Oxidative Stress and Neuroinflammation Potentiate Each Other to Promote Progression of Dopamine Neurodegeneration

الملخص EN

Parkinson’s disease (PD) is a chronic and complex disease of the central nervous system (CNS).

Progressive loss of dopamine (DA) neurons in midbrain substantia nigra is considered to be the main cause of PD.

The hallmark of PD pathology is the formation of Lewy bodies and the deposition of α-synuclein (α-syn).

The mechanisms responsible for the progressive feature of DA neurodegeneration are not fully illustrated.

Recently, oxidative stress and neuroinflammation have received extensive attention as two important entry points in the pathogenesis of PD.

The occurrence of oxidative stress and neuroinflammation is usually derived from external influences or changes in internal environment, such as the accumulation of reactive oxygen species, exposure to a toxic environment, and the transformation of systemic inflammation.

However, PD never results from a single independent factor and the simultaneous participation of oxidative stress and neuroinflammation contributed to PD development.

Oxidative stress and neuroinflammation could potentiate each other to promote progression of PD.

In this review, we briefly summarized the conditions of oxidative stress and neuroinflammation and the crosstalk between oxidative stress and neuroinflammation on the development of PD.
