Study assesses impact of anti-SARS-CoV-2 convalescent plasma in COVID-19 disease

The current COVID-19 pandemic is still very much active in most parts of the world. In the absence of effective antiviral drugs or vaccines, scientists are studying the use of blood plasma from convalescent COVID-19 patients, banking on its neutralizing antibody content.

Protein profile in serum reflects COVID-19 severity

The wide range of manifestations of COVID-19 has continued to baffle investigators. Now, a new study published on the preprint server medRxiv in June 2020 shows that blood proteins in COVID-19 patients change over time, and these can possibly predict or reflect the severity of disease. More, they may present targets for treatment.

Immune response variations across the COVID-19 spectrum

A new study published on the preprint server medRxiv in June 2020 describes differences in the adaptive and innate immune response in mild, moderate, and severe COVID-19. This may mean that permanent immune responses occur only in patients who recover from severe COVID-19.

Researchers develop a noninvasive technology to destroy cancer cells

An international research team led by Dr. Tali Ilovitsh of the Biomedical Engineering Department at Tel Aviv University developed a noninvasive technology platform for gene delivery into breast cancer cells.

New study defines the transmission of COVID-19 from mother to child

UC Davis Health researchers took a critical step in defining the possible paths for the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) causing COVID-19 to get transmitted from the mother to her newborn baby. The mother to fetal transmission is known as "vertical" transmission.

A new approach to track down cryptic peptides

Almost all cells of the human body present fragments of cellular proteins on their surface, so-called human leukocyte antigens or HLA peptides, which play an important role in the immune response.

Discovery provides a potential target for infectious diseases immunotherapy

NIH investigators and colleagues have discovered that when the immune system first responds to infectious agents such as viruses or bacteria, a natural brake on the response prevents overactivation.

Study highlights the challenges involved in designing universal flu vaccine

Some common strains of influenza have the potential to mutate to evade broad-acting antibodies that could be elicited by a universal flu vaccine, according to a study led by scientists at Scripps Research.

New dengue virus serotype DENV3 has re-emerged in Singapore after three decades

Dengue infections are rising, even as public health authorities are battling to contain the spread of the coronavirus. Dengue virus serotype 2 (DENV2) had previously been the predominant serotype but DENV3 has re-emerged in Singapore after almost three decades.

Male COVID-19 patients produce more SARS-CoV-2 antibodies than women

Health officials in the United Kingdom urge male coronavirus survivors to donate blood, particularly its convalescent plasma component. This comes after a new study has found that men produce more antibodies, which could make their plasma a valuable treatment against the coronavirus disease (COVID-19).

UK announces research partnership with Atomwise to explore potential COVID-19 therapies

The University of Kentucky announced a research collaboration with Atomwise, an industry leader in using artificial intelligence (AI) for small molecule discovery, to explore potential COVID-19 therapies

First clinical trial in South Africa for Covid-19 vaccine begins

The first clinical trial in South Africa and on the continent for a Covid-19 vaccine was announced today, 23 June 2020, at a virtual press conference hosted by the University of the Witwatersrand, Johannesburg (Wits).

Research shows tongue microbiome could help diagnose heart failure

Microorganisms on the tongue could help diagnose heart failure, according to research presented today on HFA Discoveries, a scientific platform of the European Society of Cardiology (ESC).1

White Paper: Separation and characterization of viruses and antibodies

Postnova Analytics have published an informative new white paper that details how multi-detector Asymmetrical Field Flow Fractionation (AF4) and Electrical AF4 (EAF4) techniques are transforming the separation and characterization of viruses and antibodies.

Defective maintenance puts intestinal health in danger

In order to keep the intestinal mucosa and the entire organism healthy, intestinal epithelial cells have developed various protective functions involving a number of maintenance mechanisms that protect cells from stress.

SARS-CoV-2 induces broad T cell response in recovering patients

A new study published on the preprint server bioRxiv in June 2020 shows that T cell responses in COVID-19 patients are broader and more robust in severe disease and are explicitly directed against spike, memory, and ORF3a proteins.

Research shows females use anti-inflammatory T cells to maintain their blood pressure

In the face of a multipronged front to drive blood pressure up, including a high-salt diet, females are better able to keep their pressure down by increasing levels of a T cell that selectively dials back inflammation, scientists say.

8.5 percent of COVID-19 patients do not seroconvert

A new study published on the preprint server medRxiv in June 2020 reports on the use of inexpensive and accurate ELISA and rapid diagnostic tests (RDT) to identify the demographic and clinical factors that affect the antibody response in COVID-19 patients.

Scientists find COVID-19 antibodies fade quickly

Now, a new study shows that the levels of antibodies found in recovered coronavirus disease (COVID-19) patients declined sharply in just two to three months after infection for both symptomatic and asymptomatic patients.
