Dual action of L-Lactate on the activity of NR2B-containing NMDA receptors: from potentiation to neuroprotection

Pierre Magistretti, Igor Allaman, Pierre Marquet, Pascal Jourdain, Kaspar Rothenfusser

L-Lactate is a positive modulator of NMDAR-mediated signaling resulting in plasticity gene induction and memory consolidation. However, L-Lactate is also able to protect neurons against excito-toxic NMDAR activity, an indication of a mitigating action of L ...

Quantitative phase-digital holographic microscopy: a new imaging modality to identify original cellular biomarkers of diseases

Pierre Magistretti, Christian Depeursinge, Benjamin Rappaz, Pierre Marquet, Pascal Jourdain, Kaspar Rothenfusser

Quantitative phase microscopy (QPM) has recently emerged as a powerful label-free technique in the field of living cell imaging allowing to non-invasively measure with a nanometric axial sensitivity cell structure and dynamics. Since the phase retardation ...

L-Lactate protects neurons against excitotoxicity: implication of an ATP-mediated signaling cascade

Pierre Magistretti, Igor Allaman, Pierre Marquet, Pascal Jourdain, Kaspar Rothenfusser

Converging experimental data indicate a neuroprotective action of L-Lactate. Using Digital Holographic Microscopy, we observe that transient application of glutamate (100 μM; 2 min) elicits a NMDA-dependent death in 65% of mouse cortical neurons in culture ...
