Tiny antibodies to fight the dangerous effects of opioids
UNIGE researchers have discovered molecules capable of limiting the side effects of opioids by blocking the receptor responsible for their action. Peer-Reviewed Publication Université de Genève image: NbE (red) binds the specific receptor responsible for opioid action (blue) and blocks off other small molecules (white/yellow/red).

HIV antibodies protect animals in proof-of-concept study
by National Institutes of Health Transmission electron micrograph of HIV-1 virus particles (red) budding and replicating from a segment of a chronically infected H9 cell (blue). Particles are in various stages of maturity; arc/semi-circles are immature particles that have started to form but are still part of the cell. Immature particles slowly change morphology into mat....

Chemists’ technique reveals whether antibodies neutralize SARS-CoV-2
by Anne Trafton, Massachusetts Institute of Technology Graphical abstract. Credit: ACS Central Science (2023). DOI: 10.1021/acscentsci.2c01471 Antibodies that can disarm a virus, known as neutralizing antibodies, are key to the body’s ability to fight off infection. MIT chemists have come up with a new way to identify these neutralizing antibodies in a blood sample, by analyzing how antibodies...

New research reveals clues to how antibodies get fine-tuned to fight infection
Researchers at the University of Alberta have uncovered new information about a cellular mechanism in the immune system that provides a critical step toward better understanding how antibodies evolve and improve in the human body. The antibodies our immune system produces need fine-tuning to reach maximum effectiveness. When a vaccine or pathogen is first introduced into our...
