Their immunomodulation includes polarization to Th2 cell response and promotion of regulatory B lymphocytes (B-regs) and regulatory T lymphocytes (T-regs) [1]. This modulation isn’t just important in order to understand the host-pathogen relationships and to develop treatments against the parasites themselves but also important in the development of treatments against autoimmune and inflammatory diseases. This idea of software of helminth parasites or their subunits for disease treatment has been drawn from your hygiene hypothesis [2]. The hygiene hypothesis was first FLJ16239 proposed by Strachan [3], as he mentioned that there was an inverse correlation between the event of hay fever in children and the number of siblings they had living in the same house. His observation led to the hypothesis that infections in early child years helped to properly develop the rules of the immune system, whereas the lack of such infections would predispose to the emergence of autoimmune diseases [2]. There are several evaluations in the literature regarding the rules of the immune system by helminths [1, 2, 4]. There are also evaluations focused on the part of helminths illness or helminths molecules in controlling sensitive diseases [5, 6] and in host’s rate of metabolism and inflammatory diseases [7C9]. TCS 359 This protecting part not only has been assigned to bias a Th2 immune response but also entails T-regs induction and on the other hand triggered macrophages (AAM), TCS 359 as well as generation of anti-inflammatory cytokines [7, 10C14]. Here, instead of broadening the review with regard to helminths in general, we focus on aspects of the host’s rate of metabolism and immune modulation by schistosome-derived molecules, both in terms of its pathogenesis associated with schistosomiasis and in terms of its interaction with the host’s immune system in the presence of an autoimmune or inflammatory disease. We believe that schistosomes and schistosome-derived molecules can be used like a model to understand the potential applications of helminths against autoimmune and inflammatory diseases. Later on this paper, in its text, and in Table 1 and Number 1, we will present some schistosome-derived molecules whose immunoprotective and anti-inflammatory effects have been shown, as well as other molecules that have the same potential but that still need to be investigated.

Helminthic Therapy of Autoimmune Diseases: The Clinical Tests and the Potential Importance of Schistosomes So far, few clinical tests regarding the use of helminths against autoimmune diseases have been carried out.

We believe that schistosomes and schistosome-derived molecules can be used as a model to understand the potential applications of helminths against autoimmune and inflammatory diseases.

Helminthic Therapy of Autoimmune Diseases: The Clinical Trials and the Potential Importance of Schistosomes So far, few clinical trials regarding the use of helminths against autoimmune diseases have been carried out. According to Fleming and Weinstock [45], up until the date of their publication, 28 clinical trials were being conducted, from planning to completion. All of these were using live parasites, instead of parasite-derived molecules or extracts, and the chosen species wereNecator americanusorTrichuris suisT. suiscauses a zoonotic disease in humans, which is usually self-controlled, and low inoculum doses ofN. americanuslarvae have proven to be well-tolerated by the human host, despite being able to produce 50 eggs per gram of feces [46, 47]. Those trials which had already finished did not show very promising results in the treatment of autoimmune diseases. Evans and Mitre [46] argue that several factors could be involved in these seemingly unfavorable results, such as the apparent ability of helminths to prevent the development of autoimmune diseases, instead of treating them; the location of helminth contamination being incompatible with the desired immunomodulation; the parasitic burden and duration; and the use of concomitant medications and host genetics. Pritchard and colleagues [47] also point out that this absence of heterogeneity of parasitic worm species in the host, during the.
