Researchers present fragment-based computational design of antibodies that target structured epitopes

Antibodies are central to infection control and prolonged immunity. Key tools in biomedical research, antibodies are also used to diagnose human diseases and detect adaptive immunity to past infections with particular pathogens. While existing methods to discover and generate antibodies are successful, they also have important limitations, such as hard targets (short-lived, homologous, or unstable) […]

Researchers explore how N501Y mutation in SARS-CoV-2 increases viral transmissibility

Researchers at Erasmus University Medical Center in The Netherlands have explored how and why new variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19), have exhibited heightened infectivity. Study: Experimental evidence for enhanced receptor binding by rapidly spreading SARS-CoV-2 variants. Image Credit: Design_Cells / Shutterstock They suggest […]

The origin of SARS-CoV-2 furin cleavage site remains a mystery

The ongoing pandemic of coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has largely defied attempts to contain its spread by non-pharmaceutical interventions (NPIs). With the massive loss of life and economic damage, the only way out, in the absence of specific antiviral therapeutics, has been the development of […]

Freiburg immunologists decipher anti-cancer drug's mode of operation

Rituximab, an anti-cancer drug targeting the membrane protein CD20, was the first approved therapeutic antibody against B tumor cells. Immunologists at the University of Freiburg have now solved a mystery about how it works. A team headed by Professor Dr. Michael Reth used cell cultures, healthy cells, and cells from cancer patients to investigate how […]

Why Cryo-EM is Gaining Popularity in Structural Biology

By Shelley Farrar, MSc, BSc Cryo-electron microscopy, also known as Cryo-EM, is a technique for visualizing macromolecular structures which has been developed over the last two decades. It is a form of transmission electron microscopy which permits samples to be studied at cryogenic temperatures. Biological structures such as ribosomes and mitochondria from pathogens, ion channels […]
