UFSP1 and infection: Results showed that deletion of Ufsp leads to reduced parasite growth and by 10 weeks post infection, parasite burdens reached to non-detectable levels in LdUfsp−/− infected liver and spleens (Fig. 8C and D) whereas in the mutants parasites in which Ufsp is added back (Ufsp−/−+UfspWT) the parasite growth reached comparable levels to that of wild type parasites.
