Unexpectedly, WT animals displayed higher values of parasitemia trough the first stage of infection until 7 dpi, indicating that, although in experiments with isolated peritoneal cells from Beclin-1 KD mice showed an increased infection compared to WT, some delay is produced perhaps in the exit of parasites from the cells in the first infective cycle, or alternatively, in the transit required to reach the bloodstream in KD animals. Here, BECN1 is linked to parasitic infectious disease.
