During infection, reversible switch permits flexible formation of memory T cells, long-lived blood cells that can remember pathogen encounters and respond upon reinfection. Unexpected findings have ...

Kathleen Abadie was funded by a NSF (National Science Foundation) Graduate Research Fellowships. She performed this research in affiliation with the University of Washington Department of ...

The endoplasmic reticulum (ER) is a crucial organelle present in eukaryotic cells, including human cells. The ER plays a vital part in making sure proteins are properly constructed, and that they get ...

The immune system responds to an infection by producing antibodies that recognize and bind to the cell surface of the pathogen, thus marking it as an intruder and triggering an immune response. For ...

For years scientists have puzzled over why the intracellular pathogen Salmonella is able to survive — and thrive — in human and animal tissues, even within otherwise hostile cells that are part of the ...

The body defends itself against pathogens by depriving them of vital iron. However, this strategy doesn’t always succeed against Salmonella. Researchers at the University of Basel have discovered that ...

Scientists have discovered that the most widely-used class of antifungals in the world cause pathogens to self-destruct. The research could help improve ways to protect food security and human lives.

Skin shields our bodies from the world’s dangers, but sometimes, with a nick or a bump, that barrier is breached. That’s when pain- and itch-sensing nociceptor neurons jump to action, transmitting ...

Dynabeads are microscopic magnetic spheres which scientists use to isolate certain types of cells and proteins. Now, MIT researchers are developing a method of using the beads to quickly spot ...

This movie shows a single naive CD8 T cell. a type of white blood cell involved in immunity activating in response to stimulation through the T cell receptor, with a yellow fluorescent reporter ...
