Summary: The aim of this study was to investigate the influence of dietary supplementation using Age-Related Eye Disease Study 2 (AREDS2) on complement activation in patients with neovascular age-related macular degeneration (nAMD) under ongoing treatment. The results showed that short-term dietary AREDS2 supplementation leads to a significant increase in systemic zinc levels without any influence on complement activation levels.

Summary: Age-related macular degeneration is a global disease with a significant social impact, and the treatment of neovascular AMD has been revolutionized by the advent of anti-VEGF therapy. Currently, investigations are being conducted for possible therapeutic options for dry AMD. Various treatments, including complement pathway inhibitors, visual cycle modulators, antioxidative therapy, gene therapy, and stem cell therapy, are undergoing clinical trials. Two intravitreal anti-complement factors have shown promising results in reducing the growth of geographic atrophy.

Summary: The dysregulation of the alternative complement pathway is a major pathogenic mechanism in age-related macular degeneration. Complement mRNA and protein expression levels were found to be significantly higher in macular retinal pigment epithelium/choroid tissue than in the neural retina, regardless of AMD grade status. The study suggests that the RPE/choroid is the primary site for complement inhibition to treat geographic atrophy or earlier stages of the disease.

Summary: Age related macular degeneration (AMD) and diabetic retinopathy (DR) are neurodegenerative and inflammatory diseases of the eye. Both diseases involve cellular components of the blood-retina barrier (BRB) and share common drivers, such as chronic inflammation. Long pentraxin 3 (PTX3), a soluble pattern recognition molecule, is emerging as a potential therapeutic target in retinal diseases, as it plays a role in trapping complement and modulating inflammation at the BRB.

Summary: This study investigated the association between serum complement components and AMD. The results showed that higher levels of C1q and lower levels of C3 were associated with increased risk of AMD in female patients. This suggests that the complement classical pathway may be involved in the development of AMD, especially in females.

Summary: Age-related macular degeneration (AMD) is a major cause of vision impairment, but currently there is no effective treatment for the majority of patients. Studies have shown that the complement system and remodeling of the extracellular matrix play a significant role in AMD. Excessive activation of the complement system can lead to tissue damage and complement-associated diseases like AMD. The latest findings suggest abnormal activation of the alternative pathway in AMD patients, which has important implications for future clinical trials and treatment prospects.

Summary: The complement system is essential for the body's defense against pathogens, but dysregulation can lead to diseases such as age-related macular degeneration (AMD). Complement activation occurs in various parts of the eye, including the choriocapillaris and the subretinal and retinal pigment epithelium spaces. The barrier of Bruch's membrane impedes complement protein diffusion and its dysfunction contributes to AMD pathogenesis. This review examines the structure of Bruch's membrane, its age-related changes, and the potential of different delivery routes for complement inhibitors in treating AMD.

Summary: The study found differences in the characteristics of choroidal endothelial cells in young and old monkey eyes, with cells in older eyes being stiffer and more susceptible to complement activation-induced damage. These differences may be related to the activities of the mechanical structure regulators Rac and Rho in the cells. These findings offer new mechanistic insights into choroidal vascular loss in early AMD and warrant further investigation for translational potential.

Summary: Circulating cell-free DNA (cf-DNA) levels are associated with age, sex, smoking, physical activity, vegetable consumption, ageing phenotypes, and various biomarkers. Higher cf-DNA levels were found in men, especially middle-aged men and women who smoke, and older frail individuals. Inflammatory markers, metabolites, and antioxidant levels were correlated with cf-DNA levels. These findings have implications for future studies on the epidemiology and biological mechanisms of cf-DNA and its potential as a clinical marker.

Summary: This study tested whether cross-sectional modeling can distinguish slow vs accelerated aging in a human population. A machine learning model was trained to predict age and tested against longitudinal data. The results showed that the cross-sectional proxy failed to predict longitudinal observations, suggesting that differences in starting points may explain diverging aging rates.

Summary: More than 1/4 of children globally lack documentation of their date of birth, emphasizing the need for biological methods to predict age. DNA methylation is the most promising biomarker for age assessment, but there is currently no epigenetic clock specifically designed for adolescents and young adults. A novel age predictor called PAYA, using 267 CpG methylation sites, shows potential for age assessment in this population, but further research is needed to test its robustness across different populations and environments.

Summary: This study used an unsupervised machine learning method called PGMRA to discover the genotype-lipidome relations in a Finnish population. The researchers found 93 statistically significant lipidome-genotype relations, which contained a total of 5977 SNPs across 3164 genes. Twenty nine of these relations represented distinct subgroups with unique SNPs and participants. Pathway enrichment analysis identified 30 significantly enriched biological processes related to plasma lipid metabolism. These findings have implications for precision medicine research.

Summary: This study identifies new genetic variants associated with resting heart rate (RHR) and demonstrates that higher genetically predicted RHR is associated with a decreased risk of atrial fibrillation and ischemic stroke. Genome-wide analysis reveals multiple genetic variants in cardiomyocyte-related genes and provides insights into their electrocardiogram (ECG) signature. Mendelian randomization analyses indicate that higher genetically predicted RHR increases the risk of dilated cardiomyopathy, but reduces the risk of atrial fibrillation, ischemic stroke, and cardio-embolic stroke.
