Leukocyte Platelet‐Rich Plasma‐Derived Exosomes Restrained Macrophages Viability and Induced Apoptosis, NO Generation, and M1 Polarization

open access: yesImmunity, Inflammation and Disease, Volume 12, Issue 11, November 2024.
Exosomes from L‐PRP restrained viability, induced apoptosis and NO generation of macrophages, and promoted M1 polarization, while exosomes from P‐PRP increased M2 polarization. The exosomes from L‐PRP presented a more effective effect on macrophages than that from P‐PRP, making it a promising strategy for chronic refractory wound management.
