Tetracycline-induced mitohormesis mediates disease tolerance against influenza

Elena Katsyuba, Alexis Rapin, Johan Auwerx, Nicola Harris, Adrienne Joëlle Laurence Mottis, Davide D'Amico, Yang Li, Gaby El Alam

Mitohormesis defines the increase in fitness mediated by adaptive responses to mild mitochondrial stress. Tetracyclines inhibit not only bacterial but also mitochondrial translation, thus imposing a low level of mitochondrial stress on eukaryotic cells. We ...

Novel High-Throughput Fluorescence-Based Assay for the Identification of Nematocidal Compounds That Target the Blood-Feeding Pathway

Gerardo Turcatti, Marc Chambon, Nicola Harris, Anthony Marchand, Tiffany Babette Angélique Bouchery, Mati André Marie Moyat

Hookworm infections cause a neglected tropical disease (NTD) affecting ~740 million people worldwide, principally those living in disadvantaged communities. Infections can cause high morbidity due to their impact on nutrient uptake and their need to feed o ...

beta-Glucan receptors on IL-4 activated macrophages are required for hookworm larvae recognition and trapping

Nicola Harris, Julia Esser-von Bieren, Beatrice Volpe, Tiffany Babette Angélique Bouchery, Mati André Marie Moyat

Recent advances in the field of host immunity against parasitic nematodes have revealed the importance of macrophages in trapping tissue migratory larvae. Protective immune mechanisms against the rodent hookworm Nippostrongylus brasiliensis (Nb) are mediat ...

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 ...

Small intestinal resident eosinophils maintain gut homeostasis following microbial colonization

Florence Armand, Nicola Harris, Romain Hamelin, Kathleen Shah, Mati André Marie Moyat

The intestine harbors a large population of resident eosinophils, yet the function of intestinal eosinophils has not been explored. Flow cytometry and whole-mount imaging identified eosinophils residing in the lamina propria along the length of the intesti ...

Hookworms Evade Host Immunity by Secreting a Deoxyribonuclease to Degrade Neutrophil Extracellular Traps

Manuel Kulagin, Arne Seitz, Nicola Harris, Romain Guiet, Beatrice Volpe, Kathleen Shah, Tiffany Babette Angélique Bouchery, Mati André Marie Moyat

Hookworms cause a major neglected tropical disease, occurring after larvae penetrate the host skin. Neutrophils are phagocytes that kill large pathogens by releasing neutrophil extracellular traps (NETs), but whether they target hookworms during skin infec ...

Infection with a small intestinal helminth, Heligmosomoides polygyrus bakeri, consistently alters microbial communities throughout the murine small and large intestine

Alexis Rapin, Luc Xavier Marie Lebon, Nicola Harris, Benjamin John Marsland, Mario Michael Zaiss, Audrey Geneviève Chuat

Increasing evidence suggests that intestinal helminth infection can alter intestinal microbial communities with important impacts on the mammalian host. However, all of the studies to date utilize different techniques to study the microbiome and access dif ...

Immune serum-activated human macrophages coordinate with eosinophils to immobilize Ascaris suum larvae

Nicola Harris, Julia Esser-von Bieren, Beatrice Volpe, Kathleen Shah, Tiffany Babette Angélique Bouchery

Helminth infection represents a major health problem causing approximately 5 million disability-adjusted life years worldwide. Concerns that repeated anti-helminthic treatment may lead to drug resistance render it important that vaccines are developed but ...

WILEY2020

The emerging roles of eosinophils in mucosal homeostasis

Nicola Harris, Kathleen Shah

Eosinophils are granulocytes, typically implicated as end-stage effector cells in type-II immune responses. They are capable of producing a wide array of pre-formed molecules which render them with vast potential to influence a wide variety of processes. N ...

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 ...

House dust mite drives proinflammatory eicosanoid reprogramming and macrophage effector functions

Nicola Harris, Julia Esser-von Bieren, Tiffany Babette Angélique Bouchery

Background Eicosanoid lipid mediators play key roles in type 2 immune responses, for example in allergy and asthma. Macrophages represent major producers of eicosanoids and they are key effector cells of type 2 immunity. We aimed to comprehensively track e ...

Recent Advances in Type-2-Cell-Mediated Immunity: Insights from Helminth Infection

Nicola Harris

Type-2-cell-mediated immune responses play a critical role in mediating both host-resistance and disease-tolerance mechanisms during helminth infections. Recently, type 2 cell responses have emerged as major regulators of tissue repair and metabolic homeos ...

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 ...
