Project description:Aged microglia contribute to maladaptive inflammation, but little is known about their progression from homeostasis to dysfunction during aging. Here, we analyze the spatiotemporal kinetics of microglial aging in the hippocampus. Spatially, the dynamics of age-related inflammatory changes in microglia vastly differ across adjoining regions. Using single cell RNA-Sequencing and in vitro approaches, we find that microglia aging proceeds progressively through functional intermediate states that are necessary for inflammatory activation.
Project description:The study consists of three parts: 1) normal aging in liver and skin (cross-sectional); 2) treatment with rotenone in brain, liver and skin; 3) longitudinal study of 45 fish with different ages at their death measured at two different time points by fin clipping Jena Centre for Systems Biology of Ageing - JenAge (www.jenage.de)
