Comparative RNA-Seq analyses ofDrosophilaplasmatocytes reveal gene specific signatures in response to clean injury and septic injury

Bruno Lemaitre, Jan Paul Dudzic, Elodie Julie Virginie Ramond

Drosophila melanogaster's blood cells (hemocytes) play essential roles in wound healing and are involved in clearing microbial infections. Here, we report the transcriptional changes of larval plasmatocytes after clean injury or infection with the Gram-neg ...

Early sepsis diagnosis via protein and miRNA biomarkers using a novel point-of-care photonic biosensor

Hatice Altug, Alexander Belushkin

y Sepsis is a condition characterized by a severe stage of blood-infection often leading to tissue damage, organ failure and finally death. Fast diagnosis and identification of the sepsis stage (sepsis, severe sepsis or septic shock) is critical for the pa ...

Memory B Cells Activate Brain-Homing, Autoreactive CD4(+) T Cells in Multiple Sclerosis

Jian Wang, Christian Hammer

Multiple sclerosis is an autoimmune disease that is caused by the interplay of genetic, particularly the HLA-DR15 haplotype, and environmental risk factors. How these etiologic factors contribute to generating an autoreactive CD4(+) T cell repertoire is no ...

The melanization reaction in Drosophila: More than black or white

Jan Paul Dudzic

The melanization reaction is a rapid and important immune mechanism in arthropods. It results in the production of melanin at the site of injury and around invading microbes. The enzymes responsible for melanogenesis are phenoloxidases (PO), which catalyze ...

Pathogenic commonalities between spinal muscular atrophy and amyotrophic lateral sclerosis: Converging roads to therapeutic development

Bernard Schneider

Spinal muscular atrophy (SMA) and amyotrophic lateral sclerosis (ALS) are the two most common motoneuron disorders, which share typical pathological hallmarks while remaining genetically distinct. Indeed, SMA is caused by deletions or mutations in the surv ...

Exome Sequencing Reveals Primary Immunodeficiencies in Children with Community-Acquired Pseudomonas aeruginosa Sepsis

Jacques Fellay, Istvan Bartha, Samira Asgari, Christoph Berger, Paul Jack Mc Laren, Richard Wong

One out of three pediatric sepsis deaths in high income countries occur in previously healthy children. Primary immunodeficiencies (PIDs) have been postulated to underlie fulminant sepsis, but this concept remains to be confirmed in clinical practice. Pseu ...

Sensing Gram-negative bacteria: a phylogenetic perspective

Bruno Lemaitre

Gram-negative bacteria represent a major group of pathogens that infect all eukaryotes from plants to mammals. Gram-negative microbe-associated molecular patterns include lipopolysaccharides and peptidoglycans, major immunostimulatory determinants across p ...

Remote Control of Intestinal Stem Cell Activity by Haemocytes in Drosophila

Bruno Lemaitre, Jean Philippe Boquete, Jan Paul Dudzic, Sveta Chakrabarti, Xiaoxue Li, Esther Jeanne Collas

The JAK/STAT pathway is a key signaling pathway in the regulation of development and immunity in metazoans. In contrast to the multiple combinatorial JAK/STAT pathways in mammals, only one canonical JAK/STAT pathway exists in Drosophila. It is activated by ...

TIE2-expressing monocytes/macrophages regulate revascularization of the ischemic limb

Michele De Palma, Daniela Biziato

A third of patients with critical limb ischemia (CLI) will eventually require limb amputation. Therapeutic neovascularization using unselected mononuclear cells to salvage ischemic limbs has produced modest results. The TIE2-expressing monocytes/macrophage ...

Long-range activation of systemic immunity through peptidoglycan diffusion in Drosophila

Bruno Lemaitre, David Welchman

The systemic immune response of Drosophila is known to be induced both by septic injury and by oral infection with certain bacteria, and is characterized by the secretion of antimicrobial peptides (AMPs) into the haemolymph. To investigate other possible r ...
