New research zeroes in on a unique group of immune cells that could transform how we treat—and possibly prevent—severe food allergies like peanut and shellfish.

Inside cells, two important enzymes act like small central regulatory hubs: dipeptidyl peptidase 8 and 9—DPP8/9 for short. Among other things, they regulate inflammatory reactions and influence ...

The immune system must be able to rapidly target invaders such as viruses while avoiding innocuous stimuli, or allergies may develop.

But for approximately 30 million Americans with food allergies—including 4 million children—immune cells mistakenly identify ...

Our gut is constantly exposed to a wide variety of foods, and the gut microbiome helps the immune system learn what's harmful ...

Researchers found that a small population of immune cells in the mouse intestine prevents allergic responses to food, suggesting that targeting such cells therapeutically could potentially lead to a ...

Immunologists break down the options for treating seasonal allergies depending on symptoms and severity. They share the most ...

DNA strand displacement circuits are inching closer to becoming cellular machines. Scientists are finding ways to make these programmable nanodevices stable and functional inside living cells. If ...

The electric skin cell signals, which move at glacial pace compared to those in nerve cells, may play a role in initiating healing.

and treat autoimmune disorders—in which the body's immune system attacks its own cells—by tamping down such reactions.

For roughly one in every hundred people, food containing even the smallest amounts of gluten can deliver a gutful of hurt and ...

Study in mice identifies essential immune cells in the intestine that help to prevent unwarranted reactions to harmless food allergens.
