New fluorescent probe can differentiate between B and T lymphocytes

Human blood contains several different components, including plasma, red blood cells (RBCs), white blood cells (WBCs), and platelets. Among these, WBCs are divided into numerous subcategories each with unique functions and characteristics, such as lymphocytes, monocytes, neutrophils, and others.

Researchers develop broad-spectrum SARS-CoV-2 RBD-based vaccine

In a recent bioRxiv* preprint, the large team of researchers evaluated a SARS-CoV-2 Spike receptor-binding domain ferritin nanoparticle protein vaccine (RFN) in a nonhuman primate challenge model. This study addresses the need for a next-generation, efficacious vaccine with an increased pan-SARS breadth of coverage.

Researchers identify SARS-CoV-2 antiviral compounds using protein assay

During the process of SARS-CoV-2 infection, once the virus penetrates the host cell, two open reading frames, ORF1a and ORF1ab, are translated. ORF1ab is responsible for the production of 16 nonstructural proteins (nsp). Several viral proteases such as 3CLpro and PLpro (papain-like protease) produce 1-16 nsps. A new study has been published in bioRxiv* preprint server, which deals with identifying drugs that are effective as PLpro inhibitors.

Zipper motif mediates SARS-CoV-2 spike trimerization within host cell membrane

A new preprint research paper posted to the bioRxiv* server describes the results of a nuclear magnetic resonance (NMR) study to determine the structure of the S protein transmembrane domain (TMD) and its membrane-proximal regions.

New algorithm can predict which genes cause cancer

A new algorithm can predict which genes cause cancer, even if their DNA sequence is not changed. A team of researchers in Berlin combined a wide variety of data, analyzed it with "Artificial Intelligence" and identified numerous cancer genes.

Inhibition of nsp14 methyltransferase as a potential antiviral target for SARS-CoV-2

Beyond vaccination, the broad-spectrum antiviral medication remdesivir has robust clinical evidence and is known as the best antiviral treatment to reduce severe COVID-19 infection in hospitalized patients. Research led by John F.X. Diffley of the Chromosome Replication Laboratory suggests a potential therapeutic target for treatment development is the viral RNA cap methyltransferases, essential for viral protein translation and immune evasion.

New technology shows encouraging results for treating osteosarcoma

A preclinical study led by researchers at The University of Texas MD Anderson Cancer Center shows an antibody-drug conjugate (ADC) targeting surface protein MT1-MMP can act as a guided missile in eradicating osteosarcoma tumor cells without damaging normal tissues.

Children less likely to spread SARS-CoV-2 than adults

A study conducted by researchers in Canada suggests that children may be less likely than adults to spread the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19).

Real-world evidence from Israel on VOCs and SARS-CoV-2 vaccine protection

A new study by Israeli researchers tested the hypothesis that certain SARS-CoV-2 variants of concern can overcome protection conferred by Pfizer-BioNTech (BNT162b2) mRNA vaccine and found evidence of increased breakthrough rates in vaccinated individuals. The research paper is currently available on the medRxiv preprint server.

Broadly cross-reactive antibody to SARS-CoV-2 RBD with robust resistance to mutational escape

A new study addresses an urgent need – namely, a therapeutic antibody directed specifically against a key SARS-CoV-2 antigen which is highly conserved among similar viruses, and is not easily bypassed by viral escape mutations.

Researchers provide ultrastructural details of SARS-CoV-2-infected respiratory epithelial cells

A team of scientists from the United Kingdom recently investigated the ultrastructural details of the attachment, entry, and budding processes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the human airway epithelium. They have used a highly differentiated air-liquid interface cultures of airway epithelium to thoroughly investigate the viral infection cycle. The study is currently available on the bioRxiv* preprint server.

Researchers work to develop dual antigen COVID-19 vaccine candidate

A new study has been published on the medRxiv* preprint server, which focuses on the development of a dual-antigen COVID-19' T cell' vaccine. This vaccine is developed based on the expression of both S protein and nucleocapsid (N) protein of SARS-CoV-2, using a next-generation human adenovirus serotype 5 (Ad5) platform.
