Adapting biological research and development to COVID-19

In this interview, News-Medical talks to Dr Yuning Chen, about the work he does with Sino Biological and how they have adapted their research & development to the COVID-19 pandemic.

SARS-CoV-2 evolution promoted by long-term infection in patient with B cell depletion

A new study published on the medRxiv* preprint server focused on a patient with a persistent symptomatic viral infection for over a year. Researchers amplified sub-genomic transcripts for the E gene (sgE) using nasopharyngeal samples of the patient infected with SARS-CoV-2 over the course of 335 days.

Enisamium shows potential as antiviral therapy for COVID-19

Researchers studied the effect of enisamium on the growth and proliferation of Caco-2 and normal human bronchial epithelial cells.

Convalescent plasma is "futile" as COVID-19 treatment for critically ill patients, trial shows

In the earliest days of the COVID-19 pandemic, the medical community turned to a century-old treatment: Take blood from recovered patients and give it to the sick.

Prevalence of adaptive and prolonged infections’ mutations in receptor-binding domain of SARS-CoV-2 spike protein

A new study used the available nucleotide sequence data on the NCBI COVID-19 database and estimated the global prevalence of adaptive and prolonged infections' mutations in the RBD of the S protein.

Enveloped virus-like particle based vaccines potentially broaden immunity against SARS-CoV-2 variants

A new preprint describes promising results with a novel vaccine candidate designed to improve the breadth of neutralization.

Comparison of Pfizer, Moderna, J&J, AZ vaccines for neutralization titer, against Delta and other variants

Is one COVID vaccine better than the other? Four current vaccines — Moderna, Pfizer-BioNTech, Johnson & Johnson, and AstraZeneca — are highly effective against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), but a new medRxiv* study suggests the level of protection varies.

Chronic COVID-19 and divergent variants of SARS-CoV-2

A new study discusses the isolation of two variants of concern (VOCs) from an immunocompromised COVID-19 patient.

27 Sep 2021

A new SARS-CoV-2 variant (B.1.1.523) capable of escaping immune protections

A new study describes a new variant that possesses a novel combination of various concerning mutations at the spike region.

27 Sep 2021

People with natural immunity and subsequent mRNA vaccination can neutralize viral particles capable of resisting vaccine-induced antibodies

New research suggests SARS-CoV-2 spike protein substitution mutations can create a replication-defective viral particle that makes the virus resistant to vaccine-induced antibodies.

Decline in SARS-CoV-2 neutralizing antibodies and unique cytokine profile in severe COVID-19 patients

A new study has focused on antibody levels and cytokine profiles of COVID-19 patients with mild symptoms, pneumonia, and severe pneumonia.

21 Sep 2021

Failures and findings from randomized clinical trials in COVID-19 convalescent plasma

Researchers complete an extensive search on previously published studies to understand the efficacy of convalescent plasma in treating COVID-19.

Characterizing the flexibility of SARS-CoV-2 variant of concern spike proteins

A novel protein modeling method assesses changes to the conformation of the SARS-CoV-2 spike protein that have been encountered by mutation.

Convalescent plasma shows no benefit in hospitalized COVID-19 patients

A new paper describes the results of a randomized controlled trial of CP in adult COVID-19 patients on oxygen when used within 12 days of the onset of respiratory symptoms.

Study identifies broadly neutralizing antibody panel against SARS-like viruses

A recent study describes 40 broadly neutralizing antibodies from two individuals with a history of COVID-19 who were recently immunized against the virus.

Convalescent plasma does not reduce risk of intubation or death for COVID-19 hospitalized patients

A major study has found that convalescent plasma does not reduce the risk of intubation or death for COVID-19 patients.

Highly neutralizing human convalescent plasma reduces lung inflammation in SARS-CoV-2-infected macaques

A new study reignites the debate regarding the therapeutic utility of convalescent plasma in treating others with the COVID-19.

Implications of persistent SARS-CoV-2 infection in patients with lymphoid malignancies

In a recent study, scientists attempt to understand persistent COVID-19 and its implications in patients with hematologic malignancies.
