Vaccine candidate targeting SARS-CoV-2 nucleocapsid protein elicits protective immune response in animal model

New preclinical results from a study led by David Masopust of the University of Minnesota in Minneapolis, USA, show that a Had5-based vaccine targeting the nucleocapsid protein can also elicit a protective immune response.

Comprehensive "cell atlas" shows how COVID-19 can lead to organ failure and death

Scientists from several hospitals and research centers have shown what happens in individual cells of patients who died of COVID-19. In a study published in Nature, the researchers describe how infected cells from multiple organs exhibited a range of molecular and genomic changes.

New cocaine and oxycodone biobanks provide investigatory therapeutic targets for addiction

A major hurdle to developing new and effective treatments for drug addiction is better understanding how exactly it manifests itself before, during and after chronic use.

New method helps map the specialized diversity and spatial location of cells within a tissue or tumor

Not all cancer cells within a tumor are created equal; nor do all immune cells (or all liver or brain cells) in your body have the same job. Much of their function depends on their location.

Cocoa consumption improves health of obese mice with liver disease

Supplementation of cocoa powder in the diet of high-fat-fed mice with liver disease markedly reduced the severity of their condition, according to a new study by Penn State researchers, who suggest the results have implications for people.

ACE2 homology in laboratory and wild animals

A new preprint research paper posted to the bioRxiv server describes the conservation of an important receptor gene for the virus among several animal species that live in close contact or proximity to humans.

Allogeneic adipose-derived stem cells can mitigate TBI-induced acute radiation syndrome

Nuclear power offers an efficient, reliable way to provide energy to large populations - as long as all goes well. Accidents involving nuclear reactors such as those that took place in 1986 at Chernobyl and at Fukushima Daiichi after the March 2011 tsunami raise major concerns about what happens if the worst occurs and large numbers of people are simultaneously exposed to high levels of radiation.

New high-performance, safe MRI contrast agent for 3D vascular mapping

Heart attack and stroke are the first and second leading causes of death in developed countries, respectively. As the disease often results in sudden death with few special prognostic symptoms, early diagnosis is very important.

Somatic gene mutations in brain cells could contribute to schizophrenia pathology

Schizophrenia is a neurodevelopmental disorder that disrupts brain activity producing hallucinations, delusions, and other cognitive disturbances. Researchers have long searched for genetic influences in the disease, but genetic mutations have been identified in only a small fraction--fewer than a quarter--of sequenced patients.

Researchers develop ultrapotent miniproteins that target SARS-CoV-2 receptor-binding domain

Researchers have investigated the effectiveness of a bioengineered miniprotein in protecting against SARS-CoV-2 infection in vivo. The researchers evaluated the miniprotein, LCB1, against SARS-CoV-2-mediated lung disease in human ACE2-expressing transgenic mice.

SARS-CoV-2 viremia predicts severe COVID-19 disease outcomes

The SARS-CoV-2 plasma viremia has been linked to severe disease and death in COVID-19 cases in small-scale cohort studies. The current study, published on the pre-print server medRxiv, aimed to study the mechanisms behind this relationship.

Could an intranasal adjuvant to vaccines boost immunity against SARS-CoV-2 variants?

A research team from the University of Michigan Medical School, USA, developed a supplementary intranasal treatment to improve COVID-19 vaccine response and its effects on long-lasting immunity from other variants, such as the B.1.351 variant first found in South Africa.

What are the changes in the physical phenotype of blood cells in COVID-19?

While primarily a respiratory illness, there are distinctive alterations in the type and number of blood cells in COVID-19. A new study by a team of researchers in Germany describes the nature of these changes.

Cell-selective nanotherapy can help treat atherosclerotic plaques

Percutaneous coronary intervention (PCI), commonly known as angioplasty with a stent, opens clogged arteries and saves lives. Despite its benefit in treating atherosclerosis that causes coronary artery disease, this common minimally-invasive procedure still poses severe complications for some patients.

Cellular survival after radiation exposure depends on the specific protein behavior

Exposure to radiation can wreak indiscriminate havoc on cells, tissues, and organs. Curiously, however, some tissues are more vulnerable to radiation damage than others.

Gut fungi teach the immune system how to respond to their dangerous relatives

Common fungi, often present in the gut, teach the immune system how to respond to their more dangerous relatives, according to new research from scientists at Weill Cornell Medicine. Breakdowns in this process can leave people susceptible to deadly fungal infections.

Could intranasal SARS-CoV-2 vaccines be a practical alternative to intramuscular shots?

The unchecked advance of COVID-19 has made it a top public health priority to produce a vaccine capable of inducing a safe and powerful protective response against its causative pathogen: SARS-CoV-2. An encouraging new study shows the immunogenicity, safety, and protective efficacy, of a Newcastle disease virus (NDV)-based intranasal vector vaccine in animal studies.

Poor gut health may adversely affect COVID-19 prognosis

People infected with COVID-19 experience a wide range of symptoms and severities, the most commonly reported including high fevers and respiratory problems.

Study investigates effect of anti-CD45 RIT lymphodepletion on immune cell types

Oncotarget recently published "Targeted lymphodepletion with a CD45-directed antibody radioconjugate as a novel conditioning regimen prior to adoptive cell therapy" which reported that Chimeric antigen receptor T cell therapies, and adoptive cell therapy in general, represent one of the most promising anti-cancer strategies.
