Novel polyclonal antibody XAV-19 efficiently neutralizes UK and South African SARS-CoV-2 variants

A promising new study reports on the high neutralizing efficacy of a polyclonal swine antibody against SARS-CoV-2, the pathogen responsible for the novel COVID-19. By demonstrating the ability of this antibody to neutralize all currently circulating viral variants, the study suggests that it is ideal for development as a new and very effective therapy for COVID-19.

70% of SARS-CoV-2 infected in Wuhan still have IgG antibodies

The coronavirus disease (COVID-19) first emerged in late December 2019 in Wuhan, China. Though it has been more than one year since the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was reported, it is still unclear how long the antibodies persist in those who have recovered.

Researchers determine key protein structure that may lead to effective treatments for schizophrenia

Glycine is the smallest amino acid - one of the building blocks of proteins. It acts also as a neurotransmitter in the brain, enabling neurons to communicate with each other and modulating neuronal activity.

UCI receives $4.2 million grant to study sporadic inclusion body myositis affecting aging adults

The National Institute of Arthritis and Musculoskeletal and Skin Diseases has awarded UCI a 5-year, $4.2 million grant to study sporadic inclusion body myositis (sIBM), which affects aging adults causing asymmetric muscle weakness and severe disability. The disease is currently untreatable and poorly understood.

FDA authorizes use of Symbiotica COVID-19 Self-Collected Antibody Test System

The U.S. Food and Drug Administration today announced it has issued an emergency use authorization for the Symbiotica COVID-19 Self-Collected Antibody Test System, the first antibody test authorized for use with home collected dried blood spot samples.

Researchers identify a novel SARS-CoV-2 variant (A.VOI.V2) in southern Africa

Scientists recently explored the transmission dynamics of currently circulating variants of SARS-CoV-2 in a southern African country. By analyzing the genomic sequences of these variants, they have identified a novel SARS-CoV-2 variant with multiple spike mutations. They have temporarily designated the variant A.VOI.V2.

Study suggests T-cells don't determine survival in severe COVID-19

In the study, which appeared on the pre-print server medRxiv, the team found that when the monkeys were reinfected, the T cell-depleted animals showed anamnestic immune responses, the enhanced reaction of the body's immune system to an antigen that is related to an antigen previously encountered.

Novel hydrogel-based vaccine formulation shows high efficacy against SARS-CoV-2

A fascinating new preprint research paper posted to the bioRxiv* server discusses impressively high neutralizing responses elicited with a single dose of a novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine formulation, which could help turn the tide of the current pandemic if validated.

New nanoparticle SARS-CoV-2 vaccine confers robust protection with single dose after two weeks

In a methodologically ‘state-of-the-art’ approach, US researchers have developed a protein-based nanoparticle vaccine against coronavirus disease (COVID-19), with a swift generation of antibodies and the potential to protect individuals who cannot receive other COVID-19 vaccines for medical reasons. The research is posted to the bioRxiv* preprint server.

Chemical inhibitor can reduce SARS-CoV-2's ability to infect host cell lines

James McKerrow, MD, PhD, dean of the Skaggs School of Pharmacy and Pharmaceutical Sciences at University of California San Diego, has long studied neglected tropical diseases -- chronic and disabling parasitic infections that primarily affect poor and underserved communities in developing nations.

Study finds CD8+ T cell responses detect all major SARS-CoV-2 variants

There have been concerns that several SARS-CoV-2 variants have mutations that allow them to evade the immune system. A new study published in the Open Forum Infectious Diseases suggests otherwise. Led by Aaron AR Tobian of Johns Hopkins University School of Medicine, results showed that except for one from the B.1.351 variant, CD8+ T cells showed a broad response to all SARS-CoV-2 variants.
