Pharmaceutical giant AstraZeneca will acquire biotechnology company Neogene Therapeutics for up to $320 million, the London-listed drugmaker said on Tuesday (November 29) as it seeks to build its pipeline of cell-based cancer treatments. Though AstraZeneca's oncology portfolio accounted for more than a third of the company's revenue last year, it does not have an approved cell-based cancer therapy and is behind rivals such as Novartis and Gilead. "Neogene's leading (T-cell receptor) discovery capabilities and extensive manufacturing experience complement the cell therapy capability we have built over the last three years," said Susan Galbraith, AstraZeneca's executive vice president of oncology research. Cell-based treatments are a relatively new approach to treating cancer, most of which involve drawing the body's own immune cells and processing them in the lab to target and kill cancer cells. Neogene's approach goes one step further in that its experimental T-cell receptor therapies seek to target DNA mutations specific to tumours, not only certain proteins on the surface of cancer cells.

Immunogenicity refers to the capacity of a vaccine to provoke an immune response in the body. An effective immune response is characterized by the production of specific antibodies, activation of immune cells, and the development of immunological memory. The goal is to elicit a durable and robust response that can prevent or control infections. Leveraging Viral Vector Technology Viral vectors serve as essential vehicles for delivering antigenic proteins or genetic material into target cells, triggering an immune response. Biotechnology companies have been exploring advanced strategies to optimize viral vector design, aiming to enhance immunogenicity and improve vaccine effectiveness. Vector Selection: The choice of viral vector plays a crucial role in determining immunogenicity. Different viruses have unique properties and characteristics that can impact immune responses. Biotechnology companies meticulously select viral vectors that possess the desired attributes, such as the ability to infect target cells efficiently and induce strong immune responses. Genetic Engineering: Advanced genetic engineering techniques are employed to modify viral vectors, tailoring them to specific vaccine requirements. By introducing specific antigenic proteins or genetic material, researchers can stimulate the immune system to mount a targeted response. This precise manipulation enhances the vaccine's ability to elicit a robust immune reaction. Immunomodulatory Elements: Biotechnology companies are incorporating immunomodulatory elements into viral vector designs. These elements can enhance the immune response by stimulating various components of the immune system, such as antigen-presenting cells and T cells. By activating and priming these immune cells, the vaccine can generate a more potent and sustained immune response. Adjuvants: Adjuvants are substances added to vaccines to enhance their immunogenicity. They stimulate and amplify the immune response, improving the

The UK's National Health Service (NHS) has become the first healthcare system in the world to provide a new blood group genotyping test for people with rare inherited blood disorders. From Monday (22 January), thousands of patients suffering from sickle cell disorder and thalassaemia will get access to the world-first 'blood matching' genetic test, which will help reduce their risk of transfusion side effects while offering more personalised care. In England, it is estimated that around 17,000 people are living with sickle cell disorder, with 250 new cases reported each year, and there are about 800 thalassaemia patients, with less than 50 new cases a year. Health Minister Andrea Leadsom said: "Thousands of people living with sickle cell disease and thalassaemia will be eligible for this new world-first blood test which is set to transform their care.

Origin of life has always been a mystery to the man-kind, which further raised a query on how a single-cell turned out to be multi-celled organism.

Starts in the bone marrow most blood cancers are also called hematologic cancers. When the abnormal blood cells start growing out of control, interrupting the function of normal blood cells, which fight off infection and produce new blood cells then the condition, is called blood cancer.

The National Institute for Health and Care Excellence (NICE) has recommended pembrolizumab in combination with chemotherapy (paclitaxel or nab-paclitaxel) which is said to benefit people with triple negative breast cancer. Clinical trial evidence shows that, compared with paclitaxel, pembrolizumab combination increases how long people have before their cancer gets worse and how long they live. NICE already recommends atezolizumab in combination with chemotherapy for untreated PD-L1-positive, locally advanced or metastatic, triple-negative breast cancer. Atezolizumab combination is recommended by NICE for people with IC equal to or greater than 1%. "This means that some people who can't have atezolizumab combination could be eligible for pembrolizumab combination," said NICE. NICE's independent appraisal committee also agreed that the pembrolizumab combination meets the higher cost-effectiveness threshold for life-extending treatments for people with a short life expectancy. Given by injection every 3 weeks, pembrolizumab (also called Keytruda and made by Merck Sharp and Dohme) is a type of immunotherapy that specifically targets triple negative breast cancer. It works by blocking the activity of a protein known as PD-L1 which is produced in larger amounts on cancerous cells than normal cells. By blocking PD-L1 it helps the person's own immune cells to attack the cancer.

A group of drugs commonly used to treat erectile dysfunction may be able to boost the effect of chemotherapy in oesophageal cancer, according to new research funded by Cancer Research UK and the Medical Research Council. The research, published on Tuesday (June 22) in Cell Reports Medicine, found that the drugs, known as PDE5 inhibitors can reverse chemotherapy resistance by targeting cells called cancer-associated fibroblasts (CAFs) residing in the area surrounding the tumour. Although this is early discovery research, PDE5 inhibitors combined with chemotherapy, may be able to shrink some oesophageal tumours more than chemotherapy could alone, tackling chemotherapy resistance, which is one of the major challenges in treating oesophageal cancer. Oesophageal cancer affects the food pipe that connects the mouth to the stomach, and while it is a relatively rare cancer, the UK has one of the higher rates in the world, with 9,300 new oesophageal cancer cases in the UK every year. Resistance to chemotherapy in oesophageal cancer is influenced by the tumour microenvironment, the area that sounds the tumour. This is made up of molecules, blood vessels, and cells such as cancer associated fibroblasts (CAFs), which are important for tumour growth. It feeds the tumour and can act as a protective cloak, preventing treatments like chemotherapy from having an effect.

