Patch Testing in Paediatric Drug Hypersensitivity Reactions: Current Evidence and Clinical Implications

Contact Dermatitis, EarlyView.
ABSTRACT Drug hypersensitivity reactions (DHRs) are common in children and are diagnostically challenging, with cutaneous manifestations being the most common presentation. Patch testing (PT) is a well‐established tool for investigating delayed T‐cell‐mediated reactions and is widely used in patients with contact dermatitis.

Heat Stress Triggers Nuclear Invagination and Spatial Compartmentalization of Protein Metabolism

Cell Proliferation, EarlyView.
Cells adapt heat stress to shape a nuclear invagination region function as “protein metabolism hotspots”, where both protein production and degradation are enhanced. ABSTRACT Heat stress is a common challenge for cells, causing multiple types of cellular damage while triggering complex stress responses, including the highly conserved mechanism known as

A new branch of mammalian vitamin B6 metabolism: AKR1C‐mediated conversion of pyridoxal to pyridoxine and 4‐pyridoxolactone

The FEBS Journal, EarlyView.
Pyridoxal 5′‐phosphate (PLP) homeostasis relies on salvage enzymes, yet key metabolic branches remain undefined. We identify AKR1C isozymes as previously undescribed contributors that convert pyridoxal into pyridoxine or 4‐pyridoxolactone through reductase and dehydrogenase activities.

Investigating transthyretin variants H88R and I107V in amyloid priming: From destabilization to complete dissociation

The FEBS Journal, EarlyView.
Investigated mutations in transthyretin (TTR) disrupt the F87‐centered hydrophobic core that stabilizes its tetrameric structure. The mild I107V mutation weakens inter‐chain packing, while H88R fully abolishes tetramer formation, yielding a monomeric, aggregation‐prone form. Structural, biophysical, and computational analyses reveal that both mutations

Cryo‐EM structures of multiple‐peptide resistance factor (MprF) from Pseudomonas aeruginosa

The FEBS Journal, EarlyView.
Cryo‐EM analysis of MprF from Pseudomonas aeruginosa reveals a dimeric enzyme, distinct from Rhizobium homologues. The soluble GNAT domain contains a dynamic amphipathic helix (TTH) that adopts different positions in detergent micelle and nanodisc, relative to the membrane.
