Study Identifies CD82–Cholesterol Switch That Drives Vascular Leakage

Peer-reviewed results in Nature Cardiovascular Research point to a targetable pathway for curbing inflammation-driven vessel permeability.

Overview

  • University of Oklahoma scientists report that eliminating CD82 in blood vessels substantially reduced leakage and inflammation in animal models.
  • The team found that CD82 interacts with a pool of accessible membrane cholesterol to trigger intracellular signaling that weakens endothelial barriers.
  • Lowering the accessible cholesterol pool with a statin strengthened vessel walls and decreased leakage in preclinical experiments.
  • Models included SARS-CoV-2–inoculated mice, where CD82 ablation was associated with reduced pulmonary leukocyte infiltration.
  • The group received new NIH support, including NHLBI award R01HL173312, to extend this research toward translation while emphasizing that the findings remain preclinical.
