FOR 885: Neuronal Protein Turnover
Zusammenfassung der Projektergebnisse
The Research Unit concentrated on studying neuronal protein turnover under physiological and pathophysiological conditions, specifically investigating 1) molecular pathways involved in neuron-specific protein degradation, 2) contribution of neuronal protein turnover in modulating neuronal excitability, 3) role of impaired neuronal protein homeostasis on neuronal function. The research unit used an interdisciplinary approach bringing together experts from cell biology, biochemistry, molecular biology and neuropathology from Hamburg and from Cologne. Together we showed that specific mechanisms of protein turnover are highly regulated in neurons and the interplay of these mechanisms is essential to maintain neuronal protein homeostasis, the prerequisite for normal brain function. Disturbance of this highly regulated network, be it through ageing mechanisms or through accumulation of misfolded proteins in neurodegenerative disease, can only be compensated for a limited amount of time. Consequences of disturbed neuronal protein turnover are loss of neuronal function and neurodegeneration and follow non-linear dynamics. The data generated by this research unit have contributed to a better understand of the molecular mechanisms underlying dementia and will help in devising strategies to accomplish healthy aging.
