The breakthrough stems from new understanding of the signaling that takes place between different immune cells. Some of these patrol the body looking for signs of injury or disease, and then send ...

Human immunity is an incredibly complex system that has to be very carefully regulated by the body. We need our immune systems to be able to leap into action when our health is threatened by pathogens ...

Researchers have used a method of total-body imaging to measure and track the body’s immune response to viral infection. The method is a promising platform for studying human immunity in greater ...

Men and women experience immune aging differently, affecting disease risks. New data-driven research identifies key ...

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, ...

The average human has about 1.8 trillion immune cells. These cells patrol the body for bacteria, viruses, cancers, and other ...

Your immune system could weigh 1 to 1.2 kilograms and contain 1.8 trillion cells. “The immune system is a complex system comprising many different cell types with essential functions,” says Ron Milo ...

In the summer of 2008, in a cave nestled within Siberia’s Altai Mountains, Russian scientists unearthed a sliver of a finger bone. At first, the scientists assumed the fossil was from a Neanderthal — ...

An innovative gene-editing strategy could establish a new way for the body to manufacture therapeutic proteins—including ...

The human immune system is finely tuned to detect and destroy viral threats. But this same defense system can misfire. When ...
