Nanoarchitecture of the ventral disc of Giardia intestinalis as revealed by high-resolution scanning electron microscopy and helium ion microscopy
- BiologyHistochemistry and cell biology

Results showed that the disc is a non-uniformly organized structure that presents specific domains, such as the margin and the ventral groove region, and actin-like filaments and microtubules of the disc are associated, showing an interconnection between elements of the cytoskeleton of the trophozoite.

This compound produced morphologic modifications of trophozoites, with occasional loss of one of the nuclei, among other changes not observed with standard giardicidal drugs, suggesting that it might act through a novel mechanism of action.

Furazolidone was more effective than metronidazole and its effects were observed in cells treated with 1 µg/ml (the lowest concentration) as early as 6 h after the start of exposure, showing the cytoplasm depleted of its contents and great changes in volume.

The data suggest that sirtuin activity is important for the proliferation of T. cruzi replicative forms, for the host cell-parasite interplay, and for differentiation among life-cycle stages; but each one performs different roles in most of these processes.

It is proposed that Giardia possess a pathway of autophagy and a form of apoptosis very different from the classical known mechanism; this may represent an early form of programmed cell death.
