Production of cytokines by CD4+CAR+ T-cells in spleens

ABSTRACT: The aim of the study was to compare and contrast cytokine production by CD4+ chimeric antigen receptor + T-cells and putative myeloid derived suppressor cell populations (CD11b+Gr-1 hi and lo) in the spleens of Balb/c mice which had received a transfer of CD19 specific second-generation CAR T-cells 56 days previously following cyclophosphamide pre-conditioning.

Production of cytokines by CD4+CAR+ T-cells in spleens

Project description:The aim of the study was to compare and contrast cytokine production by CD4+ chimeric antigen receptor + T-cells and putative myeloid derived suppressor cell populations (CD11b+Gr-1 hi and lo) in the spleens of Balb/c mice which had received a transfer of CD19 specific second-generation CAR T-cells 56 days previously following cyclophosphamide pre-conditioning. Splenocytes from four individual mice were pooled, incubated with antibodies to CD4, CD34 (CAR), CD11b, Gr-1 and sorted using flow cytometric cell sorting for CD4+CD34+, Gr-1 and the negative cell fraction. Total RNA was isolated and samples loaded in duplicate in the array. Data was normalized to global expression levels.

Notch2 receptor signaling controls functional differentiation of dendritic cells in the spleen and intestine

Project description:Dendritic cells (DCs) in tissues and lymphoid organs comprise distinct functional subsets that differentiate in situ from circulating progenitors. Tissue-specific signals that regulate DC subset differentiation are poorly understood. We report that DC-specific deletion of the Notch2 receptor caused a reduction of DC populations in the spleen. Within the splenic CD11b+ DCs, Notch signaling blockade ablated a distinct population marked by high expression of adhesion molecule Esam. The Notch-dependent Esamhi DC subset also required lymphotoxin beta receptor signaling, proliferated in situ and facilitated efficient CD4+ T cell priming. The Notch-independent Esamlo DCs expressed monocyte-related genes and showed superior cytokine responses. In addition, Notch2 deletion led to the loss of CD11b+ CD103+ DCs in the intestinal lamina propria and to the corresponding decrease of IL-17-producing CD4+ T cells in the intestine. Thus,Notch2 is a common differentiation signal for T cell-priming CD11b+ DC subsets in the spleen and intestine. We compared genome-wide expression profiles of wild-type Esam(hi) and Esam(lo) splenic CD11b+ DC populations, along with CD11b+ DCs from DC-RBPJΔ mice. Spleens from 2-3 Cx3cr1-GFP+ RBPJflox/flox CD11c-Cre+ mice or Cx3cr1-GFP+ RBPJflox/flox Cre-negative littermate controls were isolated, pooled and depleted of lymphoid and erythroid cells by negative selection on MACS columns. Live cells were stained for surface expression of CD11c, CD11b and Esam. CD11c(hi) CD11b+ DCs from control mice could be separated into Esam(lo) GFP(hi) versus Esam(hi) GFP(lo) subsets. CD11c(hi) CD11b+ DCs from RBPJ-targeted mice spleens were uniformly Esam(lo) GFP(hi). The two subsets from control mice and single Esam(lo) GFP(hi) subset from RBPJ-targeted mice were sorted using FACSAria II flow sorter and analyzed using GeneChip Mouse Gene 1.0 ST Array (Affymetrix).

Transdifferentiation of B lymphocyte line ER1 into ter cells in vitro

Project description:CD19 + ER1 (B lymphocyte line) cells differentiated into CD45 + Ter119 + ter cells in vitro, we selected CD19 + ER1 cells (CD19+CD45+TER119-CD11b+), intermediate ER1 cells (CD19-CD45+TER119-CD11b+) and Ter119 + CD45 + CD19 - ER1 cells (CD19-CD45+TER119+CD11b+) for transcriptome analysis. We then performed gene expression profiling analysis using data obtained from RNA-seq of those 3 cell lines.

Transcriptional profile of B cells isolated from neonatal and adult hearts

Project description:We have identified four distinct B cell subgroups within the naïve murine heart, whose relative expression changed markedly throughout development, including CD19+CD11b+CD5+, CD19+CD11b+CD5-, CD19+CD11b-CD21+CD23+, and CD19+CD11b-CD21-CD23- B cells. In order to gain further insight into the identity of the various myocardial B cells subsets, we performed single cell RNA sequencing (scRNAseq) of neonatal (2 weeks) and adult (8 weeks) myocardial B cells. We combined 10X single cell gene expression analysis with immunostaining using TotalSeq antibodies against CD11b, CD23, and CD21.

Transfer of antigen target into CAR T cells via trogocytosis

Project description:To characterize transfer of molecules from target cells into CAR T cells via trogocytosis we cultured NALM-6 leukemia cell line expressing a CD19-mCherry fusion protein with CAR T cells. NALM6-CD19-mCherry were loaded with heavy amino acid and cocultured with CAR T cells for 1 hour. CAR T cells were next sorted into two fractions, mCherry-positive (TrogPos), and -negative (TrogNeg). Proteomics analysis revealed the presence of targeted antigen (CD19) in the TrogPos only.

Expression data from Trp53- or Atm-deficient Eµ-TCL1 murine CLL cells

Project description:To analyze expression differences between Trp53 pro-and deficient as well as Atm pro- and deficient murine CLL tumors developing in the Eµ-TCL1 mouse model, we analyzed splenocytes isolated from heavily infiltrated spleens of sick mice. To investigate differences in the response to cyclophosphamide, we also analyzed splenocytes from leukemic animals that were isolated twelve hours after intraperitoneal injection of cyclophosphamide.

IRF8-regulated genes in primary CD11 b cells

Project description:Transcriptional profiling of IRF8-regulated genes in mouse CD11b-positive primary cells. CD11b-positive cells were isolated from spleens of age-matched wt and IRF8 KO mice, the compared for their gene expression profiles. The objective is to identify genes that are regulated by IRF8 in CD11b-positive primary cells.
