TPI1 and schistosomiasis: Monoclonal, recombinant antibodies or peptides against transcription factors could be an option, because it is known that polyclonal and monoclonal antibodies against non-conserved regions inhibit in ~74% the catalytic activity of T. solium triosephospate isomerase (TPI), and monoclonal against to S. mansoni TPI by passive immunization assays confer partial protection (41–49%) against schistosomiasis in mice [49–51].
