Introduction: The neuron-specific K-Cl cotransporter KCC2 maintains low intracellular chloride levels, which are crucial for fast GABAergic and glycinergic neurotransmission. KCC2 also plays a pivotal role in the development of excitatory glutamatergic neurotransmission by promoting dendritic spine maturation. The cytoplasmic C-terminal domain (KCC2-CTD) plays a critical regulatory role in the molecular mechanisms controlling the cotransporter activity through dimerization, phosphorylation, and protein interaction.

Analysis of engineered T7 bacteriophages containing genetic sequences encoding antimicrobial peptides.

Front Antibiot

January 2025

Institute of Bioanalytical Chemistry, Faculty of Chemistry and Mineralogy, Center for Biotechnology and Biomedicine, Leipzig University, Leipzig, Germany.

Because of the global spread of multi- and pan-resistant bacteria, there is a need to identify, research, and develop new strategies to combat these pathogens. In a previous proof-of-concept study, we presented an innovative strategy by genetically modifying lytic T7 bacteriophages. We integrated DNA fragments encoding for derivatives of the antimicrobial peptide (AMP) apidaecin into the phage genome to induce the production and release of apidaecin within the T7 infection cycle, thereby also targeting phage-resistant bacteria.

Quinone extraction drives atmospheric carbon monoxide oxidation in bacteria.

Nat Chem Biol

January 2025

Department of Microbiology, Biomedicine Discovery Institute, Monash University, Clayton, Victoria, Australia.

Diverse bacteria and archaea use atmospheric CO as an energy source for long-term survival. Bacteria use [MoCu]-CO dehydrogenases (Mo-CODH) to convert atmospheric CO to carbon dioxide, transferring the obtained electrons to the aerobic respiratory chain. However, it is unknown how these enzymes oxidize CO at low concentrations and interact with the respiratory chain.

The VHL-containing cullin-RING E3 ubiquitin ligase (CRL2) complex is an E3 ligase commonly used in targeted protein degradation (TPD). Hydroxyproline-based ligands that mimic VHL substrates have been developed as anchor molecules for proteolysis-targeting chimeras (PROTACs) in TPD. To expand the chemical space for VHL ligands, we conducted fragment screening using VHL-ELOB-ELOC (VBC) proteins.

Therapeutic efficacy and safety of adeno-associated virus (AAV) liver gene therapy depend on capsid choice. To predict AAV capsid performance under near-clinical conditions, we established side-by-side comparison at single-cell resolution in human livers maintained by normothermic machine perfusion. AAV-LK03 transduced hepatocytes much more efficiently and specifically than AAV5, AAV8 and AAV6, which are most commonly used clinically, and AAV-NP59, which is better at transducing human hepatocytes engrafted in immune-deficient mice.
