Project description:We analyzed gene expression profiles of IL-18 generated murine NK cells in comparison to unstimulated, freshly isolated splenic NK cells. We identified a set of 1414 Affymetrix probe sets showing significant misregulation (Welch's T-test, p<0.05; Benjamini-Hochberg FDR corrected). IL-18 generated as well as unstimulated NK cells were isolated in three independent preparations and used for RNA extraction and hybridization on Affymetrix microarrays.

Project description:NK cells are an emerging cancer cellular therapy and potent mediators of anti-tumor immunity. Cytokine-induced memory-like (ML) NK cellular therapy is safe and induces remissions in acute myeloid leukemia (AML) patients. However, the dynamic molecular changes that occur after memory-like differentiation in vitro are unclear. Here, control or ML NK cells purified from normal donor PBMC were generated in vitro. Briefly, RosetteSep-purified NK cells were incubated in IL-12, IL-15, and IL-18, or low-dose IL-15 as a control for 16-18 hours. Control or cytokine-activated NK cells were washed three times and cultured for 6 days in low-dose IL-15, which is required for NK cell survival. After 6 days, RNA was isolated from control and memory-like (ML) NK cells (IL12/15/18 activation) and RNA-sequencing performed. Because the transcription factor GATA-3 was increased specifically in ML NK cells, we hypothesized ML NK cells would exhibit a GATA-3 gene signature compared to control NK cells. Indeed, using GSEA, a significant gene signature was associated with ML NK cell differentiation. These data support the role for GATA-3 in regulating the ML NK cell molecular program.

Project description:Cancer-induced tolerance mostly involves myeloid suppressor cells, regulatory T cells and immunosuppressive cytokines, which all subvert adaptive immune responses against tumor cells. Here, we show that a subset of innate effectors, c-kit expressing NK cells (Kit+ NK), can participate in tumor-induced tolerance by compromising the NK cell arm of tumor immunosurveillance. IL-18 produced by tumor cells can convert Kit- into Kit+ NK cells that overexpress B7-H1/PD-L1 molecules. Upon tumor inoculation, Kit+ NK cells rapidly develop in lymphoid organs in a IL-18R/MyD88 dependent manner and directly kill Kit- NK cells in a B7-H1/PD-1-dependent manner, thereby promoting the progression of NK-controlled cancers. Our data suggest that, in a tumoral context, IL-18 subverts antitumor NK cell functions. Systemic neutralization of IL-18 by IL-18-binding protein may improve the NK-mediated immunosurveillance.

Project description:In this study we have compared the proteomic profile of extracellular vesicles (EVs) prepared from primary, human NK cells or the human NK cell lines NK-92 and KHYG-1 cultured for 48hrs in serum-free conditions. EVs were harvested from cells either under resting conditions (culture in IL-15) or upon activation (combination of IL-12, IL-15, and IL-18). In addition, primary NK cells were activated in the presence of anti-CD16-coated beads, and EVs harvested after 48hrs. The aim was to compare their ability to target and kill a variety of tumor cell line-derived spheroids
