Exploring the role of cGAS-STING-mediated inflammation in age-associated neurodegeneration and antitumor immunity

Inflammation stands as a dynamic and intricate biological process, promoting vital defence mechanisms against harmful stimuli, including infections and injuries, to drive pathogen clearance and healing. On one hand, these responses can manifest acutely and ...

Detecting the metabolism of individual yeast mutant strain cells when aged, stressed or treated with antioxidants with diamond magnetometry

Mayeul Sylvain Chipaux

Free radicals play a key role in the ageing process. However, free radicals are small, reactive and short lived and thus challenging to measure. We utilize a new technique called diamond magnetometry for this pur-pose. We make use of nitrogen vacancy cente ...

NAD(+) homeostasis in health and disease

Johan Auwerx, Mario Romani, Elena Katsyuba, Dina Hofer

The conceptual evolution of nicotinamide adenine dinucleotide (NAD(+)) from being seen as a simple metabolic cofactor to a pivotal cosubstrate for proteins regulating metabolism and longevity, including the sirtuin family of protein deacylases, has led to ...

Protocol for the PreventIT feasibility randomised controlled trial of a lifestyle-integrated exercise intervention in young older adults

Kamiar Aminian, Anisoara Ionescu

Introduction The European population is rapidly ageing. In order to handle substantial future challenges in the healthcare system, we need to shift focus from treatment towards health promotion. The PreventIT project has adapted the Lifestyle-integrated Ex ...

The chromatin remodeling factor ISW-1 integrates organismal responses against nuclear and mitochondrial stress

Johan Auwerx, Maroun Bou Sleiman

Age-associated changes in chromatin structure have a major impact on organismal longevity. Despite being a central part of the ageing process, the organismal responses to the changes in chromatin organization remain unclear. Here we show that moderate dist ...

Cell lineage tracing in human tissues using somatic mitochondrial mutations

Paul Refinetti

Lineage tracing is a basic concept in developmental biology, as well as diseases related to organ development. A reliable method to track cell lineages in human tissues has the potential to greatly contribute to the fields of oncogenesis, tissue renewal, a ...

Mitochondria and Epigenetics Crosstalk in Homeostasis and Stress

Johan Auwerx

Through epigenetic mechanisms cells integrate environmental stimuli to fine-tune gene expression levels. Mitochondrial function is essential to provide the intermediate metabolites necessary to generate and modify epigenetic marks in the nucleus, which in ...

CMG2/ANTXR2 regulates extracellular collagen VI which accumulates in hyaline fibromatosis syndrome

Françoise Gisou van der Goot Grunberg, Béatrice Kunz, Laurence Gouzi Abrami, Julie Deuquet Ariosa, Alessandra Piersigilli, Jérôme Bürgi

Loss-of-function mutations in capillary morphogenesis gene 2 (CMG2/ANTXR2), a transmembrane surface protein, cause hyaline fibromatosis syndrome (HFS), a severe genetic disorder that is characterized by large subcutaneous nodules, gingival hypertrophy and ...

Modelling of current and temperature effects on supercapacitors ageing. Part II: State-of-Health assessment

Mario Paolone, Dimitri Torregrossa

This second part of the paper proposes a model for predicting the State-of-Health (SOH) of electrochemical double layers supercapacitors (SCs) during combined high-pulsed power cycling and high-temperature life endurance stresses. The evolutions of the SC ...

Dietary restriction and Sirtuin 1 in metabolic health: connections and divergences

Carlos Canto Alvarez

Aging is the major risk factor for a constellation of multifactorial diseases, including insulin resistance, diabetes and cardiovascular complications. Dietary restriction has been shown to delay or prevent the manifestation of age-related health decline, ...
