Novel age related alterations revealed by a comparative kinetic transcriptome analysis of naïve CD4+ and CD8+ T cells from young and old animals.

ABSTRACT: Define,(a) intrinsic differences and (b) changes occuring upon TCR activation in genetic profiles of naive CD4+ and CD8+ T cells from young and old animals, to identify candidate genes altered in old T cells involved in impairement of immune response in order to restore immune function in the old.

Transcriptome analysis of young and old zebrafish ventricles

Project description:The gradual decline of tissue functionality is the main reason why humans suffer from age-related diseases. The prevalence for cardiovascular diseases increases with increasing age. In order to prevent age-related cardiac diseases, it is of importance to understand the respective age-associated risk factors. We have therefore compared the ventricular transcriptome of old and young hearts of the model organism zebrafish. We identified the immune system as activated in the old and found muscle organization to deteriorate upon aging. We show an accumulation of immune cells, mostly macrophages, in the old zebrafish ventricle.

Single-cell RNA-Seq of young, old and metformin-treated mouse muscle and adipose

Project description:Here we investigate the nature of cellular heterogeneity in the gene expression of aging and characterize the changes that metformin causes in mouse adipose and muscle at the single-cell resolution. The single cell transcriptomes of ~13,000 cells were captured using single-cell RNA-sequencing, resulting in gene expression data for 13 cell types from the visceral adipose tissue stromal-vascular fraction and ~5,000 cells from 12 cell types from the gastrocnemius muscle. The study design featured three groups of male C57BL/6J mice that corresponded to three-month-old controls (young), 18-month-old controls (old), and 18-month-olds treated with 1000 ppm (0.1% w/w) metformin for 6 weeks (treated). Our analyses demonstrate that metformin’s age-associated changes results in the modulation of an old to young expression profile via a cell type-specific manner. This reversion is demonstrated by significant changes observed in cell-type proportions and the degree of cell-cell heterogeneity. Additionally, metformin is known to restore the dysregulation due to age in autophagy and immune response in adipose, hypoxia in muscle, and inflammatory responses in both tissues. In our data, we detect evidence of these processes at play where endothelial cells, macrophages, and stem/progenitor cells respond most effectively to metformin’s gerotherapeutic response compared to other cell types. We further characterize metformin’s role in reverting age-associated cell-type-specific shifts in the transcriptional space by investigating changes in gene expression distributions and gene regulatory network dynamics.

Myelin proteome differences in old and young mice

Project description:Aging of the peripheral nervous system (PNS) is associated with structural and functional changes that lead to a reduction in regenerative capacity and the development of age-related peripheral neuropathy. Myelin is a central component in maintaining physiological peripheral nerve function, and differences in myelin maintenance, degradation, formation and clearance have been suggested to contribute to age-related PNS changes. In addition, recent proteomic studies have elucidated the complex composition of the total myelin proteome in health and its changes in neuropathy models. However, changes in the myelin proteome of peripheral nerves during ageing have not been investigated. Hence, the aim of this proteomics experiment was to define proteome changes in isolated myelin fractions during ageing, by investigating myelin proteome profiles from young (nerves from 2-3 month old mice) and old (nerves from 18 months old mice) nerves.

High-throughput sequencing for analysis of macropahges from old and young mice.

Project description:Immune cells are essential for proper fracture healing. The goal of this study was to compare the transcriptional profiles of the CD45+ immune cells isolated from the healing fracture callus of old (24 month) and young (3 month) mice (C57BL/6). Analysis of all CD45+ cells was completed via single cell RNAseq. Additional analysis of the macrophages involved in fracture healing in old and young mice was performed via bulk RNAseq. We show that there were multiple subpopulations of macrophages that were transcriptionally heterogenous and present simultaneously within the fracture callus tissue. Attenuated healing in the old mice was associated with a transcriptional profile that shifted towards more pro-inflammatory phenotypes.
