The angiopoietin (Ang)-Tie axis, critical for endothelial cell function and vascular development, is a promising therapeutic target for treating vascular disorders and inflammatory conditions like sepsis. This study aimed to enhance the binding affinity of recombinant Ang1 variants to the Tie2 and explore their therapeutic potential. Structural insights from the Ang1-Tie2 complex enabled the identification of key residues within the Ang1 receptor binding domain (RBD) critical for Tie2 interaction.

Purpose: Chronic inflammation plays an important role in the pathogenesis of choroidal neovascularization (CNV). This study aimed to investigate the effect of the CHF5074, a γ-secretase inhibitor, on angiogenesis in a laser-induced CNV model and elucidate its possible molecular mechanism.
Methods: Male C57/BL6J mice aged between 6 to 8 weeks were employed to set up a laser-induced model of CNV.

Electrospinning, a technique for creating fabric materials from polymer solutions, is widely used in various fields, including biomedicine. The unique properties of electrospun fibrous membranes, such as large surface area, compositional versatility, and customizable porous structure, make them ideal for advanced biomedical applications like tissue engineering and wound healing. By considering the high biocompatibility and well-known regenerative potential of polylactic acid (PLA) and chitosan (CH), as well as the versatile antibacterial effect of silver nanoparticles (AgNPs), this study explores the antibacterial efficacy, adhesive properties, and cytotoxicity of electrospun chitosan membranes with a unique nanofibrous structure and varying concentrations of AgNPs.

Chronic non-healing wounds are a common complication of diabetes, marked by impaired angiogenesis. This study explores how exosomes (Exo-miR-1248) from miR-1248-overexpressing adipose-derived stem cells enhance diabetic wound healing by modulating endothelial cell function. Adipose-derived stem cells were transfected with a lentivirus carrying miR-1248 to produce Exo-miR-1248, isolated via differential centrifugation.
