Acetate, a metabolic product of Heligmosomoides polygyrus, facilitates intestinal epithelial barrier breakdown in a FFAR2-dependent manner

Luc Xavier Marie Lebon, Nicola Harris, Mario Michael Zaiss, Julia Esser-von Bieren, Lalit Kumar Dubey

Approximately 2 billion people worldwide and a significant part of the domestic livestock are infected with soil-transmitted helminths, of which many establish chronic infections causing substantial eco-nomic and welfare burdens. Beside intensive research ...

Development of Sample-Adaptable Holders for Lightsheet Microscopy

Olivier Burri, Thierry Laroche, Arne Seitz, Lalit Kumar Dubey

Multi-user core microscopy facilities are often faced with the challenge to adapt or modify existing instruments. This is essential in order to fulfill the requirements of the user community, who wants to image a wide range of model organisms with varying ...

IL-4R alpha-Expressing B Cells Are Required for CXCL13 Production by Fibroblastic Reticular Cells

Nicola Harris, Lalit Kumar Dubey

Adaptive type 2 immune responses against the intestinal helminth Heligmosomoides polygyrus (Hp) require the interaction of follicle-associated CXCR5(+) dendritic cells with naive T cells in the draining mesenteric lymph nodes (mLNs). However, the source of ...

FIBCD1 Binds Aspergillus fumigatus and Regulates Lung Epithelial Response to Cell Wall Components

Lalit Kumar Dubey

Aspergillus fumigatus (A. fumigatus) is a ubiquitous fungus of clinical importance associated with development of various pulmonary diseases and allergic hypersensitivity reactions. It is protected against environmental stress by a cell wall that contains ...

Interactions between fibroblastic reticular cells and B cells promote mesenteric lymph node lymphangiogenesis

Nicola Harris, Lalit Kumar Dubey, Praneeth Karempudi

Lymphatic growth (lymphangiogenesis) within lymph nodes functions to promote dendritic cell entry and effector lymphocyte egress in response to infection or inflammation. Here we demonstrate a crucial role for lymphotoxin-beta receptor (LT beta R) signalin ...

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

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

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 ...

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

Alexis Rapin, Jacques Rougemont, Laure Menin, Luc Xavier Marie Lebon, Ilaria Mosconi, Nicola Harris, Benjamin John Marsland, Mario Michael Zaiss, Lalit Kumar Dubey, Alessandra Piersigilli, Andrew J. Macpherson

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 ...

Parasite Proximity Drives the Expansion of Regulatory T Cells in Peyer's Patches following Intestinal Helminth Infection

Luc Xavier Marie Lebon, Ilaria Mosconi, Nicola Harris, Mario Michael Zaiss, Julia Esser-von Bieren, Beatrice Volpe, Lalit Kumar Dubey

Helminth infections are typically chronic in nature; however, the exact molecular mechanisms by which these parasites promote or thwart host immunity remain unclear. Worm expulsion requires the differentiation of CD4(+) T cells into Th2 cells, while regula ...
