Project description:Six-weeks old (C57Bl6, Cx3cr1gfp/+) mice were intraperitonealy infected with a low number (1.104) of L. monocytogenes (EGDe strain) in exponential growth phase (bacteria were grown in BHI at 108/ml, and diluted 10.000x in PBS immediately before injection). Group of three mice were euthanized, before infection. Peritoneal cells were recovered by peritoneal lavage. Cells from individual mice were stained with antibodies to CD11b (PECy7), Gr1 (APC), NK1.1, B220 and CD3 (PE), and F4/80 (biotin-conjugated followed by streptavidinpacific blue) for sorting. Gr1- monocytes were purified as NK1.1- CD3- B220- CD11b+ F4/80low Gr1-, gfphigh; Gr1+ monocytes were purified as NK1.1- CD3- B220- CD11b+ F4/80low Gr1+, gfpint; and polymorphonuclear cells were purified as NK1.1- CD3- B220- CD11b+ F4/80- Gr1high, gfp-. 1.103 cells from each mice, time point, and phenotype were purified by facs sorting according to their phenotype. Samples were kept at 4°C before and during the sort. Cells were directly sorted in the SuperAmp Lysis Buffer (Miltenyi Biotec, Bergisch Gladbach, Germany) using a FACS Aria cell-sorter (BD biosciences).

Project description:NOD mice are an inbred strain that display enhanced MZ B cell differentiation from an early age. Interestingly, several lines of evidence implicate MZ B cells in this strain as important contributors to the T cell mediated beta cell destruction associated with the development of type 1 diabetes (T1D). In order to develop a better understanding of the underlying causes for augmented MZ B cell production in NOD mice, we obtained the transcriptional profiles of FO and MZ subsets and TR precursors from NOD mice and compared them to those of the B6 strain. Red cell depleted splenocyte suspensions from from eight pooled NOD or B6 mice were stained with biotinylated anti-CD3ε (145-2C11) and CD11b (M1/70, BD Biosciences) antibodies followed by anti-biotin Microbeads (Miltenyi Biotec, Bergisch Gladbach, Germany). Separation of unlabeled B cells from samples was achieved to a >93% purity (as determined by flow cytometry) by negative depletion with an autoMACS cell sorter (Miltenyi Biotec). These cells were then stained with a cocktail of: non-stimulatory Affinipure goat anti-mouse-IgM-FITC Fab fragments from Jackson Immunoresearch; anti-CD21/35-PE (7G6), anti-CD24-biotin (30-F1; with streptavidin-PerCP secondary), B220-APC-Cy7 (RA36B2) from BD Biosciences; anti-CD93-APC (AA4.1), anti-CD23-PE-Cy7 (B3B4) from eBiosciences. T1, T2FO, T3, FO, T2MZ and MZ subsets were then separated with a FACSAria Cell Sorter (BD Biosciences). This process was repeated in an independent experiment in order to generate a duplicate sample of each B cell subset from NOD and B6 mice. Labelled cRNA from B cell samples were hybridized to Mouse Genome 430 2.0 Arrays.

Project description:Identification of genes differentially expressed between human CD14+CD16- and CD16+ monocyte-derived macrophages generated in the presence of either GM-CSF (termed GM14 and GM16, respectively) or M-CSF (termed M14 and M16, respectively) Human peripheral CD14+CD16- and CD16+ blood monocytes from three independent healthy donors (D1, D2 and D3) were isolated by positive selection from peripheral blood mononuclear cells (PBMC) using magnetic separation systems (MACS, Miltenyi Biotec). Briefly, PBMC were first incubated with MACS anti-CD56 antibody conjugated to paramagnetic microbeads in order to eliminate the NK (CD16+) cell fraction. NK-depleted PBMC were further incubated with MACS anti-CD16 antibody to isolate CD16+ monocytes. CD56-CD16- PBMC were finally incubated with MACS anti-CD14 antibody to obtain the CD14+CD16- monocyte fraction. Monocytes were cultured for 7 days in medium containing either GM-CSF or M-CSF. Total RNA from each condition was extracted using the RNeasy kit (Qiagen) and hybridized to an Agilent Human Whole Genome (4x44) Oligo Microarray. All experimental procedures were performed following manufacturer instructions.

