Atorvastatin Alleviates Age-Related Macular Degeneration via AIM2-Regulated Pyroptosis.

Inflammation

October 2024

Chongqing Key Laboratory for the Prevention and Treatment of Major Blinding Eye Diseases, Chongqing Eye Institute, The First Affiliated Hospital of Chongqing Medical University, Chongqing Branch of National Clinical Research Center for Ocular Diseases, Chongqing, 400016, China.

The underlying causes of age-related macular degeneration (AMD) remain elusive and treatment options of it are limited, while atorvastatin (AT) is expected to improve AMD. Our study sought to uncover the specific mechanisms that initiate pyroptosis in AMD and elucidate whether AT ameliorates Aβ1-40-induced retinal damage by inhibiting pyroptosis. An animal model of AMD was triggered by Aβ1-40, and the therapeutic efficacy of AT was evaluated by hematoxylin and eosin staining (H&E), Optical Coherence Tomography (OCT), Electroretinogram (ERG) and other methods.

Department of Ophthalmology, Joint Research Laboratory for Ocular Immunology and Retinal Injury Repair, The First Affiliated Hospital of Zhengzhou University, Henan International, Henan Province Eye Hospital, Zhengzhou, P.R. China.

Article Synopsis
  • Irisin is a special hormone made when we exercise, and scientists studied its levels in the eyes of people with certain eye diseases called uveitis.
  • They found that people with these diseases had lower levels of irisin, and more irisin seemed to help reduce the inflammation and bad effects of the disease in experiments with mice.
  • The research also showed that irisin help balance some immune cells in the body and can affect a pathway in the retina that makes the inflammation worse.

Article Synopsis
  • The study aimed to analyze the eye changes in patients with chronic Vogt-Koyanagi-Harada disease during the inactive phase and assess links to permanent eye complications using advanced imaging techniques.
  • Researchers compared 69 patients with the disease and 55 healthy individuals, examining vessel density and volume in the retina and choroid, and investigating how these factors correlated with serious complications.
  • Results showed that patients with longer disease durations (over 24 months) had significantly lower vessel density and volume, suggesting that extended disease duration is associated with greater risk of irreversible eye complications.

The First Affiliated Hospital of Chongqing Medical University, Chongqing Key Lab of Ophthalmology, Chongqing Eye Institute, Chongqing Branch of National Clinical Research Center for Ocular Diseases, Chongqing, PR China. Electronic address:

To investigate the effect of plasma-derived exosomal proteins on neutrophil hyperactivation in Behcet's uveitis (BU), we treated neutrophils from healthy controls with plasma-derived exosomes from active BU patients, and determined the level of neutrophil activation by real-time quantitative PCR (RT-qPCR) and cytokine detection assay. The results revealed that exosomes from active BU patients could activate neutrophils as shown by increasing the expression levels of pro-inflammatory cytokines (IL-17 and IL-6), chemokines (IL-8 and MCP-1), and NETs (MPO and ELANE). Label-free quantitative proteomic analysis of plasma-derived exosomes from patients and healthy controls found a remarkably distinct protein profile and identified differentially expressed proteins (DEPs) between the two groups.
