Elucidating the role of mammalian CLPP in mitochondrial translation regulation



The team led by Prof. Aleksandra Trifunovic is investigating the function of mitochondria in the development of disease and during aging. When mitochondria experience stress or when dysfunction occurs, they send signals to the cell nucleus, which launches different types of adaptive cell responses. Transcription factors are activated and stimulate the expression of specific sets of genes, whose products enable the cell to adapt to the changes. The scientists aim to understand this signaling cascade in detail.
