PPS nanoparticles as versatile delivery system to induce systemic and broad mucosal immunity after intranasal administration

Eleonora Simeoni, Jeffrey Alan Hubbell, Melody Swartz, Mikaël Martino, Armando Stano

Degradable polymer nanoparticles (NPs, 50nm) based on polypropylene sulfide (PPS) were conjugated to thiolated antigen and adjuvant proteins by reversible disulfide bonds and evaluated in mucosal vaccination. Ovalbumin was used as a model antigen, and anti ...

Spontaneous phthiocerol dimycocerosate-deficient variants of Mycobacterium tuberculosis are susceptible to gamma interferon-mediated immunity

John McKinney, Swapna Uplekar, Anna De Graff Tischler

Onset of the adaptive immune response in mice infected with Mycobacterium tuberculosis is accompanied by slowing of bacterial replication and establishment of a chronic infection. Stabilization of bacterial numbers during the chronic phase of infection is ...

Listeria monocytogenes is sensed by the NLRP3 and AIM2 inflammasome

Andrea Ablasser

The inflammasome pathway functions to regulate caspase-1 activation in response to a broad range of stimuli. Caspase-1 activation is required for the maturation of the pivotal pro-inflammatory cytokines of the pro-IL-1beta family. In addition, caspase-1 ac ...

An unexpected role for RNA in the recognition of DNA by the innate immune system

Andrea Ablasser

A central function of our innate immune system is to sense microbial pathogens through the presence of their nucleic acid genomes or their transcriptional or replicative activity. In mammals, a receptor-based system is mainly responsible for the detection ...

AIM2 recognizes cytosolic dsDNA and forms a caspase-1-activating inflammasome with ASC

Andrea Ablasser

The innate immune system senses nucleic acids by germline-encoded pattern recognition receptors. RNA is sensed by Toll-like receptor members TLR3, TLR7 and TLR8, or by the RNA helicases RIG-I (also known as DDX58) and MDA-5 (IFIH1). Little is known about s ...

Shigella phagocytic vacuolar membrane remnants participate in the cellular response to pathogen invasion and are regulated by autophagy

Françoise Gisou van der Goot Grunberg, Nicolas Dupont

Intracellular pathogens like Shigella flexneri enter host cells by phagocytosis. Once inside, the pathogen breaks the vacuolar membrane for cytosolic access. The fate and function of the vacuolar membrane remnants are not clear. Examining Shigella-infected ...

Mechanisms of Apoptosis in Retinitis Pigmentosa

Mutations in humans are associated with several forms of inherited retinal dystrophies, such as Retinitis Pigmentosa which lead to retinal cell death and irreversible loss of vision. Genes involved in affected patients mainly encode proteins related to vis ...

Maturation modulates caspase-1-independent responses of dendritic cells to Anthrax lethal toxin

Françoise Gisou van der Goot Grunberg

Anthrax lethal toxin (LT) contributes to the immune evasion strategy of Bacillus anthracis by impairing the function of cells of the immune system, such as macrophages and dendritic cells (DCs). Macrophages from certain inbred mice strains undergo rapid de ...

Intracellular pattern-recognition receptors

Etienne Meylan

The last ten years of research in the field of innate immunity have been incredibly fertile: the transmembrane Toll-like receptors (TLRs) were discovered as guardians protecting the host against microbial attacks and the emerging pathways characterized in ...

A serpin that regulates immune melanization in the respiratory system of Drosophila

Bruno Lemaitre

Epithelial tissues facing the external environment are essential to combating microbial infection. In addition to providing a physical barrier, epithelial tissues mount chemical defenses to prevent invasion of internal tissues by pathogens. Here, we descri ...
