Robust passive and active immunity found in infants born to COVID-19 positive mothers

A new study provides evidence that babies born to mothers who were COVID-19 positive two or more months before delivery are protected by maternal antibodies, besides mounting a robust immune response in case they contract the infection in the perinatal period.

Pregnancy may increase the risk of COVID-19 severity

Against the background of the COVID-19 pandemic, the impact of SARS-CoV-2 infection in pregnancy has been a subject of much controversy. In order to help answer the question as to whether this infection causes significant harm in pregnancy, a new study, released as a medRxiv* preprint, reports on the disease outcomes of this infection in pregnant women.

Mechano-immunological response to SARS-CoV-2

In a recent study, researchers demonstrated a human organ-on-a-chip (Organ Chip) microfluidic model of the lung alveolus (Alveolus Chip) - that recapitulates the human alveolar-capillary interface with an air-liquid interface (ALI) and vascular fluid flow to understand the local triggers in the lung in vitro.

Stem cell therapy for COVID-19 and ARDS

In a review paper recently uploaded to the journal Biomedicine & Pharmacotherapy by Mahendiratta et al. (May 2021) the applicability of stem cells in treating severe SARS-CoV-2 infection is investigated, with regard to ARDS therapy.

Pfizer/BioNTech and Moderna vaccines induce T-cell immunity against SARS-CoV-2

Researchers in the United States have shown that the Pfizer/BioNTech and Moderna messenger RNA (mRNA) vaccines are effective at generating T-cell immunity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Pan-COVID-19 vaccine protects mice against SARS-CoV-2 variants

Researchers in the United States have identified short peptide sequences in the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that are immunogenic in a mouse model and may provide protection against viral variants.

Study reveals no negative effect of SARS-CoV-2 BNT162b2 vaccination on male fertility

Researchers analyzed the sperm parameters of males undergoing fertility treatment and found no effect from the BNT162b2 mRNA severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine.

Can the absence of evidence of in-school SARS-CoV-2 transmission be taken as evidence of absence?

Research by scientists at the University of Texas at Austin, the Santa Fe Institute, and Fractal Therapeutics suggests infection rates in the surrounding community are not a reliable measure for estimating the level of risk for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission in schools.

Scientists identify genetic mutation associated with exfoliation syndrome known to cause glaucoma

A team of researchers from the Agency for Science, Technology and Research's Genome Institute of Singapore and Bioprocessing Technology Institute, as well as Singapore Eye Research Institute, have identified a genetic mutation (functionally defective CYP39A1 gene) associated with exfoliation syndrome, the most common cause of glaucoma.

Increasing sodium and calcium levels in the bloodstream helps prevent deadly arrhythmias

Blood may seem like a simple fluid, but its chemistry is complex. When too much potassium, for instance, accumulates in the bloodstream, patients may experience deadly irregular heart rhythms.

Researchers identify mechanism of platelet hyperactivation in COVID-19 patients

A recent study conducted at the University of Pennsylvania and the Children’s Hospital of Philadelphia, USA, has revealed the mechanism of platelet hyperactivation in critically ill coronavirus disease 2019 (COVID-19) patients.

What happens in the first few days of SARS-CoV-2 infection?

New research, published in PLOS Biology, has evaluated SARS-CoV-2 infection in primary cultures of well-differentiated cells to determine how the virus affects the body and how the infection starts. Answers to these questions are essential to forming a general understanding of viral pathogenesis, which helps us develop effective prevention and treatment strategies for COVID-19.

Can SARS-CoV-2’s impairment of endothelium cause vascular disease?

The study, published in the journal Circulation Research, suggests that COVID-19 is not only a respiratory disease but also a vascular disease. It highlights how the virus attacks the vascular system, causing endothelial impairment.

COVID-19 in pregnancy does not significantly increase respiratory illness in newborns, says study

A new study published in the journal JAMA offers reassuring evidence that infants born to mothers with coronavirus disease 2019 (COVID-19), or even asymptomatic infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), have little increase in respiratory symptoms over babies born to uninfected mothers.

Could in vitro glycoengineering help produce better SARS-CoV-2 spike candidates for vaccine research?

A vexing problem in the development of vaccines has been the need to achieve the right glycosylation profile for the viral antigens. A new study, recently released as a preprint on the bioRxiv* server, shows how a sequential cell-free approach produced complex N-glycans from simpler types, in a one-pot reaction.
