When our body is attacked by a pathogen, the pathogen has to find ways to evade our immune system and invade our cells to cause infection and illness. Reporting in Cell, researchers have now ...

Biologists have uncovered a new mode of communication inside cells that helps bacterial pathogens learn how to evade drugs.

Unexpected findings have emerged about how and when certain infection-killing white blood cells decide to form memories about their encounters with a pathogen. It has been known for decades that these ...

A team of immunologists at the University of Massachusetts Amherst has turned what we know about T-cells, one of the most important parts of the body's immune system, on its head, opening the door to ...

Using the parasite Toxoplasma as our representative pathogen, our work shows that some intracellular pathogens can apply physical forces during their entry into host cells, which then allow the ...

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 ...

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 ...

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 ...

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 ...

The itching, redness and swelling of an allergic reaction are caused by mast cells—the vigilant first responders of the immune system that spring into action with histamine-filled granules in response ...

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 ...
