Reconstructing enzyme evolution by protein engineering

FEBS 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 ...

Backbone dynamics of complement control protein (CCP) modules reveals mobility in binding surfaces [PDF]

, 2004
The regulators of complement activation (RCA) are critical to health and disease because their role is to ensure that a complement-mediated immune response to infection is proportionate and targeted.

Components of the alternative complement pathway in patients with psoriasis

Acta Dermatovenerologica Alpina Pannonica et Adriatica, 2017
Psoriasis is a chronic inflammatory skin disease. Adipose tissue plays important roles in the events that regulate body metabolism. This study determined the levels of complement 3 ( C3), acylation-stimulating protein (ASP), and adipsin, which take part in the alternate complement pathway, and are synthesized in and secreted by adipose tissue.Thirty ...

Investigating transcription factor dynamics in health and disease using FRAP

FEBS 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 ...

Activation of the Alternative Complement Pathway by Fungal Melanins [PDF]

Clinical and Vaccine Immunology, 2002
ABSTRACTMelanins are complex biological pigments formed by the oxidative polymerization of phenolic and/or indolic compounds. These pigments have been implicated in the pathogenesis of some microbial infections, malignancies, degenerative disorders, and autoimmune diseases.

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

FEBS 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.

The lectin pathway of complement activation is a critical component of the innate immune response to pneumococcal infection.

PLoS Pathogens, 2012
The complement system plays a key role in host defense against pneumococcal infection. Three different pathways, the classical, alternative and lectin pathways, mediate complement activation.

Small-molecule factor D inhibitors selectively block the alternative pathway of complement in paroxysmal nocturnal hemoglobinuria and atypical hemolytic uremic syndrome

Haematologica, 2017
Paroxysmal nocturnal hemoglobinuria and atypical hemolytic uremic syndrome are diseases of excess activation of the alternative pathway of complement that are treated with eculizumab, a humanized monoclonal antibody against the terminal complement ...

Activation of the alternative complement pathway by Naegleria fowleri [PDF]

Infection and Immunity, 1980
Naegleria fowleri amoebae were lysed by adult fresh human serum, and their multiplication was inhibited in culture medium supplemented with 10% fresh human serum. Heat inactivation (56 degrees C, 30 min) of serum abrogated these lytic and inhibitory effects.
