Study associates higher antibody titers with naïve B cells post-mRNA vaccination

Researchers compared peripheral blood mononuclear cells in people with high and low antibody titers after two doses of the Pfizer/BioNTech (BNT162b2) mRNA vaccine. They found a positive correlation between naïve B cells present before vaccination and high antibody titers.

Oxford-AstraZeneca COVID-19 vaccine induces robust T cell-based immunity

A recent study conducted by an international team of scientists has revealed that the Oxford-AstraZeneca coronavirus disease 2019 (COVID-19) vaccine, AZD1222, is capable of inducing strong spike-specific CD4+ T cell helper type 1 (Th1) and CD8+ T-cell responses in vaccinated individuals. A detailed description of AZD1222-induced cellular immunity is currently available on the medRxiv* preprint server.

Multisystem Inflammatory Syndrome in Children significantly affects more Black and Latino children

Multisystem Inflammatory Syndrome in Children (MIS-C) significantly affected more Black and Latino children than white children, with Black children at the highest risk, according to a new observational study of 124 pediatric patients treated at Children's National Hospital in Washington, D.C.

Research reveals how autonomic nervous system influences deep sleep in sleepwalkers

Somnambulism - otherwise known as sleepwalking - is a phenomenon which has fascinated the public and neurologists for decades, but a lot of what causes it remains a mystery.

Scientists predict driver mutations of future SARS-CoV-2 variants of concern

A team of scientists from the USA has recently predicted the driver mutations that may appear in future variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The prediction is based on currently available genetic surveillance data on amino acid mutations present in SARS-CoV-2 variants. A detailed description of the study is currently available on the medRxiv* preprint server.

Is COVID-19 more severe in pregnancy?

A new study, released as a preprint on the medRxiv* server, indicates that pregnant women are more likely to develop severe disease following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

Bivalent DNA SARS-CoV-2 vaccine induces strong humoral and cellular immunity in mice

A team of UK-based scientists has developed and validated a DNA vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that encodes both spike receptor-binding domain (RBD) and nucleocapsid of the virus as vaccine immunogens.

Machine-learning approach could accurately predict the evolution of breast cancer

From amoebas to zebras, all living things evolve. They change over time as pressures from the environment cause individuals with certain traits to become more common in a population while those with other traits become less common.

SARS-CoV-2 Delta variant likely to become dominant in the United States

Researchers have conducted a study showing that the B.1.1.7 lineage of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that emerged in the UK is now rapidly being displaced as the dominant strain in the United States by the variants of concern B.1.617.2 (Delta) and P.1 (Gamma) that emerged in India and Brazil, respectively.

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.

mRNA COVID-19 vaccines may increase patients' concerns about side effects

Vivid photos of the red "COVID arm" rash and reports of facial swelling in patients who have received dermatological fillers after Pfizer-BioNTech or Moderna vaccination for COVID-19 may increase patients' concerns about mRNA vaccine side effects and contribute to vaccine hesitancy.
