2023年12月1日 · The C-C motif chemokine receptor 8 (CCR8) is a class A G protein-coupled receptor (GPCR) that is highly enriched and selectively expressed on intratumoral regulatory T...
Unveiling the structural mechanisms of nonpeptide ligand …
2024年2月2日 · Understanding the molecular recognition of CCR8, particularly with nonpeptide ligands, is valuable for drug development. Here, we report three cryo–electron microscopy structures of human CCR8 complexed with G i trimers in the ligand-free state or activated by nonpeptide agonists LMD-009 and ZK 756326.
Differential expression of CCR8 in tumors versus normal tissue …
CCR8 expression is higher in primary tumors than in normal adjacent tissues and significantly higher than in peripheral Tregs and both tumor and peripheral CD4 + T conventional cells. We also show that, on a per-cell basis, tumor Tregs have the highest number of CCR8 molecules compared to any other T cell subsets.
Biological characterization of ligands targeting the
2021年6月1日 · Targeting CCR8 has shown therapeutic potential in several preclinical studies for autoimmune disease and cancer. Activation of CCR8 in Treg cells by a CCL1-Ig fusion protein suppresses disease progression in an experimental model for multiple sclerosis (i.e. experimental autoimmune encephalomyelitis, EAE) [38].

CCR8——肿瘤免疫领域的一颗新星 - 知乎 - 知乎专栏
今年5月份,BMS就CCR8靶向性单克隆抗体BMS-986340启动了一项新的1/2期临床,评估其与 O药 联用对多种实体瘤的治疗效果。 这是全球第一款正式开启临床研究的CCR8靶向性抗体药物。 而就在去年的9月1日, 吉利德 宣布从Jounce Therapeutics公司获得CCR8靶向性抗体JTX-1811的合作开发权。 目前,该项目已经获得了FDA的临床试验许可。 一时间,CCR8这个曾长时间几乎无人问津的靶点走到了抗肿瘤新药研发的前沿。 CCR8是 趋化因子受体 亚家族的成员,属 …
重大进展!沃臻生物已成功解析明星靶点CCR8和GPRC5D三维原子 …
2023年8月1日 · 沃臻生物最新发布的MegaR技术能够有效增大GPCR的分子量,且无需使GPCR处于激动状态,从而为 GPCR-拮抗剂复合物或者GPCR-反向激动剂复合物的高分辨率冷冻电镜结构解析提供了基础。 另外,MegaR技术通过基因工程技术在GPCR上融合长度仅为30个氨基酸的标签,最大限度地降低了融合标签对GPCR天然构象的影响。 “融合标签不会与GPCR的跨膜螺旋形成刚性结构,保证了改造后的 GPCR蛋白跨膜螺旋和膜外结构域的天然折叠”。 经MegaR技术改 …
