Research overview

To dissect the mechanism underlying the protective role of Exos in S-AKI, we examined the proteins within Exos by mass spectrometry and found that CD5L was the most upregulated protein in FRC-Exos compared to macrophage-derived Exos. Thus, strategies to modify FRC-Exos could be a new avenue in developing therapeutics against kidney injury.

Key findings

Sepsis-induced acute kidney injury (S-AKI) is highly lethal, and effective drugs for treatment are scarce.

Previously, we reported the robust therapeutic efficacy of fibroblastic reticular cells (FRCs) in sepsis.

Here, we demonstrate the ability of FRC-derived exosomes (FRC-Exos) to improve C57BL/6 mouse kidney function following cecal ligation and puncture-induced sepsis.

In vivo imaging confirmed that FRC-Exos homed to injured kidneys.
