For that reason, aged PGRN-deficient mice might have an impaired autophagy-lysosomal system. Considering the fact that pinclusions have been observed in neuronal and glial cells, PGRN may well play a role in maintaining lysosomal function in the course of aging in each neuronal and glial cells. Disruption of both the ubiquitin-proteasome program as well as the autophagy-lysosomal program is amongst the characteristic features of FTLD with TDP-43 inclusions within the cytoplasm of neurons [27], and impaired production of PGRN is involved within this pathology [5-7].
