Neurocysticercosis (NCC) is a disease caused by the presence of cysticerci (larvae) of Taenia solium in the brain due to the ingestion of eggs of this parasitic helminth (García et al., 2020). NCC causes neurological symptoms such as epilepsy and even death (Son et al., 2019). Cysticerci can remain viable for several months or years without producing inflammation or symptoms (Gutierrez-Loli et al., 2017). It has not been possible to explain what allows the viable larva of T. solium to evade the immune response of its host. T. solium releases helminth-derived-products (HDP), including RNA and protein, through extracellular vesicles (EVs) (Zakeri et al., 2018). HDPs include microRNAs (miRNAs), very short regulatory RNAs with a conserved role in post-transcriptional regulation of eukaryotes (Paul et al., 2020). Its presence in the EVs of T. solium suggests a regulatory role on the host. A target prediction analysis of miR-10-5p and let-7-5p, the most abundant miRNAs identified in the cysticerci of T. solium, showed that they are associated with mammalian immunoregulatory pathways (Landa et al., 2019). This and other studies on miRNAs in 2 parasitic helminths support interspecific RNA transfer as a control of the host immune response. For this reason, it is suggested that the miRNAs secreted by the viable cysticercus of T. solium housed in the brain could modulate the host's immune response. This study proposes (1) to identify miRNAs present in EVs derived from T. solium; (2) carry out in vitro tests to check the effect of EVs on microglia, typical of the central nervous system, and other immune cells; (3) compare miRNA sequences with transcriptomic data from human brain cell lines to find possible target molecules and (4) evaluate in vivo immunoregulation of candidate miRNAs using pigs, the natural host of T. solium.
