Human endogenous retrovirus type W envelope protein found to be a biomarker of COVID-19 severity

A new study revealed that the expression of HERV-W envelope protein (ENV) in lymphoid cells from COVID-19 patients correlated with disease outcome making them biomarkers of lymphocyte exhaustion.

Study finds Omicron infection effectively induces immunity against itself and enhances protection against other variants in vaccinated individuals

Researchers investigated the effectiveness of the SARS-CoV-2 Omicron-variant induced immunity, whether it is cross-protective against other variants, and if earlier infection with the SARS-CoV-2 Delta variant offers protection against Omicron.

Treatment with immune-boosting protein and radiation improves survival in mice with glioblastoma

Glioblastoma, an aggressive cancer in the brain or spinal cord, has proven stubbornly resistant to newer immunotherapies. And radiation and chemotherapy, the standard treatment for glioblastoma, result in fewer than 10% of patients surviving longer than five years after diagnosis.

Omicron infection induces cross-reactive immune responses

New research revealed that vaccine-breakthrough infections might elicit cross-reactive bNAbs against all variants of concern.

Reviewing myocarditis and pericarditis in immunosuppressed individuals following COVID-19 mRNA vaccination

A new study did not conclusively correlate the incidence of myocarditis or pericarditis with mRNA vaccination against SARS-CoV-2.

Thrombosis may increase mortality risk in hospitalized COVID-19 patients

A team of US-based scientists has recently explored various risk factors associated with the poor prognosis of coronavirus disease 2019 (COVID-19). They have identified thrombosis-related risk factors as a major predictor of in-hospital COVID-19 related mortality. The study is currently available on the medRxiv* preprint server while awaiting peer review.

Assay for the identification of SARS-CoV-2 Spike reactive T and B cells

An interesting new paper presents a new assay for B and T lymphocytes in individuals infected with SARS-CoV-2.

Immune responses against SARS-CoV-2 Delta variant after BNT162b2 vaccination in people living with HIV

Researchers from Sorbonne Universite have been investigating the effect of the BNT162b2 mRNA vaccine on HIV-positive individuals.

Scientists develop and characterize variant-specific vaccines against SARS-CoV-2

In a recent study conducted at Yale University, USA, scientists have investigated the immunogenicity of mRNA-based coronavirus disease 2019 (COVID-19) vaccine candidates encoding the spike proteins of different severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants. The findings reveal that the vaccines induce robust immune responses against SARS-CoV-2 variants. The study is currently available on the bioRxiv* preprint server.

New marker could lead to better diagnoses of Covid-19

Biomedical scientists at LMU have found a new marker in the blood of Covid-19 patients. It furnishes insights into the course and development of the disease and could lead to better diagnoses.

New approach to COVID-19 immune profiling using blood-based machine learning

A new study discusses the application of a novel deconvolution model AImmune to predict moderate and severe cases of COVID-19.

Exposure to Chikungunya may offer partial cross-protection against Mayaro virus

A study conducted at the University of São Paulo (USP) in Brazil suggests people previously infected by Chikungunya virus may develop partial immunity to Mayaro virus.

NEI researchers identify unique population of B cells that tamps down the immune system

Researchers at the National Eye Institute (NEI) have identified, isolated, and characterized a unique population of B cells that tamps down the immune system, reducing chronic inflammation.

Novel anti-inflammatory drug target identified by CRISPR

In this interview, News-Medical speaks to Dr. Jeffrey Rathmell about his recent research into how metabolic pathways impact immune function.

Study shows vaccinated multiple myeloma patients at greater risk of breakthrough SARS-CoV-2 infections

Researchers recently published a study assessing the risks of patients with MM to breakthrough infections after completing their vaccination schedule compared to those without any form of cancer.

Study compares immune responses of patients with and without kidney failure after COVID-19 vaccination

Death rates from COVID-19 are especially high in individuals with kidney failure who are on dialysis, making SARS-CoV-2 vaccination in this population a high priority.

Vaccine-induced immune responses for SARS-CoV-2 in patients receiving anti-CD20 B-cell depleting therapies

A new study published on the medRxiv* preprint server analyzed the trajectories of anti-SARS-CoV-2 antibodies in patients from the RituxiVac study were compared to healthy volunteers. In addition, they investigated the immunogenicity of a third vaccine dose in previously non-responding patients.

23 Nov 2021

Severe COVID-19 patients have significantly higher NK and T cell frequency

A new study published in the open-access journal Cells aimed to clarify the role of NK and T cell subsets in SARS-CoV-2 infection in hospitalized COVID-19 patients to unravel their potential association with disease severity.

Study: Covid-19 vaccine-elicited immune cells persist six months after vaccination

A recent study by Johns Hopkins Medicine researchers provides evidence that CD4+ T lymphocytes — immune system cells also known as helper T cells — produced by people who received either of the two available messenger RNA (mRNA) vaccines for COVID-19 persist six months after vaccination at only slightly reduced levels from two weeks after vaccination and are at significantly higher levels than for those who are unvaccinated.
