    Occludin (OCLN) is essential for maintaining vascular endothelial barrier integrity and regulating intercellular signaling in cardiovascular health.

  • 2

    Dysfunction of OCLN is linked to cardiovascular and cerebrovascular diseases, including ischemic stroke and atherosclerosis, through increased vascular permeability.

  • 3

    OCLN regulates inflammatory responses and oxidative stress by interacting with signaling pathways like NF-κB and MAPK, exacerbating vascular damage.

  • 4

    Recent findings suggest OCLN has non-classical roles in endothelial autophagy and metabolic reprogramming, indicating its multifaceted impact on disease.

  • 5

    Further research is needed to clarify OCLN's regulatory networks and its potential as a therapeutic target for cardiovascular and cerebrovascular diseases.
