Isolating peripheral blood mononuclear cells from HIV-infected patients for single-cell RNA sequencing and

Single-cell RNA sequencing (scRNA-seq) of peripheral blood mononuclear cells (PBMCs) allows the dissection of transcriptional changes in immune cells with HIV infection. Here, we isolate PBMCs from HIV-infected individuals. After counting the cell number and verifying cell viability, we perform scRNA-seq for PBMCs on the 103 Genomics protocol and the Illumina NovaSeq 6000 sequencing platform. Furthermore, we analyze the function and cellular trajectories of B cell subsets and B cell receptor (BCR) repertoire after filtering raw sequences data and normalizing gene expression.For complete details on the use and execution of this protocol, please refer to Jia et al. (2022).
