Resistance is not futile: bacterial 'innate' and CRISPR-Cas 'adaptive' immune systems
1Department of Microbiology and Immunology, University of Otago, PO Box 56, Dunedin 9054, New Zealand.
Abstract:
Bacteria are under a constant pressure from their viruses (phages) and other mobile genetic elements. They protect themselves through a range of defence strategies, which can be broadly classified as 'innate' and 'adaptive'. The bacterial innate immune systems include defences provided by restriction modification and abortive infection, among others. Bacterial adaptive immunity is elicited by a diverse range of CRISPR-Cas systems. Here, I discuss our research on both innate and adaptive phage resistance mechanisms and some of the evasion strategies employed by phages.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
