  • Seminarium

The seminar will cover the adaptive immune system of bacteria, its function and how it is regulated.

Viruses (bacteriophages) is a threat to a bacteria and an important factor in their ecology and evolution.  Bacteria have evolved several immune systems against viruses and the most sophisticated one is CRISPR-Cas that can learn to recognize and defeat new viruses by saving fragments of their genetic material. Peter Fineran will present how the system works and his own research on the topic, with focus on how and when the system is activated. The presentation will be given in english.
