Antibody testing in L.A. county reveals the magnitude of coronavirus spread

After weeks of physical and social distancing measures in place, many in the U.S. are worrying about how soon they can return to normal life. However, to lift restrictions, it is critical to ascertain accurate numbers of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) carriers. Doing so will decrease the chance or even avoid the second wave of infections.

Researchers uncover how cancer cells don their invisibility cloaks

Immunotherapy drugs that target a protein called programmed death ligand 1 (PD-L1) on the surface of cancer cells have quickly become a mainstay to treat many forms of cancer, often with dramatic results. But exactly how cancer cells turn on this protein was not completely understood.

PiCoVacc vaccine candidate for COVID-19 effective in animal trials

In a new study available on the bioRxiv preprint server, a group of researchers from China report on the pilot-scale production of a purified inactivated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus vaccine candidate (PiCoVacc), shown to induce virus-specific neutralizing antibodies in rats, mice, and non-human primates.

The influence of crowding on COVID-19 transmission dynamics

Researchers in the United States have analyzed the effects that geographic factors have on the spread of COVID-19 disease. They found that the epidemic intensity is significantly influenced by crowding, with epidemics in densely-populated cities lasting longer and having a more significant overall incidence.

Researchers develop new 3D multicomponent dissolvable vaccine platform

In parallel to their current work on a potential coronavirus vaccine, researchers at the University of Pittsburgh School of Medicine have developed a new vaccine delivery system for vaccines using live or attenuated viral vectors: a finger-tip sized patch that contains 400 tiny needles, each just half of one millimeter.

Immunity to coronavirus infection may help stem the pandemic

The raging coronavirus pandemic is causing immense fear and uncertainty across the world. One of the most distressing aspects of COVID-19 disease is the seemingly large number of unknowns. These include the burning question of immunity. Does a person who was sick with the COVID-19 and then recovered or was infected without symptoms, have immunity against re-infection?

Difference between flu and novel coronavirus disease

Both influenza and COVID-19 disease are caused by infectious respiratory agents and cause symptoms that can look quite similar. Coronaviruses cause both. So, what’s the difference?

Antibodies against Imood could be potential treatment for OCD

Mental health conditions such as obsessive compulsive disorder could be treated in a new way using drugs that target the immune system, research suggests.

Study shows why MDS cells have a competitive advantage that supports disease progression

A powerful clue has emerged in a long-running mystery about how the cells of myelodysplastic syndrome (MDS) manage to outcompete normal blood cells to cause a disease state that often leads to leukemia, according to a study published online April 20, 2020, in Nature Immunology.

COVID-19 and immunodeficiency

COVID-19 disease, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a highly infectious disease. As of today, over 170,000 people worldwide have succumbed to the infection. Reports have shown that some comorbidities and illnesses raise the risk of getting infected and also influence the severity of the disease. Having a compromised immune system can also drastically raise the risk of getting COVID-19.

Antibody detection for COVID-19 - promise and risks

Recently, several research groups emphasized how the pervasive screening for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies may prove pivotal in determining infection seroprevalence in a given population defining previous exposure, screening health care workers, but also identifying highly reactive individuals that may act as donors for the therapeutic use of their convalescent serum.

Penn Medicine launches convalescent plasma therapy trial for COVID-19 patients

Convalescent plasma therapy for COVID-19 patients -- an experimental approach of giving a transfusion of plasma collected from a donor who has recovered from COVID-19 to a patient with an active infection -- is the focus of a new two-part research initiative at Penn Medicine.

Study reveals new therapeutic options for multiple sclerosis

Multiple sclerosis is known as "the disease with a thousand faces" because symptoms and progression can vary dramatically from patient to patient.

Projecting the transmission dynamics of COVID-19 pandemic

As the COVID-19 pandemic continues, a major unanswered question is how SARS-CoV-2 will persist in the human population after its initial pandemic stage.

UC San Diego Health launches serological tests to detect past exposure to novel coronavirus

Clinical laboratory physicians and scientists at UC San Diego Health have launched a pair of serological tests that will look for novel coronavirus antibodies -- evidence in persons tested that they have previously been infected by SARS-CoV-2, the viral cause of COVID-19, even if they never experienced tell-tale symptoms.

McMaster researchers to study why some people are more susceptible to SARS-CoV-2

Two McMaster University professors have received research funding to boost their work to identify COVID-19 infection rates and to understand why some people are more susceptible to the virus.
