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 ...

Kimchi may do far more than add flavor to meals—it could help fine-tune the human immune system. A clinical study using advanced single-cell genetic analysis found that regular kimchi consumption ...

Every day, your immune system performs a delicate balancing act, defending you from thousands of pathogens that cause disease while sparing your body’s own healthy cells. This careful equilibrium is ...

The 2025 Nobel Prize in physiology or medicine has been awarded to a trio of scientists – two of them American and one Japanese – for unraveling how the immune system protects us from thousands of ...

As the body ages, so does the immune system. The immune system usually becomes less effective in older age, a process known as immunosenescence. This can increase the risk of: While you can’t prevent ...

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 ...

COVID-19 vaccines have been instrumental in reducing the impact of the pandemic, preventing severe illness and death, and they appear to protect against long COVID. However, some individuals have ...

Study reveals how our immune system transforms across a lifetime—unlocking the potential for predicting disease risk and optimizing health before symptoms appear. Resource: Integrating single-cell RNA ...

A growing number of American adults have weakened immune systems, which can leave them vulnerable to severe illnesses. By Knvul Sheikh Kaley Karaffa had just turned 28 when the reality of having a ...

The immune systems of men and women are known to display key differences. Men are, broadly speaking, more vulnerable to viral infections such as COVID and influenza. Women mount a stronger response to ...
