Hpb infection suppresses immune responses to bystander antigens and unrelated pathogens, and it slows the progression and modifies the outcome of immune-mediated diseases. Hpb-derived excretory-secretory (ES) products potently modulate CD4(+) helper T cell (TH) responses by inducing regulatory T cells, tolerogenic dendritic cells (DCs) and immunoregulatory cytokines. This observation has spiked interest in identifying the immunomodulatory molecules, especially proteins, in ES products from Hpb and other GI nematodes for development as novel therapies to treat individuals with immune-mediated diseases, such as inflammatory bowel diseases (IBDs). In this protocol, we describe how to (i) maintain Hpb in the laboratory for experimental infections, (ii) collect adult worms from infected mice to generate ES products and (iii) evaluate the modulatory effects of ES products on toll-like receptor (TLR) ligand-induced maturation of CD11c(+) DCs. The three major sections of the PROCEDURE can be used independently, and they require ∼6, 10 and 27 h, respectively. Although other methods use a modified Baermann apparatus to collect Hpb adult worms, we describe a method that involves dissection of adult worms from intestinal tissue. The protocol will be useful to investigators studying the host-parasite interface and identifying and analyzing helminth-derived molecules with therapeutic potential.","is_dataset_classified":null,"base_score":3.713572066704308,"endowment":3.713572066704308,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"25375989","pmcid":null,"openalex_id":"https://openalex.org/W2010756475","authors":[],"funders":[{"funder_name":"Canadian Institutes of Health Research","grant_id":"MOP 81169","title":null},{"funder_name":"Canadian Institutes of Health Research","grant_id":"MOP 94589","title":null},{"funder_name":"Canadian Institutes of Health Research","grant_id":"MOP 130369","title":null},{"funder_name":"Natural Sciences and Engineering Research Council of Canada","grant_id":"unidentified","title":"unidentified"}],"total_grants":4,"fwci":2.0128,"citation_percentile":0.83847512,"influential_citations":0,"citation_trend":[{"year":2016,"count":4},{"year":2017,"count":6},{"year":2018,"count":4},{"year":2019,"count":2},{"year":2020,"count":8},{"year":2022,"count":3},{"year":2023,"count":2},{"year":2024,"count":7},{"year":2025,"count":3},{"year":2026,"count":1}],"oa_status":"closed","license":"Springer TDM","oa_locations":[{"url":"http://www.nature.com/articles/nprot.2014.184.pdf","host_type":"publisher"},{"url":"http://www.nature.com/articles/nprot.2014.184","host_type":"publisher"},{"url":"https://doi.org/10.1038/nprot.2014.184","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/25375989","host_type":"repository"},{"url":"https://pure.qub.ac.uk/en/publications/2eba2f3d-e3f4-4a92-8de8-4fb8d002d4ce","host_type":"repository"},{"url":"https://dx.doi.org/10.1038/nprot.2014.184","host_type":""},{"url":"https://doi.org/https://doi.org/10.1038/nprot.2014.184","host_type":""}],"fields_of_study":["Parasites and Host Interactions","Parasitic Diseases Research and Treatment","Helminth infection and control","0301 basic medicine","0303 health sciences","03 medical and health sciences","Animals","CD11c Antigen","Dendritic Cells","Feces","Female","Host-Parasite Interactions","Immunologic Factors","Intestines","Male","Mice","Mice, Inbred BALB C","Nematospiroides dubius","Strongylida Infections"],"mesh_terms":["Animals","Dendritic Cells","Feces","Female","Host-Parasite Interactions","Immunologic Factors","Intestines","Male","Mice, Inbred BALB C","Nematospiroides dubius","Strongylida Infections","CD11c Antigen","Mice"],"keywords":["Heligmosomoides polygyrus","Excretory system","Nematode","Biology","Microbiology","Ecology","Anatomy","Male","Mice, Inbred BALB C","Nematospiroides dubius","/dk/atira/pure/subjectarea/asjc/1300/1300","610","Dendritic Cells","CD11c Antigen","Host-Parasite Interactions","Intestines","Feces","Mice","name=General Biochemistry,Genetics and Molecular Biology","616","Animals","Immunologic Factors","Female","Strongylida Infections"],"sdg_mappings":[{"sdg_number":2,"sdg_label":"2.
