FcγRIIb as the lone Fc gamma receptor, and, using humanized FcγRIIb mouse, we found that antibody-opsonized HIV pseudoviruses (Ab-HIV) were cleared considerably faster from circulation than HIV by LSEC FcγRIIb. Compared to humanized FcγRIIb expressing mice, HIV clearance was significantly slower in FcγRIIb KO mice. Interestingly, pentamix of neutralizing antibodies cleared HIV faster compared to polyclonal HIVIG, though the HIV antibody-antigen ratio was higher in immune complexes made of HIVIG and HIV than pentamix and HIV. The effector mechanism of LSEC FcγRIIb was identified to be endocytosis. Once endocytosed, both Ab-HIV and HIV localized to lysosomes. This suggests that clearance of HIV, endocytosis and lysosomal trafficking within LSEC occur sequentially, and that the clearance rate may influence downstream events. Most importantly, we have identified LSEC FcγRIIb-mediated endocytosis to be the Fc effector mechanism to eliminate cell free HIV by antibodies, which could inform development of HIV vaccine and antibody therapy.”

3. Plasmacytoid Dendritic Cells Take Up Opsonized Antigen Leading to CD4+ and CD8+ T Cell Activation In Vivo
Pia Björck,et al.J Immunol. 2008.PMCID: PMC2884144
“Plasmacytoid dendritic cells (pDC) are the body’s main source of IFN-α, but, unlike classical myeloid DC (myDC), they lack phagocytic activity and are generally perceived as playing only a minor role in Ag processing and presentation. We show that murine pDC, as well as myDC, express Fcγ receptors (CD16/CD32) and can use these receptors to acquire Ag from immune complexes (IC), resulting in the induction of robust Ag-specific CD4+ and CD8+ T cell responses. IC-loaded pDC stimulate CD4 + T cells to proliferate and secrete a mixture of IL-4 and IFN-γ, and they induce CD8+ T cells to secrete IL-10 as well as IFN-γ. In contrast, IC-loaded myDC induce both CD4+ and CD8+ T cells to secrete mainly IFN-γ. These results indicate that pDC can shape an immune response by acquiring and processing opsonized Ag, leading to a predominantly Th2 response.”

背景知识

重组2.4G2抗体（2.4G2抗体、抗小鼠CD16 / CD32单抗2.4G2）与小鼠CD16（FcγIII）和CD32（FcγII）受体蛋白结合。一些商业Fc封闭试剂的主要成分即为2.4G2抗体。大鼠、小鼠和人IgG Fc可与小鼠CD64（FcγI）结合。因此，重组2.4G2抗体可用于在流式细胞术、免疫组化、免疫沉淀和封闭实验中阻断IgG与小鼠Fc受体的非特异性结合。客户可根据自身应用选择不同的IgG同型。

最常用的小鼠Fc封闭试剂包括：

抗小鼠CD16/CD32（克隆2.4G2）：用于流式细胞术、免疫组化（IHC）和免疫沉淀（IP）。它对FcγRII（CD32）和FcγRIII（CD16）具有高度特异性，可降低背景染色；但可能无法封闭所有Fc受体。克隆X54-5/7.1是流式细胞术和功能实验中最广泛使用的抗小鼠FcγRI（CD64）克隆，可防止单核细胞、巨噬细胞和树突状细胞上的非特异性Fc受体结合，提高抗体特异性。

正常小鼠血清、从小鼠血清中纯化的小鼠IgG或小鼠同型对照混合物：用于IHC和免疫荧光（IF）中的一般Fc封闭。价格便宜、使用方便，但特异性较低，甚至可能引入不需要的免疫球蛋白。我们的重组小鼠IgG抗体混合物价格实惠；各种IgG的比例经过优化且可调整，不含任何不需要的免疫球蛋白。

纯化的大鼠IgG或同型对照：用于流式细胞术。可作为封闭Fc受体的对照，但对Fc受体无特异性。悉得（Syd Labs）提供多种大鼠IgG同型对照。

牛血清白蛋白（BSA）或胎牛血清（FBS）：用于Western Blot（WB）和IHC中的一般封闭。易于获得，可减少非特异性结合，但对Fc受体封闭效果较差。

商业Fc封闭溶液：用于流式细胞术、IHC和功能实验。通常经过预优化，效果显著，但比自制溶液更昂贵。

根据应用推荐的最佳小鼠Fc封闭试剂选择：

流式细胞术：抗小鼠CD16/CD32（克隆2.4G2）。

免疫组化（IHC）和免疫荧光（IF）：正常小鼠血清、纯化的小鼠或大鼠IgG或同型对照，或商业Fc封闭试剂盒。我们的重组小鼠IgG抗体混合物和重组大鼠IgG同型对照价格实惠；各种IgG的比例经过优化且可调整，不含任何不需要的免疫球蛋白。

Western Blot和ELISA：BSA或FBS。

功能实验（例如封闭Fc介导的效应）：商业Fc封闭试剂。
