Differential expression patterns and transport characteristics of aged cells

Ageing is associated with a number of diseases and manifests itself at the organ level (e.g. the morphological changes in the skin) as well as cellular level. Cellular function is dependent on correct delivery of proteins to their destinations, which is especially apparent in the ageing brain where axonal and dendritic transport is impaired. The underlying causes of this impairment most likely are due to changes to intracellular organelles, which are processing the proteins for secretion, i.e. the Golgi apparatus. Fragmentation of the Golgi has been implicated in functional and structural impairments of axons, presynaptic terminals and postsynaptic dendritic spines, which have been observed in neurodegenerative diseases and ageing.

The project aims to analyse key components of the intracellular trafficking machinery in aged cells to identify alterations associated with ageing. Special attention will be given to the analysis of protein lipid modifications in aged cells with the long-term aim of finding intervention possibilities. We have evidence that budding of transport vesicles from the Golgi apparatus in aged cells is altered and will use advanced imaging techniques to establish Golgi transport kinetics in control and aged cells in addition to biochemical Golgi transport assays. Furthermore, we have a system established in our laboratory to purify intracellular organelles and transport vesicles. We will use these purified fractions to analyse alterations in protein modifications by nano liquid chromatography - tandem mass spectrometry (Nano LC-MS/MS).
