Primary Neurotransmitter in ALS Excitotoxicity

Glutamate is the primary excitatory neurotransmitter responsible for the excitotoxicity driving motor neuron decay in Amyotrophic Lateral Sclerosis (ALS).

Mechanisms of Glutamate Pathology

Excessive Accumulation: There is a pathological build-up of extracellular glutamate within the central nervous system, largely driven by defective reuptake mechanisms involving the EAAT2 (GLT-1) transporter on astrocytes.
Overactivation of Receptors: Chronically elevated glutamate overstimulates postsynaptic receptors, particularly NMDA and AMPA receptors.
Calcium Influx: This overstimulation leads to a massive, toxic influx of calcium ions ($Ca^{2+}$) into motor neurons.

Downstream Cellular Consequences

Enzymatic Destruction: Intracellular calcium overload hyperactivates destructive enzymes, including proteases, lipases, and endonucleases, which dismantle vital cellular structures.
Oxidative Stress: The surge in calcium generates high levels of reactive oxygen species (ROS) and free radicals, resulting in severe oxidative damage to lipids, proteins, and DNA.
Mitochondrial Failure: Energy-producing mitochondria become severely impaired and overloaded, triggering apoptotic pathways and programmed cell death.
