Extracellular DNA (exDNA)

Target
exDNA
Molecular classification
Nucleic acid
01

Overview

Extracellular DNA (exDNA) refers to DNA located outside of cell membranes. It is found in various environments like ecosystems, biofilms, and bodily fluids, originating from lysed cells or active secretion. It plays roles in structural support, antimicrobial defense, genetic exchange, and cell signaling. Clinically, it serves as a non-invasive diagnostic tool and potential therapeutic target.
