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, ...

As we age, the immune system gradually declines in function, leaving the body more vulnerable to disease. Scientists have discovered a new way to rejuvenate a key component of immune function, ...

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 ...

Using single-cell epigenomic profiling of immune cells from 110 individuals, researchers show that genetic variation and ...

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.

The idea of turning back the clock on the immune system has moved from science fiction to a concrete experimental strategy. A ...
