Helminth products bypass the need for TSLP in Th2 immune responses by directly modulating dendritic cell function

Thymic stromal lymphopoietin (TSLP) is an interleukin (IL)-7-like cytokine, mainly expressed by epithelial cells, and key to the development of allergic responses. The well-documented involvement of TSLP in allergy has led to the conviction that TSLP promo ...

IL-13 attenuates gastrointestinal candidiasis in normal and immunodeficient RAG-2(-/-) mice via peroxisome proliferator-activated receptor-gamma activation

Johan Auwerx

We recently demonstrated that in vitro peroxisome proliferator-activated receptor-gamma (PPARgamma) activation of mouse peritoneal macrophages by IL-13 or PPARgamma ligands promotes uptake and killing of Candida albicans through mannose receptor overexpres ...

Intestinal bacteria condition dendritic cells to promote IgA production

Nicola Harris

Immunoglobulin (Ig) A represents the predominant antibody isotype produced at the intestinal mucosa, where it plays an important role in limiting the penetration of commensal intestinal bacteria and opportunistic pathogens. We show in mice that Peyer's Pat ...

Functionalization of polysulfide nanoparticles and their performance as circulating carriers

Jeffrey Alan Hubbell, Nicola Tirelli, Annemie Rehor

We here present an evaluation of the carrier performance of nanoparticles that are biofunctional, i.e. derivatized to provide a controlled biological activity, and environmentally responsive, since they respond to the presence of oxidants. In particular, w ...

A novel drug discovery concept for tuberculosis: inhibition of bacterial and host cell signalling

Stewart Cole, Edina Rita Székely, Gabor Nemeth

The Mycobacterium tuberculosis genome encodes for eleven eukaryotic-like Ser/Thr protein kinases. At least three of these (PknA, PknB and PknG) are essential for bacterial growth and survival. PknG is secreted by pathogenic mycobacteria, in macrophages to ...

Nanoparticle based Tuberculosis vaccine

Bastien Schyrr

Despite the widespread use of Bacille de Calmette et Guérin (BCG) for over50 years, tuberculosis (TB) continues to be a major global health problem, especially in developing countries. Indeed BCG as been shown to reduce infant mortality, but demonstrated v ...

Sustained activation and tumor targeting of NKT cells using a CD1d-anti-HER2-scFv fusion protein induce antitumor effects in mice

Florian Maria Wurm, Lucia Baldi Unser

Invariant NKT (iNKT) cells are potent activators of DCs, NK cells, and T cells, and their antitumor activity has been well demonstrated. A single injection of the high-affinity CD1d ligand α-galactosylceramide (αGalCer) leads to short-lived iNKT cell activ ...

Polyclonal and specific antibodies mediate protective immunity against enteric helminth infection

Nicola Harris, Andrew J. Macpherson

Anti-helminth immunity involves CD4+ T cells, yet the precise effector mechanisms responsible for parasite killing or expulsion remain elusive. We now report an essential role for antibodies in mediating immunity against the enteric helminth Heligmosomoide ...

Integrins and the activation of latent transforming growth factor beta1 - an intimate relationship

Boris Hinz, Pierre Jean Arnould Wipff

Integrins are crucial for the ability of cells to sense mechanical perturbations and to transmit intracellular stress to their environment. We here review the more recently discovered role of integrins in activating the pleiotrophic cytokine transforming g ...

Superparamagnetic iron oxide binding and uptake as imaged by magnetic resonance is mediated by the integrin receptor Mac-1 (CD11b/CD18): Implications on imaging of atherosclerotic plaques

Heinrich Hofmann, Alke Fink, Benedikt Steitz

Introduction: Superparamagnetic iron oxide nanoparticles (SPIONs) have been successfully used for magnetic resonance imaging (MRI) of atherosclerotic plaques. Endocytosis into monocytes/macrophages has been proposed as the mechanism for SPION uptake, but a ...
