Primary human and rat beta cells release the intracellular autoantigens GAD65, IA-2 and proinsulin in exosomes together with cytokine-induced enhancers of immunity

Jeffrey Alan Hubbell, Melody Swartz, Miriella Carmela Pasquier, Davide Demurtas, Sachiko Hirosue, Romain Hamelin, Steinunn Baekkeskov Hanahan, Michele De Palma, Edward Allen Phelps, Chiara Cianciaruso

The target autoantigens in several organ-specific autoimmune diseases, including type 1 diabetes (T1D), are intracellular membrane proteins, whose initial encounter with the immune system is poorly understood. Here we propose a new model for how these prot ...

Identification of Chlamydomonas Central Core Centriolar Proteins Reveals a Role for Human WDR90 in Ciliogenesis

Pierre Gönczy, Coralie Busso, Virginie Hamel, Florence Armand, Isabelle Fluckiger, Romain Hamelin, Paul Guichard

Centrioles are evolutionarily conserved macromolecular structures that are fundamental to form cilia, flagella, and centrosomes. Centrioles are 9-fold symmetrical microtubule-based cylindrical barrels comprising three regions that can be clearly distinguis ...

Malaria Parasite-Infected Erythrocytes Secrete PfCK1, the Plasmodium Homologue of the Pleiotropic Protein Kinase Casein Kinase 1

Marc Moniatte, Florence Armand, Romain Hamelin

Casein kinase 1 (CK1) is a pleiotropic protein kinase implicated in several fundamental processes of eukaryotic cell biology. Plasmodium falciparum encodes a single CK1 isoform, PfCK1, that is expressed at all stages of the parasite's life cycle. We have p ...

Identification of new Presenilin-1 phosphosites: implication for gamma-secretase activity and A beta production

Marc Moniatte, Patrick Fraering, Blanka Halamoda, Alexandre Matz, Mitko Dimitrov, Romain Hamelin, Sébastien Mosser

An important pathological hallmark of Alzheimer's disease (AD) is the deposition of amyloid-beta (A) peptides in the brain parenchyma, leading to neuronal death and impaired learning and memory. The protease -secretase is responsible for the intramembrane ...

A mammalian transcription factor-specific peptide repository for targeted proteomics

Jovan Simicevic, Marc Moniatte, Bart Deplancke, Romain Hamelin

Site-specific transcription factors (TFs) play an essential role in mammalian development and function as they are vital for the majority of cellular processes. Despite their biological importance, TF proteomic data is scarce in the literature, likely due ...

Quantitative Mass Spectrometry Reveals Plasticity of Metabolic Networks in Mycobacterium smegmatis

Marc Moniatte, Diego Chiappe, John McKinney, Tarun Chopra, Florence Armand, Romain Hamelin

Mycobacterium tuberculosis has a remarkable ability to persist within the human host as a clinically inapparent or chronically active infection. Fatty acids are thought to be an important carbon source used by the bacteria during long term infection. Catab ...

Characterization of the surfaceome of the metal-reducing bacterium Desulfotomaculum reducens

Elena Suvorova Buffat, Diego Chiappe, Rizlan Bernier-Latmani, Elena Cristina Dalla Vecchia, Romain Hamelin, Paul Pao-Yun Shao

Desulfotomaculum reducens strain MI-1 is a Gram-positive, sulfate-reducing bacterium also capable of reducing Fe(III). Metal reduction in Gram-positive bacteria is poorly understood. Here, we investigated Fe(III) reduction with lactate, a non-fermentable s ...

A quantitative telomeric chromatin isolation protocol identifies different telomeric states

Joachim Lingner, Marc Moniatte, Diego Chiappe, Larissa Grolimund, Florence Armand, Romain Hamelin, Eric Aeby

Telomere composition changes during tumourigenesis, aging and in telomere syndromes in a poorly defined manner. Here we develop a quantitative telomeric chromatin isolation protocol (QTIP) for human cells, in which chromatin is cross-linked, immunopurified ...

Inactivation of human adenovirus by UV and singlet oxygen as examined by quantitative protein mass spectrometry

Tamar Kohn, Florence Armand, Romain Hamelin, Franziska Sara Bosshard

Mechanisms of Human Adenovirus Inactivation by Sunlight and UVC Light as Examined by Quantitative PCR and Quantitative Proteomics

Tamar Kohn, Florence Armand, Romain Hamelin, Franziska Sara Bosshard

Human adenoviruses (HAdV) are important pathogens in both industrialized and developing nations. HAdV has been shown to be relatively resistant to monochromatic UVC. Polychromatic UVC, in contrast, is a more effective means of disinfection, presumably due ...

Involvement of Plasmodium falciparum protein kinase CK2 in the chromatin assembly pathway

Guillem Dayer, Marc Moniatte, Amit Sharma, Romain Hamelin

Background: Protein kinase CK2 is a pleiotropic serine/threonine protein kinase with hundreds of reported substrates, and plays an important role in a number of cellular processes. The cellular functions of Plasmodium falciparum CK2 (PfCK2) are unknown. Th ...

Activation of a PAK-MEK signalling pathway in malaria parasite-infected erythrocytes

Marc Moniatte, Romain Hamelin

P>Merozoites of malaria parasites invade red blood cells (RBCs), where they multiply by schizogony, undergoing development through ring, trophozoite and schizont stages that are responsible for malaria pathogenesis. Here, we report that a protein kinase-me ...
