The role of the NF-kappaB pathway in Amyotrophic lateral sclerosis pathogenesis

Emma Charlotta Källstig

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative motor disorder, which results in death within a few years of diagnosis. While the cause of most cases of ALS is unknown, 10% of cases are familial (fALS), and associated with mutations in one of ov ...

Molecular analysis and therapeutic applications of human serum albumin-fatty acid interactions

Alessandro Zorzi, Alessandro Angelini

Human serum albumin (hSA) is the major carrier protein for fatty acids (FAs) in plasma. Its ability to bind multiple FA moieties with moderate to high affinity has inspired the use of FA conjugation as a safe and natural platform to generate long-lasting t ...

Engineering of chitosan-based derivatives for non-viral gene delivery

Laura Camille Louise Nicolle

Gene therapy offers the possibility to treat or even cure diseases originating from genetic defects by introducing a therapeutic gene in target cells or correcting the initial defective gene. Amongst different options, non-viral vectors rely on the deliver ...

Efficient viral transduction in mouse inner ear hair cells with utricle injection and AAV9-PHP.B

Bernard Schneider, Paola Andrea Solanes Vega

Viral delivery of exogenous coding sequences into the inner ear has the potential for therapeutic benefit for patients suffering genetic or acquired hearing loss. To devise improved strategies for viral delivery, we investigated two injection techniques, r ...

Modified cyclodextrins as broad-spectrum antivirals

Francesco Stellacci, Natalia Gasilova, Daniel Ortiz Trujillo, Matteo Gasbarri, Valeria Cagno, Samuel Thomas Jones, Matej Janecek

Viral infections kill millions of people and new antivirals are needed. Nontoxic drugs that irreversibly inhibit viruses (virucidal) are postulated to be ideal. Unfortunately, all virucidal molecules described to date are cytotoxic. We recently developed n ...

Influenza A viruses use multivalent sialic acid clusters for cell binding and receptor activation

Suliana Manley, Christian Sieben

Influenza A virus (IAV) binds its host cell using the major viral surface protein hemagglutinin (HA). HA recognizes sialic acid, a plasma membrane glycan that functions as the specific primary attachment factor (AF). Since sialic acid alone cannot fulfill ...

A ligand-based system for receptor-specific delivery of proteins

Kai Johnsson, Luc Reymond

Gene delivery using vector or viral-based methods is often limited by technical and safety barriers. A promising alternative that circumvents these shortcomings is the direct delivery of proteins into cells. Here we introduce a non-viral, ligand-mediated p ...

Determinants of HIV-1 reservoir size and long-term dynamics during suppressive ART

Jacques Fellay, Christian Axel Wandall Thorball, Alessandro Borghesi

The HIV-1 reservoir is the major hurdle to a cure. We here evaluate viral and host characteristics associated with reservoir size and long-term dynamics in 1,057 individuals on suppressive antiretroviral therapy for a median of 5.4 years. At the population ...

Amphiphilic nanoparticle delivery enhances the anticancer efficacy of a TLR7 ligand via local immune activation

Francesco Stellacci, Ahmet Bekdemir

Although immunotherapy shows great promise for the long-term control of cancer, many tumors still fail to respond to treatment. To improve the outcome, the delivery of immunostimulants to the lymph nodes draining the tumor, where the antitumor immune respo ...

Transfer of enteric viruses (adenovirus and coxsackievirus) and bacteriophage (MS2) from liquid to human skin

Tamar Kohn, Timothy R. Julian, Ana Karina Pitol Garcia, Heather Nicole Bischel-Magnan

Indirect exposure to waterborne viruses increases risk of infection, especially amongst children with frequent hand-to-mouth contacts. Here, we quantified the transfer of one bacteriophage (MS2) and two enteric viruses (adenovirus and coxsackievirus) from ...

AAV based gene therapy for rare diseases : targeting astrocytes for functional recovery in Amyotrophic Lateral Sclerosis

Cylia Cloé Rochat

Of the seven thousand diseases that are described as rare, 80% of them have an identified genetic cause. With this in the mind, the development of technologies, such as gene therapy, to address the genetic factors involved in these pathologies, might be a ...

Encapsulated Cellular Implants for Recombinant Protein Delivery and Therapeutic Modulation of the Immune System

Bernard Schneider, Aurélien Lathuilière

Ex vivo gene therapy using retrievable encapsulated cellular implants is an effective strategy for the local and/or chronic delivery of therapeutic proteins. In particular, it is considered an innovative approach to modulate the activity of the immune syst ...
