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 va
Researchers at McGill University and the University of Pennsylvania have discovered that a widely used anti-diabetic drug can boost the immune system and increase the potency of vaccines and cancer treatments. Their findings will be published June 3 in the journal Nature.
The discovery was made by Dr. Russell Jones, an assistant professor at McGill's Goodman Cancer Centre and the Department of Physiology, Faculty of Medicine, Yongwon Choi, PhD, professor of pathology and laboratory medicine, and postdoctoral fellow Erika Pearce, PhD, of the University of Pennsylvania. They discovered that the widely prescribed diabetes treatment metformin increases the efficiency of the immune system's T-cells, which in turn makes cancer and virus-fighting vaccines more effective.
BioNTech and Pfizer are to start tests on humans of next-generation vaccines that protect against a wide variety of coronaviruses in the second half of the year.
Their experimental work on shots that go beyond the current approach include T-cell-enhancing shots, designed to primarily protect against severe disease if the
virus becomes more dangerous, and pan-coronavirus shots that protect against the broader family of viruses and its mutations.
In presentation slides posted on BioNTech's website for its investor day, the German biotech firm said its aim was to "provide durable variant protection".
The two companies are currently discussing with regulators enhanced versions of their established shot to better protect against the Omicron variant and its
sublineages.
The virus' persistent mutation into new variants that more easily evade vaccine protection, as well as waning human immune memory, have added urgency to the search
by companies, governments and health bodies for more reliable tools of protection.
As part of a push to further boost its infectious disease business, BioNTech said it was independently working on precision antibiotics that kill superbugs that
have grown resistant to currently available anti-infectives.
If you have low testosterone levels, there is a good chance you have felt some physical side effects from that. You may have heard that certain physical
activity helps combat the depletion, and there is truth in this. There is a link between increasing and fine-tuning an exercise agenda and raising testosterone
levels. Below, the relationship is explored in more detail.
WHAT DOES TESTOSTERONE DO?
There is more to the function of testosterone than just in relation to your sex drive. Of course, that is important, but it also impacts muscle building, strength,
energy levels, hair growth, and red blood cells. When levels are low, there are big consequences for anybody from hair loss to weak muscles and even exhaustion too.
TESTOSTERONE AND OBESITY
One of the biggest things that affects testosterone is being overweight. If you are carrying a few extra pounds, it would be beneficial to try to get into some
healthier habits if you want to promote an organic increase in T-levels.
HOW EXERCISE PLAYS A ROLE
Exercise seems to be a natural inhibitor of testosterone, especially when you focus on particular strategies and workout styles such as strength training. Levels
have been shown to rise immediately after exercise for anything from fifteen minutes to an hour plus. While it is different for everyone, the link is clear.
Health Some define health at the absence of illness or injury (symptoms). We define health as the body’s
ability to accurately assess and appropriately respond to the stresses it encounters. Just because you are not in
pain or don’t feel sick does not mean you are necessarily healthy. Your body might just be working around
problem areas until it eventually succumbs and begins showing symptoms. How you feel is not always the best way to
assess your health. This is the reason why dentists look for cavities; why medical doctors test blood pressure and
pulse; and why we as Chiropractors check for Vertebral Subluxations (mis- alignments or nerve interference).
Subluxations can interfere with the brain’s communication, through the nervous system, to every organ, muscle,
tissue, system, gland and cell in your body. Chiropractors use specific adjustments to restore normal joint function
and reduce the detrimental effects of subluxations, thus removing nerve interference and enabling the body to
approach its optimum health potential. Causes of Subluxations Subluxations can occur due to a combination of three
stresses on the body. These are sometimes referred to as the three T’s of subluxation. Trauma (or physical);
Toxins (or chemical); Thoughts (emotional). TRAUMA from repetitive stresses like poor posture, sports injuries or
through injuries like car accidents, place biomechanical stress on the vertebral joints and supportive tissues of the
vertebral motion segment, especially the disc. TOXINS from tobacco, alcohol, drugs, food preservatives, chemical
pesticides and additives place considerable stress on the delicate chemical balance within the body. This contributes
to the subluxation complex through a mechanism called the viscero-somatic reflex. THOUGHTS have the potential to be
the most significant and detrimental stress with regard to contributing to the subluxation complex. Emotional stress
leads to neurologica
