With age, GSH levels decrease by up to 50% compared to young subjects, contributing to increased oxidative stress and chronic low-grade inflammation (inflammaging). In the anti-ageing field, GSH IV acts on three main levels: direct neutralisation of free radicals and protection of dermal collagen, modulation of inflammation through NF-B inhibition, and reduction of melanogenesis through tyrosinase inhibition with clinically observable effects on skin tone and luminosity. The most robust clinical evidence concerns neuroprotection (improvement of motor symptoms in Parkinson's disease) and protection from chemotherapy-induced neuropathy
This decline is closely correlated with the loss of tissue regenerative capacity, increased inflammation, and accelerated skin aging
Lets say that your target protein is smaller than GST, such that most of the size of the GST-fusion protein will be contributed from GST and not your target protein
The extrinsic pathway is mediated by binding of death-inducing ligands such as TNF and Fas ligand that bind to cognate receptors that, in turn, recruit adaptor proteins and pro-caspases, leading to the assembly of the death-inducing signaling complex (DISC) and the activation of effector caspases 75
