Project description:[Background] TNFa-induced adipose-related protein (TIARP) is a six-transmembrane protein that is expressed on macrophages, neutrophils and synoviocytes. We have recently reported that TIARP deficient mice (TIARP-/-) spontaneously developed arthritis, and had the high susceptibility to collagen-induced arthritis (CIA) with enhanced interleukin (IL)-6 production. However, the effect of TIARP to neutrophils and fibroblast-like syonoviocytes (FLS) has not been clearly elucidated. [Methods] We analyzed the roles of TIARP in K/BxN serum transfer model using TIARP-/- mice. We characterized the differences of neutrophils between WT and TIARP-/- mice by DNA microarray. Transmigration assays of TIARP-/- neutrophils were performed in vitro and in vivo. FLS were cultured with TNF? and the production of CXCL2 (a specific ligand of CXCR1 and CXCR2) and IL-6 were measured by ELISA. Moreover, TIARP-/- mice transferred with K/BxN serum were treated with anti-IL-6R antibodies. [Results] Arthritis in TIARP-/- mice transferred with K/BxN serum was significantly exacerbated. We identified overexpression of CXCR1 and CXCR2 in TIARP-/- neutrophils by DNA microarray. Neutrophils from TIARP-/- mice showed strong migration activity. The enhancement of chomotactic activity of TIARP-/- neutrophil was greatly facilitated by CXCL2 in vitro and in vivo. In addition, TIARP-/-FLS has enhanced the production of CXCL2 and IL-6 and the cell proliferation in the presence of TNFa, and the blockade of IL-6R significantly attenuated arthritis in vivo. [Conclusion] Our findings indicate that TIARP might down-regulate the production of CXCL2 and IL-6 in FLS, and the expression of chemokine receptors (CXCR1 and CXCR2) in neutrophils, resulting in the protective ability of neutrophils migration into arthritic joints. Mice were treated with thiogycollate medium intraperitoneally. After 3 days, peritoneal macrophages were isolated from three WT or TIARP-deficient mice, and these cells were stimulated by TNF? for 24 hours. Ly6G+ Neutrophils were isolated from splenocytes by MACS.

Project description:Mammals heal faster with imperfect fibrotic scars, while amphibians regenerate slower with scarless wound healing. These observations support the prevailing paradigm that speed of wound closure is inversely related to repair quality. Here we find evidence that this is a false trade-off. In multiple injury models, mice lacking CXCR2 (CXCR2-KO) globally improved both speed and quality of skin wound healing, including hair regeneration. We found CXCR2 primarily expressed in neutrophils, and injury induced neutrophils to secrete neutrophil extracellular traps (NETs). Mice engineered to be specifically deficient in myeloid CXCR2 or NET production partially recreated the phenotype with improved early speed of wound closure. Thus, CXCR2+ neutrophils regulate the speed of wound closure.

Project description:By performing transcriptome-wide RNA sequencing (RNA-seq) analysis on the peritoneal neutrophils from Alkbh5-deficient mice (Alkbh5-/-) and Wild-type littermates (Alkbh5+/+) at 12h or 36h after mild cecal ligation and puncture (CLP), respectively, we want to identify potential targets of ALKBH5 and characterize the transcriptional landscape in neutrophils during antibacterial innate defense. Gene Ontology biological processes enrichment analysis of the significantly differentially expressed genes (DEGs) showed that neutrophil migration made up the most significantly enriched biological processes with annotations of neutrophil association upon loss of ALKBH5 in neutrophils, at both 12h and 36h after CLP. Many significantly DEGs also encompassed transcriptional signatures related to neutrophils, specifically to neutrophil influx into the infection site, including chemotaxis, response to chemokine, extravasation, ERK1 and ERK2 cascade, homeostasis of neutrophils. ALKBH5 deletion led to significantly decreased transcript expression of neutrophil migration-promoting Cxcr2 and Nlrp12; while increased transcript expression of neutrophil migration-suppressive Ptger4, Tnc, and Wnk1. These results demonstrated that ALKBH5 imprints migration-promoting transcriptional landscape in neutrophils to enable their migration into the site of infection for antibacterial innate defense.

Project description:Atglflox/flox (B6N.129S-Pnpla2tm1Eek/J), S100A8-cre+/- (B6.Cg-Tg(S100A8-cre,-EGFP)1Ilw/J) mice were obtained from The Jackson Laboratory. Atglflox/flox mice were bred to S100A8-cre+/- mice to generate Atglflox/WTS100A8-cre+/- mice, which were backcrossed onto Atglflox/flox mice to generate Atglflox/floxS100A8-cre+/- mice (Atgl neutrophils-specific knock out, Atgl-cKO). Age-matched littermate Atglflox/flox mice were used as wild-type (WT) controls. To compare of the gene expression of the lung-infiltrating neutrophils isolated from Atgl-cKO mice and their WT littermates, AT3-g-csf cells were injected into the fourth mammary fat pads of female WT and Atgl-cKO mice (10-week-old, n = 4/group). The AT3-g-csf cell line is based on a murine breast cancer cell line (AT3) derived from MMTV-PyMT tumors in the C57BL/6 background, and further constructed to overexpress granulocyte-colony stimulating factor (G-CSF) for induction of the host inflammatory condition. At day 10 (pre-metastatic stage), the mice were euthanized and then Ly6G+ neutrophils were isolated from lung by using anti-Ly6G MicroBead Kit (Miltenyi Biotec) following manufacturer’s instructions. The isolated neutrophils were analyzed by flow cytometry and the cells with a > 95% purity were used for the next procedure. Total RNA was isolated from neutrophils using the miRNeasy Mini kit (Qiagen) and the transcriptional profiles of neutrophils were analyzed by RNA sequencing.
