Enteric helminth-induced type I interferon signaling protects against pulmonary virus infection through interaction with the microbiota

Nicola Harris, Benjamin John Marsland, Eva Sabrina Gollwitzer

BACKGROUND: Helminth parasites have been reported to have beneficial immunomodulatory effects in patients with allergic and autoimmune conditions and detrimental consequences in patients with tuberculosis and some viral infections. Their role in coinfectio ...

Microbiota Analysis Using an Illumina MiSeq Platform to Sequence 16S rRNA Genes

Alexis Rapin, Céline Pattaroni, Nicola Harris, Benjamin John Marsland

The microbiota have been shown to play an important role in diverse biological processes including immunity, metabolism, and digestion. Assessing the exact composition of the microbiota has proven challenging due to the often unknown growth specificities o ...

Only Two Can Tango: Mast Cells Displace Epithelial Cells to Dance with ILC2s

Nicola Harris, Tiffany Babette Angélique Bouchery

Mast cells have been implicated in protective immunity to helminth infection, but the precise mechanism remains unclear. In this issue of Immunity, Shimokawa et al., 2017 report that mast cells are a bridge linking dying epithelial cells with effector type ...

Neuronal regulation of type 2 innate lymphoid cells via neuromedin U

Nicola Harris, Tania Carvalho, Kathleen Shah, Tiffany Babette Angélique Bouchery

Group 2 innate lymphoid cells (ILC2s) regulate inflammation, tissue repair and metabolic homeostasis1, and are activated by host-derived cytokines and alarmins1. Discrete subsets of immune cells integrate nervous system cues2, 3, 4, but it remains unclear ...

NMR spectroscopy of single sub-nL ova with inductive ultra-compact single-chip probes

Giovanni Boero, Franck Vincent, Nicola Harris, Beatrice Volpe, Marco Grisi

Nuclear magnetic resonance (NMR) spectroscopy enables non-invasive chemical studies of intact living matter. However, the use of NMR at the volume scale typical of microorganisms is hindered by sensitivity limitations, and experiments on single intact orga ...

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 ...

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 ...

Intimate gut interactions: helminths and the microbiota

Nicola Harris

Changing exposure to intestinal helminths, or alterations in our intestinal microbiome, have been independently proposed to underlie the increasing incidence of chronic inflammatory diseases including allergy, autoimmunity and inflammatory bowel disease (I ...

Immune Antibodies and Helminth Products Drive CXCR2-Dependent Macrophage-Myofibroblast Crosstalk to Promote Intestinal Repair

Jérôme Bürgi, Nicola Harris, Benjamin John Marsland, Julia Esser-von Bieren, Beatrice Volpe, Duncan-Bruce Sutherland

Helminth parasites can cause considerable damage when migrating through host tissues, thus making rapid tissue repair imperative to prevent bleeding and bacterial dissemination particularly during enteric infection. However, how protective type 2 responses ...

Antibody-Mediated Trapping of Helminth Larvae Requires CD11b and Fc gamma Receptor I

Manuel Kulagin, Arne Seitz, Nicola Harris, Benjamin John Marsland, Julia Esser-von Bieren, Romain Guiet, Beatrice Volpe, Duncan-Bruce Sutherland

Infections with intestinal helminths severely impact on human and veterinary health, particularly through the damage that these large parasites inflict when migrating through host tissues. Host immunity often targets the motility of tissue-migrating helmin ...

IMMUNOLOGY Chronic effects of acute infections

Nicola Harris

Acute infection of mice with an intestinal pathogen leads to long-lasting inflammation that is maintained by intestinal microorganisms. This observation reveals a path by which infection history can affect long-term immune function. ...

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 ...

Concerted Activity of IgG1 Antibodies and IL-4/IL-25-Dependent Effector Cells Trap Helminth Larvae in the Tissues following Vaccination with Defined Secreted Antigens, Providing Sterile Immunity to Challenge Infection

Nicola Harris, Julia Esser-von Bieren

Over 25% of the world's population are infected with helminth parasites, the majority of which colonise the gastrointestinal tract. However, no vaccine is yet available for human use, and mechanisms of protective immunity remain unclear. In the mouse model ...

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 ...

Cell-wall deficient L. monocytogenes L-forms feature abrogated pathogenicity

Nicola Harris

Stable L-forms are cell wall-deficient bacteria which are able to multiply and propagate indefinitely, despite the absence of a rigid peptidoglycan cell wall. We investigated whether L-forms of the intracellular pathogen L. monocytogenes possibly retain pa ...

Understanding the role of antibodies in murine infections with Heligmosomoides (polygyrus) bakeri: 35 years ago, now and 35 years ahead

Nicola Harris

The rodent intestinal nematode H.p.bakeri has played an important role in the exploration of the host–parasite relationship of chronic nematode infections for over six decades, since the parasite was first isolated in the 1950s by Ehrenford. It soon became ...
