New antibodies target 'dark side' of influenza virus protein

March 1, 2024
Researchers have identified antibodies targeting a hard-to-spot region of the influenza virus, shedding light on the relatively unexplored 'dark side' of the neuraminidase (NA) protein head. The antibodies target a region of the NA protein that is common among many influenza viruses, including H3N2 subtype viruses, and could be a new target for countermeasures.

MIT scientists use a new type of nanoparticle to make vaccines more powerful

March 6, 2024
Many vaccines, including vaccines for hepatitis B and whooping cough, consist of fragments of viral or bacterial proteins. These vaccines often include other molecules called adjuvants, which help to boost the immune system’s response to the protein.Most of these adjuvants consist of aluminum salts or other molecules that provoke a nonspecific immune response. A team of MIT researchers has now sho
