There are also roles for endogenous nitric oxide (NO) and carbon monoxide (CO) in modulating the ACTH response to stress (194)
Senescence-associated -galactosidase (SA--gal) activity was measured in both cells and frozen tissues using a commercial kit, providing a visual and quantitative indicator of senescent cells
immune cells are among the most GSH-dependent in the body Redox signalling the GSH/GSSG (reduced/oxidised) ratio is a master regulator of cellular redox state, modulating transcription factors including NF-B and Nrf2 Protein maintenance glutathionylation protects cysteine residues in proteins from irreversible oxidation, preserving enzyme function Glutathione levels decline with age, chronic illness, toxin exposure, and oxidative stress contributing to accelerated cellular aging, impaired detoxification, and systemic inflammation
Furthermore, at synaptic interfaces, VC potentiates GABAergic inhibition via GABA B1 receptor up-regulation while competitively inhibiting NMDA-mediated calcium influx, a dual mechanism stabilizing excitatory-inhibitory equilibrium [8]
