Chronic delivery of antibody fragments using immunoisolated cell implants as a passive vaccination tool

Belaunzaran, Osiris Marroquin ; Cordero, Maria Isabel ; Setola, Veronica ; Bianchi, Siro ; Galli, Carmela ; Bouche, Nicolas ; Mlynarik, Vladimir ; Gruetter, Rolf ; Sandi, Carmen ; Bensadoun, Jean-Charles ; Molinari, Maurizio ; Aebischer, Patrick

Background: Monoclonal antibodies and antibody fragments are powerful biotherapeutics for various debilitating diseases. However, high production costs, functional limitations such as inadequate pharmacokinetics and tissue accessibility are the current principal disadvantages for broadening their use in clinic. Methodology and Principal Findings: We report a novel method for the long-term ...

A bispecific immunotweezer prevents soluble PrP oligomers and abolishes prion toxicity

Bardelli, Marco ; Frontzek, Karl ; Simonelli, Luca ; Hornemann, Simone ; Pedotti, Mattia ; Mazzola, Federica ; Carta, Manfredi ; Eckhardt, Valeria ; D’Antuono, Rocco ; Virgilio, Tommaso ; González, Santiago F. ; Aguzzi, Adriano ; Varani, Luca

Antibodies to the prion protein, PrP, represent a promising therapeutic approach against prion diseases but the neurotoxicity of certain anti-PrP antibodies has caused concern. Here we describe scPOM-bi, a bispecific antibody designed to function as a molecular prion tweezer. scPOM-bi combines the complementarity-determining regions of the neurotoxic antibody POM1 and the neuroprotective...

The protein disulfide isomerase ERp57 regulates the steady-state levels of the prion protein

Torres, Mauricio ; Medinas,Danilo B. ; Matamala, José Manuel ; Woehlbier, Ute ; Cornejo, Víctor Hugo ; Solda, Tatiana ; Andreu, Catherine ; Rozas, Pablo ; Matus, Soledad ; Muñoz, Natalia ; Vergara, Carmen ; Cartier, Luis ; Soto, Claudio ; Molinari, Maurizio ; Hetz, Claudio

Although the accumulation of a misfolded and protease-resistant form of the prion protein (PrP) is a key event in Prion pathogenesis, the cellular factors involved in its folding and quality control are poorly understood. PrP is a glycosylated and disulfide-bonded protein synthesized at the endoplasmic reticulum (ER). The ER foldase ERp57 (also known as Grp58) is highly expressed in the brain...
