Researchers generate cutting-edge mouse models by engrafting human cells and tissue into the animals to better study the human immune system. Scientists have employed mouse models in immunological ...

During the recent Covid-19 pandemic, the rate of serious illness and death was jarringly high in older populations. Why? Weakening immune systems — as we age, we become more vulnerable to infections, ...

Vitamins and supplements like zinc and cod liver oil are often touted for their ability to boost your immune system, but Jeffrey Bland, the "father of functional medicine," says that's not actually ...

When food is scarce, stress hormones direct the immune system to operate in "low power" mode to preserve immune function while conserving energy, according to researchers at Weill Cornell Medicine.

Why does the same virus barely faze one person while sending another to the hospital? New research shows the answer lies in a molecular record etched into our immune cells by both our genes and our ...

You might know your immune system as the built-in, around-the-clock surveillance system primed to keep nasty germs out and swiftly kick to the curb any that do manage to sneak in. It’s a system primed ...

Antibodies, which recognize viruses and proteins that the body has encountered before, have long gotten most of the credit for giving the human immune system a memory. Now, researchers at the ...

A person’s menstrual cycle may affect their immune system’s response, causing fluctuations throughout the month. The menstrual cycle involves a series of changes in hormone levels and structures ...

If the COVID-19 pandemic has done one thing, it’s made us all more familiar with some of the important players in the immune system. Antibodies, B cells, and T cells are among the best known parts of ...

Recent studies have shown that even if you feel healthy and fit, your immune system could be aging quicker than you think, which could increase the risk of infections and immune-related disorders.
