Changes in the amount of matrix metalloproteinases and kynurenines in individuals with diabetic retinopathy, their role in the development of the disease
Observational analysis reveals altered matrix metalloproteinases and kynurenines in diabetic retinopathy patients, indicating their potential role in disease severity.
Key Points
Significant increases in MMP-2 and MMP-9 levels were observed in patients with diabetic retinopathy compared to healthy individuals.
Patients with proliferative diabetic retinopathy had higher concentrations of MMP-9 and MMP-2 than those with non-proliferative stages.
Kynurenines showed a marked increase with the progression of diabetic retinopathy, particularly in later stages.
The study suggests that monitoring MMPs and kynurenines may help assess the severity of diabetic retinopathy in patients.
