Abstract
Characterizing resident immune cells in human skin using single-cell assays provides insight into their role in infections, inflammation, and cancer. We describe an optimized protocol to rapidly isolate viable cells from 6-mm skin punch-biopsies. We provide an example in which we coupled single-cell RNA sequencing (scRNA-seq) with single-cell T-cell receptor sequencing (scTCR-seq) of skin and blood cells to study transcriptional profiles and clonotypes of skin resident and peripheral circulating, memory, and effector T cells. This is an improved protocol based on Saluzzo et al. (2021). For complete details on the use and execution of this protocol, please refer to Saluzzo et al. (2021).
