CRISPR–Cas regulates expression of embedded anti-phage defence systems
Nature, Published online: 22 July 2026; doi:10.1038/s41586-026-10833-9CRISPR–Cas systems transcriptionally tune diverse innate defences using CRISPR RNA-like guides to balance antiviral protection with fitness, and hyperactivate these defences when compromised, establishing a layered bacterial ‘immunity guard’ network.
