Monoclonal Antibody News and Research

RSS

Monoclonal antibodies (MAbs) are produced from a single B cell clone and can bind to a single type of antigen binding site. MAbs are homogenous antibodies that cannot form lattices with monomeric proteins as they can bind to only a single epitope on the antigen. Developed in the 1970s, MAbs can be produced against any given substance. Thus they can be used to detect and purify any substance of interest. This has made MAbs a powerful tool of molecular biology, biochemistry, and medicine.

Males may have higher but more transient SARS-CoV-2 immunity than females post-infection

Adding another piece to the puzzle that is coronavirus disease 2019 (COVID-19) serology, a new study published on the preprint server medRxiv* in November 2020 suggests that males have stronger but more transient anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) protective immunity than females.

New drug reduces LDL cholesterol in patients with severe hypercholesterolemia

The investigational drug evinacumab reduced low-density lipoprotein (LDL) cholesterol--the so-called "bad" cholesterol--by 50 percent in patients with severe hypercholesterolemia whose condition is resistant to standard treatments, a phase 2 study from the Icahn School of Medicine of Mount Sinai and other global academic sites has found.

Bispecific sybodies show potential against SARS-CoV-2

As the search for effective antivirals against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues, a new study published on the preprint bioRxiv in November 2020 discusses the role of synthetic nanobodies or sybodies in neutralizing the virus by binding to its receptor-binding domain (RBD) on the spike protein.

Promising new antivirals target arboviruses and SARS-CoV-2: Nodosome inhibitors

A new study describes two promising small molecules that inhibit a host cell factor, called nucleotide binding oligomerization domain-containing protein 2 (NOD2), that inhibits the replication and spread of many arboviruses. This could lead to the development of broad-spectrum antivirals. The study's findings have been published on the preprint server bioRxiv*.

Novel super-activating macrophage receptor could explain hyper-inflammation in severe COVID-19

Immunity is a curious thing. While essential in protecting the body against invading pathogens and foreign antigens, it can also turn against the body and trigger destructive immunological processes. A new study published on the preprint server bioRxiv* in November 2020 reports on the role played by hyperactive macrophages in a range of acute and chronic hyper-inflammatory conditions.

UIC enrolls people into phase 3 monoclonal antibody clinical trial

Researchers at the University of Illinois Chicago are now enrolling people into a phase 3 clinical trial that will test if a monoclonal antibody treatment -- administered as a series of four shots -- will help protect uninfected individuals from acquiring or getting sick from COVID-19 after someone in the household tests positive for COVID-19.

COVID-19 study: Researchers recruit frontline workers to identify asymptomatic individuals

Fifteen hundred frontline workers are being recruited for a yearlong study to find what percentage are positive for the virus that causes COVID-19, what percentage become positive and whether the antibodies they produce protect them from reinfection.

MD65 IgG-YTE shows powerful post-exposure neutralization of SARS-CoV-2

A recent study published in the preprint server bioRxiv in October 2020 describes a reliable animal model to demonstrate the powerful capacity of human neutralizing mAbs directed against SARS-CoV-2 to prevent viral binding the host cell receptor and thus block infection. This indicates the lifesaving value of mAbs in severe COVID-19.

Researchers demonstrate potent antibody that fights against coronavirus

Scientists at Fred Hutchinson Cancer Research Center in Seattle have shown that a potent antibody from a COVID-19 survivor interferes with a key feature on the surface of the coronavirus's distinctive spikes and induces critical pieces of those spikes to break off in the process.

Spike protein of SARS-CoV-2 virus identifies and binds neuropilin-1 on human cells to infect them

Helping to explain what makes SARS-CoV-2 so capable of infecting human cells, researchers in two independent studies discovered that the virus's spike protein recognizes and binds a protein on the human cell surface called neuropilin-1.

3D imaging of SARS-CoV-2 infection in ferrets using light sheet microscopy

Researchers from the Friedrich-Loeffler-Institut, Federal Research Institute for Animal Health demonstrate the ability to detect severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in 3D tissue samples in ferrets. This will allow the detection of infection patterns in tissues and their interrelations.
