The human thymus is the organ responsible for the maturation of many types of T cells, which are immune cells that protect us from infection. However, it is not well known how these cells develop with a full immune complement that contains the necessary variation to protect us from a variety of pathogens. By performing single-cell RNA sequencing on more than 250,000 cells, Park et al. examined the changes that occur in the thymus over the course of a human life. They found that development occurs in a coordinated manner among immune cells and with their developmental microenvironment. These data allowed for the creation of models of how T cells with different specific immune functions develop in humans.
粉丝小Q:小云小云,我看了你们推荐的单细胞数据分析思路,生信小白表示,有点难。看完了文章,是不是思路很简单,基本上就是构建一个风险预后模型,然后进行一些模型评估分析,超级适合新手小白作为自己首篇生信文章的模板,如果你关注的疾病还没有做内质网应激方向生信,直接拿去复现吧。

总结三者联合生信分析的优势有:1) 综合考虑细胞表达谱和空间位置信息:单细胞测序能够获得单个细胞的基因表达谱,空间转录组测序能够反映细胞在组织中的空间位置信息,联合两者可以更好地理解细胞在组织中的功能和相互作用关系。
这篇文章是发表在Nature Communications杂志上的一篇文章,题目为“Early response evaluation by single cell signaling profiling in acute myeloid leukemia”。
张泽民老师无疑是生物信息学领域的巨佬,我也多次旁听过他的课,每一次都收获很多。 这篇泛癌T cell的Science文章我反复看了很多遍,建议关注免疫细胞的同学把这篇文章打印出来,反复的看看,肯定有很大的收多。
记者3月17日从浙江大学获悉,该校医学院附属第二医院王良静教授团队、附属邵逸夫医院陈淑洁主任医师团队联合研究发现,一种肠道菌群产生的小分子代谢物吲哚丙酸,可以增强抗癌药物抗PD-1单抗对结直肠癌、乳腺癌、黑色素瘤的疗效。
浙江大学医学院教授王良静团队与主任医师陈淑洁团队合作,发现一种肠道菌群产生的小分子代谢物吲哚丙酸,可以持续调动T细胞杀伤肿瘤,增强抗PD-1单抗在结直肠癌、乳腺癌、黑色素瘤等实体肿瘤中的疗效,有望为肿瘤的精准治疗提供新策略。相关研究近日发表于《细胞》。