Project description:To identify the miRNA expressing profiles of TIE2 expressing Monocytes (TEMs), we have employed the Agilent Human miRNA 8×60K (Design ID:046064) microarray. Human peripheral blood mononuclear cells (PBMCs) in venous blood from healthy donors were isolated by Lymphoprep (Axis-Shield, Norway). Human monocytes in PBMCs, identified as cells that expressed CD14, were enriched by positive immunomagnetic selection using anti-CD14 MicroBeads (Miltenyi, Germany). TEMs (TIE2+CD14+) and TIE2-Monocytes (Tie2-CD14+) were then isolated by FACS-sorting (Aria II, BD Biosciences) using FITC-conjugated anti-CD14 (BD Biosciences, USA) and APC-conjugated anti-TIE2 (R&D System, USA) antibodies.Three TEMs samples together with their paried TIE2-Monocytes were detected.

Project description:Gene expression patterns in IL-15 or IL-15/AgN2a-4P expanded B6 NK cells treated with anti-TIM-3 antibody or IgG2a isotype control were analyzed using the nCounter Mouse PanCancer Immune Profiling Panel. Prior to RNA processing, NK cells were purified using the AutoMACS pro-separator (Miltenyi Biotec, San Jose, CA). The treatment involved a 4-hour exposure to antibodies before gene expression analysis, aiming to elucidate differential expression profiles in response to anti-TIM-3 treatment compared to the control condition.

Project description:We investigated the frequency of CX3CR1+CD8+ T cells in peripheral blood (PB) before and during immune checkpoint inhibitor (ICI) therapy, and delineated the TCR repertoire in peripheral CX3CR1+CD8+ T-cell subsets and CD8+ tumor-infiltrating lymphocytes (TILs) using preclinical models. To understand the clinical utility of CX3CR1 as a circulating T-cell biomarker, we analyzed longitudinal PB samples from non-small cell lung cancer (NSCLC) patients undergoing anti-PD-1 therapy, and evaluated predictive and prognostic value of changes in the frequency of PB CX3CR1+ CD8+ T cells Methods: Female C57BL/6 mice were inoculated subcutaneously with 5 x 10^5 MC38 tumor cells per mouse on the right flank on day 0. When tumor volume reached approximately 50 mm^3, 200 µg of anti-PD-L1 Ab (clone 10F.9G2, BioXcell) and 100 µg of anti-CTLA-4 Ab (clone 9H10, BioXcell) were administered intraperitoneally every 3 days and every other day, respectively. MC38 tumor-bearing mice were treated for 14 days, and spleens and tumors were harvested. [Tumor cells] Tumors were cut into small pieces of 2-4 mm. Single-cell suspensions were obtained by mechanical dispersion consisting of two 30-min incubations at 37°C, 5% CO2 in 5 ml RPMI 1640 (Gibco) and tumor dissociation kit (Miltenyi Biotec) in C Tubes (Miltenyi Biotec) interspersed with three mechanical dispersions on a GentleMACS dissociator (Miltenyi Biotec). The tumor cell suspensions were then filtered through a cell strainer (70 μm; BD Biosciences). An EasySep Mouse CD8a Positive Selection Kit II (STEMCELL Technologies) was used to isolate murine CD8+ tumor-infiltrating lymphocytes (TILs) for TCR sequencing. [Splenocytes] Spleens were homogenized by forcing the tissue through a cell strainer (70 μm; BD Biosciences). Red blood cells in blood and spleen were lysed using ACK Lysis Buffer (Gibco). For TCR sequencing of murine splenic CD8+ T cells, single cell suspensions from freshly isolated splenocytes were stained. CD45+ CD3+ CD8+ T cells were gated, and CD27lo CX3CR1-, CD27hi CX3CR1-, and CX3CR1+ CD8+ T cells were sorted using BD FACSAria II Cell Sorter. DNA from flow-isolated murine splenic CD8+ T cells and CD8+ TILs, and PB CD8+ T cells was extracted using QIAamp DNA Micro Kit (QIAGEN). DNA was quantified using Qubit dsDNA BR Assay (Invitrogen). Amplification and sequencing of TCRβ CDR3 regions was performed using ImmunoSEQ immune profiling system at the survey level (Adaptive Biotechnologies). Sequencing was performed on an Illumina NextSeq system using 150 cycle mid-output kit (Illumina Inc.). Processed data were uploaded to the ImmunoSEQ Platform (Adaptive Biotechnologies) for bioinformatics analysis. Processed data were downloaded and frequencies/counts for TCR clonotypes and diversity were examined by nucleotide sequences after non-productive reads were filtered out. Results: Clonally expanded TCR repertoires of CD8+ TILs are enriched in the peripheral CX3CR1+ subset during ICI therapy. ICI therapy induces high degree of TCR sequence similarity and clonality between CD8+ TILs and the peripheral CX3CR1+ CD8+ T cells.
