Hymenolepis nana is the most commonly known intestinal cestode infecting mainly human. This study aimed to investigate the potential effect of chitosan particles (CSP) to enhance the immune system against H. nana infection. Determination of worm burden, egg output, histopathological changes,
The function of cytokines produced during Hymenolepis nana egg infection in mice in protective immunity against re-infection was examined. Treatment of mice with monoclonal antibody (MAb) against mouse interferon (IFN)-gamma caused suppression of protective immunity against H. nana re-infection when
It has emerged that neutrophils can play important roles in the host response following infection with helminth parasites. Mice infected with the tapeworm, Hymenolepis diminuta, are protected from some inflammatory conditions, accompanied by reduced neutrophil tissue infiltration. Thus, the ability
FK-506 (Tacrolimus) has been shown to block T cell proliferation in vitro by inhibiting the generation of several lymphokines, especially interleukin (IL)-2, but little direct evidence is available to support the view that the immunosuppressive effects of FK-506 in vivo are mediated by a similar
Analysis of parasite-host interactions can reveal the intricacies of immunity and identify ways to modulate immunopathological reactions. We assessed the ability of a phosphate-buffered saline-soluble extract of adult Hymenolepis diminuta to suppress macrophage (human THP-1 cell line, murine
Hymenolepis diminuta is a tapeworm that occurs worldwide. It is known to be found commonly in areas where large amounts of food grains or other dry feed products, which are the favorite foods for rats. Transmission of disease to human is uncommon; however, it may be a serious threat for population
Employing an in vitro maintenance system, in which 8-day-old Hymenolepis diminuta survives for 24 hr (Fioravanti and MacInnis, 1976), it was found that farnesol or farnesal supplementation of the medium had no beneficial effects on maintenance and these substances induced necrosis at higher
