Cellular Senescence is most often induced as a response to persistent DNA damage and telomere dysfunction, leading to a massive cellular re-programming including hyper-production of reactive oxygen species (ROS) and secretion of bioactive peptides known as the senescence associated secretory phenotype (SASP). It occurs in vivo and contributes to age-related diseases.
As part of my PhD, I have demonstrate that ageing mice neurons show multiple hallmarks of cell senescence. Moreover, I proved that this phenotype can be induced by telomere-dysfunction and is dependent on cyclin-kinase inhibitor p21. This was the first time that a senescent-like state was observed in post-mitotic neurons in vivo and has led to the recent proposal by several reputed researchers of a redefinition of senescence as a phenotype not exclusive to proliferation competent cells. Furthermore, I have shown how cellular senescence induced by genotoxic or oxidative stress depends on chronic DNA-damage signalling from irreparable damage to telomeres. This work showed that telomere-associated DNA damage foci (TAF) existed irrespectively of telomere length and presence of telomerase in a variety of mice tissues and that TAF are a sensitive and robust marker for senescence. More recently, I have demonstrated that nfkb1-/- mice develop chronic systemic inflammation which aggravates cell senescence in various tissues, inducing an accelerated ageing phenotype and decreasing lifespan. This paper establishes a link between chronic inflammation, cellular senescence and ageing.
My current research focuses on senescence during brain ageing and in neurodegenerative diseases like Alzheimer’s and Parkinson’s disease. Age is the single most relevant factor for developing neurodegenerative diseases which contribute to significant cognitive decline. I have demonstrated that cellular senescence occurs during brain ageing. However, it is still unknown how senescence in the brain impacts on its function during ageing. I aim to understand exactly how cellular senescence contributes to brain ageing and age-related cognitive decline.
Additionally, cellular senescence is a major contributor to age related tissue degeneration and has been shown to be involved in non-alcoholic fatty liver disease (NAFLD), but the mechanisms driving NAFLD are largely unknown. I aim to understand how cellular senescence might contribute to liver disease and if elimination of senescent cells could be used as a therapy to slow down, counteract NAFLD or prevent progression of NAFLD to HCC.
In the last 3 years I supervised two undergraduate students, 2 master students and I am supervising three PhD students (Mikolaj Ogrodnik, Edward Fielder, Melanie Weigand).
