Abstract
The neurodegeneration is one of the features of aging and age-related disorders. Yet, only several antiaging interventions are known to affect the processes of neurodegeneration. Here we show that overexpression of the pro-longevity gene D-GADD45 in Drosophila neurons leads to a postponed manifestation of histological and ultrastructural features of age-dependent neurodegeneration, such as decrease in the packing density of neurons, increasing the degree of neuron cytoplasmic vacuolization, and morphological defects of mitochondrial cristae. Thus, the previously observed (Plyusnina, Biogerontology 12: 211–226, 2011) life extending effect of D-GADD45 overexpression in the nervous system is associated with delayed neurodegeneration.
