Compact 9dBEs Enable Efficient and Precise Genome Editing in Mammalian Cells and In Vivo

Advanced Science, EarlyView.
As a compact type II‐D system, the Cas9d‐based platform holds great potential for in vivo applications. Through rational engineering, its derived base editors (9dBEs) enable efficient disease modeling while facilitating single‐vector AAV delivery for in vivo genome editing. These miniature tools offer a robust strategy for basic research and biomedical

Streptococcal Mannose Phosphotransferase System Component IID Is a Novel RANK‐Binding Osteoclastogenic Factor

Advanced Science, EarlyView.
Streptococcal mannose phosphotransferase system component IID (Man‐PTSIID) is identified as a novel RANK‐binding osteoclastogenic factor. By directly binding to RANK and activating NF‐κB independently of TLR2, Man‐PTSIID drives osteoclastogenesis and inflammatory bone destruction, uncovering an unexpected microbial mechanism underlying streptococcal ...

One‐Step Immobilized Phage Depolymerase Coatings for Catheter‐Related Bloodstream Infections

Advanced Science, EarlyView.
Catheter‐related bloodstream infections (CRBSI) caused by drug‐resistant Gram‐negative bacteria remain a major clinical challenge. Here, a polydopamine‐assisted depolymerase coating degrades bacterial capsules and restores serum‐mediated killing, effectively suppressing biofilms and reducing bacterial burden in vitro, ex vivo, and in vivo, presenting a

A Synthetic Platform for Antibody Junctional Diversification Beyond Natural Constraints

Advanced Science, EarlyView.
ARESEC is a synthetic platform that reconstructs functional V(D)J recombination in HEK293T cells. By introducing RSS elements and co‐expressing RAG1/2 and TdT across all three antibody CDRs, it enables programmable junctional diversification and direct generation of high‐affinity variants targeting PD‐1/PD‐L1, overcoming the evolutionary constraints of

Characterization and antibiofilm efficacy of the Pseudomonas aeruginosa phage HKPH_J3

International Journal of Medical Microbiology
In recent years, due to the spread of antibiotic resistance, Pseudomonas aeruginosa has emerged as an ESKAPE super-resistant pathogen, posing a major threat to current therapies. Phage therapy is currently one of the most promising treatment methods.

Functional–Taxonomic Scaling Resolves Conflicting Average Genome Size Estimates Across Environmental Gradients

Advanced Science, EarlyView.
Based on genome size‐functional breadth theory, we introduce and validate a framework that adjudicates conflicting average genome size (AGS) estimates by testing which estimate yields a gap between scaled functional diversity and scaled taxonomic diversity that is consistent with the expected positive association between genome size and gene functional

Phage-resistant and phage-carrying strains of lactic streptococci [PDF]

Journal of Hygiene, 1947
1. The types of resistance acquired by certain related strains of Str. cremoris as a result of phage action were investigated.2. Some partially resistant forms of Str. cremoris were able to ‘carry’ phage in symbiotic association when subcultured daily in milk for long periods of time.3.

Engineered Transformer Base Editor with Enhanced Editing Efficiency

Advanced Science, EarlyView.
A highly efficient transformer base editor system achieves robust genomic editing in a humanized mouse model. This work establishes a versatile and translatable platform, opening new avenues for precision gene therapy. ABSTRACT Canonical cytosine base editors (CBEs) achieve precise C‐to‐T conversions without inducing DNA double‐strand breaks (DSBs ...
