An evolving function of DNA-containing exosomes in chemotherapy-induced immune response

Abstract

Chemotherapy is a predominant strategy to treat cancer and is often associated with toxicities like severe diarrhea that puts patients at additional risk and can hinder treatment strategies. Lian et al. recently explored the immune-mediated mechanisms of Irinotecan-induced diarrhea in colorectal cancer and found that double-stranded DNA in small vesicles can launch inflammation pathways in immune cells through the cytosolic DNA sensor AIM2.
