Phage-encoded CasPRs transcriptionally silence diverse CRISPR-Cas systems

Edith M Sanderson, Julieta Peralta, Sam Nouwens, Luke Oriolt, Victoria M. Hayes, Brett K. Kaiser, Alexander J. Meeske

The paper identifies CasPRs, DNA-binding anti-CRISPRs that silence CRISPR-Cas systems by blocking transcription, and shows their activity against different CRISPR types.

Surviving phage attack primes bacterial immunity to defeat counterdefenses

Reid T. Oshiro, Alyssa Pratt, Drew T. Dunham, Lindsey Doyle, Clare Gill, Ani Chouldjian, Kerilyn Higashi, Julieta Peralta Acosta, Sydney McGuire, Sam Nouwens, Brett K. Kaiser, Kimberley D. Seed

The paper shows that restricted phage infection primes bacterial immunity to defeat counterdefenses by increasing defense protein abundance and altering host-phage stoichiometry.
