Special Issue Information

Dear Colleagues,

Vascular endothelial growth factors (VEGFs) play a central role in regulating physiological angiogenesis. However, in several pathological conditions, such as in cancer, in cardiovascular diseases and in retinopathy, the physiological and protective role of VEGs could deviate and become deleterious, inducing the increased permeability of the endothelium, decreased inhibition of pro-apoptotic proteins and activation of inflammation. Anti-VEGF therapy strategies have been developed and approved for clinical use in cancer and retinopathy, but at the moment, anti-VEGF treatments require careful patient selection and monitoring. In addition, sometimes they fail to promote appropriate beneficial adaptive responses. The present Special Issue of Cell aims to summarize some of the latest advances in understanding the role of VEGFs in cancer, cardiovascular diseases and retinopathies, focusing on the involved cellular pathways, neuroinflammation and signaling pathways. We also welcome manuscripts that address therapeutic strategies in this field. For this purpose, we are encouraging basic and clinical researchers to present their valuable work as a scientific contribution or review articles. We would appreciate your contribution, and it will be a pleasure for us to receive your manuscripts. Our aim is to provide a comprehensive update on the role of VEGFs in disease and on their therapy options.

The development of choroidal neovascularization (CNV) is a crucial factor in the pathophysiology and prognosis of exudative age-related macular degeneration (AMD). Therefore, the detection of CNV is essential for establishing an appropriate diagnosis and treatment plan. Current ophthalmic imaging techniques, such as fundus fluorescent angiography and optical coherence tomography, have limitations in accurately visualizing CNV lesions and expressing CNV activity, owing to issues such as excessive dye leakage with pooling and the inability to provide functional information. Here, using the arginine−glycine−aspartic acid (RGD) peptide’s affinity for integrin αvβ3, which is expressed in the neovascular endothelial cells in ocular tissues, we propose the use of fluorescein isothiocyanate (FITC)-labeled RGD peptide as a novel dye for effective molecular imaging of CNV. FITC-labeled RGD peptides (FITC-RGD2), prepared by bioconjugation of one FITC molecule with two RGD peptides, demonstrated better visualization and precise localization of CNV lesions than conventional fluorescein dyes in laser-induced CNV rodent models, as assessed using various imaging techniques, including a commercially available clinical fundus camera (Optos). These results suggest that FITC-RGD2 can serve as an effective novel dye for the diagnosis of neovascular retinal diseases, including AMD, by enabling early detection and treatment of disease occurrence and recurrence after treatment.
