Exploiting Old Pathogens to Create New Therapeutics

Nicola Harris, Tiffany Babette Angélique Bouchery

Intestinal worms are well known for their potent immuno-modulatory capacity. In a recent study, Navarro et al. (2016) identify a secreted hookworm protein that can suppress allergic responses in both mice and humans. This represents an exciting strategy fo ...

Lymphotoxin-Dependent B Cell-FRC Crosstalk Promotes De Novo Follicle Formation and Antibody Production following Intestinal Helminth Infection

Nicola Harris, Lalit Kumar Dubey, Ilaria Mosconi, Luc Xavier Marie Lebon

Secondary lymphoid tissues provide specialized niches for the initiation of adaptive immune responses and undergo a remarkable expansion in response to inflammatory stimuli. Although the formation of B cell follicles was previously thought to be restricted ...

Nanoparticle conjugation enhances the immunomodulatory effects of intranasally delivered CpG in house dust mite-allergic mice

Jeffrey Alan Hubbell, Melody Swartz, Alexandre de Titta, Marie Ballester, Laura Jeanbart

An emerging strategy in preventing and treating airway allergy consists of modulating the immune response induced against allergens in the lungs. CpG oligodeoxynucleotides have been investigated in airway allergy studies, but even if promising, efficacy re ...

The Intestinal Microbiota Contributes to the Ability of Helminths to Modulate Allergic Inflammation

Nicola Harris, Laure Menin, Alessandra Piersigilli, Alexis Rapin, Jacques Rougemont, Mario Michael Zaiss, Lalit Kumar Dubey, Ilaria Mosconi, Luc Xavier Marie Lebon

Intestinal helminths are potent regulators of their host's immune system and can ameliorate inflammatory diseases such as allergic asthma. In the present study we have assessed whether this anti-inflammatory activity was purely intrinsic to helminths, or w ...

Photodynamic drug delivery enhancement in tumours does not depend on leukocyte-endothelial interaction in a human mesothelioma xenograft model

Hubert van den Bergh, Elodie Debefve, Hans-Anton Lehr

OBJECTIVES: The pre-treatment of tumour neovessels by low-level photodynamic therapy (PDT) improves the distribution of concomitantly administered systemic chemotherapy. The mechanism by which PDT permeabilizes the tumour vessel wall is only partially know ...

Cre-mediated cell ablation contests mast cell contribution in models of antibody- and T cell-mediated autoimmunity

Nicola Harris

Immunological functions of mast cells remain poorly understood. Studies in Kit mutant mice suggest key roles for mast cells in certain antibody- and T cell-mediated autoimmune diseases. However, Kit mutations affect multiple cell types of both immune and n ...
