Using unnatural sugars to target galectins

The GibsonGroup, as part of a large BBSRC/Innovate funded collaboration have published their latest results into using nanomaterials to probe glycan-binding events. In this collaborative work, a combined chemical and enzymatic synthetic route was exploited to generate glycans which could be attached to nanoparticles for glycan/lectin screening - a platform technology developed by the GibsonGroup. Using this approach, it was shown that selective addition of fluorine atoms allow selective binding of galectins which is not possible using natural disaccharides, and may offer a route for targeting therapies and diagnostics. https://doi.org/10.1039/D0SC05360K

Modelling of SARS-CoV-2 reinfection frequency

One of the key questions in predicting the course of the COVID-19 pandemic is how well and for how long the immune response to the virus protects people from reinfection. The Robb group modelled early SARS-CoV-2 infection and fatality data from different regions around the world to predict how many reinfection cases would be expected if there was no immunity to the disease. Numerous serological studies now support the conclusion that short-term immunity to the virus exists. doi:10.2196/21168

New diagnostic test detects and identifies SARS-CoV-2 virus in less than five minutes

Scientists, led by Dr Nicole Robb, have developed an extremely rapid diagnostic test that detects and identifies viruses in less than five minutes. The test uses artificial intelligence to distinguish between microscope images of fluorescent viruses in throat swab samples. Unlike other technologies that detect a delayed antibody response or that require time-consuming sample preparation such as viral lysis or amplification, the new test quickly detects intact virus particles; meaning the assay is simple, fast and has the potential to be carried out in non-laboratory conditions.

Modulating Immune Cells using GlycoMaterials

The GibsonGroup have collaborated with immunologists at Nottingham to develop immune-instructive materials. Using the GibsonGroups technology for immobilising glycans (sugars) onto surfaces, they were able to screen for specific mixtures of glycans which modulated the behaviour of dendritic cells - key components of our immune system. This work shows that the incorporation of synthetic glycomaterials could be useful for the development of advanced implantable materials or in regenerative medicine. Read about the research here

Cryopreserving proteins with polymers

Proteins are used as medicines, catalysts and many other application areas, but require careful storage conditions. Cryopreservation (freezing) is a widely used method to bank proteins but it is often necessary to add solvents (or other excipients) to protect them. The GibsonGroup have published an investigation into using polymers which control ice crystal growth, to protect proteins during freezing, which are now being investigated to help store and transport protein therapies. https://doi.org/10.1016/j.eurpolymj.2020.110036

Warwick Medical School spinout - NanoSyrinx

NanoSyrinx is the first company to engineer ‘nanosyringes’, a selective non-viral peptide and protein delivery system identified in an undisclosed organism. The company will focus on direct cytosolic delivery of genome editing enzymes and therapeutic proteins in vivo, with key applications in the cell and gene therapy space.

CEO Dr Joe Healey, who joined from the Waterfield Lab to lead the company, said, “We believe that our nanosyringe platform will unlock new approaches for the treatment of many intractable diseases and will be of value to a wide range of potential partners and customers. The company is delighted with the early progress made in both in vivo active pharmaceutical delivery and ex vivo cell engineering applications.”

Dr Nick Waterfield commented, “We are pleased with the traction the company has made, with both academics and industry leaders across a range of applications. In particular, our academic collaborations have provided excellent opportunities for us to build out a synthetic biology platform and validate compatibility with a range of payloads, including pro-apoptotic peptides, reporter proteins, and larger functional proteins (such as DNA modifying enzymes and toxins). We will also be exploring a diverse range of other payloads. The team would welcome discussions with the right partners as we move to the next phase“.

NanoSyrinx’s initial focus will be on the development of its ex vivo gene editing nanosyringe concept, having already engaged with a number of leaders in the cell therapy field.

Rapid low cost SARS-COV-2 diagnostics using glycosylated nanoparticles

Current diagnostic strategies for SARS-COV-2 rely on centralised infrastructure using PCR (polymerase chain reaction) methods. The GibsonGroup have discovered that the SARS-COV-2 spike protein binds a sialic acids (a type of glycan other respiratory viruses also target) and show this can be used to detect it. The glycan is installed onto gold nanoparticles, which are then used in a hijacked ‘pregnancy test’ allowing quick detection without any infrastructure. This publication proves the principle including detection of a model virus system. https://doi.org/10.1021/acscentsci.0c00855

Improved method to prepare glycosylated nanoparticles

Glycans (aka sugars) are crucial in infection and cell-cell signalling, but the incorporation of complex glycans into nanomaterials is not always easy. The GibsonGroup have developed a method to enable direct capture of glycans onto nanoparticles, removing complex chemical-synthesis steps which will enable the rapid investigation of their use in diagnostics, in particular. https://doi.org/10.1021/acs.bioconjchem.0c00465

Replacing solvents with polymers to cryopreserve stem cells

The GibsonGroup report the use of their (patent pending) macromolecular cryoprotectants for the cryopreservation of stem (stromal) cells. With this technology the amount of DMSO was reduced required for cryopreservation was reduced from 10 wt % to just 2.5 wt %. These findings are important for regenerative medicine applications where high-quality frozen cells are crucial, and the reduced DMSO may reduce toxicity and improve stem cell manufacturing processes.

X-ray Diffraction to Probe the Kinetics of Ice Recrystallization Inhibition

The Gibson Group are developing mimetics of anitfreeze proteins for various biomedical applications. In this work, they explore the use of X-ray scattering as a tool to help discover new materials and understand existing antifreeze proteins. Traditional tests of antifreeze function use microscopy and end-point assays, or require extensive image analysis of a relatively small number of crystals. Here, low-temperature x-ray scattering was used (with superb assistance from the X-Ray RTP at Warwick) to enable real-time profiling of ice growth rates, probing 100’s of crystals simultaneously. This work will help develop new more active antifreeze protein mimetics for biomedical and biotechnological applications. https://doi.org/10.1039/C9AN02141H

Ice Recrystallisation Inhibiting Polymer Nano-Objects via Saline-Tolerant Polymerisation-Induced Self-Assembly

The Gibson Group have developed new nanoparticles capable of inhibiting ice growth, to mimic antifreeze proteins. Antifreeze proteins often show size-dependant activity - larger proteins are more active than small. In this work, the Gibsongroup used the tool of polymerization induced self assembly, PISA. PISA is a powerful, but typically cannot be conducted in saline, which can limit its application, especially for ice growth assays which require saline. The team developed an easy method to enable saline-stable PISA and exploited this to generate nanoparticles which were potent ice growth inhibitors, and were more active than the starting polymers. https://doi.org/10.1039/D0MH00354A

Polymer-Stabilized Sialylated Nanoparticles: Synthesis, Optimization, and Differential Binding to Influenza Hemagglutinins

The Gibson Group has explored the use of gold nanoparticles as a tool to probe how influenza targets our cells. Influenza engages cells in our respiratory tracts by binding to glycans (sugars) and the pattern of sugars they bind is a key part of zoonosis - species hopping, for example avian to human influenza. The GibsonGroup used their polymer-stabilised nanoparticle technology to capture glycans onto the nanoparticles and probed how they interact with a components from a panel of influenza strains. This revealed key differences in the binding pattern compared to just using the glycans alone.
