Eliminating Schistosomes through Vaccination: What are the Best Immune Weapons?

Abstract: The successful development of vaccines depends on the knowledge of the immunological mechanisms associated with the elimination of the pathogen. In the case of schistosomes, its complex life cycle and the mechanisms developed to evade host immune system, turns the development of a vaccine against the disease into a very difficult task. Identifying the immunological effector mechanisms involved in parasite attrition and the major targets for its response is a key step to formulate an effective vaccine. Recent s… Show more

“…The mainstay for the control of schistosomiasis is mass drug administration (MDA) of praziquantel (PZQ) through MDA control programs (Gryseels et al 2006). However, the outcomes of these control programs have been largely suboptimal due to insufficient coverage and lack of sustained reduction in the prevalence and transmission of the disease (El Ridi et al 2015; Fonseca et al 2015). Coverage data indicate that less than satisfactory numbers of schistosomiasis-affected people are being treated with PZQ, highlighting the shortcomings of the current control program (Hotez 2009; Ricciardi et al 2016).…”

“…Atualmente, três antígenos se encontram em fases de testes clínicos, a glutationa-Stransferase de 28 kDa de S. haematobium (Sh28GST), a tetraspanina-2 de Schistosoma mansoni (SmTSP-2) e a proteína ligante de ácidos-graxos de 14 kDa de S. mansoni (Sm14) (FONSECA et al, 2015).…”

“…A Sh28GST é uma enzima expressa no tegumento de esquistossômulos e vermes adultos que vem sendo exaustivamente estudada como antígeno contra a esquistossomose experimental e se mostrou capaz de reduzir a carga parasitária e/ou a fecundidade dos parasitas em roedores (DUPRE et al, 1999), macacos e gado (GRZYCH et al, 1998), sendo esta capacidade atribuída a produção de anticorpos que bloqueiam a atividade GST (BOURKE et al, 2014;FONSECA et al, 2015;RIVEAU et al, 2012 Já a Sm14 é uma proteína expressa em todos os estágios do parasita, localizada no tegumento e epitélio do intestino, possivelmente relacionada à absorção de lipídios do hospedeiro pelo parasita para a manutenção do sistema complexo de membranas e das funções fisiológicas (BRITO et al, 2002). Além da completa proteção observada em camundongos contra a infecção por S. mansoni, a imunização com rSm14 também protege os animais contra a infecção por Fasciola hepatica mostrando o potencial do uso desta vacina contra ambos os helmintos (TENDLER et al, 1996).…”
