Infection with Schistosoma mansoni prevents insulin dependent diabetes mellitus in non‐obese diabetic mice Tập 21 Số 4 - Trang 169-176 - 1999

The spontaneous development of insulin dependent diabetes mellitus in non‐obese diabetic (NOD) mice has been shown to be mediated by a Th1 response against beta cell antigens. It is known that in murine models of Schistosoma mansoni infection, egg production is associated with a switch from a Th1 to Th2 response. This subsequent dominance of a Th2 r...... hiện toàn bộ Immunology of canine leishmaniasis Tập 28 Số 7 - Trang 329-337 - 2006

SUMMARY The role of dogs as the main reservoir of visceral leishmaniasis has led to an increased interest in the immune responses and in Leishmania antigens implicated in protective cellular immunity in canine visceral leishmaniasis. The primary goal is to control the prevalence of human disease. Immune responses in canine vi...... hiện toàn bộ Cryptosporidium in humans and animals—a one health approach to prophylaxis Tập 38 Số 9 - Trang 535-547 - 2016

SummaryCryptosporidium is a major cause of moderate‐to‐severe diarrhoea in humans worldwide, second only to rotavirus. Due to the wide host range and environmental persistence of this parasite, cryptosporidiosis can be zoonotic and associated with foodborne and waterborne outbreaks. Currently, 31 species are recognized as valid, and of th...... hiện toàn bộ Immunization against malaria with a recombinant protein Tập 16 Số 2 - Trang 63-67 - 1994

SUMMARYWe have expressed in bacteria the C‐terminal part of Plasmodium yoelii merozoite surface protein‐1 (MSP1) containing the two epidermal growth factor‐like domains. The protein, either alone or fused to glutathione Stransferase, was highly effective as a vaccine and protected mice against challenge infection. Reduction and alkylation...... hiện toàn bộ Immunization of mice and baboons with the recombinant Sm28GST affects both worm viability and fecundity after experimental infection with Schistosoma mansoni Tập 13 Số 5 - Trang 473-490 - 1991

Summary A member of the glutathione S‐transferase family. Sm28GST has previous! demonstrated a good ability to protect rodents against experimental infection with Schistosoma mansoni. In order lo evaluate its efficacy in a model closer to man, two different protocols of immunization with recombinant Sm28GST were tested on baboons in a larg...... hiện toàn bộ TNF‐α, nitric oxide and IFN‐γ are all critical for development of necrosis in the small intestine and early mortality in genetically susceptible mice infected perorally with Toxoplasma gondii Tập 21 Số 7 - Trang 365-376 - 1999

We previously reported that genetic susceptibility of mice to peroral infection with T. gondii is associated with CD4+ T cell‐dependent, interferon (IFN)‐γ‐mediated necrosis of their small intestine. We examined the role of tumour necrosis factor (TNF)‐α and nitric oxide (NO), in addition to IFN‐γ. At 7 days after infection, a m...... hiện toàn bộ Immunoregulation in human lymphatic filariasis: the role of interleukin 10 Tập 17 Số 8 - Trang 385-392 - 1995
Siddhartha Mahanty, Thomas B. Nutman
SummaryIn humans with lymphatic filariasis microfilaremia is associated with a parasite antigen‐specific hyporesponsive‐ness when assessed by cell proliferation and secretion of interleukin‐2 and interferon‐γ. Hyporesponsiveness in these individuals is not only parasite antigen‐specific but appears to be limited to Th1‐type responses. Th2 mediated responses such as...... hiện toàn bộ Demonstration of Leishmania specific cell mediated and humoral immunity in asymptomatic dogs Tập 14 Số 5 - Trang 531-539 - 1992
Maria Améllia Lopes Cabral, J. E. O'GRADY, James Alexander
Summary An ELISA and a lymphocyte proliferation assay were used for the detection of anti‐Leishmania antibodies and parasite specific cellular immunity respectively in a preliminary study of canine leishmaniasis in Oporto, Portugal. A high rate of infection was found considering the comparatively small group sampled. Of 34 dogs examined two...... hiện toàn bộ
