Advanced glycation end-products and advanced oxidation protein products in schizophrenia

Schizophrenia pathophysiology is still not well understood. Genetic factors involving biochemical systems are key players and oxidative stress takes part to the development and worsening of SZ. Oxidative stress led to the permanent production of oxidation products such as advanced glycation end products (AGEs) and advanced oxidation protein products (AOPPs). These proteins interact with their receptor amplifying ROS production and pro-inflammatory cytokines sustaining a permanent loop. We tested plasma levels of AGEs and AOPPs in 30 SZ patients. Their levels were statistically higher than controls confirming their involvement in mental disorders. Antioxidant nutraceuticals and a healthy lifestyle could diminish oxidative stress and ameliorate SZ symptoms.

Automated summary

The pathophysiology of schizophrenia is still not well understood. Genetic factors and oxidative stress play key roles in its development and progression. Oxidative stress leads to the continuous production of oxidation products, such as AGEs and AOPPs, which interact with their receptors, amplifying the production of reactive oxygen species (ROS) and pro-inflammatory cytokines. In this study, plasma levels of AGEs and AOPPs were found to be significantly higher in schizophrenia patients compared to controls, confirming their involvement in mental disorders. Antioxidant nutraceuticals and a healthy lifestyle could reduce oxidative stress and alleviate schizophrenia symptoms.
