The Novo Nordisk Foundation has committed $260m to establish a new state-of-the-art research and vaccine development initiative to help combat deadly airborne infections. Airborne diseases, such as COVID-19, chickenpox and respiratory syncytial virus, occur when bacteria or viruses are transmitted through small respiratory droplets.
The technology of gene therapy is possible due to extensive DNA research and our resulting understanding of many diseases on the genetic level, and it encompasses several mechanisms such as introducing new genes (gene addition) and inactivating or replacing mutated genes (gene editing).
Macrophages are white blood cells that specialize in the detection, phagocytosis and destruction of bacteria and other harmful organisms. In other words, when fighting bacteria, the macrophages are programmed to be pro-inflammatory. However, when they are programmed to be anti-inflammatory, they can help decrease inflammation.
Valneva has said it plans to accelerate research into its Lyme disease vaccine candidate VLA15, bringing forward a trial including children into the first quarter of 2021. OspA is one of the most dominant surface proteins expressed by the bacteria when present in the ticks that spread the disease.
Merck has scored US Food and Drug Administration (FDA) approval for its next-generation pneumonia vaccine Vaxneuvance that covers 15 different strains of the pneumococcal bacteria that causes the infection. Both next-gen shots offer enhanced protection against bacteria that can cause pneumonia, blood infections and meningitis.
Researchers at KU Leuven in Belgium have found a potential mechanism underlying irritable bowel syndrome (IBS) that involves activation of immune cells primed by past gastrointestinal infections. The research findings were published in the journal Nature. Related: Monitoring Patients with IBS or Kidney Failure?
The key component in all vaccines is one or more active ingredients made from viruses or bacteria, also called antigens, which generates an immuneresponse. To further understand the key themes and technologies disrupting the pharmaceutical industry, access GlobalData’s latest thematic research report on Pharmaceutical.
12, 2020 — Lung cancer patients who harbor certain bacteria in the airways may have a poorer prognosis, a new study finds, adding to evidence that the body’s “microbiome” may play a role in cancer patients’ outlook. None of that proves the bacteria, themselves, were to blame, Segal said. THURSDAY, Nov.
New research published in Arthritis & Rheumatology suggests that immuneresponses to certain bacteria that cause periodontal disease may play a role in patients’ higher cardiovascular disease risk. Among 197 patients with rheumatoid arthritis, those with antibody responses to common […].
Researchers at Stanford Medicine found that COVID-19 antibodies preferentially target different parts of the SARS-CoV-2 virus in mild COVID-19 cases than they do in severe cases. Antibody responses are not likely to be the sole determinant of someone’s outcome,” said Scott Boyd, associate professor of pathology at Stanford.
PubMed cites 1,822 pieces of research relating to the microbiome in 2011, which grew to 25,153 published in 2021. As more research has been conducted, closer and unexpected links have been found between the microbiome of the gut, as one example, and other areas of the body, such as brain health and the immune system.
That’s because the mutations that led to the variant’s emergence aren’t found in the regions of the virus that stimulates one type of cellular immuneresponse, says an international research team from Johns Hopkins Medicine, in collaboration with the National Institute of Allergy and Infectious Diseases (NIAID) and ImmunoScape, a U.S.-Singapore
Clinical Data Supporting Approval Demonstrated Non-Inferior ImmuneResponses for the Serotypes Shared with PCV13 (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F and 23F). VAXNEUVANCE Elicited Superior ImmuneResponses for Serotypes 3, 22F and 33F Compared to PCV13, Which Are Major Causes of Disease.
According to the American Academy of Dermatology , scientists believe that when a hair follicle becomes clogged with keratin, bacteria breed within it. When a hair follicle has more keratin and bacteria than it can hold, it bursts, causing the cyst-like breakout associated with HS. Clinical Research on Hidradenitis Suppurativa.
Some research shows that, when consumed, probiotics can help maintain a balanced gut microbiome, which supports gastrointestinal health and function. They can also help your body maintain a healthy community of microorganisms, produce substances that have desirable effects and influence your body’s immuneresponse. percent.
For their remarkable scientific contributions, doctoral student Julia Klaus, Zurich University VetSuisse Faculty, and Dr Yasmin Parr from the MRC-University of Glasgow, Centre for Virus Research, have received the 2021 ABCD Young Scientist Award. To foster young talent development in the feline health research community. References.
“I think that the pandemic has drawn much attention to some of the threats that have been posed by emerging infections,” says Brian Murphy, MD, MPH, FIDSA, Vice President of the Medical Department for global contract research organization (CRO) Medpace. And again, reminded us all of the importance of investing in public health.”.

But painstaking work by Australian researchers has revealed that people infected with the SARS-CoV-2 virus have immune memory to protect against reinfection for at least eight months. “Because of the biology of the persistence of these memory cells, it anticipates that we will have rather durable immunity,” said Dr. .
It may be caused by the immune system being triggered by a virus or bacteria that results in an atypical immuneresponse, or genetics play a role in disease development as it is more common in people whose immediate family members have Crohn’s disease.
And in healthcare and health research, trends towards increased digitization continued, including remote monitoring in clinical trials, use of wearable technologies and AI-based approaches to data collection, management and analysis. The results are promising and Moderna is set to go ahead with its planned Phase II trial for the vaccine.
