Single-cell multiomics reveals a shared regulatory program in progenitor CD8 T cells and follicular helper CD4 T cell during viral infection

ABSTRACT: We generated a new single-cell multiomic (scRNA-seq + scATAC-seq) dataset of CD4 and CD8 T cells responding to acute and chronic viral infection. To explore potential regulatory functions that might be shared by different populations of T cells, we generated a new single-cell multiomic (scRNA-seq + scATAC-seq) data for CD4 and CD8 T cells responding to acute and chronic viral infection. By integrating this new dataset with a compendium of 285 published bulk ATAC-seq datasets, we were able to identify all major T cell states, including naive, memory, effector, follicular helper (Tfh), regulatory, exhausted and progenitor populations, across both infection contexts. Archetypal analysis revealed regulatory programs that were driven by distinct transcription factors acting across multiple T cell subsets. Our work provides a broadly applicable framework and a valuable resource for dissecting transcriptional control mechanisms in adaptive immune responses.

scATAC-seq of mouse Plasmodium-specific CD4+ T cells

Project description:Plasmodium-specific CD4+ T cells from mice infected with Plasmodium chabaudi chabaudi AS parasites were recovered at Days 0, 4, 7, and 32 to undergo processing and to generate scATAC-seq dataset. At Day 7, CXCR5+ and CXCR6+ cells were recovered separately. At Day 32, mice were administered with either saline or artesunate (intermittent artesunate therapy - IAT). scATAC-seq dataset was analysed to investigate epigenomic landscapes of CD4+ T cells from effector to memory states.

An atlas of gene regulatory networks for T memory cells in youth and old age [scATAC-seq]

Project description:We previously identified a population of IL-10-producing, T follicular helper-like cells ("Tfh10"), linked to suppressed vaccine responses in aged mice. Here, we applied scRNA-seq and scATAC-seq to characterize Tfh10 – and the full CD4+ memory T cell (CD4+TM) compartment – in young and old mice. Unprecedented scRNA-seq coverage of the CD4+TM compartment and parallel chromatin accessibility measurements (scATAC-seq) enabled identification of 13 CD4+TM populations, which we validated as a reference through comprehensive cross-comparison to aging cell atlases and scRNA-seq studies reporting Tfh10 in other contexts. In addition, we compared sc-resolved populations to flow-sorted CD4+TM populations (Treg, Tfh10 and "nonTfh, non-Treg IL-10-") subjected to bulk RNA-seq and bulk ATAC-seq. Beyond robust characterization of age- and cell-type-dependent transcriptional landscapes, we used integrative computational modeling to predict the underlying regulatory mechanisms: We inferred gene regulatory networks (GRNs) that describe transcription-factor control of gene expression in each T-cell population and how these circuits change with age. Furthermore, we integrated our data with prior, pan-cell scRNA-seq studies to identify intercellular-signaling networks driving age-dependent changes in CD4+TM. Our atlas of finely resolved CD4+TM subsets, GRNs and cell-cell communication networks is a critical resource for analysis of biologic processes operative in memory T cells in youth and old age. The resource presents new opportunities to manipulate regulatory circuits in CD4+TM, which, long-term, could improve immune responses in the elderly.

The epigenomic landscape of cognitive stimulation in the context of aging in mouse dorsal hippocampus - SWATH

Project description:Aging is a universal biological phenomenon linked to many diseases, such as cancer or neurodegeneration. However, the molecular mechanisms underlying aging, or how lifestyle interventions such as cognitive stimulation can ameliorate this process, are yet to be clarified. Here, we performed a multi-omic profiling, including RNA-seq, ATAC-seq, ChIP-seq, EM-seq, SWATH-MS and single cell Multiome scRNA and scATAC-seq, in the dorsal hippocampus of young and old mouse subjects which were subject to cognitive stimulation using the paradigm of environmental enrichment. In this study we were able to describe the epigenomic landscape of aging and cognitive stimulation.
