Deep profiling of SARS-CoV-2 immune response amongst the mildly symptomatic

In a research paper recently uploaded to the medRxiv* preprint server by Capelle et al. (September 2nd, 2021), the immune response of mild and hospitalized COVID-19 patients is compared, finding that early T-cell response is a vital indicator of SARS-CoV-2 disease severity.

Metabolic and immune markers as tools for risk stratification and monitoring in COVID-19

In a new study posted to the medRxiv* server scientists from Weil Cornell University and Stony Brook University in New York attempted to identify the metabolic and immune markers associated with severe COVID-19 disease using high-throughput targeted nuclear magnetic resonance (NMR) spectroscopy and high-dimensional flow cytometry. This will facilitate risk stratification, monitoring, and therapeutic interventions in COVID-19 patients.

Severe COVID-19 is associated with expansion of immature myeloid cells and inflammation

A team of scientists in Ireland recently identified certain immune markers that can predict the progression of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection to severe coronavirus disease 2019 (COVID-19). Early detection of these predictive markers can facilitate therapeutic decision-making prior to peak severity.

Development of SARS-CoV-2 antibody escape variants in an immunocompromised individual

A new study published in mBio discusses the microevolution of SARS-CoV-2.

Researchers study the role of low-density granulocytes in COVID-19

Information on granulocytes helps to understand mechanisms associated with covid-19 and other infectious diseases. Such information also promotes the development of better diagnostic methods and therapies.

Cytokine APRIL plays a protective role against formation of atherosclerotic plaques

Heart attacks and strokes are the main causes of death and loss of productive years globally. These clinical complications are caused by atherosclerosis, which is a chronic disease that leads to the accumulation of LDL cholesterol and immune cells in the inner layer of arteries and thereby resulting in the build-up of atherosclerotic plaques.

MSK researchers identify potential biomarker of response to checkpoint immunotherapy

In recent years, immune-based treatments for cancer have buoyed the hopes of doctors and patients alike. Drugs called immune checkpoint inhibitors have provided lifesaving benefits to a growing list of people with several types of cancer, including melanoma, lung cancer, bladder cancer, and many more.

Naive B cells could be useful for predicting vaccination response in immunocompromised

A recent study conducted at the Medical University of Graz, Austria, has revealed that the number of naïve B cells in the blood could independently predict the magnitude of immune response induced by coronavirus disease 2019 (COVID-19) vaccines in immunocompromised patients. The study is currently available on the medRxiv* preprint server.

COVID-19 vaccine likely protects people living with HIV, study shows

A Johns Hopkins Medicine research team has shown that people living with the human immunodeficiency virus (HIV) are likely to be protected against SARS-CoV-2, the virus that causes COVID-19, if they are fully vaccinated.

Long COVID may be due to persistent immune disturbances

A new study discusses abnormalities in the immune response following COVID-19 in samples collected from patients who have recovered from COVID-19.

Study shows efficacy of Pfizer-BioNTech and Moderna vaccines against SARS-CoV-2 delta variant

Researchers in Singapore have conducted a study showing that the messenger RNA- (mRNA) based coronavirus disease 2019 (COVID-19) vaccines developed by Pfizer-BioNTech and Moderna are highly effective at protecting against symptomatic and severe disease following infection with the rapidly spreading B.1.617.2 (delta) variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Scientists identify an antiviral metabolite as a potential serum biomarker for SARS-CoV-2 infection

Scientists from the UK have recently identified an antiviral metabolite 3'-Deoxy-3',4'-didehydro-cytidine as a potential serum biomarker to diagnose active severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The study is currently available on the medRxiv* preprint server while awaiting peer review.

Researchers use mass spectrometry to study immunogenic SARS-CoV-2 epitopes

A new study has been published on the bioRxiv* preprint server, which has used MS to identify T cell epitopes of SARS-CoV-2 conserved protein, i.e., the membrane glycol protein (MGP) and the non-structure protein-13 (NSP13).

Researchers identify novel disorder resulting from a mutation in AIOLOS protein

Primary immunodeficiencies, such as severe combined immunodeficiency disease (SCID), occur when the immune system does not work properly, leading to increased susceptibility to various infections, autoimmunity, and cancers.

Researchers study the role of subnuclear NSrp70 in T cell-mediated adaptive immunity

T cells are components of the body’s immune system. The ability of T cells to recognize diverse pathogens and mount a defense against them stems from the way proteins are spliced during their development and maturation.

15 Jul 2021

SARS-CoV-2 mRNA vaccine efficacy reduced in patients with CD20-B-cell depleting treatment history

Researchers from Switzerland recently investigated humoral and cell-mediated immune responses to mRNA-based vaccines in patients undergoing treatment with CD20-B-cell depleting agents for autoimmune diseases, transplantation, or malignancy.

What are predictive biomarkers of COVID-19 disease severity in pregnant women?

In a paper recently published in the Nature journal Scientific Reports, a retrospective cohort study on inflammatory biomarkers in pregnant women with COVID-19 reveals key differences that could better allow an accurate COVID-19 prognosis to be attained in pregnant women.

Researchers study COVID-19 immune dysfunction in relation to phosphatidylserine

Often patients suffering from COVID-19 (coronavirus disease) show striking immune dysregulation - causing increased morbidity and mortality. Mechanisms for adaptive immune disturbance, lymphopenia, and thromboinflammation in COVID-19 are still poorly understood.
