Mast cells in gastrointestinal helminth infection
Helper T cells type 2 (Th2)play an essential role in host protective responses against the gastrointestinal (GI) nematode parasite, Trichinella spiralis. It is believed that mast cell recruitment and activation may be associated with parasite expulsion from mice. In the current study, we …

Influence of helminth infection on vaginal immunity
Helminth infections induce systemic changes to host immunity and can impact unrelated infections, even those occurring at anatomical sites not normally colonised by the helminths. A few studies have shown that helminths can increase the risk of infection and pathology resulting from sexually …

Characterisation of an immune-modulating peptide secreted by a helminth worm
Parasitic worms (helminths) have evolved mechanisms to potently modulate the mammalian immune response to ensure their long-term survival, while concomitantly preventing excessive tissue pathology within the host. The outcome of this activity is a potent suppression of mammalian pro-inflammatory …

Helminth, protozoan and viral infections of the European eel, Anguilla anguilla
The European eel, Anguilla anguilla, is an important catadromous fish that has beenclassified as critically endangered due to severe population decline. The reasons for this arenot fully understood; however, infectious disease undoubtedly makes a contribution. To explorethis further, a total of 509 …

Modulation of macrophage metabolism and function by the helminth peptide FhHDM-1
Parasitic worms have evolved sophisticated strategies to regulate their host’s immune response, to prevent expulsion and establish chronic infections. Understanding how they achieve this offers a therapeutic strategy for the treatment of human diseases which are caused by unregulated inflammation. …

Helminth infections of the European eel Anguilla Anguilla in the United Kingdom
… status determined for the different classes of helminth using a combination of morphological and molecular approaches, including a PCR-based restriction digestion approach to discriminate between the gill monogeneans Pseudodactylogyrus anguillae and P. bini. Overall, 101 eels (72.1 %) were …

Regulation of HPV infection and cervical cancer development following a helminth infection
Soil-transmi,ed helminth (STH) infec7ons elicit systemic immune responses and have the ability to alter suscep7bility to other infec7ons in sites uncolonized by the STH. Recent work published by our group demonstrated that hookworm infec7on increased pathology in the female genital tract (FGT) …

Protozoan, helminth and arthropod parasites of the gray squirrel in southwestern Virginia
… for blood parasites; 175 were examined for helminths and 106 for ectoparasitlc arthropods. The incidence of coccidiosis was 91% in which five species were described and identified with the genus, Eimerla. The sporozoan, Hepatozoon griseiscuri Clark. 1958, occurred In the blood as evidenced …

Modulation of macrophage function and immune response by a helminth-derived cysteine protease
Helminth-derived excretory/secretory (ES) products have been demonstrated to mediate the anti-inflammatory/regulatory environment associated with helminth infection (for a review see Allen et al. 2011). The ES products of helminths have been exploited for therapeutic benefit in both murine and …

The immunomodulatory properties of helminth-derived products on dendritic cell maturation and function
… diseases. Using products derived from the helminth parasites Fasciola hepatica and Ascaris lumbricoides we investigated the mechanism by which these responses are induced. Dendritic cells (DC’s) play a crucial role in linking the innate to adaptive arms of the immune system and directing …

Survey of the Helminth Parasites Infecting the Alabama Waterdog <em>Necturus alabamensis</em>.
… but did indicate a difference for nematodes. Helminth populations appear to be overdispersed (the majority of the parasites are found in only a few hosts). This study provides insight into some aspects of the ecological relationships of <em>N. alabamensis</em> and its helminths. However, …

The role of platelets in the pathogenesis of and immunity to helminth infections
… Little is known on the role of platelets in helminth infections, despite our understanding that many helminth species cause significant vascular pathology as they transfer from the circulatory system to diverse tissues as part of their life cycles. Based on previous studies showing tight …

The role of Surfacant Protein D in the control of human helminth infections
… we determined whether individuals exposed to helminths have altered serum SP-D in comparison to unexposed individuals, through analysis (ELISA and Western Blot) of bio banked samples in 2 clinical cohorts from South Africa. Secondly, we aimed to identify if SP-D influences the magnitude of …

The role of interleukin-4 receptor alpha on smooth muscle cells during helminth infection
Interleukin-4 receptor alpha (IL-4Ra) signaling, mediated by the ligands IL-4 and IL- 13, is important for effective host protection during murine Nippostrongylus brasiliensis (N. brasiliensis) and Schistosoma mansoni (S. manson!) infection. Among other cell types, IL-4Ra responsive smooth muscle …

The role of Cysteinyl leukotriene receptor-1 during experimental helminth infections in murine model
… is crucial for conferring protective immunity to helminth (Schistosoma mansoni and Nippostrongylus brasiliensis) infection in mice. The role played by cysLTs in the development of protective immune responses to helminth infections is not well documented. Hence in the present study, we investigated …