WHAT IS PROTEINASE K MADE OF? Proteinase K is known enzyme belonging to the class of serine proteases that cleave adjacent to the carboxylic group peptide bonds of aromatic and aliphatic amino acids. It's also exhibited a very broad cleavage specificity. The enzyme was discovered in extracts of the fungus Engyodontium album. HOW DOES PROTEINASE K WORK? In molecular biology, main application of proteinase K is to digest proteins during nucleic acids purification in order to remove protein contaminants: - Proteinase K quickly inactivates nucleases (enzymes that digest nucleic acids) that degrade DNA or RNA molecules during the cleansing. - Proteinase K is activated by calcium. It does not affect the activity of the proteinase, but protects again autolysis, improves thermal stability, and regulates substrate binding capacity. To increase the stability of Proteinase K, thereby enhancing its action, Urea as well as SDS (sodium dodecyl sulfate) or elevated temperature at 37-60C is commonly used. Inactivation of Proteinase K is occurring at temperature above 65C. WHAT IS THE PURPOSE OF PROTEINASES? Proteinase K is used to break down proteins in cell lysates (tissues, cell culture cells) and to release nucleic acids due to its action described above. Proteinase K application purpose: DNA isolation from various tissues; Removal of DNAses and RNAses: Proteinase K and RNases can act together in the lysis buffer to degrades contaminating RNAs and proteins;

The Medicines and Healthcare Products Regulatory Agency (MHRA) has authorised an innovative and first-of-its-kind gene-editing treatment for sickle-cell disease and transfusion-dependent β-thalassemia. Known as Casgevy (exagamglogene autotemcel), the treatment is based on the innovative gene-editing tool CRISPR, for which its inventors were awarded the Nobel Prize in 2020. Casgevy is the first medicine to be licensed that uses CRISPR, and it is to be used for treating patients aged 12 and over. To date, a bone marrow transplant has been the only permanent treatment option for these life-long conditions, which in some cases can be fatal. The MHRA's authorisation came after a rigorous assessment of its safety, quality and effectiveness.

Aplastic Anemia is a rare but serious disease of the blood cells. It is diagnosed by the inability of the bone marrow to synthesize RBCs, WBCs and platelets. The spongy bone marrow contains stem cells that are actively involved in Hematopoiesis.

AstraZeneca said on Thursday (June 30) that a combination of its cancer drug, Imfinzi, and chemotherapy showed promise in a late-stage trial in patients with an aggressive form of lung cancer, when given before surgery. Data showed the combination was more effective in removing cancer cells in tissue samples taken during surgery when compared with just chemotherapy in patients with non-small cell lung cancer, the drugmaker said. The interim result is a boost to the company's oncology efforts - a major area of focus - following disappointing data for Imfinzi earlier in the year in another area of therapy. AstraZeneca added the trial would continue as planned to assess the additional main goal of event-free survival, and the interim data would be shared with health authorities globally. Imfinzi belongs to the immunotherapy class of treatments, which boost the body's defences to fight cancer by using antibodies that block or bind to foreign substances in the body. The treatment generated $2.41 billion in 2021 sales.

The new deal struck by the NHS will enable provision of a life-saving treatment for babies and young children who suffer with a rare and fatal genetic disease, metachromatic leukodystrophy (MLD). The revolutionary gene therapy treatment, known by its brand name Libmeldy, is used to treat MLD, which causes severe damage to the child's nervous system and organs, leading to a life expectancy of just five to eight years. Having a reported list price of more than £2.8 million, it is the most expensive drug in the world, but can now be offered to young patients on the NHS in England after the health service negotiated a significant confidential discount. the drug works by removing the patient's stem cells and replacing the faulty gene that causes MLD before then re-injecting the treated cells into the patient. The most common form of MLD usually develops in babies younger than 30 months and can cause loss of sight, speech and hearing, as well as difficulty moving, brain impairment, seizures, and eventually death.

NICE has recommended use of tucatinib as an option to treat HER2-positive breast cancer that has spread in people who have already tried 2 or more anti-HER2 treatments. The move is set to benefit around 400 people with advanced breast cancer. Tucatinib works by blocking a specific area of the HER2 gene in cancer cells, which stops the cells from growing and spreading. The medicine is taken as two 150 mg tablets twice daily along with anti-cancer medicines trastuzumab and capecitabine. Helen Knight, programme director in the NICE Centre for Health Technology Evaluation, said: "Unfortunately there is no cure for breast cancer that has spread to other parts of the body. There is also a lack of additional anti‑HER2 treatments which can postpone the need for chemotherapy, especially for people whose cancer has spread to their brain because their treatment options are even more limited.

According to Alzheimer's Disease International, more than 55 million people worldwide will have Alzheimer's disease by 2020. This figure will nearly double every 20 years, reaching 78 million in 2030 and 139 million in 2050. The WHO Global Status Report for 2021 estimated the yearly global cost of dementia to be more than USD 1.3 trillion, with a projected increase to USD 2.8 trillion by 2030. To date most drugs developed to treat Alzheimer's disease have failed, largely because they target wrong biomarkers and individuals already exhibiting signs of the disease. Once symptoms appear, however, many brain cells responsible for memory and cognition are likely already damaged and beyond repair. Professor Shai Rahimipour in the Chemistry Department at Bar-Ilan University in Israel has pioneered a different approach utilizing theranostics to pinpoint and treat the earliest, pre-symptomatic signs of Alzheimer's disease. Showing promise in stopping progression of the disease before onset of irreversible brain cell damage, Rahimipour's groundbreaking approach has garnered significant attention in the scientific world.
