Project description:Regulatory NK cells: IL-18-elicited NK cells with immunosuppressive functions

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:Introgressed variants from other species can be an important source of genetic variation because they may arise rapidly, can include multiple mutations on a single haplotype, and have often been pretested by selection in the species of origin. Although introgressed alleles are generally deleterious, several studies have reported introgression as the source of adaptive alleles-including the rodenticide-resistant variant of Vkorc1 that introgressed from Mus spretus into European populations of Mus musculus domesticus. Here, we conducted bidirectional genome scans to characterize introgressed regions into one wild population of M. spretus from Spain and three wild populations of M. m. domesticus from France, Germany, and Iran. Despite the fact that these species show considerable intrinsic postzygotic reproductive isolation, introgression was observed in all individuals, including in the M. musculus reference genome (GRCm38). Mus spretus individuals had a greater proportion of introgression compared with M. m. domesticus, and within M. m. domesticus, the proportion of introgression decreased with geographic distance from the area of sympatry. Introgression was observed on all autosomes for both species, but not on the X-chromosome in M. m. domesticus, consistent with known X-linked hybrid sterility and inviability genes that have been mapped to the M. spretus X-chromosome. Tract lengths were generally short with a few outliers of up to 2.7 Mb. Interestingly, the longest introgressed tracts were in olfactory receptor regions, and introgressed tracts were significantly enriched for olfactory receptor genes in both species, suggesting that introgression may be a source of functional novelty even between species with high barriers to gene flow.

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
