Abstract:
Retinal inflammation underlies multiple prevalent retinal diseases. While microglia are one of the most studied cell types regarding retinal inflammation, growing evidence shows that Müller glia play critical roles in the regulation of retinal inflammation. Müller glia express various receptors for cytokines and release cytokines to regulate inflammation. Müller glia are part of the blood-retinal barrier and interact with microglia in the inflammatory responses. The unique metabolic features of Müller glia in the retina makes them vital for retinal homeostasis maintenance, regulating retinal inflammation by lipid metabolism, purine metabolism, iron metabolism, trophic factors, and antioxidants. miRNAs in Müller glia regulate inflammatory responses via different mechanisms and potentially regulate retinal regeneration. Novel therapies are explored targeting Müller glia for inflammatory retinal diseases treatment. Here we review new findings regarding the roles of Müller glia in retinal inflammation and discuss the related novel therapies for retinal diseases.

Purpose of the Study:
- To review recent findings on Müller glia's roles in retinal inflammation.
- To discuss novel therapeutic strategies targeting Müller glia for inflammatory retinal diseases.
Main Methods:
- Review of current literature on Müller glia function in retinal inflammation.
- Analysis of Müller glia's interactions with cytokines and microglia.
- Examination of Müller glia's metabolic and miRNA-mediated regulatory mechanisms.
Main Results:
- Müller glia express cytokine receptors and release cytokines, modulating inflammation.
- They contribute to the blood-retinal barrier and interact with microglia.
- Unique metabolic activities (lipid, purine, iron metabolism) and trophic factors are vital for retinal homeostasis and inflammation control.
- miRNAs within Müller glia regulate inflammatory responses and potentially retinal regeneration.
Conclusions:
