Versatile vector tools for efficient protein screening across multiple expression systems

FEBS Open Bio, EarlyView.
A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

The biology of bacterial peptidoglycans and their impact on host immunity and physiology

, 2014
International audiencePeptidoglycans (PGN) are a constituent of the bacterial cell wall, and are shed as bacteria divide. The presence of PGN is therefore a marker of bacterial activity that has been exploited by both plants and animals to induce defence

Biology of host-dependent restriction-modification in prokaryotes

EcoSal Plus
ABSTRACT Understanding the mechanisms that modulate horizontal genetic exchange in prokaryotes is a key problem in biology. DNA entry is limited by resident host-dependent restriction-modification (RM) systems (HDRM), which are present in most prokaryotic genomes.

Directed evolution of enzymes at the crossroads of tradition and innovation

FEBS Open Bio, EarlyView.
An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Small RNAs, big impact: microRNAs in malaria pathogenesis, therapeutic opportunities, and challenges

Frontiers in Cellular and Infection Microbiology
Malaria is one of the world’s most critical parasitic diseases; it is caused by Plasmodium species and spreads through Anopheles mosquitoes. The life cycle of Plasmodium species is complex and involves several stages in humans and mosquitoes, each ...

Pathways and pitfalls: a qualitative study of student experiences in biomedical science education

FEBS Open Bio, EarlyView.
Biomedical science students from underrepresented backgrounds face barriers including financial strain, disrupted laboratory access and cultural exclusion. Peer networks provide vital support when institutional systems are difficult to navigate. To create inclusive learning environments and achieve academic success, educators should blend active, hands‐

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

FEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral
