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, ...

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 ...

Our immune systems prevent and limit infections. They are a complex set of organs, cells, tissues and proteins that work together to protect our bodies from harmful invaders such as bacteria, viruses, ...

I am lying under a blanket, feeling rough, staring at a bowl of oranges. Every fibre of my being is urging me to devour the lot. I can hear my mum – and medical friends at university – insisting that ...

Researchers have discovered that mRNA-based COVID-19 vaccines have a persistent effect on the innate immune system. These mechanisms may help the human body to better protect itself against potential ...
