Multi-modal analysis of the aging mouse lung at cellular resolution

ABSTRACT: A) Whole lung tissue from 24 months (n=7) and 3 months old (n=8) mice was dissociated and single-cell mRNAseq libraries generated with Drop-Seq. B) Bulk RNA-seq data was generated from whole mouse lung tissue of old (n=3) and young (n=3) samples. C) Bulk RNA-seq data was generated from flow-sorted macrophages from old (n=7) and young (n=5) mice and flow-sorted epithelial cells from old (n=4) and young (n=4) mice.

Gene expression profile of Age associated B cells, Follicular B cells, and B1 cells

Project description:We performed gene expression profile of different B cell populations found in old (18 months old) C57BL/6 female mouse (B1 cells were recovered from both young and old C57BL/6 mice). Mice were naïve and healthy (no autoimmunity was detected at the time of the experiment). Different B cell populations were sorted using flow cytometry and RNA was isolated.

Characterisation of young, old and old repopulating microglia in spinal cord and brain of C57BL/6 wild type male mice

Project description:To address whether, after depletion by Csf1r inhibition, microglia repopulating the CNS revert to a “younger” phenotype, we treated a group of 23 months old mice with the Csf1r inhibitor for 5 days and let microglia repopulate the central nervous system for 7 days. Young (3 months old) and old (23 months old) mice were included as controls. After the repopulation time, whole spinal cord samples and Fluorescence Activated Sorting (FACS)-sorted microglia cells from brain tissue were collected to perform bulk transcriptome (RNAseq) analysis. Analysis of whole spinal cord suggested that repopulating microglia tend to re-acquire its original aged phenotype. Gene expression in FACS-sorted microglia was then analyzed to better characterize its intrinsic phenotype after repopulation. In contrast to the whole spinal cord samples, old and old-treated replicates separated in Principal Component Analysis, suggesting that repopulating microglia displayed a different phenotype compared to old microglia.

Central nervous system-associated macrophages modulate the immune response following stroke in aged mice

Project description:To study the differential role of central nervous system-associated macrophages (CAMs) in neuroinflammation after stroke between young and aged mice, we FACS sorted CD3-CD11b+CD45+CD206+ CAMs from brains of C57BL/6 mice aged 2 months (young) and 18 months (old)

Taz protects aged hematopoietic stem cells from exhaustion [bulk RNA-seq II]

Project description:We report here the analysis of young and aged hematopoietic stem and progenitor cells (HSPCs) by transcriptional profiling (bulk RNA-Seq, CITE-Seq) and chromatin profiling (ATAC-Seq, scATAC-Seq). We use here a Clca3a1 as a surface marker to further fractionate HSPCs. Old (Clca3a1_high) hematopoietic stem cells (HSCs) were isolated by flow cytometry, transduced ex vivo with different shRNA constructs (shRen, shTaz_Seq1, shTaz_Seq2) and transplanted into lethally irradiated mice. Four months after transplantation, transduced (GFP+)HSPCs were isolated by flow cytometry and subsequently analyzed by low input RNA-Seq. Per sample two mice were pooled in order to obtain sufficient RNA for library prep.

single cell RNA sequencing of hematopoietic stem cells aged in old and young niches

Project description:Purpose: Compare the transcriptome of hematopoietic stem cells (HSCs) that were aged in old and young niches Methods: barcoded GFP+ HSCs were FACS-sorted from a) three recipient mice 15 months post transplantation, and b) six serial transplantation recipient mice 5 months after the 8th transplantation, then subjected to processed using the Chromium Single-cell 3′ v2 Library Kit (10× Genomics, Pleasanton, CA) following the manufacturer’s instructions Results: we obtained transcriptomes of about 12k HSCs aged in young niche, and about 10k HSCs aged in old niche, with the average sequencing depth at close to 50k reads per cell Conclusions: we identified striking differences in gene expression profiles 1) between HSCs aged in young niches from mice with early aging and from mice with delayed aging, and 2) between HSCs aged in old niches and young niches when mice exhibited hematopoietic aging phenotype

scRNA-seq analysis of mouse splenic CD8 T cells 1 month post transfer of CD8 T cells from 3 months old donor into 24 months old recipient

Project description:Aging is associated with systemic chronic inflammation (inflammaging) that leads to impaired physiological functions and vulnerability to several diseases. However, underlying alterations in aged immune system resulting in gradual loss of immune fitness remain unclear. Using a combination of CD8 T cell transfer from young to old and from old to young mice and single-cell RNA sequencing, we characterized the age-associated alterations in CD8 T cells. We transferred 2 millions of purified CD8+ T cells pooled from 3 CD45.1 C57BL/6J 3 months old female mice (donor) by i.v. injection into CD45.2 C57BL/6J 24 months old female mouse (recipient) and sorted CD45.1+CD3e+CD8a+ and CD45.2+CD3e+CD8a+ T cells from the spleen 1 month post transfer to perform scRNA/TCR-seq.

LC-MS/MS analysis of isolated murine brain endothelial cells (BECs) from 3-, 6-, 12-, and 18-months-old mice and Apoe-KO mice at 3 months followed by label-free quantification (LFQ)

Project description:Age-related decline in brain endothelial cell (BEC) function critically contributes to cerebrovascular and neurodegenerative disease. Comprehensive atlases of the BEC transcriptome have become available but results from proteomic profiling are lacking. To gain insights into endothelial pathways affected by aging, we developed a magnetic-activated cell sorting (MACS)-based mouse BEC enrichment protocol compatible with high-resolution mass-spectrometry based proteomics. In this experiment, first we have compared MACS sorted BECs across multiple time points between 3 and 18 months of age. Using unsupervised cluster analysis, we found a segregation of age-related protein dynamics with biological functions including a downregulation of vesicle-mediated transport. Our approach uncovered changes not picked up by transcriptomic studies such as accumulation of vesicle cargo and receptor ligands including Apoe. Therefor in our next proteomics experiment we compared BECs from 3-months-old Apoe-KO and WT mice and found 111 and 103 proteins to be up- and downregulated, respectively. Comparing the BEC proteomic signature of young Apoe-KO mice with the signature of aged (18-months-old) WT mice we found a positive correlation suggesting an accelerating effect of Apoe deficiency on BEC aging.

An aging-like phenotype occurs in Tif1γ-/- hematopoietic stem cells

Project description:To determine whether an accelerated aging-like phenotype occurs in hematopoiesis of young Tif1γ-/- mice (4 months old), we purified 200,000 hematopoietic stem cells (LSK: Lineage negative, Sca1+, c-Kit+) from Tif1γ-/- mice and performed high-throughput mRNA sequencing (RNA-seq). We compared this transcriptome to physiological aging by creating two other RNAseq libraries from young (4 months old) and old (20 months old) wild type mice.
