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.

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.

New test will help better manage patients with severe combined immunodeficiency

A new test developed at CHU Sainte-Justine in Montreal will enable better management of patients with severe combined immunodeficiency.

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.

New strategy may facilitate development of multi-epitope peptide vaccine against SARS-CoV-2

By combining T and B lymphocyte analysis with manufacturability heuristic, researchers from the US and Germany proposed a set of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine peptides to use in subsequent animal studies and clinical trials. Their paper is currently available on the bioRxiv preprint server.

How COVID-19 affects the nervous system

A new paper published in the journal JAMA Neurology in May 2020 discusses the presentation and complications of COVID-19 with respect to the nervous system.

Deep vein clots in critical COVID-19 illness

A new research paper published in the journal JAMA Network Open in May 2020 reports a high incidence of deep vein clots in patients with severe COVID-19 at a single French medical center. This could indicate the need for systematic anticoagulant therapy in these patients as a preventive measure.

IgG antibodies reduce viral load of SARS-CoV-2

A study conducted by researchers at the University of Washington has highlighted the importance of serological testing for infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Children with COVID-19 presenting with sudden severe lung disease

Even as the COVID-19 pandemic continues to seek out new victims, puzzling new presentations are further confusing the situation. A new study published online in The Lancet Rheumatology in May 2020 reports a case of severe COVID-19 in a child who rapidly developed acute respiratory distress symptoms without prior respiratory symptoms. This case should alert clinicians to consider this diagnosis in children as well.

Capillary leakage important in COVID-19 respiratory distress

Now, a new study published on the preprint server medRxiv reports the pivotal role played by protein leakage through lung capillaries and promotes the use of serum albumin as a biomarker of disease progression and severity.
