Personalized Immunotherapy Refined by Mass Spec-Machine Learning Pairing

Technology Networks | October 16, 2019

Ludwig Cancer Research scientists have developed a new and more accurate method to identify the molecular signs of cancer likely to be presented to helper T cells, which stimulate and orchestrate the immune response to tumors and infectious agents. The study, led by David Gfeller and Michal Bassani-Sternberg of the Lausanne Branch of the Ludwig Institute for Cancer Research, is reported in the current issue of Nature Biotechnology. The new method combines two powerful new technologies. One is a mass spectrometry technology developed by Bassani-Sternberg’s lab to rapidly and inexpensively obtain the amino acid sequences of thousands of peptide antigens—or protein fragments—bound to a molecular complex known as HLA that is expressed on the surface of cells. The other is a novel computational tool developed in Gfeller’s lab that is based on machine learning, the computational approach that powers face-recognition software, among other things. “This method advances our effort to find good targets for cancer immunotherapy,” says Bassani-Sternberg. “But it is not only important for vaccines and other immunotherapies. It is also a tool we will be using for basic science, to better understand the interaction of cancers with the immune system.”

Many human diseases have a genetic component to them. There are over 6,000 genetic disorders, many of which are fatal or severely debilitating. A genetic disease is caused by a mutation in DNA and can be divided into 4 major groups: Single-gene mutation;  Multiple genes mutations; Chromosomal changes and mitochondrial mutations. The completion of the Human Genome Project in 2003 has helped to identify genes associated with many genetic diseases. As a result, scientists were able to develop genetic testing which could confirm a diagnosis or a carrier state of the disease or predict future illness or even a response to therapy. There are currently over 2000 genetic tests available. In this infographic, we gathered information about the 10 most common genetic diseases.

Benchling | September 17, 2021

Benchling , innovator of the research and development (R&D) cloud for the biotechnology industry, today announced its entry into the early development market. The company brings new solutions to market that enable scientists for the first time to work seamlessly from research to development in a single system. By expanding the range of services, the Benchling R&D cloud is designed to offer both the flexibility and speed required for research efficiency as well as the control and conformity required for compliance with regulations. The market and society are putting unprecedented pressure on R&D companies to develop new products and get them to market faster. Vaccines typically take years to develop. But in developing COVID-19 vaccines and therapies, researchers have been able to get them ready for clinical trials in a matter of months. Faster time to market for innovative biotech products can mean that patients can receive new treatments for life-changing diseases faster, such as the COVID-19 vaccines. It can also mean producing more food with less energy, enriching consumer lives with ethically sourced products, and making businesses more climate-friendly. The development of such complex, important products requires modern technologies. Different individual solutions for electronic laboratory notebooks (ELN), laboratory information management systems (LIMS) and laboratory execution systems (LES) form silos that exacerbate the challenges of complex collaboration. They force scientists to spend time comparing data between different systems instead of gaining important insights that accelerate product development. With more than 600 customers spanning a wide range of company sizes, industries and scientific use cases, Benchling relies on customer partnerships to expand its product range. Here are examples of benchling customers who have improved their development speed, scientific knowledge and collaboration within their R&D organizations: Syngenta is one of the world's largest producers of novel seeds. Worldwide, 35 percent of food is rendered unusable by pests and diseases. New biological solutions and better built-in defense mechanisms not only protect against food waste, but also reduce the need for harmful chemicals that pollute the environment. Syngenta's work relies on scaling, as our researchers: internally test hundreds of thousands of seeds in a variety of growing environments. When we discover viable varieties that meet the needs of farmers, we need to replenish our seed stocks quickly for testing in laboratories, greenhouses and field trials around the world,“Thanks to benchling, we said goodbye to paper. Our global seed R&D teams can efficiently work together on a single platform to standardize the development of seed varieties from the laboratory to the test field. This has enabled us to restructure much of our work and accelerate the time-to-market for new seed products. - Charlie Baxter, Head of Traits, Regulatory and Product Safety at Syngenta. New workflows: Benchling has expanded the workflows application to support collaboration between specialized R&D teams. Users can now coordinate tasks and processes across teams with full traceability, including methods, samples and inventory. Project managers gain insight into ongoing processes in order to reduce bottlenecks and increase productivity. Workflows help teams from research to development to work together more efficiently and to reach important milestones more quickly. Structured Templates: With Benchling's new, more structured templates, product development teams can easily create common, standardized processes for repeatable experiments, analytical tests, QC protocols and more. These procedures can be regulated in a targeted manner in order to meet compliance requirements. Validated cloud: At the beginning of 2021, Benchling switched to a validated cloud in order to be able to provide the platform for customers in a GxP environment. About Benchling Benchling is the pioneer for the R&D cloud, software that supports the biotechnology industry. Globally, more than 200,000 scientists in over 600 companies and 7,000 research institutions use Benchling's R&D cloud to make groundbreaking discoveries and bring the next generation of drugs, food and materials to market faster than ever before.

Kaneka Eurogentec Announces the Successful Production of 25g of mRNA in One Batch

Kaneka Eurogentec | February 23, 2022

Kaneka Eurogentec, an FDA inspected contract development and manufacturing organization announced today that its mRNA manufacturing facility has successfully produced a 25 g batch of mRNA for a US customer. Eurogentec’s GMP mRNA manufacturing service offers in vitro transcription (IVT), purification, quality control and batch release of GMP material up to 25 g scale in its current facility in Belgium. In this project Eurogentec successfully produced and purified 25 g of material in one batch that will be tested by the customer. This quantity is equivalent to 100,000’s to millions of doses of mRNA, potentially sufficient for late clinical and commercial uses. Ingrid Dheur, Vice President Biopharma Development at Kaneka Eurogentec stated, “This successful production confirms our ability to produce mRNA at large scale and with a quantity and purity level that exceeds the targets requested by the customer.” “The rapid growth in cell and gene therapy products is driving the need for plasmid DNA and mRNA production. Our existing pharma and biotech customers have already expressed the need for such large-scale manufacturing capabilities, and we have developed methods to respond to these needs. Additionally, we are currently in the planning stages for a 2nd manufacturing facility to further expand our GMP mRNA manufacturing offering”. Lieven Janssens, President and CEO at Kaneka Eurogentec About mRNA Messenger RNA (mRNA) is a molecule that encodes for a protein which will have a beneficial effect in patients. Rather than producing complex proteins, producing mRNA is a convenient way to deliver the protein as a precursor. The production of mRNA is much simpler than producing a recombinant protein and thus mRNA molecules have the advantage of enabling a shorter production time to clinic. For example, current mainstream therapies for the protection against COV-SARS-2 infections are based on mRNA and have been developed in record time. The success of these COVID-19 mRNA vaccines has opened the evaluation of mRNA for other infectious diseases, for example influenza or HIV, and the need for custom large-scale production of GMP mRNA.
