Title: COVID-19: anti-infectious and anti-inflammatory action of immunomodulatory parasite molecules in a safe-to-use synthetic format

Research groups: Viral Biology and Virus Experimental Evolution

The group of Dr. Mar Siles Lucas at IRNASA handles in vitro and in vivo models of parasitic-host interactions with Fasciola hepatica, which could be used to evaluate the potential of the parasite and its molecules to modulate relevant entry routes and inflammation routes in COVID-19. On one hand, this parasite has shown influence on the expression of endocytosis-related molecules (e.g. clathrins) on in vitro mouse epithelial cells, routes that may be relevant for SARS-Cov-2 entry to human cells. In addition, F. hepatica results in a modified Th2 response without the inflammatory component in its host in vivo, and this modulation may result in a controlled inflammatory response to COVID-19.
