Antioxidant activity in neural tissue

Antioxidant activity in neural tissue encompasses the collective action of multiple enzymes (e.g., superoxide dismutase, catalase, glutathione peroxidase, peroxiredoxins, metallothioneins) and small molecules (such as glutathione, vitamins C and E) to neutralize reactive oxygen species (ROS) and maintain redox balance[1][3][6]. Dysfunction of these antioxidant defenses is implicated in a range of neurological diseases, including neurodegeneration and multiple sclerosis, with specific enzymes highly expressed in microglia, astrocytes, and neurons[1][3]. Therapeutically, drugs and dietary antioxidants aim to bolster these endogenous systems, but "antioxidant activity" itself is not a single druggable target or molecular entity[6]. Clarification: The query refers to a **functional property or system**, not a distinct molecular or protein target. For structured profiling, individual components such as "superoxide dismutase" or "glutathione peroxidase" should be specified instead of the general concept of antioxidant activity.
