该药的两大亮点除了靶点是PD-L1,更重要的是单域单抗,又称纳米抗体(nanobody)或重链抗体(heavy chain antibody,hcAb)。 与传统抗体不同的是,单域单抗的体积约为传统抗体的1/10且仅由重链构成,其抗原结合区仅是一个通过铰链区与Fc区连接的单结构域,而且这个抗原结合区自抗体上分离后仍具有结合抗原的功能,这就...
今天就让陈老湿通过康宁杰瑞和上海交通大学药学院共同发布的《Structural basis of a novel PD-L1 nanobody for immune checkpoint blockade》这篇文章给大家介绍一下纳米抗体KN035在结构学方面的研究(KN035与PD-L1复合物的解析度1.7Å水平)。 总体结构学分析: 下图展示了KN035和PD-L1的晶体复合物。可见,KN035的...
We provided compelling evidence for the involvement of the PD-1/PD-L1 pathway in the acute infection caused by SFTSV, while demonstrating the potent inhibitory effect of our novel anti-PD1 nanobody, NbP45, against SFTSV infection in vitro and in SFTSV-infected NCG-HuPBL mouse model.During ...
[0111]如本文所用,术语“单域抗体”、“VHH”、“纳米抗体(nanobody)”、“单域抗体”(single domain antibody,sdAb, 或纳米抗体nanobody)具有相同的含义并可互换使用, 指克隆抗体重链的可变区, 构建仅由一个重链可变区组成的单域抗体(VHH), 它是具有完整功能的最小的抗原结合片段。通常先获得天然缺失轻链和重...

T细胞接合体(T cell engagers,TCEs)已被确立为治疗血液系统恶性肿瘤的一种新兴方式,但实体肿瘤仍然难治性。然而PD-1的上调与T细胞功能障碍相关,从而导致肿瘤介导的免疫抑制。 今天学习一篇文章,关于一种新的nanobody-based trispecifc T cell engager (Nb-TriTE),可能是克服抑制性的潜在策略。
The present invention provides multispecific molecules, e.g., comprising more than one ISVD or Nanobody, that bind to PD1 and CTLA4. These molecules have been engineered so as to reduce the incidence of binding by pre-existing antibodies in the bodies of a subject administered such a molecule...
Anti-PD1 nanobodyTumor-targeted deliveryImmune activationBacterial antitumor therapy has great application potential given its unique characteristics,including genetic manipulation, tumor targeting specificity and immune system modulation. However,the nonnegligible side effects and limited efficacy of clinical ...
The present invention provides multispecific molecules comprising, for example, more than one ISVD or Nanobody that bind to PD1 and CTLA4. These molecules have been genetically modified to reduce the occurrence of binding by pre-existing antibodies in the body of a subject administered such ...
