Study fills crucial knowledge gaps on myasthenia gravis

A study of 181 patients at 16 sites across the country who test negative for two antibodies long known to cause muscle-weakening myasthenia gravis, found that about 15% test positive for one of two newly discovered antibodies that also attack the point of communication between nerves and muscle.

Structural analysis of SARS-CoV-2 can help develop COVID-19 vaccines

At the start of a COVID-19 infection, the coronavirus SARS-CoV-2 docks onto human cells using the spike-like proteins on its surface.

Large SARS-CoV-2 outbreak on a fishing boat - neutralizing antibodies prevent infection

Now, a team of researchers at the University of Washington School of Medicine has found evidence that SARS-CoV-2 neutralizing antibodies can prevent infection in people, as they conducted a study before and after a COVID-19 outbreak on a fishing vessel.

The world is 'nowhere near herd immunity,' WHO says

Now, the World Health Organization (WHO) says that the world is nowhere near the amount of coronavirus immunity needed to induce herd immunity, where enough people would develop the antibodies to stop the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Acidic niche within lymph nodes plays integral role in regulating T cell activation

In the fight against cancer, the immune system is the first line of defense. The lymphatic system specifically is essential to protecting the body against foreign invaders.

Antibody and cellular immunity in severe vs. mild COVID-19

Now, a new study published in the journal Signal Transduction and Targeted Therapy in August 2020 shows that while humoral and T-cell immune responses are more robust in severe infection, the disease activates memory T cells as part of the adaptive immune system in COVID-19 patients irrespective of disease severity.

COVID immunity related to how bad you get it

Researchers at Stanford University in California have shown that severely ill patients hospitalized with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection develop significantly higher levels of antibodies against the virus than asymptomatic individuals and outpatients.

Cryo-EM experiments offer important clues to chicken pox infection

Despite decades of study, exactly how herpesviruses invade our cells remains something of a mystery. Now researchers studying one herpesvirus, the varicella zoster virus (VZV) that causes chicken pox, may have found an important clue: A key protein the virus uses to initiate infection does not operate as previously thought, researchers at Stanford University and the Department of Energy's SLAC National Accelerator Laboratory report August 18 in Nature Communications.

Study to explore risks and benefits of breastfeeding during COVID-19

To breastfeed or not to breastfeed? Science has long supported that "breast is best," but COVID-19 has brought with it new questions related to the benefits and/or potential risks of breastfeeding during this pandemic.

Study shows why young, female patients have low response rates to cancer immunotherapy

Cancer immunotherapy -- empowering a patient's own immune system to clear away tumors on its own -- holds great promise for some patients. But for other patients, immunotherapy just doesn't work.

Majority of recovered COVID-19 patients have low neutralizing antibody titers

Now, a new study by researchers at New York University and published on the preprint server bioRxiv* in August 2020 reports on the type and intensity of anti-SARS-CoV-2 antibodies in recovered COVID-19 patients and the implications of these findings.

Novel receptor protein may hold promise for treating COVID-19

A novel receptor protein that binds to the SARS-CoV-2 virus and prevents it from entering cells may hold promise for treating COVID-19 and other coronavirus-related diseases, according to research published online Aug. 4 in the journal SCIENCE.

Mild COVID-19 cases can trigger robust memory T cell responses

Mild cases of coronavirus disease 2019 (COVID-19) can trigger robust memory T cell responses, even in the absence of detectable virus-specific antibody responses, researchers report August 14 in the journal Cell.

Pre-COVID-19 coronavirus immunity does not protect against SARS-CoV-2

A recent study by researchers in France that's currently available on the medRxiv* preprint server claims that having previous immunity against common coronaviruses (alpha and beta) cannot protect against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
