Tiny antibodies naturally generated by llamas can be effective against COVID-19

As the fight against COVID-19 continues, scientists have turned to an unlikely source for a potentially effective treatment: tiny antibodies naturally generated by llamas.

Research demonstrates multivalent nanobodies overcome SARS-CoV-2 variant mutations

In a recent bioRxiv* preprint paper, researchers isolated anti-RBD nanobodies from llamas and “nanomice” (they engineered to produce VHHs cloned from alpacas, dromedaries and camels).

Inhalable nanobody shows potent anti-SARS-CoV-2 activity in vivo

Researchers have developed a stable and ultrapotent homotrimeric Pittsburgh inhalable Nanobody 21 (PiN-21) against SARS-CoV-2 infection in Syrian hamsters. They demonstrated the high therapeutic efficacy of this homotrimeric Nb, leveraging both intranasal and aerosol delivery.

Combination technique can toggle specific genes on and off

The genetic tool CRISPR has been likened to molecular scissors for its ability to snip out and replace genetic code within DNA.

Llama-derived nanobodies show neutralizing activity against SARS-CoV-2 variants of concern in vitro

A new study reports the development of nanoantibodies (nAbs) – also called or nanobodiesTM or single-domain antibodies – that effectively bind the SARS-CoV-2 spike protein from the ancestral Wuhan variant as well as the recently detected UK and South African variants.

How does the SARS-CoV-2 E484K mutation increase viral fitness?

How do mutations benefit SARS-CoV-2? To explore this, a team of researchers from China took a closer look at the physical interactions that occur between the proteins after viral mutation.

Pitt scientists develop fast, efficient technique for discovering tiny antibody fragments

By capitalizing on a convergence of chemical, biological and artificial intelligence advances, University of Pittsburgh School of Medicine scientists have developed an unusually fast and efficient method for discovering tiny antibody fragments with big potential for development into therapeutics against deadly diseases.

Nanobodies protect against SARS-CoV-2 variants in animal model

Nanobodies are a potential therapeutic strategy for treating COVID-19. While many previous studies report nanobodies active against SARS-CoV-2 in vitro, none have been evaluated via animal models' intranasal administration.

Alpaca nanobodies neutralize SARS-CoV-2 in vitro

A new preprint research paper posted to the bioRxiv server reports the development of highly effective neutralizing nanobodies targeting the viral receptor-binding domain (RBD), thus disrupting its engagement with the host cell angiotensin-converting enzyme 2 (ACE2) receptor.

Study shows how SARS-CoV-2 evades immune responses

In a recurring pattern of evolution, SARS-CoV-2 evades immune responses by selectively deleting small bits of its genetic sequence, according to new research from the University of Pittsburgh School of Medicine.

Crystal structures of nanobodies could aid the design of COVID-19 therapies

Researchers at the National Institutes of Health in Bethesda, Maryland, have shown how certain synthetic nanobodies bind to the agent that causes coronavirus disease 2019 (COVID-19) – a development that could help inform the design of therapies.

South African SARS-CoV-2 variant escapes antibody neutralization

Researchers in South Africa have conducted a study showing that the novel 501Y.V2 variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that has emerged in the country is able to escape the neutralizing antibodies that are elicited by previously circulating strains of the virus.

Researchers develop novel antibody fragments against SARS coronavirus-2

An international research team led by the University of Bonn (Germany) has identified and further developed novel antibody fragments against the SARS coronavirus-2. These "nanobodies" are much smaller than the classic antibodies used to treat US President Donald Trump, for example.

New publication describes DiosCURE’s multivalent single-chain antibodies to inactivate SARS-CoV-2

DiosCURE SE announced a publication in Science describing its core technology of multivalent single-chain antibodies with a unique molecular mode-of-action to inactivate SARS-CoV-2 virions. An international team led by scientists at the University of Bonn developed and characterized the lead candidates, which are exclusively licensed by DiosCURE.

Nanobodies have potential to be developed into a treatment for COVID-19

Researchers at Karolinska Institutet in Sweden have developed, in collaboration with researchers in Germany and the U.S., new small antibodies, also known as nanobodies, which prevent the SARS-CoV-2 coronavirus from entering human cells.

New approach to tame botulinum toxin for drug delivery

While rare, botulism can cause paralysis and is potentially fatal. It is caused by nerve-damaging toxins produced by Clostridium botulinum -- the most potent toxins known.

Non-toxic versions of botulism toxins can deliver therapeutic antibodies to treat botulism

Taking advantage of the chemical properties of botulism toxins, two teams of researchers have fashioned non-toxic versions of these compounds that can deliver therapeutic antibodies to treat botulism, a potentially fatal disease with few approved treatments.
