A study contradicting the phenotypical relationship between plasmablasts and developing neutrophils

A team of scientists from Australia challenges the findings of a recent study by Wilk et al. demonstrating that plasmablasts transdifferentiate into developing neutrophils in severe coronavirus disease 2019 (COVID-19). The Australian study is currently available on the bioRxiv preprint server.

Hamsters and ferrets clear low dose SARS-CoV-2 infection in 14 days

A recent study by French researchers has demonstrated that experimental exposure to severe acute respiratory coronavirus 2 (SARS-CoV-2) is capable of inducing mild infection in hamsters and ferrets within 7 – 10 days of exposure. However, the infection completely resolves within 14 days. The study is currently available on the bioRxiv preprint server.

Anti-N-protein IgG may predict severity of COVID-19

A recent study by researchers at the University of Miami, Miami VA Healthcare System and Express Gene and published on the preprint server medRxiv in September 2020 reports on the prognostic significance of the anti-N Immunoglobulin G (IgG) antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Risk factors for mortality among hospitalized patients with COVID-19

A new study by scientists at biotechnology company Genentech, Inc., and published on the preprint server medRxiv in September 2020 attempts to identify the factors which may shape the risk for death in COVID-19 disease.

AI used to define the cytokine storm implicated in fatal COVID-19

A new study published on the preprint server bioRxiv* in September 2020 reports the use of artificial intelligence (AI) to identify an invariant or universal host immune response found in all viral pandemics so far. The association of this response with severe COVID-19 phenotypes indicates a new understanding of the human immune response in viral pandemics.

Research says in SARS-CoV-2 canine infection, transmission unlikely

A new study published on the preprint server bioRxiv* in September 2020 shows that pet dogs have been falling sick and dying of a mysterious respiratory infection, often showing the presence of anti- severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies, even though in many cases they do not test positive for COVID-19.

Stroke patients with COVID-19 have increased systemic inflammation, higher mortality risk

Stroke patients who also have COVID-19 showed increased systemic inflammation, a more serious stroke severity and a much higher rate of death, compared to stroke patients who did not have COVID-19, according to University of Alabama at Birmingham research led by Chen Lin, M.D., an assistant professor in the UAB Department of Neurology.

Animal data supports efficacy of baricitinib vs SARS-COV-2

The high burden of disease caused by the COVID-19 pandemic has led to much research on effective ways to mitigate the health, social, and economic impact of the spread of the infection. A recent study published on the preprint server bioRxiv* in September 2020 reports on the characteristics of the drug baricitinib when used as monotherapy to treat severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Biomarker predicts disease severity in COVID-19 patients

Airway cell analyses showing an activated immune axis could pinpoint the COVID-19 patients who will most benefit from targeted therapies.

LOX-1-immature neutrophils may help identify COVID-19 patients at risk of thrombosis complication

To predict severe outcome in COVID-19 patients, innate immune cellular signals are analyzed, identifying two novel neutrophil subsets: LOX-1- and CD123-expressing CD10-CD64+. Thromboembolic events correlated with high LOX-1 immature neutrophils – a potential prognostic signature.

New mechanism could explain how immune cancer cells migrate in various fluid-filled niches

Human white blood cells, known as leukocytes, swim using a newly described mechanism called molecular paddling, researchers report in the September 15th issue of Biophysical Journal.

Study highlights role of specific protein in the mass production of antibodies

Antibodies play a fundamental role in medicine, and antibody-mediated immune response is the ultimate target in the quest for a vaccine to defeat the current pandemic.

Researcher describes a new approach to study the process of wound healing

Our bodies frequently heal wounds, like a cut or a scrape, on their own. However patients with diabetes, vascular disease, and skin disorders, sometimes have difficulty healing.

Study reveals damaging role of immune system in severe brain infection

A new study has detailed the damaging role played by the immune system in a severe brain condition most commonly caused by the cold sore virus.

Researchers detect significant amounts of DNA traps in lungs of deceased Covid-19 patients

A multidisciplinary team of researchers from the University of Liège (Belgium) has detected significant amounts of DNA traps in distinct compartments of the lungs of patients who died from Covid-19.

Keto diet could be beneficial for elderly COVID-19 patients

A recent study by researchers at Yale School of Medicine, New York University Langone Health and Washington University School of Medicine, claims that the ketogenic diet (high fat, low carbohydrate diet) is capable of mitigating clinical outcomes of coronavirus disease 2019 (COVID-19) in elderly people by improving immune-metabolic functions and reducing inflammation. The study is currently available on the bioRxiv* preprint server.

Sticky DNA webs may cause tissue damage associated with severe COVID-19 infections

Sticky webs of DNA released from immune cells known as neutrophils may cause much of the tissue damage associated with severe COVID-19 infections, according to two new studies published September 14 in the Journal of Experimental Medicine.

Shedding light on altered blood cell traits involved in severe COVID-19

Researchers at the University of Georgia in the United States have shed light on the pathological mechanisms underlying the association between the genetic locus 3p21.31 and severe coronavirus disease 2019 (COVID-19).

Sex-differential COVID-19 responses are mediated by kynurenic acid

Now, a new study by a research team from Yale University, USA, Edith Cowan University, Australia, and the University of Strathclyde, Scotland, and published on the preprint server medRxiv in September 2020 shows that kynurenic acid is the underlying factor which is responsible for these differences.

Limited gut inflammation in COVID-19

A new study by researchers at the Icahn School of Medicine at Mount Sinai and published on the preprint server medRxiv in September 2020 shows that gut infection with this virus produces primarily mucosal immunity but also a limited inflammatory response.
