Article | July 20, 2022

Biopharmaceutical innovations are among the most ingenious and refined achievements of modern medical science. New concepts, techniques, and therapies are emerging, such as the cell therapy Provenge, which can be used to treat cancer, and gene therapies, which provide even more amazing promises of disease remission and regenerative medicine. In addition, the COVID-19 pandemic has caused a huge boom in the pharmaceutical industry. This is because more and more attention is being paid to increasing manufacturing capacity and starting new research on drug development. Biopharma: Leading the Way in the Pharma Sector In the past couple of years, the biopharmaceutical sector has deepened its roots across the medical and pharmaceutical industries, on account of the transformation of pharmaceutical companies towards biotechnology, creating opportunities for growth. Also, growing advancements in technologies such as 3D bioprinting, biosensors, and gene editing, along with the integration of advanced artificial intelligence and virtual and augmented reality are estimated to further create prospects for growth. According to a study, the biopharmaceutical sector makes nearly $163 billion around the world and grows by more than 8% each year, which is twice as fast as the traditional pharma sector. Massive Investments Directed Towards Biopharma Investing in biotech research and development (R&D) has yielded better returns than the pharma industry average. Hence, a number of pharmaceutical companies are shifting their presence toward biopharma to capitalize on the upcoming opportunities by investing in and expanding their biotechnology infrastructure.

Better Purification and Recovery in Bioprocessing

Article | July 11, 2022

In the downstream portion of any bioprocess, one must pick through the dross before one can seize the gold the biotherapeutic that the bioprocess was always meant to generate. Unfortunately, the dross is both voluminous and various. And the biotherapeutic gold, unlike real gold, is corruptible. That is, it can suffer structural damage and activity loss. When discarding the dross and collecting the gold, bioprocessors must be efficient and gentle. They must, to the extent possible, eliminate contaminants and organic debris while ensuring that biotherapeutics avoid aggregation-inducing stresses and retain their integrity during purification and recovery. Anything less compromises purity and reduces yield. To purify and recover biotherapeutics efficiently and gently, bioprocessors must avail themselves of the most appropriate tools and techniques. Here, we talk with several experts about which tools and techniques can help bioprocessors overcome persistent challenges. Some of these experts also touch on new approaches that can help bioprocessors address emerging challenges.

Next-Gen Gene Therapy to Counter Complex Diseases

Article | July 13, 2022

Gene therapy has historically been used to treat disorders with in-depth knowledge caused by a single genetic mutation. Thanks to the introduction of new generation technologies, the potential of gene therapy is expanding tAo treat diseases that were previously untreatable. Evolution of Gene Therapy One of the major success stories of the twenty-first century has been gene therapy. However, it has not been the same in the past. The field's journey to this point has been long and mostly difficult, with both tragedy and triumph along the way. Initially, genetic disorders were thought to be untreatable and permanently carved into the genomes of individuals unfortunate enough to be born with them. But due to the constant technological advancement and research activities, gene therapy now has the potential to treat various genetic mutation-causing diseases with its ability to insert a new copy and replace faulty genes. Gene Therapy is Finding New Roads in the Medical Sector Gene therapy can help researchers treat a variety of conditions that fall under the general heading of epilepsy, instead of only focusing on a particular kind of disorder brought on by a genetic mutation. Following are some of the domains transformed by gene therapy. Neurology – Gene therapy can be used for the treatment of seizures by directly injecting it into the area causing an uncontrolled electrical disturbance in the brain. Furthermore, by using DNA sequences known as promoters, gene therapy can be restricted to specific neurons within that area. Ophthalmology – Genetic conditions such as blindness can be caused due to the mutation of any gene out of over 200 and resulting in progressive vision loss in children. With advanced gene therapies such as optogenetics, lost photoreceptor function can be transferred to the retinal cells, which are responsible for relaying visual information to the brain. This might give patients the ability to navigate in an unknown environment with a certain level of autonomy. The Future of Gene Therapy The news surrounding gene therapy has been largely favorable over the past few years, with treatment after treatment obtaining regulatory approvals, successful clinical trials, and garnering significant funds to begin development. With more than 1,000 clinical trials presently underway, the long-awaited gene therapy revolution might finally be here.

Novel peptide could lead to antibiotic for drug-resistant bacteria

Drug Target Review | November 22, 2019

An international team of researchers has discovered a novel peptide that attacks gram negative bacteria at a previously unknown site of action. Germs such as Escherichia coli and Klebsiella pneumoniae have become resistant to the most – and in some cases all – currently available antibiotics. Their additional external membrane makes these difficult to attack as it protects the bacteria by preventing many substances from getting into the cell interior. Especially for the treatment of diseases caused by these so-called gram negative bacteria, there is a lack of new active substances. “Since the 1960s, scientists have not succeeded in developing a new class of antibiotics effective against gram negative bacteria, but this could now be possible with the help of this peptide,” said Professor Till Schäberle from the Institute of Insect Biotechnology at Justus Liebig University Giessen (JLU) and project leader at the DZIF, whose research group was involved in the discovery.

Gut Bacteria May Impact Aging

Technology Networks | November 19, 2019

An international research team led by Nanyang Technological University, Singapore (NTU Singapore) has found that microorganisms living in the gut may alter the ageing process, which could lead to the development of food-based treatment to slow it down. All living organisms, including human beings, coexist with a myriad of microbial species living in and on them, and research conducted over the last 20 years has established their important role in nutrition, physiology, metabolism and behaviour. Using mice, the team led by Professor Sven Pettersson from the NTU Lee Kong Chian School of Medicine, transplanted gut microbes from old mice (24 months old) into young, germ-free mice (6 weeks old). After eight weeks, the young mice had increased intestinal growth and production of neurons in the brain, known as neurogenesis. The team showed that the increased neurogenesis was due to an enrichment of gut microbes that produce a specific short chain fatty acid, called butyrate. Butyrate is produced through microbial fermentation of dietary fibres in the lower intestinal tract and stimulates production of a pro-longevity hormone called FGF21, which plays an important role in regulating the body’s energy and metabolism. As we age, butyrate production is reduced.

Having a Certain Type of Bacteria in Your Guts May Increase Risk of Developing Bowel Cancer

Technology Networks | November 04, 2019

In the first study to use a technique called Mendelian randomization to investigate the causal role played by bacteria in the development of bowel cancer, Dr Kaitlin Wade, from the University of Bristol, told the 2019 NCRI Cancer Conference: “We found evidence that the presence of an unclassified type of bacteria from a bacterial group called Bacteroidales increased the risk of bowel cancer by between 2-15%. “This means that, on average, people with this type of bacteria within their gut may have a slightly higher risk of bowel cancer compared to those who don’t. We were able to use Mendelian randomization to understand the causal role that these bacteria may have on the disease. Our findings support previous studies that have shown that Bacteroidales bacteria are more likely to be present, and in larger quantities, in individuals with bowel cancer compared to those without the disease.” The microbiome is a community of microorganisms, bacteria in this case, that occur naturally in the body. There is increasing evidence that the make-up of the microbiome plays a role in the human health and the body’s susceptibility to disease. The human gut microbiome, which contains approximately three trillion bacteria, aids digestion and provides protection against infections. It is determined by a person’s individual genetic makeup and their environment, so is unique to each person. It also remains relatively stable across a person’s life, unless it is affected by antibiotics, an illness or a change of diet, among other things.
