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

Cell Reports, 2016
Summary: 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

Comparison Between Phenotypic Profile and Functional Aspects of IL‐9‐Producing Lymphocytes, Th17 and Tfh of Individuals From Endemic and Non‐Endemic Areas for Hookworm Infection

Parasite Immunology, Volume 48, Issue 3, March 2026.
ABSTRACT Hookworm infections remain a major public health concern in endemic areas, modulating both the adaptive and innate immune systems. While the type 2 response is well‐characterised, the roles of T follicular helper (Tfh), Th17, and IL‐9‐producing lymphocytes remain poorly defined.

Helminth driven gut inflammation and microbial translocation associate with altered vaccine responses in rural Uganda

npj Vaccines
Vaccine responses are sometimes impaired in rural, low-income settings. Helminth-associated gut barrier dysfunction and microbial translocation (MT) may be implicated. We used samples from a trial of praziquantel treatment-effects on vaccine responses in

Immunogenicity to the bivalent HPV-16/18 vaccine among adolescent African students exposed to helminths and malaria

Journal of Infection in Developing Countries, 2015
Introduction: Efficacious vaccines that prevent human papillomavirus (HPV) infection, the recognized cause of cervical cancer, are now available. However, in sub-Saharan Africa, immune-modulating infections such as helminths and malaria may affect ...

The parasitic helminth product ES-62 suppresses pathogenesis in collagen-induced arthritis by targeting the interleukin-17–producing cellular network at multiple sites [PDF]

, 2012
Among many survival strategies, parasitic worms secrete molecules to modulate host immune responses. One such product, ES-62, is protective in the collagen-induced arthritis (CIA) model of rheumatoid arthritis.

Distinguishing Features of ILC2s During Type 2 Immune Responses

European Journal of Immunology, Volume 56, Issue 2, February 2026.
Group 2 innate lymphoid cells (ILC2s) are tissue‐resident cells regulated by diverse signals often emanating from surrounding nonhematopoietic cells at barrier surfaces. Their effector cytokines determine tissue homeostasis at steady state and during type 2 immunity in allergies or worm infections.

Exploring the immunology of parasitism--from surface antigens to the hygiene hypothesis [PDF]

, 2009
Helminth immunology is a field which has changed beyond recognition in the past 30 years, transformed not only by new technologies from cDNA cloning to flow cytometry, but also conceptually as our definition of host immune pathways has matured.
