Antioxidant Signaling

Meaning

Antioxidant signaling describes the intricate cellular communication pathways activated by reactive oxygen species (ROS) or by exogenous and endogenous antioxidants, which collectively regulate cellular defense and repair mechanisms. This biological process is not merely about neutralizing free radicals but involves precise, low-level oxidative stress acting as a vital messenger to fortify the cell. In the context of hormonal health, robust signaling is critical for protecting steroidogenesis and receptor function from oxidative damage. Maintaining this delicate balance is fundamental to overall cellular longevity and metabolic harmony.
