Project description:IL2 signals are transmitted through JAK1 and JAK3, but the transcriptomic consequences of each to the overall response is unclear. Here we analyzed the relative contribution of JAK1 and JAK3 to the NK cell IL2 response in vitro using titrated doses of isoform specific JAK inhibitors. Blockade of JAK1 and JAK3 have unequal effects on IL2-induced transcripts at pharmacologically relevant doses. Splenic NK cells were isolated by negative selection from 6wk old male C57BL/6 mice. These were cultured with IL2 (250U/ml) in the presence or absence of JAK1/3 inhibitors for 8hrs in vitro. Cells were then transferred directly into TriZol. RNA was prepared in Trizol for gene expression profiling by Affymetrix Mouse Gene 1.0 ST Arrays.

Project description:Transcriptional profiling of NKAES-derived NK cells after 7 days of culture compared to primary human NK cells and NK cells stimulated by low or high dose IL2 after 7 days of culture. Four-condition experiment, primary NK cells vs. NKAES-derived NK cells after 7 days of culture vs. NK cells stimulated by low/high dose IL2 after 7 days of culture. Biological replicates: 5 control, 5 NKAES-derived NK cells, 3 NK cells stimulated by low dose IL2, 3 NK cells stimulated by high dose IL2 independently grown and harvested. One replicate per array.

Project description:Natural Killer (NK) cells are primary effectors of innate immunity directed against transformed cells. In response, tumor cells have developed mechanisms to evade NK cell-mediated lysis but the molecular basis for target cell resistance is not well understood. In the present study, we used a lentiviral shRNA library targeting more than 1000 human genes to identify 83 genes that promote target cell resistance to human NK cells. Many of the genes identified in this genetic screen belong to common signaling pathways, however, none of these genes have previously been known to modulate susceptibility of human tumor cells to immunologic destruction. In particular, gene silencing of two members of the JAK family (JAK1 and JAK2) in a variety of tumor cell targets increased their susceptibility to NK-mediated lysis and induced increased secretion of interferon gamma (IFN-gamma by NK cells. Treatment of tumor cells with JAK inhibitors also induced increased susceptibility to NK cell activity. These findings may have important clinical implications and suggest that small molecule inhibitors of tyrosine kinases being developed as therapeutic anti-tumor agents may also have significant immunologic effects in vivo. IM9 cells were transduced with shRNA-encoding vectors and selected with Puromycin. Two vectors were specifically targeting JAK1 (JAK1-1 and JAK1-3) and one vector encoded an irrelevant control shRNA (CTRL-2). Total RNA was obtained from the parental IM9 cell line, the control-shRNA expressing IM9 cells, the JAK1-1-shRNA and JAK1-3-shRNA expressing IM9 cells in 2 separate experiments (Exp1 and Exp2).

Project description:Here we analyzed the transcriptional response to IL2 in NK cells in vitro. Splenic NK cells were isolated by negative selection from 6wk old male C57BL/6 mice. These were directly cultured with IL2 (250U/ml) for 8hrs in vitro. Cells were then transferred directly into TriZol. RNA was prepared in Trizol for gene expression profiling by Affymetrix Mouse Gene 1.0 ST Arrays. The samples in this series are re-analyzed samples from GSE84562.
