Lysosomal enzyme activities

Donor age has no effect on lysosomal enzyme activities in human cells.

“These impairments culminate into incomplete elimination of damaged mitochondria, despite preserved activity of the lysosomal enzymes assessed.”

Age is associated with lysosomal enzyme activities in rats.

“opposite patterns of change were often observed in the activities in parenchymal cells and in nonparenchymal cells.”
