Endogenous tryptophan (Trp) metabolites have an important role in mammalian gut immune homeostasis, yet the potential contribution of Trp metabolites from resident microbiota has never been addressed experimentally. Here, we describe a metabolic pathway whereby Trp metabolites from the microbiota balance mucosal reactivity in mice. Switching from sugar to(More)
During the last decade, significant technological improvements in mass spectrometry have had a great impact on drug discovery. The development of matrix-assisted laser desorption/ionization imaging mass spectrometry (MALDI-IMS) has set a new frontier for the study of the distribution of endogenous and exogenous molecules present within a tissue. MALDI-IMS(More)
Non-specific lipid-transfer proteins (nsLTPs) are major human allergens in many plant species, albeit their role in plant biochemistry is still undefined. They are found in many plant species, either as one or several isoforms according to the species, and usually they are found to concentrate in the outer part of the fruits. In this work, the(More)
BACKGROUND AND PURPOSE Dexpramipexole, a drug recently tested in patients with amyotrophic lateral sclerosis (ALS,) is able to bind F1Fo ATP synthase and increase mitochondrial ATP production. Here, we have investigated its effects on experimental ischaemic brain injury. EXPERIMENTAL APPROACH The effects of dexpramipexole on bioenergetics, Ca2+ fluxes,(More)
