Article Abstract

Sasaki and colleagues [1] (JCI Insight 2018;3,e96902) identified the leukocyte inflammatory lipid mediator leukotriene B4 (LTB4)/LTB4 receptor 1 receptor-signaling axis in M2 macrophages as a causal pathway for the vascular endothelial growth factor-dependent pathological neovascularization in a mouse model that mimics wet age-related macular degeneration. This observation provides a novel mechanism by which an eicosanoid lipid mediator drives retinal vascular pathology and suggests a novel therapeutic target for proliferative retinal vascular diseases.

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.

Background: Colorectal cancer (CRC) remains one of the leading causes of cancer-related mortality worldwide. The tumor microenvironment (TME), particularly the interactions between endothelial cells and cancer-associated fibroblasts (CAFs), plays a pivotal role in promoting tumor growth, angiogenesis, oxidative stress, and therapy resistance. The HUVEC-fibroblast co-culture model closely mimics stromal-endothelial interactions observed in CRC, enabling mechanistic insights not achievable in monocultures.

Rheumatoid arthritis (RA) is an autoimmune disorder characterized by synovial hyperplasia and pannus formation, which serves as its primary pathological feature and may ultimately result in joint deformities. Lysyl oxidase (LOX) is involved in the formation and remodeling of the extracellular matrix, but its role in RA is not yet clear. This study aims to investigate the mechanism of lysyl oxidase (LOX) in synovial hyperplasia and pannus formation associated with rheumatoid arthritis (RA).

Pathological myopia is one of the primary causes of irreversible visual loss in the population. Myopic maculopathy represents a key feature of pathological myopia, among which macular atrophy is the main contributor to severe visual impairment. The specific mechanism underlying the development of macular atrophy remains unclear.

Background: Retinopathy of prematurity (ROP), an oxygen-induced retinopathy (OIR), triggers a series of vascular lesions and inflammatory responses and results in visual impairment or even blindness. Triptolide (TP) possesses many pharmacological properties, including immunosuppressive and anti-tumour effects. However, the effects of TP on ROP and its underlying mechanisms remain unclear.
