**Molecular Mechanism and Rationale**
The system xc- transporter, composed of the light chain xCT (SLC7A11) and the heavy chain 4F2hc (SLC3A2), represents a critical component of cellular glutamate homeostasis and oxidative stress response in amyotrophic lateral sclerosis (ALS). This antiporter facilitates the exchange of extracellular cystine for intracellular glutamate in a 1:1 stoichiometry, fundamentally linking cellular antioxidant capacity to excitotoxic vulnerability. In the context of A
## Mechanistic Overview
GPX4 Selenopeptide Mimetics as Neuroprotective Ferroptosis Blockade starts from the claim that modulating GPX4 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## Mechanistic Overview GPX4 Selenopeptide Mimetics as Neuroprotective Ferroptosis Blockade starts from the claim that modulating GPX4 within the disease context of neurodegeneration can redirect a disease-relevant process.
