OLD sentinel: an abortive tRNase surveys phage replication and DNA defects in RecBCD-compromised cells

This paper characterizes OLD, an abortive immunity protein, revealing its structure and activation mechanism in response to phage replication and DNA defects in RecBCD-compromised cells.

Phages infecting the common gut commensal Escherichia coli HS reveal tropism for its Klebsiella-like capsule

The paper identifies phages infecting E. coli HS, shows their resistance to restriction via modifications, and links phage infection to a Klebsiella-like capsule.

Amyloid conformers of the FXR1 protein prevent mRNA degradation in cortical neurons

The paper identifies FXR1 amyloid conformers in rat brain that bind and protect mRNAs from degradation, suggesting a functional role in RNA stability.
