Kidney-Specific Membrane-Bound Serine Proteases CAP1/Prss8 and CAP3/St14 Affect ENaC Subunit Abundances but Not Its Activity

Simona Frateschi, Sévan Stroh

The serine proteases CAP1/Prss8 and CAP3/St14 are identified as ENaC channel-activating proteases in vitro, highly suggesting that they are required for proteolytic activation of ENaC in vivo. The present study tested whether CAP3/St14 is relevant for rena ...

Assessment of metal-based dihydrofolate reductase inhibitors on a novel mesofluidic platform

Paul Joseph Dyson, Sarah Alexandra Pais Pereira

A new miniaturized micro sequential injection coupled with the lab-on-valve (mu SIA-LOV) technique was full-blown to perform inhibitory studies on dihydrofolate reductase (DHFR). The system was used to evaluate the DHFR inhibition activity of metal-based a ...

Bacterial matrix metalloproteases and serine proteases contribute to the extra-host inactivation of enteroviruses in lake water

Tamar Kohn, Virginie Bachmann

Enteroviruses are ubiquitous contaminants of surface waters, yet their fate in presence of microbial congeners is poorly understood. In this work, we investigated the inactivation of Echovirus-11 (E11) and Coxsackievirus-A9 (CVA9) by bacteria isolated from ...

De novo developed small cyclic peptides that are orally available

Manuel Leonardo Merz

Cyclic peptides are ring-shaped molecules that emerged as a promising class of therapeutics. While it is often difficult to find small molecule binders for challenging disease targets, cyclic peptides can bind to featureless surfaces or inhibit protein-pro ...

Boosted Pro-Inflammatory Activity in Human PBMCs by Lipopolysaccharide and SARS-CoV-2 Spike Protein Is Regulated by alpha-1 Antitrypsin

Florian Maria Wurm, Divor Kiseljak

For the treatment of severe COVID-19, supplementation with human plasma-purified alpha-1 antitrypsin (AAT) to patients is currently considered. AAT inhibits host proteases that facilitate viral entry and possesses broad anti-inflammatory and immunomodulato ...

Novel inhibitors of kallikrein proteases and uses thereof

Christian Heinis, Alessandro Zorzi, Patrick Andreas Gonschorek

The present invention relates to a cyclic inhibitor of a kallikrein protease comprising or consisting of (I) the peptide (X1 (X2)(X3)R(X4)(X5)(X6)(X7)(X8)(X9)(X10)(X11) (Formula (X)), wherein (X1) is present or absent and, is preferably present, and if pre ...

Human proteinase 3 resistance to inhibition extends to alpha-2 macroglobulin

Marc Moniatte

Polymorphonuclear neutrophils contain at least four serine endopeptidases, namely neutrophil elastase (NE), proteinase 3 (PR3), cathepsin G (CatG), and NSP4, which contribute to the regulation of infection and of inflammatory processes. In physiological co ...

Pharmacological disruption of the Notch transcription factor complex

Freddy Radtke, Ute Koch, Nadine Fournier, Jelena Zaric, Rajwinder Lehal, Linlin Cao, Michele Vigolo

Notch pathway signaling is implicated in several human cancers. Aberrant activation and mutations of Notch signaling components are linked to tumor initiation, maintenance, and resistance to cancer therapy. Several strategies, such as monoclonal antibodies ...

Salt enhances the thermostability of enteroviruses by stabilizing capsid protein interfaces

Tamar Kohn, Matteo Dal Peraro, Simon Meister, Alessio Prunotto

Enteroviruses are common agents of infectious disease that are spread by the fecal-oral route. They are readily inactivated by mild heat, which causes the viral capsid to disintegrate or undergo conformational change. While beneficial for the thermal treat ...

Development of Tissue Kallikrein Inhibitors for the Treatment of Netherton Syndrome

Patrick Andreas Gonschorek

There is currently no approved treatment for Netherton syndrome, which is a severe, genetic skin disease characterized by chronic inflammation and excessive peeling of the skin. Even though the molecular disease mechanism has been assigned to the unopposed ...

More Than Black or White: Melanization and Toll Share Regulatory Serine Proteases in Drosophila

Bruno Lemaitre, Jan Paul Dudzic, Mark Austin Hanson, Igor Iatsenko

The melanization response is an important defense mechanism in arthropods. This reaction is mediated by phenoloxidases (POs), which are activated by complex extracellular serine protease (SP) cascades. Here, we investigate the role of SPs in the melanizati ...

Novel compartment-specific biosensors reveal a complementary subcellular distribution of bioactive Furin and PC7

Pierpaolo Ginefra

Proprotein Convertases (PCs) constitute a family of serine proteases that activate various hormones, growth factors and cell adhesion molecules by mediating endoproteolytic cleavage of their secreted inactive precursors during their transit in the secret ...

Calpain-mediated tau fragmentation is altered in Alzheimer's disease progression

Andrea Pfeifer, Andreas Muhs

The aggregation of intracellular tau protein is a major hallmark of Alzheimer's disease (AD). The extent and the stereotypical spread of tau pathology in the AD brain are correlated with cognitive decline during disease progression. Here we present an in-d ...
