Memory like NK cells display stem cell like properties after Zika virus infection

Project description:In this study, we show that CD27+ memory like NK cells generated following Zika virus infection exhibited stem-like features viz., self-renewal pathway, differentiation into effector cells and longer telomeres, and greater therapeutic potential than CD27- and naive CD27+ NK cells when adoptively transferred to Zika virus infected mice. In addition, epigenetic landscape of CD27+ memory like NK is markedly different compared to CD27- NK cells.

Memory like NK cells display stem cell like properties after Zika virus Infection

Project description:Here we show that Zika virus infection induces memory like NK cells that express CD27. This subset shared transcriptional changes with memory CD8 T cells, stem cells and stem like T cells. These NK cells with memory and stemness features which we term NK memory stem cells (SCMNK) demonstrated greater antiviral potential. Transcriptional data of SCMNK and non-memory NK cells is presented.

Memory like NK cells display stem cell like properties after Zika virus infection.

Project description:NK cells have been shown to display adaptive traits such as memory formation akin to T and B lymphocytes. Here we show that Zika virus infection induces memory like NK cells that express CD27. Strikingly, these cells exhibit stem-like features that include expansion capacity, self-renewal pathway, differentiation into effector cells, longer telomeres and gene signature associated with hematopoietic stem cell (HSC) progenitors. This subset shared transcriptional and epigenetic changes with memory CD8 T cells, stem cells and stem like T cells. These NK cells with memory and stem cell features, which we term "NK memory stem cells", demonstrated greater antiviral potential than CD27- or naïve CD27+ NK when adoptively transferred to Zika infected mice. Our results also suggest a role for the transcription factor TCF-1 in memory and stemness features of this NK subset. This study defines a unique TCF1hi CD27+ NK subset with memory capacity and stem cell features that play a role in antiviral immunity.

CITE-seq of in vitro control and memory-like human NK cells

Project description:Peripheral blood NK cells were cultured into either control or cytokine-induced memory-like NK cells as described in PMID: 32614951. After differentiation, cells were labeled with hashtag antibodies and cite-seq antibodies and control and memory-like NK cells were combined and loaded onto the 10x Genomics Chromium Instrument a the McDonnell Genome Institute at Washington University School of Medicine. The following samples were analyzed to develop a classification tool for unbiased identification of memory-like NK cells in a bulk single-cell RNA-seq population.

Transcriptome analysis of TIML- and CIML-NK cells

Project description:NK cells may acquire under certain conditions features of adaptive immune cells. As the functional role of memory NK cells in cancer has so far remained elusive, we reasoned whether tumor-priming itself might promote memory NK cell generation. We provide substantial evidence that independent from pro-inflammatory stimulation, tumor-induced memory-like (TIML) NK cells exhibit a heightened, tumor-restricted cytotoxicity which is dependent on a higher/faster perforin but not IFN-Î³ release. Comparative transcriptome analysis reveals that gene expression patterns differ between TIML- and Cytokine-induced memory-like (CIML)-NK cells.
