OBJECTIVE
To examine the immunolocalisation of stromal cell derived factor 1 (SDF-1) and its receptor CXCR4 in aged control human donor eyes and eyes with age related macular degeneration (AMD).
METHODS
Postmortem eyes from eight aged control donors (mean age 79.8 years) and from 12 donors with AMD
OBJECTIVE
Endostatin, a C-terminal fragment of collagen XVIII (coll XVIII) formed by proteolysis, specifically inhibits endothelial cell migration and proliferation in vitro and potently inhibits angiogenesis and tumor growth in vivo. The purpose of this study was to examine the immunolocalization
Bestrophin is a 68-kDa basolateral plasma membrane protein expressed in retinal pigment epithelial cells (RPE). It is encoded by the VMD2 gene, which is mutated in Best macular dystrophy, a disease characterized by a depressed light peak in the electrooculogram. Recently it was proposed that
The purpose of this study was to examine the localization and relative levels of vascular endothelial growth factor (VEGF; an angiogenic factor) and pigment epithelium-derived factor (PEDF; an antiangiogenic factor) in aged human choroid and to determine if the localization or their relative levels
Retinal pigment epithelial cells (RPE) and the choriocapillaris are on opposite sides of Bruch's membrane and control transport in and out of the retina. In age-related macular degeneration (AMD), they may also be responsible for deposition of material in and on Bruch's membrane and the formation or
Phosphatase enzymes cleave an inorganic phosphate from a substrate. Phosphatase enzyme histochemistry followed by flat-embedding in glycol methacrylate is extremely useful in studying retinal and choroidal vascular development and loss, since only viable blood vessels have these enzyme activities.
BACKGROUND
There is increasing evidence that inflammation and immune-mediated processes (complement activation) play an important role in age-related macular degeneration (AMD) pathogenesis. A genetic variation in the gene encoding complement factor H (CFH) and plasma levels of C-reactive protein
OBJECTIVE
Evidence implicating oxidative stress in the pathogenesis of age-related macular degeneration suggests that antioxidant therapy could play a role in preventing its progression. The aim of this study was to determine whether derivatives of the triterpenoid (TP)
OBJECTIVE
Inflammation has been implicated in age-related macular degeneration (AMD). This study investigates the association of mast cells (MCs), a resident choroidal inflammatory cell, with pathological changes in AMD.
METHODS
Human donor eyes included aged controls (n=10), clinically diagnosed
OBJECTIVE
An image-analysis technique was developed to quantify changes in the retinal pigment epithelium (RPE) and choriocapillaris in eyes of deceased donors with age-related macular degeneration (AMD).
METHODS
Both eyes of two donors with AMD and of one normal control donor were used to develop
OBJECTIVE
The purpose of this study was to examine the relationships between choriocapillaris (CC) and retinal pigment epithelial changes in age-related macular degeneration (AMD). Morphologic changes in the retinal pigment epithelium (RPE)/choriocapillaris complex were quantified in dry and wet
Nitric oxide (NO) production by vascular endothelium is important in regulation of blood flow. Reduced production of NO can adversely affect blood flow and other vascular functions. We investigated the expression of three nitric oxide synthase (NOS) isoforms in retina and choroid of aged human eyes
OBJECTIVE
Choroidal neovascularization plays an important role in pathogenesis of age-related macular degeneration. Induction of neovascularization by laser photocoagulation in the rat fundus is an established animal model in which the effects of new therapeutic approaches are assessed. The purpose
Retinal pigment epithelium (RPE) plays a critical role in vertebrate vision by providing functional and structural support to the retina. Degeneration of RPE by cumulative oxidative stresses or acute injury frequently results in retinal degenerative diseases, notably age-related macular degeneration
This review summarizes the latest findings in the literature of Angiopoietin-2 (Ang-2), Tyrosine-protein kinase receptor (Tie-2) complex, and faricimab along with their involvement for the treatment of retinal vascular diseases in various clinical trials. In ischemic diseases, such as diabetic
