Good News: Scientists Discover Antibody which Prevents Coronavirus Infection

Femi Ashekun/

Building on research into antibodies which target the SARS coronavirus, scientists have identified one that blocks COVID-19.

According to a report published yesterday by Sky News, Scientists have discovered an antibody which prevents the coronavirus from infecting human cells in “groundbreaking research” which could lead to the development of new treatments.

The report says scientists from Utrecht University in the Netherlands, as well as the Erasmus Medical Centre and the company Harbour BioMed (HBM), built on research into the SARS coronavirus to identify a potential method of neutralising COVID-19.

They reportedly discovered that an antibody which prevents the SARS virus from infecting human cells could also block the novel coronavirus from infecting human cells too.

According to Sky News, the findings were contianed in a peer reviewed study published yesterday in the journal Nature Communications.

Testing their collection of antibodies on cultured human cells, researchers discovered one which binds to a specific part which is present in both SARS and the virus causing COVID-19.

The news medium suggested that the discovery could offer an initial step towards developing a fully-human antibody to treat or prevent the disease, which has infected more then 3.5 million people worldwide, and led to more than 247,000 deaths.

The neutralising antibody “has potential to alter the course of infection in the infected host, support virus clearance or protect an uninfected individual that is exposed to the virus,” Dr Berend-Jan Bosch, co-lead author on the study, reportedly said.

Dr Frank Grosveld, the study’s other co-lead author, was also reported to have said the discovery provided “a strong foundation for additional research to characterise this antibody and begin development as a potential COVID-19 treatment”.

“The antibody used in this work is ‘fully human’, allowing development to proceed more rapidly and reducing the potential for immune-related side effects,” he added.

The fully-human antibody is different from conventional therapeutic antibodies, which are often first developed in other species before being “humanised” so they can be transmitted to people.

It was developed using Harbour BioMed’s H2L2 transgenic mouse technology – effectively a mouse which has been genetically engineered to contain human genes, enabling researchers to develop “human” antibodies without testing them on living people.

Sky News quoted Dr Jingsong Wang, the chief executive of HBM, as describing the research as “groundbreaking”.
