Lipid Nanoparticle‐Mediated CRISPR‐Cas13a Delivery for the Control of Bacterial Infection
New formulations of lipid nanoparticles (LNPs) that can deliver nucleic acids to Gram‐negative bacteria are proposed to combat bacterial infection. The delivery of nucleic acids by LNPs is aided by LNP‐helpers which weaken the bacterial outer membrane. LNPs encapsulating the Cas13a/gRNA expression vector achieve an antibacterial effect in both in vivo ...

Characterization of endonuclease activities in Moloney murine leukemia virus and its replication-defective mutants [PDF]
To study Moloney murine leukemia virus (M-MulV) proteins associated with the integration of proviral DNA into the host chromosome, we isolated endonuclease activities from purified virion preparations of the wild type and two of its replication mutants ...

Endonuclease II of coliphage T4: a recombinase disguised as a restriction endonuclease? [PDF]
EndoII shares with restriction endonucleases the property of cleaving foreign DNA while leaving the endonuclease‐encoding genome intact, ensuring the survival of one DNA species in the cell. In addition, in vivo EndoII cleaves a specific DNA sequence and cleavage is context dependent. These context effects extend over at least 1000 bp, largely limiting

Dissecting endonuclease and exonuclease activities in endonuclease V from Thermotoga maritima [PDF]
Endonuclease V is an enzyme that initiates a conserved DNA repair pathway by making an endonucleolytic incision at the 3'-side 1 nt from a deaminated base lesion. DNA cleavage analysis using mutants defective in DNA binding and Mn(2+) as a metal cofactor reveals a novel 3'-exonuclease activity in endonuclease V [Feng,H., Dong,L., Klutz,A.M ...

This study develops a multifunctional CRISPR‐dCas9‐based OMV platform termed OMV‐C9I12, which facilitates the coexpression of CXCL9 and IL‐12 within tumor cells. This platform enhances T cell recruitment and activation, synergizes with anti‐PD‐1/PD‐L1 immunotherapy, and amplifies antitumor T cell immunity.
