Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Investigating transcription factor dynamics in health and disease using FRAP

open access: yesFEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

COMPLEMENT-MEDIATED ADIPOCYTE LYSIS BY NEPHRITIC FACTOR SERA [PDF]

open access: yes, 1993
Recent data indicate a previously unsuspected link between the complement system and adipocyte biology. Murine adipocytes produce key components of the alternative pathway of complement and are able to activate this pathway.

Therapeutic advances in eculizumab for atypical hemolytic uremic syndrome: a narrative review

open access: yesFrontiers in Pharmacology
Atypical hemolytic uremic syndrome (aHUS) represents an uncommon, life-threatening complement-mediated thrombotic microangiopathy that is linked to both significant renal and extrarenal complications.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

open access: yesFEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Microglial pathological synaptic pruning in epilepsy: pathophysiology and therapeutic potential

open access: yesFrontiers in Immunology
Epilepsy affects around 70 million people worldwide, and roughly one-third of them respond poorly to standard antiepileptic drugs. Current treatments are directed almost entirely at neurons, leaving the contribution of non-neuronal cells largely ...

Structure‐forward targeting of claudins with synthetic binders

open access: yesFEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Neutrophil-mediated injury to endothelial cells. Enhancement by endotoxin and essential role of neutrophil elastase [PDF]

open access: yes, 1986
The neutrophil has been implicated as an important mediator of vascular injury, especially after endotoxemia. This study examines neutrophil-mediated injury to human microvascular endothelial cells in vitro. We found that neutrophils stimulated by formyl-

Treatment of antibody-mediated rejection in heart transplantation: from empirical combination to multi-target precision intervention

open access: yesFrontiers in Immunology
Antibody-mediated rejection (AMR) is the primary immunological obstacle limiting long-term survival in heart transplant recipients. Driven by donor-specific antibodies (DSA), AMR damages graft microvasculature through multiple pathways, including ...
