概要: Dermal fibroblasts from human, rhesus macaque, mouse and rat, stimulated with dsRNA (poly I:C), interferon and controls.
项目整体设计: The innate immune response - the expression programme that is initiated once a pathogen is sensed - is known to be variable among responding cells, as well as to rapidly evolve in the course of mammal evolution. To study the transcriptional divergence and cell-to-cell variability of this response, we stimulated dermal fibroblast cells from two primates (human and macaque) and two rodents (mouse and rat) with dsRNA - a mimic of viral RNA that elicits a rapid innate immune response. Subsequently, we profiled the response using bulk RNA-seq, scRNA-seq and ChIP-seq across the four species and across different time points.
Non-lymphoid tissues (NLTs) harbour a pool of adaptive immune cells distinct from their counterparts in lymphoid tissues, and their development and phenotype remains largely unexplored. We used scRNA-seq to survey CD4+ T regulatory (Treg) and memory T (Tmem) cells in spleen, lymph nodes, skin and colon in an unbiased way, in mouse and human.
建库方案:
This cross-tissues, cross-species comparison allows us to obtain marker genes for immune populations in specific locations with likely relevance for human studies. Additionally, a continuous phenotype of Treg migration can be modelled from the mouse data, unravelling the transcriptional stages through which these cells transition between tissues.
