Development and validation of a multiplex real-time qPCR assay using GMP-grade reagents for leprosy diagnosis

Stewart Cole, Charlotte Avanzi, Thyago Leal Calvo

Author summaryLeprosy is a chronic dermato-neurological disease caused by Mycobacterium leprae, an obligate intracellular bacterium. Diagnosis of leprosy often relies on skin examinations for clinical signs, bacilli staining from skin smears and invasive s ...

Clocks do not tick in unison: isolation of Clock and vrille shed new light on the clockwork model of the sand fly Lutzomyia longipalpis

Antonio Carlos Alves Meireles Filho

Background: Behavior rhythms of insect vectors directly interfere with the dynamics of pathogen transmission to humans. The sand fly Lutzomyia longipalpis is the main vector of visceral leishmaniasis in America and concentrates its activity around dusk. De ...

The C-type Lectin Receptors Dectin-1, MR, and SIGNR3 Contribute Both Positively and Negatively to the Macrophage Response to Leishmania infantum

Johan Auwerx

Macrophages act as the primary effector cells during Leishmania infection through production of reactive oxygen species (ROS) and interleukin-1 beta (IL-1 beta). However, how macrophage-killing mechanisms are activated during Leishmania-macrophage interact ...

A secondary metabolite acting as a signalling molecule controls Pseudomonas entomophila virulence

Bruno Lemaitre, Onya Opota

Pseudomonas entomophila is an entomopathogenic bacterium that is lethal to Drosophila melanogaster within 1-2 days of ingestion of high doses. Flies orally infected with P. entomophila rapidly succumb despite the induction of both local and systemic immune ...

Potent and Selective Antiplasmodial Activity of the Cyanobacterial Alkaloid Nostocarboline and its Dimers

Karl Gademann

The quaternary β-carbolinium alkaloid nostocarboline from the cyanobacterium Nostoc 78-12A and ten bis-cationic dimeric derivatives were evaluated against four protozoan parasites and low micromolar values against Trypanosoma brucei, submicromolar values a ...

IL-21 receptor signaling is integral to the development of Th2 effector responses in vivo

Nicola Harris, Benjamin John Marsland

Interleukin 21 (IL-21) is a member of the common gamma-chain family of cytokines, which influence a broad spectrum of immunologic responses. A number of studies have examined the function of IL-21, but its specific role in Th1/Th2-cell differentiation and ...

Prevalence of local immune response against oral infection in a Drosophila/Pseudomonas infection model

Bruno Lemaitre

Pathogens have developed multiple strategies that allow them to exploit host resources and resist the immune response. To study how Drosophila flies deal with infectious diseases in a natural context, we investigated the interactions between Drosophila and ...

Intracellular targets of cyclin-dependent kinase inhibitors: identification by affinity chromatography using immobilised inhibitors

BACKGROUND: Chemical inhibitors of cyclin-dependent kinases (CDKs) have great therapeutic potential against various proliferative and neurodegenerative disorders. Olomoucine, a 2,6,9-trisubstituted purine, has been optimized for activity against CDK1/cycli ...

Expansion of gamma delta+ T cells in BALB/c mice infected with Leishmania major is dependent upon Th2-type CD4+ T cells

Michel Aguet, Friedrich Beermann, Anne Wilson

T cells belong to either the alpha beta+ or gamma delta+ lineage as defined by their antigen receptor. Although both T-cell subsets have been shown to be involved in the immune response to the parasite Leishmania major, very little is known about possible ...
