Discovery explains how immune cells target DNA mutations to improve antibodies

AI Summary

Researchers at the Montreal Clinical Research Institute and Université de Montréal described how immune cells direct a mutagenic enzyme to specific DNA regions while limiting damage elsewhere in the genome. The findings may clarify mechanisms involved in antibody improvement, though the supplied report does not specify clinical applications.

Scientists at the Montreal Clinical Research Institute (IRCM), led by Université de Montréal medical professor Javier Di Noia, have shed light on a fundamental mystery in immunology: How do immune cells manage to concentrate a powerful mutagenic enzyme at precisely defined regions of DNA while largely sparing the rest of the genome from potentially dangerous damage?
