Overview

Randomized trial reveals caveolins influence inflammation and vascular function in nAMD and PCV, suggesting new treatments.

Key Points

  • This study investigates the cellular and molecular mechanisms of neovascular age-related macular degeneration and polypoidal choroidal vasculopathy, focusing on caveola-resident proteins.
  • Collected peripheral blood mononuclear cells (PBMCs) from 10 patients with nAMD/PCV and 9 healthy controls
  • Analyzed 22,593 monocytes for differentially expressed genes and conducted Gene Set Enrichment Analysis (GSEA)
  • Performed functional assays and cytokine profiling with mRNA transfections in THP-1 and HUVECs.
  • GSEA showed negative enrichment of caveola in classical monocytes of PCV (NES = -1.769, P = 0.001, q = 0.026)
  • Caveolin-1/2 overexpression in monocytes increased proinflammatory mediators, enhancing monocyte adhesion but inhibiting transendothelial migration
  • CAV1/2 overexpression in HUVECs altered cytokine profiles and significantly inhibited tube formation.
