Disturbed mitochondrial dynamics in CD8(+)TILs reinforce T cell exhaustion

Nicola Vannini, Marcela Rincón-Restrepo, Fabien Franco, George Coukos, Li Tang, Min Gao

Ho and colleagues report that mitochondrial dysfunction and impaired mitophagy triggered by the tumor microenvironment lead to subsequent epigenetic changes and cause permanent T cell exhaustion and dysfunction. The metabolic challenges present in tumors a ...

Measurement of Mitochondrial Mass and Membrane Potential in Hematopoietic Stem Cells and T-cells by Flow Cytometry

Nicola Vannini, Mukul Girotra, Olaia Maria Naveiras Torres-Quiroga, George Coukos, Alexandre Harari

A fine balance of quiescence, self-renewal, and differentiation is key to preserve the hematopoietic stem cell (HSC) pool and maintain lifelong production of all mature blood cells. In recent years cellular metabolism has emerged as a crucial regulator of ...

The NAD-Booster Nicotinamide Riboside Potently Stimulates Hematopoiesis through Increased Mitochondrial Clearance

Matthias Lütolf, Yannick Lionel Yersin, Vincent Trachsel, Bart Deplancke, Nicola Vannini, Johan Auwerx, Pedro Romero, Carlos Canto Alvarez, Martin Ehrbar, Mukul Girotra, Aurélien Laurent Jean-Charles Oggier, Dongryeol Ryu, Eija Riitta Pirinen, Olaia Maria Naveiras Torres-Quiroga, Pernille Yde Rainer, Gennady Nikitin, Vasco Ledebur de Antas de Campos, Joanna Ratajczak, Loïc Tauzin, Josefine Catharina Pedersen Tratwal, Federico Sizzano, George Coukos, Sonja Giger, Shanti Rojas-Sutterlin, Yang Li, Simone Ragusa

It has been recently shown that increased oxidative phosphorylation, as reflected by increased mitochondrial activity, together with impairment of the mitochondrial stress response, can severely compromise hematopoietic stem cell (HSC) regeneration. Here w ...

Specification of haematopoietic stem cell fate via modulation of mitochondrial activity

Matthias Lütolf, Aline Roch, Nicola Vannini, Johan Auwerx, Mukul Girotra, Olaia Maria Naveiras Torres-Quiroga, Gennady Nikitin, Vasco Ledebur de Antas de Campos, Sonja Giger

Haematopoietic stem cells (HSCs) differ from their committed progeny by relying primarily on anaerobic glycolysis rather than mitochondrial oxidative phosphorylation for energy production. However, whether this change in the metabolic program is the cause ...
