pmel-1 T 细胞是什么? - 知乎
这个小鼠是携带pmel-1基因重排的T细胞受体的转基因小鼠。 pmel-1这个基因特异于人SILV(gp100)的小鼠同源物(pmel-17),是一种由大多数恶性黑素瘤细胞(包括B16黑素瘤)以及正常黑色素细胞表达的参与色素合成的酶。

This transgenic strain carries a rearranged T cell receptor transgene specific for the mouse homologue (pmelSi or pmel-17) of human premelanosome protein (referred to as PMEL, SILV or gp100), and the T lymphocyte spec...
Adoptive T cell therapy has emerged as a promising treatment for cancer. However, it is unknown whether adoptively transferred anti-tumor T cells can form immunological memory and provide continuous protection against...
The involvement of tumour-resident memory T (TRM) cells in responses to immune checkpoint inhibitors remains unclear. Here, we show that while CD103+CD8 TRM cells are involved in response to PD-1 ...
在开始这篇文章的学习之前,我们最开始要搞清楚的一个问题就是: 什么是过继性免疫细胞疗法? 过继性免疫治疗(ACT),是指从肿瘤患者体内分离免疫活性细胞,在体外进行扩增和功能鉴定,然后向患者回输,从而达到直接杀伤肿瘤或激发机体免疫应答杀伤肿瘤细胞的目的。 随着ACT疗法的迅猛 ...
PMEL基因概述 PMEL基因,也称为premelanosome protein,位于人类染色体12q13.2位置。这个基因编码的蛋白在黑色素细胞中起着至关重要的作用,特别是在黑色素的合成和储存过程中。PMEL蛋白,也被称为Pmel17或gp100,是黑色素小体的主要成分,这些小体是存储黑色素的细胞器。
黑色素体(melanosome)是决定皮肤、毛发和眼睛颜色的关键细胞器。其生物发生和功能失衡导致多种遗传性低色素综合征、黑色素瘤及相关系统性疾病。研究人员早期就注意到其内部存在规则的片层状结构,但这些片层如何由黑色素体结构蛋白 PMEL 组装而成、在原位呈现何种三维构型,一直缺乏原子 ...
