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.

Circadian rhythm affects SARS-CoV-2 infection and host immune response

In an interesting bioRxiv preprint paper, French researchers show that the time day can affect infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as well as guide subsequent host immune response – implying that circadian rhythm may well be a novel target for managing viral progression.

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).

India's whole-virion inactivated SARS-CoV-2 vaccine shows promise

Researchers in India have conducted a preclinical study demonstrating the safety and efficacy of a new candidate vaccine for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent that causes coronavirus disease 2019 (COVID-19).

SARS-CoV-2-RNA viremia is a robust marker of critical illness in COVID-19

A new study by a large team of Spanish researchers and published on the preprint server medRxiv* in August 2020 reports that the presence of viral RNA in the blood is a useful marker of impending acute disease and can help triage COVID-19 disease patients who will require hospital care.

Research shows how brain’s immune defenses respond to strokes in babies

New research from the University of Virginia School of Medicine is shedding light on the development of the brain's immune defenses - and how those defenses respond to strokes that strike one in 4,000 babies in the first month of life.

Serum protein shows therapeutic value against severe COVID-19-like features in mouse model

A new study published on the preprint server bioRxiv* in August 2020 reports the disease-mitigating effects of a serum protein called serum amyloid P (SAP) in mice exposed to a peptide that mimics the clinical signs of severe COVID-19 in humans.

Researchers find link between dystrophic muscles and lymphatic system in mice with Duchenne disease

Researchers at the Universities of Maynooth and Bonn discover a new connection in muscular dystrophy Duchenne muscular dystrophy (DMD) is the most common muscle disease in children and is passed on by X-linked recessive inheritance.

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.

Reelin inhibition may be effective for treating multiple sclerosis

In an animal model of multiple sclerosis (MS), decreasing the amount of a protein made in the liver significantly protected against development of the disease's characteristic symptoms and promoted recovery in symptomatic animals, UTSW scientists report.

C-type lectin receptors play a role in SARS-CoV-2 infection

A new study published on the preprint server bioRxiv in August 2020 confirms and extends earlier findings showing that a type of sugar-based receptor on innate immune cells promotes the entry of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) into other cells that carry the viral receptor, angiotensin-converting enzyme 2 (ACE2).

A multi-omics single cell analysis on COVID-19

Now, a new study published on the preprint server medRxiv aims to analyze the immune response over time, using multi-omics in the study of a single cell.

Study shows how radiotherapy alters the behavior of immune cells in glioblastoma tumors

A Ludwig Cancer Research study has dissected how radiotherapy alters the behavior of immune cells known as macrophages found in glioblastoma (GBM) tumors and shown how these cells might be reprogrammed with an existing drug to suppress the invariable recurrence of the aggressive brain cancer.

Study reveals how overactive immune cells aggravate heart valve disease

A new study using organ-on-a-chip technology reveals how overactive immune cells aggravate heart valve disease and how this damaging hyperactivity could potentially be controlled.

Faulty immune response to SARS-CoV-2 one of the main causes of death

A new study published on the preprint server medRxiv in July 2020 describes the organ and tissue-specific spread of the virus causing the current COVID-19 pandemic, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

BMI should be assessed in management of COVID-19 patients

A new study published on the preprint server medRxiv* in June 2020 reports that obesity is a risk factor of composite poor outcome of COVID-19 disease. On the other hand, COVID-19 patients with 'composite poor outcome' have higher BMI. Therefore, BMI should be assessed in the management of COVID-19 patients, and special attention should be given to patients with obesity.

Potential new biomarker could improve COVID-19 diagnosis

Researchers at Montpellier University Hospital have discovered that an interferon-inducible receptor expressed on monocytes could be a useful biomarker for the rapid triaging of patients suspected to have severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Dysregulated inflammation in severe COVID-19

The continuing COVID-19 pandemic has so far caused 9.58 million cases and more than 488,000 deaths within just six months. The spectrum of disease is broad, from completely asymptomatic cases to critical illness ending in death. Now, a new paper by researchers from Yale University and published on the preprint server medRxiv* in June 2020 identifies an imbalance in immunological response that is linked to poor outcomes and early biomarkers that may help predict the course of the disease.

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.

Hydroxychloroquine suppresses 'trained immunity'

A new study published on the preprint server medRxiv in June 2020 shows that the drug hydroxychloroquine (HCQ) suppresses a form of immunity called ‘trained immunity,’ with repercussions for its potential use to treat COVID-19.
