BACKGROUND:Acute flaccid myelitis (AFM) is characterised by rapid onset of limb weakness with spinal cord grey-matter abnormalities on MRI scan. We aimed to assess whether detection of enterovirus in respiratory or other specimens can help predict prognosis in children with AFM. METHODS:In this nationwide, longitudinal study, we evaluated the significance ... Read more >>

Modulation of monosodium urate crystal-induced responses in neutrophils by the myeloid inhibitory C-type lectin-like receptor: potential therapeutic implications.

Valérie Gagné, Louis Marois, Jean-Michel Levesque, Hugo Galarneau, Mireille H Lahoud, Irina Caminschi, Paul H Naccache, Philippe Tessier, Maria J G Fernandes,

INTRODUCTION: Monosodium urate crystals (MSU), the etiological agent of gout, are one of the most potent proinflammatory stimuli for neutrophils. The modulation of MSU-induced neutrophil activation by inhibitory receptors remains poorly characterized. The expression of the myeloid inhibitory C-type lectin-like receptor (MICL) in neutrophils is downregulated by several proinflammatory stimuli, ... Read more >>

The ubiquitin ligase c-Cbl down-regulates FcgammaRIIa activation in human neutrophils.

Louis Marois, Myriam Vaillancourt, Sébastien Marois, Sophie Proulx, Guillaume Paré, Emmanuelle Rollet-Labelle, Paul H Naccache,

Little is known about the mechanisms that arrest FcgammaRIIa signaling in human neutrophils once engaged by immune complexes or opsonized pathogens. In our previous studies, we observed a loss of immunoreactivity of Abs directed against FcgammaRIIa following its cross-linking. In this study, we report on the mechanisms involved in this ...

Crystal-induced neutrophil activation: X. Proinflammatory role of the tyrosine kinase Tec.

Oana Popa-Nita, Louis Marois, Guillaume Paré, Paul H Naccache,

OBJECTIVE: Monosodium urate monohydrate (MSU) crystals are among the most potent proinflammatory stimuli, and an innate immune inflammatory response to the crystal surface is involved in the pathogenesis of gouty arthritis. Release of the crystals into the joint cavity promotes an acute inflammation characterized by massive infiltration of neutrophils, which ... Read more >>

Hematopoietic cell kinase (Hck) isoforms and phagocyte duties - from signaling and actin reorganization to migration and phagocytosis.

Romain Guiet, Renaud Poincloux, Jerôme Castandet, Louis Marois, Arnaud Labrousse, Véronique Le Cabec, Isabelle Maridonneau-Parini,

The activity of hematopoietic cell kinase (Hck), a member of the Src family kinases, is modulated by regulatory mechanisms leading to distinct protein conformations with gradual levels of activity. Hck is mostly expressed in phagocytes as two isoforms, p59Hck and p61Hck, which show distinct subcellular localizations and trigger distinct phenotypes ... Read more >>
