These secreted proteins are main topics of research as they are possible vaccine candidates or may have therapeutic potential to treat inflammatory disorders. Many helminth secretory proteins carry complex N-glycans, but the exact role of these N-glycans on immunomodulatory properties remains to be elucidated. As the purification of a single glycoprotein from S. mansoni is inefficient and unsustainable, a platform is required that enables production of such glycoproteins. Here we show that S. mansoni-derived glycoproteins can be efficiently produced in plants. Furthermore, we have engineered the plant glycosylation machinery to synthesise N-glycans carrying structures like Lewis X or LDNF. Altogether, our results demonstrate that plants are an excellent platform for the expression of helminth glycoproteins with their native N-glycans. This opens up a new field of research and might lead to the identification of novel therapeutic targets.
