ARDS may not be the primary lung iInjury in COVID-19

A new Italian study published on the preprint server medRxiv in August 2020 shows that this may not be an adequate explanation, since ARDS is a nonspecific diagnosis. Instead, they say, antemortem lung biopsy shows a “Covid pattern” of acute lung injury, which could guide the application of therapeutics.

SARS-CoV-2 spike protein recognized by innate immune receptors in a glycan-dependent way

The spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) depends on its ability to infect new host cells following its replication and release from infected cells. This pivots on its ability to bind to cell surface receptors like the ACE2 enzyme.

Researchers identify anticoagulation agent that suppresses SARS-CoV-2 replication in vitro

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can cause acute respiratory distress syndrome, hypercoagulability, hypertension, and multiorgan dysfunction.

Study uncovers dual role for molecule involved in autoimmune eye disease

The inflammatory molecule interleukin-17A (IL-17A) triggers immune cells that in turn reduce IL-17A's pro-inflammatory activity, according to a study by National Eye Institute researchers.

Prednisone, Hydroxychloroquine best among COVID-19 treatments, claims large Spanish study

The COVID-19 pandemic has taken the lives of several hundred thousand people across the world. In Spain, a intense outbreak took a toll of over 28,000 lives.

Mouse model of fatal COVID-19 developed for vaccine and drug testing

Now, a new study published on the preprint server bioRxiv in July 2020 presents an engineered transgenic mouse that reproduces the functional and clinical characteristics of severe human SARS-CoV-2 infection.

GlobalData: Hematology tests can be a prognostic marker to predict severity of COVID-19 patients

With the rapid increase in the number of COVID-19 cases across India, identifying the critically ill COVID-19 patients in the early stage of infection can help in assessing the risk stratification and clinical management.

How immune cells switch to attack mode

Unraveling a key motif: The T lymphocytes of the immune system work to destroy infected cells or cancer cells. To do so, they have to identify the threat: Molecules perceived as foreign - so-called antigens - bind to the T-cell receptor on the T cell surface.

COVID-19 – researchers sum up the “Tsunami” of information

The severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) infection leading to COVID-19 is a raging pandemic across the world at present. It has infected 13 million and killed 571,000 individuals around the world as of today. The infection was first reported in Wuhan, Hubei Province of China in late December 2019.

Clots, COVID-19 and survival

The novel coronavirus, now known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), that causes COVID-19 disease, was first reported in Wuhan, Hubei Province of China in late December 2019. Since then, it has infected a large population across the world with the current number of SARS-CoV-2 infections standing at over 13 million and COVID-19 disease having killed over 571,000 individuals.

Dysfunctional T cells present at high levels in severe COVID-19

Now, a new study by researchers at Saarland University, Germany, and published on the preprint server medRxiv in July 2020 shows that there are higher levels of anti-SARS-CoV-2 T cells, which show significant alterations in the phenotype and function.

No unique viral sequences found in pediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2

In contrast to previous hypotheses, researchers from the University College London and Great Ormond Street Hospital for Children NHS Foundation Trust found no evidence of unique viral sequences from patients with pediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS). Their study is published on the medRxiv* preprint server.

Study: Cellular therapy can improve critical cases of COVID-19

A cellular therapy tested on 13 intubated patients with mechanical ventilation has shown to be efficient for the clinical improvement of critical cases of COVID-19.

Oral hygiene and severity of COVID-19 – the connection

Their study titled, “Could there be a link between oral hygiene and the severity of SARS-CoV-2 infections?” was published in the latest issue of the journal British Dental Journal.

Certain genes that predispose to cancer also affect the immune system, study shows

The study shows that the involvement of certain genes that predispose to cancer also affects the immune system, which could facilitate tumor growth.

Immune response variations across the COVID-19 spectrum

A new study published on the preprint server medRxiv in June 2020 describes differences in the adaptive and innate immune response in mild, moderate, and severe COVID-19. This may mean that permanent immune responses occur only in patients who recover from severe COVID-19.

Researchers investigate nelarabine drug for treating leukemia

Acute lymphoblastic leukemia (ALL) is the most common kind of cancer in children. T-ALL, a subtype that resembles T-lymphocytes, can be treated successfully with the drug nelarabine.

Balanced B and T cell response required to control SARS-CoV-2

A new study by researchers in the Netherlands and published on the preprint server bioRxiv in June 2020 describes the differences in T and B cell responses seen in patients with severe COVID-19.

Monocytes could be critical in dysregulated immunity in COVID-19

A new study by Spanish researchers as part of the GEN-COVID Project, and published on the preprint server medRxiv* in June 2020, suggests that monocytes are primarily involved in triggering the hyperinflammatory immune response that may underlie severe COVID-19 infection.
