In developed countries, the leading causes of blindness such as diabetic retinopathy are characterized by disorganized vasculature that can become fibrotic. Although many such pathological vessels often naturally regress and spare sight-threatening complications, the underlying mechanisms remain unknown. Here, we used orthogonal approaches in human patients with proliferative diabetic retinopathy and a mouse model of ischemic retinopathies to identify an unconventional role for neutrophils in vascular remodeling during late-stage sterile inflammation. Senescent vasculature released a secretome that attracted neutrophils and triggered the production of neutrophil extracellular traps (NETs). NETs ultimately cleared diseased endothelial cells and remodeled unhealthy vessels. Genetic or pharmacological inhibition of NETosis prevented the regression of senescent vessels and prolonged disease. Thus, clearance of senescent retinal blood vessels leads to reparative vascular remodeling.

We developed an effective nanoparticle-biomaterial in alleviating diabetic retinopathy (DR), hyaluronic acid (HA)-CeO2, composed mainly of CeO2 and HA. To demonstrate its anti-DR capacity, retinal cells from a B6/J mouse model were used to compare the efficiency of PEI-CeO2 and HA-CeO2. We investigated the transport performance, histolysis, immune cell infiltration, angiogenesis, and hyperemia induced by the transport system. The structural integrity, microvascular apoptosis, and superoxide and peroxide concentrations in the retina were measured to evaluate the clinical efficacy of CeO2. The infiltration efficiency of HA-CeO2 was higher than that of PEI-CeO2. Lower levels of foreign body reaction were evident for HA-CeO2 with less histolysis, immune cell infiltration, angiogenesis, and hyperemia. The clinical efficacy of HA-CeO2 in terms of preservation of retinal structure and lowering of microvascular apoptosis and superoxide and peroxide concentrations was superior to those of PEI-CP. HA-CeO2 was shown to have significant antioxidation and anti-vascular injury capacity in a mouse model, and may be a potential compound nanodrug for DR treatment in the future.
