Nature, Published online: 22 July 2026; doi:10. 1038/s41586-026-10833-9 CRISPR–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.
