Interleukin-4 Antagonizes Inflammation and Aging Caused Hematopoiesis Dysregulation

ABSTRACT: IL-4, not only drives Th2 cell differentiation and reprogram macrophages toward an anti-inflammatory state but also plays crucial roles in aging and immunotherapy. However, the role of IL-4-STAT6 signaling in hematopoietic stem and progenitor cells (HSPCs) are less studied. So we sequenced mRNA from IL-4-treated or STAT6-KO HSPCs, LT-HSCs and MPPs, to address the roles of IL-4-STAT6 signaling in hematopoiesis.

The enzyme paraoxonase-2 modulates hematopoiesis through redox signaling

Project description:Long-term hematopoietic stem cells (LT-HSCs) reside in bone marrow (BM) niches with low levels of oxygen and reactive oxygen species (ROS). ROS enhancement results in differentiation of LT-HSCs. Redox disturbances are involved in BM failure and leukemia. Paraoxonase-2 (PON2) has been shown to be important for ROS control. However, the role of PON2 in the hematopoietic system has not been addressed. Analysis of young mice with inactivated Pon2 gene (Pon2-/- mice; 3 months) revealed changes in quantity of hematopoietic stem and progenitor cells (HSPCs), which indicate changes in cell differentiation. Experiments with aged PON2-/- mice (>9 months) showed alterations of the HSPC compartment indicating changed self-renewal ability of HSCs and myeloid skewing. Reciprocal BM transplantation reveals cell intrinsic as well as extrinsic phenotypes. We observed markedly enhanced superoxide levels in BM as well as slightly enhanced total ROS level in short term (ST)-HSCs and multipotent progenitor cells (MPPs) of young mice. In aged mice, total ROS level was slightly increased in all 3 fractions of the Lin-, Sca1+, ckit+ (LSK) population. No changes in the amount of DNA double-strand breaks in LSK cells and decreased apoptosis rates in LT-HSCs of young as well as LT- and ST-HSCs of aged PON2-/- mice were seen, indicating a strong compensation mechanism. Changes of gene expression in PON2-/- LT-HSCs identified by RNA sequencing strengthened our conclusions. Additionally, competitive and serial bone marrow transplantation experiments exposed advantages of PON2-/- BMCs in multi-lineage reconstitution. Collectively, these analyses propose PON2 as crucial redox control enzyme in HSCs.

Small Nucleolar RNAs in the Dlk1-Gtl2 Imprinting Locus Maintains LT-HSC Self-renewal by Regulation of rRNA Modification and Translation [ncRNA-Seq]

Project description:Small nucleolar RNA (snoRNA) are non-coding RNAs, which participate in the chemical modification of ribosomal RNAs (rRNAs) and small nuclear RNAs. However, the roles of snoRNA in homeostasis of hematopoietic stem cells(HSCs) have not been studied. We isolated four hematopoietic stem and progenitor cells (HSPCs) (LT-HSCs, IT-HSCs, ST-HSCs, and MPPs) from the bone marrow (BM) of C57BL/6 mice and performed small RNA-seq. We found SnoRNAs belonging to SNORD113-114 cluster were specifically enriched in LT-HSCs, and their expression decreased dramatically with HSC differentiation. Here, we used a modified small RNA-seq method to examine snoRNA profiles of hematopoietic progenitor and mature cells in WT mice.

Identification of novel STAT6-regulated proteins in mouse B cells by comparative transcriptome and proteome analysis

Project description:IL-4/STAT6-regulated transcriptome and proteome were compared in primary B cells isolated from wild-type and STAT6-deficient mice. B cells were purified from the spleen and stimulated in vitro with anti-CD40 and LPS or anti-IgM-F(ab)2 in the presence or absence of IL-4. Transcriptome analysis was performed with oligonucleotide microarrays. Global relative quantification of proteins was achieved by gel-enhanced label-free liquid chromatography/mass spectrometry (LC/MS). Hierarchical clustering and principal component analysis revealed that IL-4-induced changes of the transcriptome were almost completely dependent on STAT6. In contrast, the quantitative proteome analysis revealed that the expression of many IL-4-regulated proteins changes even in the absence of STAT6. The top 75 proteins with changes in abundance levels induced by IL-4 in a STAT6-dependent manner were also found to be regulated at the transcriptional level. Most of these proteins were not previously known to be regulated by STAT6 in B cells. We confirmed the MS-based quantitative proteome data by flow cytometric and Western blot analysis of selected proteins. This study provides a framework for further functional characterization of STAT6-regulated proteins in B cells that might be involved in germinal center formation and class switch recombination.
