Abstract: Superoxide dismutase (SOD) is a well-known cellular antioxidant enzyme. However, exogenous
SOD cannot be used to protect tissues from oxidative damage due to the low permeability of the
cell membrane. Cell-penetrating peptides (CPPs) are a class of short peptides that can cross the cell
membrane. Recombinant fusion protein that fuses SOD protein with CPP (CPP-SOD) can cross various
tissues and organs as well as the blood-brain barrier.
CPP-SODs can relieve severe oxidative damage in various tissues caused by radiation, ischemia, inflammation,
and chemotherapy by clearing the reactive oxygen species, reducing the expression of
inflammatory factors, and inhibiting NF-κB/MAPK signaling pathways. Therefore, the clinical application
of CPP-SODs provides new therapeutic strategies for a variety of oxidative stress-related disorders,
such as Parkinson’s disease, diabetes, obesity, cardiac fibrosis, and premature aging.
