Immunity to gastrointestinal nematodes in ruminants: Effector cell mechanisms and cytokines

Open access
Hendawy, Seham H. M.·2018·Journal of Parasitic Diseases

Abstract

Gastrointestinal nematodes (GINs) of ruminants are prevalent and have major economic impacts worldwide. The insight studies of immune responses triggered against GINs are of great concern to understand interaction between host's immune system and parasite. T-helper 2 cytokines drive the effector cell mechanisms which include eosinophils and mast cells. The immune responses are controlled by Th2 secreted interleukins (IL); IL3, IL-4, IL-5, IL-9, IL-10 and IL-13. B-Cell immune response is incorporated in defense mechanisms developed against GINs specially immunoglobulins (Ig); IgA, IgE and IgG. The immune resistance of the infected host is presented by failure of larval establishment or hypobiosis, low worm burden and decreased female fecundity. The host-parasite interaction is a complex series that affected by host's genetic constitution, nutrition, age and physiological status. The GINs have different immune evasion mechanisms to improve their survival within the host. Also, management of the host influences GINs parasitism. Thus, the aim of this review is to highlight the hallmarks of immune responses that endorse GINs parasitism. The insights studies of the triggered immune responses developed against GINs will improve the appropriate protective immune strategy.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Immunomodulatory mediators such as ES-62, cystatins, legumains and cathepsin L and S have an immunomodulatory effect to enhance production of anti-inflammatory IL10.

    “They have an immunomodulatory effect to enhance the production of anti-inflammatory IL10 [17,22].”

    From Emergent and Neglected Equine Filariosis in Egypt: Species Diversity and Host Immune Response (2022) · cites this paper as [17]

    The “Parasitic immune evasion strategies” section says cystatins have an immunomodulatory effect and enhance anti-inflammatory IL10 production. It describes legumains and cathepsins L and S as enzymes inhibited by cystatins, and attributes other immune effects—not IL10 enhancement—to ES-62. The cited passage has no page number in our copy. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • Host-parasite interaction relies on the expressed cytokine profile which is modulated by the parasite itself.

    “Host–parasite interaction relies on the expressed cytokine profile which is modulated by the parasite itself [15,16,17].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
