目前，正在开发中的双/多特异性抗体形式已有100多种。在临床开发中的双特异性抗体中，Fc-null IgG或无Fc形式占大多数。这是因为业界越来越多地意识到，双抗中Fc效应功能会导致临床开发的复杂性和潜在安全性风险。首个上市的双特异性抗体之一Blinatumomab（Blincyto®）就是一种无Fc的BiTE，靶向CD3和CD19，用于治...

To do so, we used a humanized version of mAb 2C7 specific for the gonococcal lipo-oligosaccharide (LOS) containing IgG1 Fc (Humab 2C7) that has been shown to induce complement-mediated killing of N. gonorrhoeae in mice49. While the REW, D270A/K322A (DAKA; complement null) and WT...
第二篇还没看,现在去看。多谢!//@TfR1lyxxx快乐鼠鼠:回复@通往春天的地下铁:我之前有写过,“为什么是康方生物的双抗?免疫治疗:从单靶点单抗到联合治疗再到双抗”网页链接,和“免疫检查点抑制剂抗体药物IgG类型的选择——康方生物不一样的答案”网页链接,可以看看。
IgG3-sensitized erythrocytes inhibited lgG 1-induced lysis, suggesting that each subclass engages the same Fc纬R receptor but that lysis requires a further 'signal' that the 1gG3 molecule can not deliver. Two monoclonal 1gG3 anti-D antibodies were shown to have higher binding (two times) ...
The low-affinity receptor for IgG (human FcgammaRIIIA) is selectively expressed by a subset of T lymphocytes, NK cells, and macrophages. To understand the mechanisms underlying this pattern of cell type-specific expression, we initially identified alternative promoters, Pmed1/2 and Pprox, in th...
Fc domain variants with differential FcγR binding affinity were generated through the introduction of amino acid substitutions at the hinge proximal region of the CH2 domain of human IgG1. a, The positions of the mutated residues for the different Fc domain variants are highlighted. b, The affi...
FcγRIIB is an inhibitory Fcγ receptor that binds the Fc portion of its ligand IgG. The best known function of FcγRIIB is to regulate serum Ab levels via a negative feedback loop, inhibiting B cells when sufficient Abs are made.12,13 When FcγRIIB and BCR are co-engaged by ICs,...
