Restored clearance of senescent neutrophils by tissue-resident macrophages limits organ aging

ABSTRACT: Single-cell RNA sequencing of sorted mouse liver cells from young (6-8 month) and aged (23-25 month) Cx3cr1CreER;EP2wt/wt (WT) and Cx3cr1CreER;EP2lox/lox (EP2 cKO) male mice. Liver cells were enzymatically dissociated and live CD45+, CD1d+, or CD31+ cells were FACS-sorted in a 1:1:1 ratio, then processed using the 10x Genomics Chromium X platform (Next GEM Single Cell 3' Gene Expression). This dataset supports the finding that tissue-resident macrophage (TRM)-selective EP2 (PTGER2) deletion restores efferocytic clearance of senescent neutrophils and reverses age-associated transcriptional programs in Kupffer cells, preventing multi-organ aging phenotypes.

Expression data from cumulus cells from C57Bl/6 and Ptger2 (EP2) KO mice

Project description:To understand the role of prostaglandin (PG) receptor EP2 (Ptger2) signaling in ovulation and fertilization, we investigated time-dependent expression profiles in wild-type (WT) and Ptger2-/- cumuli before and after ovulation by using microarrays. We used Affymetrix U74A ver2 microarrays to investigate gonadotropin-induced gene expression profiles in WT and EP2KO cumulus cells before and after ovulation. Immature mice were primed with pregnant mare serum gonadotropin (PMSG) as an FSH-like stimulation. The cumulus-oocyte complexes (COCs) were isolated from mice 48 h after PMSG injection (H0) and from PMSG-primed mice exposed to human chorionic gonadotropin (hCG) as an LH-like stimulation for 3, 9 or 14 h (H3, H9 or H14, respectively).

Sorting of neuronal hiippocampal signatures (ChIP-Seq H3K27ac H3k27me8)

Project description:This project aims to identify neuronal signatures in the hippocampus of Home Cage WT mice. For this, we sorted neuronal and non neuronal nuclei (NeuN+ and NeuN- ) of total hippocampus from 5-month-old WT mice. ChIP experiments were performed for 2 different histone marks (H3K27me3 and H3K27ac) in about 4-500000 sorted NeuN+ and NeuN- nuclei. H3K27ac signatures were also assessed in 12 month-old WT mice. We have INPUT DNA For each condition (NeuN+ and NeuN-).

Expression data of hepatic iNKT cells from pLck-hCD1d transgenic mice

Project description:CD1d expression by thymocytes is required to select iNKT cells. When CD1d is expressed only on thymocytes (pLck-CD1d tg mice), iNKT cells are hyperresponsive to antigen stimulation suggesting that, in physiological conditions, these cells undergo functional education mediated by additional CD1d-expressing cells. Here, we investigated the mechanisms of this functional education. We find that peripheral iNKT cells from pLck-CD1d tg mice express significantly less SHP-1, a tyrosine phosphatase negatively regulating TCR signaling, than WT cells. iNKT cells from heterozygous SHP-1-mutated motheaten mice, displaying similar SHP-1 reduction as pLck-CD1d tg iNKT cells, are antigen-hyperresponsive. Restoring normal CD1d expression in pLck-CD1d tg mice normalizes SHP-1 expression and responsiveness of iNKT cells. In WT mice, iNKT cells upregulate SHP-1 and decrease responsiveness upon emigration from thymus to periphery. This depends on contacts with CD1d-expressing DCs. iNKT cell functional education is therefore controlled by DCs via tuning SHP-1 expression level in the periphery.

In vivo response of microglia to Aβ and prostaglandin-E2 EP2 receptor signaling

Project description:Microglia, the innate immune cells of the central nervous system, perform critical inflammatory and non-inflammatory functions to maintain homeostasis and normal neural function. However in Alzheimer’s disease (AD), these beneficial functions become progressively impaired, contributing to synapse and neuron loss and cognitive impairment. The inflammatory cyclooxygenase-PGE2 pathway, including the PGE2 receptor EP2, is implicated in AD development, both in human epidemiology and in transgenic models of AD. To test the transcriptional responses of EP2-deficient microglia to Aβ in vivo, we used mice in which the EP2 receptor is conditionally deleted in microglia using the CD11b-Cre transgene and floxed alleles of the EP2 gene. By injecting these mice with Aβ ICV and isolating microglia from the brains, we have been able to establish the transcriptional response of microglia to Aβ in vivo and test how EP2 deletion in microglia affects this response. 8 month-old C57BL/6 mice, of the genotype CD11b-Cre; EP2+/+ or CD11b-Cre; EP2lox/lox, were injected I.C.V. with either Aβ or vehicle. 48 hours after injection, the mice were sacrificed and transcardially perfused with cold heparinized 0.9% NaCl. Brains were then removed from the mice and pooled, two brains of the same genotype per sample, to ensure adequate cell and RNA yield. The brains were then enzymatically dissociated for microglia isolation using the Neural Tissue Dissociation Kit (P), MACS Separation Columns (LS), and magnetic CD11b Microbeads from Miltenyi Biotec according to the manufacturer's protocol. Immediately after isolating the microglia, RNA was extracted from the cells for microarray analysis.
