| 产品介绍 | background: The natural cytotoxicity receptors (NCRs) are a recently characterized family of Ig-like activation receptors that appear to be major triggering receptors in tumor cell recognition. NCR1 is a glycoprotein that has two extracellular Ig-like domains followed by a ~40 amino acid residue stalk region, a type I transmembrane domain, and a short cytoplasmic tail. NCR1 has been shown to represent a novel NK cell-specific molecule involved in human NK cell activation. NCR1 has been implicated in NK cell-mediated lysis of several autologous tumor cells and pathogen-infected cell lines. Function: Cytotoxicity-activating receptor that may contribute to the increased efficiency of activated natural killer (NK) cells to mediate tumor cell lysis. Subunit: Interacts with CD247 and FCER1G Subcellular Location: Cell membrane. Tissue Specificity: Selectively expressed by both resting and activated NK cells. Post-translational modifications: N-glycosylated. O-glycosylated. Similarity: Belongs to the natural cytotoxicity receptor (NCR) family. Contains 2 Ig-like (immunoglobulin-like) domains.

文献和实验Nature:癌症疫苗新突破!调动 T 细胞与 NK 细胞的双重攻击,全面杀灭癌细胞
,MICB-vax 免疫小鼠的纯化血清 IgG 显著增强了这些共培养中 CD8+ T 细胞的增殖,抗 MICB 抗体作用下 DC 功能的增强则依赖于 DC 上 Fc 受体的激活。 图片来源:Nature 结语 综上所述,本研究报道的新型疫苗通过激活多种效应细胞群(不同的 T 细胞和 NK 细胞群)来实现肿瘤免疫。 机制层面,该疫苗诱导产生的抗体通过抑制肿瘤细胞 MICA/B 的蛋白水解,增强 NK 细胞的细胞毒性功能,还可以增加 DC 细胞将肿瘤抗原递呈给 CD8 + T 细胞。不仅如此
面,抗体的结合可以增强免疫细胞对抗原的识别和吞噬能力,进而增加免疫应答。另一方面,抗体的结合可以通过与免疫细胞表面的调节受体结合,抑制或增强免疫应答反应,帮助免疫系统在抗感染,抗肿瘤等过程中取得平衡的应答反应。 4、 抗原抗体复合物通过经典途径激活补体系统 补体系统是一种能够引起炎症和细胞溶解的蛋白质系统,IgG1、IgG2、IgG3和IgM类抗体与抗原结合形成免疫复合物激活补体系统,从而发挥补体介导的杀菌、溶菌作用。清除细菌、病毒等病原体。这主要在抗细菌和抗寄生虫感染中起作用。 5、介导细胞毒性
新冠肺炎中的NK细胞功能障碍(dysfunction)及策略
。例如,Demaria等人在外周血和支气管肺泡灌洗液中检测到较高水平的NK-19相关NK细胞中的NKG2A、PD-1和CD39。阻断NKG2A与其配体与抗NKG2A单克隆抗体的相互作用增强了COVID-19患者NK细胞的细胞毒性活性。另一方面,Krämer等人在一些COVID-19患者中检测到NK细胞上的TIGIT表达增加。TIGIT NK细胞比COVID-19患者的TIGIT NK细胞产生更多的IFN-γ。这些研究表明,COVID-19患者中NK细胞的活性受到抑制性检查点受体的抑制。 2. 使用离体扩增NK
