Another subset of antigen-driven CD4+ T cells, named regulatory T cells (Treg), acts by inhibiting T cell responses by the production of cytokines, such as IL10 and TGF-β and/or via cell–cell interactions (Jutel and Akdis 2011). Treg are CD4+ cells that also express the α-chain ...

可视化结果发现,Nebulosa可视化(左图)会比Seurat自带的绘图函数(右图)效果好很多;同时也表明了CD4+ cell存在相当多的dropout。再加上CD3D可视化结果(Fig3),我们很容易可以判断cluster 0,1为 CD4+ T cell。 Fig 3:CD3D UMAP可视化 数据准备多个Marker基因联合可视化 ...
cellranger标准的三文件输出可以使用Read10X函数读入为表达矩阵,其他文件格式读入我们后续专门整理: pbmc.data <- Read10X(data.dir = "./filtered_gene_bc_matrices/")#[1] 32738 2700 读入后使用CreateSeuratObject函数创建一个Seurat对象,同时过滤低质量细胞。
