Mechanisms of action of N-acetylcysteine (NAC).
Increased activity of cystine–glutamate antiporter results in increased activation of metabotropic glutamate receptors on inhibitory neurons and facilitates vesicular dopamine release;
NAC is associated with reduced levels of inflammatory cytokines and acts as a substrate for glutathione synthesis.
These actions are believed to converge upon mechanisms promoting cell survival and growth factor synthesis, leading to increased neurite sprouting.
BDNF = brain-derived neurotrophic factor;
IL = interleukin;
NADP = nicotinamide adenine dinucleotide phosphate;
NADPH = reduced form of NADP;
TNF = tumour necrosis factor.
