Proliferative retinopathy is a leading cause of irreversible blindness in humans; however, the molecular mechanisms behind the immune cell-mediated retinal angiogenesis remain poorly elucidated. Here, using single-cell RNA sequencing in an oxygen-induced retinopathy (OIR) model, we identified an enrichment of sorting nexin (SNX)-related pathways, with SNX3, a member of the SNX family that is involved in endosomal sorting and trafficking, being significantly upregulated in the myeloid cell subpopulations of OIR retinas. Immunostaining showed that SNX3 expression is markedly increased in the retinal microglia/macrophages of mice with OIR, which is mainly located within and around the neovascular tufts.

Patients with metastatic colorectal cancer (mCRC) to the liver exhibit poor survival rates. Chemotherapy combined with anti-vascular therapy has emerged as the standard treatment, but resistance to anti-VEGFA therapy inevitably develops. The metabolic reprogramming of tumor vascular endothelial cells (TECs) plays a crucial, yet still poorly understood, role in the development of therapeutic resistance.

Objective To determine real-world clinical outcomes (including vision, anatomy and durability) of intravitreal faricimab (IVF) in year two (up to mean follow-up of 75 ± 15 weeks, range: 52-103 weeks) of treating diabetic macular oedema (DMO). Secondary objectives included assessing changes in diabetic retinopathy (DR) severity, the incidence of epiretinal proliferation (ERP)/epiretinal membrane (ERM), and safety. Methodology This is a single-centre retrospective observational study.

Purpose: To report two cases of macular exudations resulting from retinal arterial macroaneurysms (MaAs) refractory to focal photocoagulations that were treated with a new surgical technique including subretinal balanced saline solution (BSS) injection to dilute lipid-rich subretinal fluid (SRF) and facilitate absorption of the SRF, intentional retinal hole formation to direct SRF into the vitreous cavity, and laser photocoagulation posterior to the MaAs to prevent intraretinal fluid and SRF from reaching the fovea.
Observations: A 70-year-old man with macular edema (ME) refractory to anti-vascular endothelial growth factor (VEGF) therapy was referred to our hospital. Fundus examination showed retinal arterial MaAs and hard exudations.

Collecting duct carcinoma (CDC) is a rare but aggressive form of renal cell carcinoma (RCC) that has limited understanding and an undefined systemic therapeutic regimen. Herein, we conducted a comprehensive proteogenomic analysis of CDC tumors and normal adjacent tissues to elucidate the biology of the disease. CDC exhibited high heterogeneity in tumor mutational burden, and enhanced ribosome biogenesis was the most striking malignant feature of CDC, even compared with other common kidney carcinomas.
