Anhedonia, a typical symptom of many mental diseases, is also an important indicator for treatment outcome. Further exploration of the mechanism of anhedonia and clear definition and illustration of its pathophysiological basis are helpful to the diagnosis and treatment of related diseases. In recent years, converging evidence has implicated that inflammation-driven alterations in kynurenine pathway (KP) and tetrahydrobiopterin (BH4) metabolism lead to nerve injury and disturbance of neurotransmitter in reward circuit, which is closely related to the emergence and development of anhedonia. Therefore, this review aims to summarize the research advances in the inflammatory mechanism of anhedonia, with the emphasis on both KP and BH4 metabolism.
