What is the Origin of Quinolinic Acid?

The term is biochemical, derived from its parent molecule, kynurenine, and its distinct chemical structure featuring a quinoline ring. It is a product of the fundamental tryptophan metabolic pathway, which links dietary intake to neurochemical signaling. Its classification as a neurotoxin highlights the critical interdependency between systemic inflammation and brain health.

What is the Mechanism of Quinolinic Acid?

QUIN exerts its pathological effects primarily by acting as a powerful agonist at the N-methyl-D-aspartate (NMDA) receptor, a crucial ionotropic receptor for the excitatory neurotransmitter glutamate. Overstimulation of the NMDA receptor by excessive QUIN leads to an uncontrolled influx of calcium ions into the neuron. This calcium overload triggers a cascade of intracellular events that culminate in excitotoxicity, oxidative stress, and subsequent programmed neuronal cell death.

Quinolinic Acid

Meaning

Quinolinic acid (QUIN) is a neuroactive and potentially neurotoxic metabolite generated within the kynurenine pathway of tryptophan catabolism, serving as an endogenous excitotoxin in the central nervous system. Its synthesis is significantly upregulated by chronic immune activation and inflammatory processes, primarily by activated microglial cells and macrophages. Elevated cerebral concentrations of QUIN are implicated in the pathogenesis of various neurodegenerative and psychiatric disorders due to its destructive effects on neuronal tissue.
