PyroEVs/PLIN3 Mediate Lipid Droplet-Mitochondrial Coupling in Sepsis Endothelial Injury

July 24, 2026 updated by: Fei Peng, Zhongda Hospital

Role and Mechanism of PyroEVs in Regulating Lipid Droplet-Mitochondrial Coupling Via PLIN3 in Sepsis-Induced Vascular Endothelial Cell Injury

Objective: To investigate the correlation of PyroEVs and PLIN3 with the severity and prognosis of sepsis patients.

Participants: Sepsis patients meeting the Sepsis 3.0 diagnostic criteria admitted to the Intensive Care Unit of Zhongda Hospital affiliated with Southeast University, as well as healthy volunteers.

Inclusion Criteria:

  1. Presence of confirmed or suspected infection;
  2. Sequential Organ Failure Assessment (SOFA) score increase ≥ 2 points from baseline;
  3. Signed informed consent. Exclusion Criteria: Age < 18 or > 80 years, pregnancy, cancer patients, and individuals with diseases potentially complicated by vascular endothelial cell injury.

Primary outcome: 28-day mortality, SOFA score
