Abstract:
Microglia, the main immune cell of the central nervous system (CNS), categorized into M1-like phenotype and M2-like phenotype, play important roles in phagocytosis, cell migration, antigen presentation, and cytokine production. As a part of CNS, retinal microglial cells (RMC) play an important role in retinal diseases. Diabetic retinopathy (DR) is one of the most common complications of diabetes. Recent studies have demonstrated that DR is not only a microvascular disease but also retinal neurodegeneration. RMC was regarded as a central role in neurodegeneration and neuroinflammation. Therefore, in this review, we will discuss RMC polarization and its possible regulatory factors in early DR, which will provide new targets and insights for early intervention of DR.
Insights
Retinal microglial cells (RMC) polarization is key in early diabetic retinopathy (DR) neuroinflammation. Understanding RMC regulation offers new therapeutic targets for DR intervention.
Area of Science:
- Neuroscience
- Immunology
- Ophthalmology
Background:
- Microglia are the primary immune cells in the central nervous system (CNS).
- Retinal microglial cells (RMC) are crucial in retinal diseases, including diabetic retinopathy (DR).
- DR involves both microvascular damage and neurodegeneration in the retina.
Purpose of the Study:
- To review the polarization of RMC in early DR.
- To explore potential regulatory factors influencing RMC polarization in early DR.
- To identify novel therapeutic targets for early DR intervention.
Main Methods:
- Literature review focusing on RMC polarization and DR.
- Analysis of studies on neuroinflammation and neurodegeneration in early DR.
- Synthesis of information on regulatory factors affecting RMC phenotypes (M1/M2).
Main Results:
- RMC polarization plays a significant role in the neuroinflammatory and neurodegenerative processes of early DR.
- Specific regulatory factors influencing RMC polarization in DR are being identified.
- The M1/M2 phenotypes of RMC are critical in disease progression.
Conclusions:
- RMC polarization is a central mechanism in early diabetic retinopathy.
- Targeting RMC regulatory factors may offer new strategies for early DR treatment.
- Further research into RMC behavior can advance DR management.
