Is Hong Kong’s fourth wave of COVID-19 due to the Q57H SARS-CoV-2 variant?

A recent article in the Centers for Disease Control and Prevention (CDC)’s Emerging Infectious Diseases reveals that the last of these was probably due to the introduction of a new variant from Nepal. This novel variant had been circulating in the community for about a month before the last outbreak was reported.

Peptide nucleocapsid vaccine candidate elicits protective T cell immunity against SARS-CoV-2 in vivo

A new study describes a synthetic peptide used as a platform to generate protective adaptive cellular immunity to the virus in rhesus macaques, which are the gold standard for preclinical testing in humans.

Novel platform has potential to detect many disease-related biomarkers in just one test

Most conventional molecular diagnostics usually detect only a single disease-related biomarker. Great examples are the PCR tests currently used to diagnose COVID-19 by detecting a specific sequence from SARS-CoV-2.

SARS-CoV-2 antibody response robust in nursing home residents after Pfizer-BioNTech vaccine

However, with the waning of the immune response, it is not clear if these older people respond to the vaccine as well as younger individuals do. A recent study explored this question and found that though the antibody levels were somewhat lower in this group, they were still robust. This is a promising observation.

Striking difference identified between mRNA vaccination vs. SARS-CoV-2 infection immune responses

A team of scientists from the United States has recently compared the immune response elicited by natural severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and coronavirus disease 2019 (COVID-19) vaccination. Their findings reveal that, unlike vaccination, natural SARS-CoV-2 infection is associated with a robust interferon response together with an induction of cytotoxic gene expression in peripheral blood lymphocytes. The study is currently available on the medRxiv* preprint server.

Interfering RNA nanoparticles could be a potential COVID-19 therapy

Study shows lipid nanoparticle-based siRNA is potent in suppressing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the causative agent of coronavirus disease 2019 (COVID-19) – in cells as well as in mice models.

SARS-CoV-2 pandemic underscores importance of understanding evolution of RNA genomes

The current COVID-19 (coronavirus disease 2019) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), underscores the importance of understanding the evolution of ribonucleic acid (RNA) genomes.

Chronic SARS-CoV-2 infections favor viral adaptation, says study

A new study offers a look at how to keep these hopes alive in the current context of highly infectious variants, which often display immune escape mutations.

Limited SARS-CoV-2 spread in childcare centers, finds study

A new study adds to the sum of evidence that children do not play a key role in the transmission of the SARS-CoV-2, the pathogen behind the current pandemic of COVID-19.

Study sheds light on how tau aggregates promote Alzheimer’s disease

Look deep inside the brain of someone with Alzheimer's disease, most forms of dementia or the concussion-related syndrome known as chronic traumatic encephalopathy (CTE) and you'll find a common suspected culprit: stringy, hairball-like tangles of a protein called tau.

Rapid mRNA vaccination effectively controls SARS-CoV-2 transmission in long-term care facilities

Vaccine rollouts all over the world are aimed at cutting short the coronavirus disease 2019 (COVID-19) pandemic by inducing antibody-mediated immunity to the virus. A new study, recently released on the medRxiv* preprint server, addresses the successful reduction in viral spread and case incidence among residents of long-term care facilities (LTCF).

COVID-19 vaccination of lactating mothers elicits specific IgA antibodies in breast milk

A new study, released on the medRxiv* preprint server, examines the presence of SARS-CoV-2-specific IgA in human milk and its association with the protection of breastfed infants against the disease.

Ovarian follicular function unaffected by SARS-CoV-2 infection or Pfizer vaccine, study finds

A new study by researchers in Jerusalem indicates that while specific antibodies to the virus are present in both serum and ovarian follicles following infection or vaccination, there is no apparent adverse effect on follicular function as a result.

High antibody and inflammatory mediator levels may predict severe COVID-19

A new study reports on biomarkers could help predict the progression of the viral illness to dangerous levels early enough to enable timely intervention.

ACE2 homology in laboratory and wild animals

A new preprint research paper posted to the bioRxiv server describes the conservation of an important receptor gene for the virus among several animal species that live in close contact or proximity to humans.

Study finds no evidence of SARS-CoV2 transmission by breast milk

Some studies have reported the detection of SARS-CoV-2 RNA in breast milk from women who were recently infected with the virus. A new study explores the relationship between viral RNA and infectious virus to clarify the occurrence of vertical transmission through breast milk.

Does natural infection with SARS-CoV-2 offer more protection than a vaccine against new variants?

A new study demonstrates that vaccines may be less effective at countering the newer SARS-CoV-2 variants compared to natural infection.

Serum and breast milk SARS-CoV-2 antibodies correlated in vaccinated mothers

A new study shows the correlation between serum levels of antibodies to SARS-CoV-2 and levels in breast milk following the vaccination of lactating women with a vaccine based on mRNA technology.

Microrna-29 molecule controls brain maturation in mammals

A team led by scientists at the UNC School of Medicine identified a molecule called microRNA-29 as a powerful controller of brain maturation in mammals. Deleting microRNA-29 in mice caused problems very similar to those seen in autism, epilepsy, and other neurodevelopmental conditions.
