B cell-intrinsic STAT6 controls the germinal center response in type 2 immunity

ABSTRACT: By investigating the germinal center (GC) formation in STAT6ko/WT bone marrow-mixed chimera we found that GC formation in type 2 immune responses is dependent on B cell intrinsic expression of IL-4/IL-13-induced genes. We therefore used microarrays to find Stat6 dependent genes that are important for germinal center formation and/or organization after infection with the nematode Nippostrongylus brasiliensis (N. brasiliensis). Bone marrow of STAT6ko (CD45.2+) and WT (CD45.1+) were mixed and injected in lethaly irradiated WT (CD45.1+) mice. After 8 weeks, 5 Bone marrow-mixed chimera were infected with N. brasiliensis and draining lymph nodes were collected at day 14 after the infection and pooled. RNA was isolated from sort-purified CD45.1+ or CD45.2+ GC B cells (B220+CD38loGL-7hi).

Infection with helminths and exposure to antigens induce a strong type 2 immune response resulting in the secretion of the cytokines IL-4 and IL-13 by CD4(+) T cells and several innate cell types. IL-4 and IL-13 promote class switch recombination to IgG1 and IgE while their role for germinal center (GC) formation is poorly understood. We found a dramatic reduction in the numbers of GC B cells when investigating different type 2 immune responses in IL-4/IL-13-deficient mice. IL-4/IL-13 from T cel ...[more]

Genome-wide expression study of the responses of murine NK cells and dendritic cell subsets to MCMV infection

Project description:Murine Cytomegalovirus (MCMV) infection leads to the activation of various immune cells, including dendritic cells (DCs) and Natural Killer (NK) cells. This activation is partly driven by innate cytokines including IFN-I, which are induced early after infection. The objective was to address the role of different innate cytokines in shaping DC subsets and NK cell responses, in particular the role of cell intrinsic responses to IFN-I. In order to decipher the specific impact of cell-intrinsic IFN-I on cell subsets, we performed a genome-wide expression analysis on CD45.1 WT and CD45.2 IFNAR-/- splenic conventional DC (cDC) subsets and NK cells isolated from C57BL/6 [CD45.1 WT / CD45.2 IFNAR-KO] mixed bone marow chimera mice. This study includes data from cDC subsets (CD8a and CD11b) and NK cells purified by flow cytometry sorting from the spleen of bone marrow chimera (BMC) mice, under steady-state or MCMV condition. Two independent replicates were made for each cell type, from two independent pools of spleens from uninfected or d1.5 MCMV-infected BMC 5-8 mice, and were hybridized on 3 separate batches of gene chips.

Single-cell RNAseq (10x Genomics) analysis of mouse splenic CD4+ T cells in WT and ∆Foxp3 mice and in WT/∆Foxp3 bone marrow chimeras

Project description:Single-cell RNAseq (10x Genomics) analysis of mouse splenic CD4+ T cells in WT and ∆Foxp3 mice and in WT/∆Foxp3 bone marrow chimeras. Mouse CD4+T cells in 21-day-old male WT and ∆Foxp3 mice were isolated from spleen by flow cytometry as DAPI–TCRβ+CD4+ cells for 10x Genomics Single Cell 3′ Reagent Kit (V2 chemistry, one sample per channel). For bone marrow chimera experiment: 7 week-old CD45.2-recipient mice were irradiated with 1000 Rad, reconstituted with 4 million CD3-depleted bone marrow cells: 50% CD45.1 x Foxp3-IRES-GFP (WT, 21d-old male) and 50% Foxp3DeltaEGFPiCre/RFP x ROSA-YFP x CD45.1/2 (scurfy, 21d-old male). 10 weeks later, spleen were harvested and tagged using a different Hashtags fo each mouse. ∆Foxp3 CD4+ T cells were sorted as DAPI–TCRb+CD4+CD45.1+CD45.2+. WT CD4+ T cells were sorted as DAPI–TCRb+CD4+CD45.1+CD45.2–. Control WT DAPI–TCRb+CD4+GFP+ Treg cells and GFP- Tconvs cells were also tagged and sorted. Samples with different hastags were pooled before single cell encapsulation using 10x Genomics Single Cell 3′ Reagent Kit (V3 chemistry).

Genome-wide expression study of the early/innate responses of murine B and T cells to MCMV infection

Project description:Murine Cytomegalovirus (MCMV) infection leads to early activation of various immune cells, including B and T lymphocytes, before the actual initiation of antigen-specific adaptive immunity. This activation is partly driven by innate cytokines, including type I interferon (IFN), which are induced early after infection. The objective of this study was to address the role of type I IFN in shaping early/innate B and T cell responses to a primary acute viral infection. In order to decipher the specific impact of IFN-I on cell subsets, we performed a genome-wide expression analysis on WT splenic B and CD8 T lymphocytes isolated from C57BL/6 [CD45.1 WT / CD45.2 IFNAR-KO] mixed bone marrow chimera mice. This study complements series GSE39555, which focused on early responses of NK cells and of the two subsets of conventional dendritic cells. This study includes data from B and CD8 T lymphocytes purified by flow cytometry sorting from the spleen of bone marrow chimera (BMC) mice, under steady-state or MCMV conditions. Two independent replicates were made for each cell type, from two independent pools of spleens from uninfected or d1.5 MCMV-infected BMC 5-8 mice, and were hybridized on 3 separate batches of GeneChips.

Capacity of yolk sac macrophages, fetal liver and adult monocytes to colonize an empty niche and develop into functional tissue resident macrophages

Project description:Tissue-resident macrophages can derive from yolk sac macrophages, fetal liver monocytes or adult bone marrow monocytes. Whether these precursors can give rise to transcriptionally identical alveolar macrophages is unknown. Here, we transferred traceable yolk sac macrophages, fetal liver monocytes, adult bone marrow monocytes or adult alveolar macrophages as a control, into the empty alveolar macrophage niche of neonatal Csf2rb-/- mice. All precursors efficiently colonized the alveolar niche and generated alveolar macrophages that were transcriptionally almost identical, with only 22 genes that could be linked to their origin. Underlining the physiological relevance of our findings, all transfer-derived alveolar macrophages self-maintained within the lungs for up to 1 year and durably prevented alveolar proteinosis. Thus, precursor origin does not affect the development of functional self-maintaining tissue-resident macrophages. CD45.1+CD45.2+ yolk sac macrophages, fetal liver monocytes, adult bone marrow monocytes or adult alveolar macrophages from the bronchoalveolar lavage were sorted from wild type CD45.1+CD45.2+ mice of indicated ages. From part of these samples RNA was isolated. The other part was transferred intranasally into the lungs of neonate Csf2rb-/- mice. 6 weeks post-transfer, transfer-derived CD45.1+CD45.2+ alveolar macrophages were sorted from the bronchoalveolar lavage. Wild type CD45.1+CD45.2 alveolar macrophages from the bronchoalveolar lavage of 6 week old mice were sorted as control. 36 samples (arrays) in total. RNA was isolated, amplified with Nugene pico kit, converted to cDNA and then hybridised on Affymetrix GeneChip Mouse Gene 1.0 ST Arrays.
