After three months, we saw recovery - cristae numbers back toward normal levels, and increases in several molecular indicators involved in new mitochondria production," he said.
Goblet cells: in non-parasitized larvae, the mitochondria are concentrated inside the microvilli, present in the basolateral region of the goblet cell cavity, where the mitochondria have highly electron-dense matrix and many cristae, as much in goblet cells of the anterior region as in the posterior midgut region (Figures 2a-b).
In parasitized larvae, the mitochondria are more abundant (Figure 3b) presenting discrete matrix rarefaction (Figure 3c), and reducing the quantity of cristae and mitochondrial vacuolisation in those of the anterior midgut region (Figure 3c), but do not show alteration in the posterior region (Figure 3d).
39,40] This is probably the result of a combination of age-related changes in the hair cells at the center of the cristae, [34] a relatively selective loss of large-diameter primary vestibular afferents, and neuronal loss in the superior vestibular nuclei.
