  • RESEARCH PROGRESS OF NEURAL REGULATION MECHANISM OF VASCULOGENESIS

    ObjectiveTo review the research progress of neural regulation mechanism of vasculogenesis. MethodsThe relevant literature on neural regulation mechanism of vasculogenesis was extensively reviewed. ResultsNeural regulation of vasculogenesis depends on synergistic effect among various cells of neurovascular unit, and co-participation of multiple cytokines, and it is closely related to a variety of repair mechanism, such as nerve regeneration and synaptic plasticity, but the specific mechanism need to be further investigated. ConclusionThe research of the neural regulation mechanism of vasculogenesis will contribute to further understanding repair mechanism of nerves and vessels injuries.

  • Advances in the effect of neurovascular unit in retinal physiological and pathological process

    Neurovascular unit (NVU) refers to a functional complex of neural cells and vasculature, which plays an important role in maintaining retinal homeostasis and matching metabolic demands. In physiological situation, retinal NVU mainly exerts two effects: (1) maintaining blood-retinal barrier for retinal homeostasis maintenance; (2) regulating local blood flow to meet metabolic and functional demands of the retina. The pathological changes in retinal diseases are reflected in each functional part of retinal NVU, including cell-cell connections, signal pathways, metabolic activities and cellular functions. However, the main pattern and manifestation of NVU impairment differs among retinal diseases due to different etiologies. At present, understanding on retinal NVU is still insufficient, and its clinical application is even more limited. Further application in the diagnosis and treatment of retinal diseases is an important direction for future research on NVU.

  • Research progress on the bidirectional effect of autophagy on retinal neurovascular unit cells in diabetic retinopathy

    Diabetes retinopathy (DR) is a blinding ocular complication of diabetes, and its pathological mechanism is complex. The damage to the retinal neurovascular unit (NVU) and the imbalance of its coupling mechanism are important pathological foundations. Autophagy plays an important role in the progression of DR. Oxidative stress, endoplasmic reticulum stress, hypoxia, and competitive endogenous RNA regulatory networks can affect the occurrence of autophagy, and autophagy induced cell death is crucial in NVU dysfunction. Retinal neurocyte are non- renewable cells, and adaptive autophagy targeting neuronal cells may provide a new direction for early vision rescue in patients with DR. It is necessary that exploring the possible autophagy interrelationships between ganglion cells, glial cells, and vascular constituent cells, searching for targeted specific cell autophagy inhibitors or activators, and exploring the impact of autophagy on the NVU complex more comprehensively at the overall level. Adopting different autophagy intervention methods at different stages of DR may be one promising research directions for future DR.
