Cancer Cells’ Ability to Escape Immunity is Pre-Existing, DNA Barcoding Study Says

November 8, 2022

Via: GEN

Immunoediting (the process by which cancer cells evade the immune system) results when cancer cells that are more immunogenic are selectively eliminated, resulting in a population of less-immunogenic cancer cells that are able to expand. In a new study, researchers used a DNA barcoding method to analyze immunoediting in vivo. Looking at both primary tumors and metastases, the researchers asked whether resistance to immune checkpoint inhibition develops from pre-existing or de novo-generated cell populations.
