Phage defense origin of animal immunity

Curr Opin Microbiol. 2023 Apr 1;73:102295. doi: 10.1016/j.mib.2023.102295. Online ahead of print.ABSTRACTThe innate immune system is the first line of defense against microbial pathogens. Many of the features of eukaryotic innate immunity have long been viewed as lineage-specific innovations, evolved to deal with the challenges and peculiarities of multicellular life. However, it has become increasingly apparent that in addition to evolving their own unique antiviral immune strategies, all lifeforms have some shared defense strategies in common. Indeed, critical fixtures of animal innate immunity bear striking resemblance in both structure and function to the multitude of diverse bacteriophage (phage) defense pathways discovered hidden in plain sight within the genomes of bacteria and archaea. This review will highlight many surprising examples of the recently revealed connections between prokaryotic and eukaryotic antiviral immune systems.PMID:37011504 | DOI:10.1016/j.mib.2023.102295
