Prior spike protein exposures shape protection against SARS-CoV-2 Omicron variant

Researchers found that immune-boosting by SARS-CoV-2 Omicron variant is contingent on prior COVID-19 history.

Researchers evaluate artemisinin for COVID-19 management

Researchers assessed the effectiveness of artemisinin-based antimalarials in the management of COVID-19.

Cryo-electron microscopy structure of SARS-CoV-2 membrane protein

In a recent study posted to the bioRxiv* pre-print server, researchers illustrated the cryo-electron microscopic (cryo-EM) structure of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) membrane (M) protein in lipid nanodiscs to 3.5 angstroms (Å) resolution.

Research suggests profound SARS-CoV-2 mutations are rare even among immunosuppressed

A recent article posted to the medRxiv* preprint server assessed whether host traits like immunosuppression aids severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mutational drift.

Study confirms heightened protection from Omicron-associated hospitalizations by COVID boosters

In a recent article posted to the medRxiv* preprint server, scientists assessed the efficacy of the primary and boosted regimens of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccinations in preventing SARS-CoV-2 Omicron-linked hospitalizations in the United States (US).

Obesity causes COVID vaccines to lose their efficacy more rapidly

In a recent study posted to the medRxiv* pre-print server, researchers examined a clinical cohort of severely obese people vaccinated with coronavirus disease 2019 (COVID-19) vaccines to determine the relationship between an individual's body mass index (BMI) and COVID-19-related hospitalization and mortality.

Vaccination provides good but temporary protection against SARS-CoV-2 omicron infection, study shows

A recent Pfizer or Moderna mRNA-vaccine booster provided good but temporary protection against infection by the SARS-CoV-2 omicron variant, according to a study from researchers at Weill Cornell Medicine—Qatar.

Two broadly neutralizing antibodies show promise to provide long-acting immunity against SARS-CoV-2

Two broadly neutralizing antibodies show great promise to provide long-acting immunity against COVID-19 in immunocompromised populations according to a paper published June 15 in the Journal of Experimental Medicine (JEM).

Cellular "barcoding" in mice unravels the origins of blood

The origins of our blood may not be quite what we thought. Using cellular "barcoding" in mice, a groundbreaking study finds that blood cells originate not from one type of mother cell, but two, with potential implications for blood cancers, bone marrow transplant, and immunology. Fernando Camargo, PhD, of the Stem Cell Program at Boston Children's Hospital led the study, published in Nature on June 15.

New test can tell if you are immune to SARS-CoV-2

In a recent study published in the journal Nature Biotechnology, an international team of researchers developed and evaluated quantitative polymerase chain reaction (qPCR)-based assays to quantify severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-specific functional T cell immunity.

SARS-CoV-2 Omicron breakthrough infection less immunogenic than Delta

Scientists investigate the sequence and dynamics of recalled immune memory in convalescent individuals who have been vaccinated against COVID-19.

The severity of COVID-19 compared to seasonal influenza

In a recent study under review at the Archives of Virology journal and currently posted to the Research Square* preprint server, investigators in Israel assessed the disparities and similarities between seasonal influenza and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections.

SARS-CoV-2 recombinant isolated from chronic COVID-19 patient

A new research paper in the journal Viruses reports the isolation of a recombinant strain in a patient infected with the virus for over a year.

Stress accelerates aging of the immune system

Stress - in the form of traumatic events, job strain, everyday stressors and discrimination - accelerates aging of the immune system, potentially increasing a person's risk of cancer, cardiovascular disease and illness from infections such as COVID-19, according to a new USC study.

Treatment with immunity-boosting protein enhances the function of CAR-T cells in fighting blood cancers

Advances in cellular immunotherapy that spur genetically modified T cells to attack cancer cells have revolutionized the treatment of certain blood cancers.

Commercial T cell test offers insight into immune responses after COVID-19 infection and vaccination

T cell testing using a commercial T cell test, QuantiFERON SARS-CoV-2 RUO, offers insight into the immune response to infection and vaccination of patients with COVID-19 and suggests that age and time from infection are significant factors related to the magnitude of cell-mediated immune (CMI) responses to COVID-19.
