Innate immunity constitutes the body’s first line of defence against invading pathogens. This ancient, evolutionarily conserved system is activated within minutes of encountering foreign agents, ...

Our immune system is much older than we think. Long before dinosaurs existed, early life forms had developed a powerful ...

Ocular infections and related inflammatory disorders are important causes of visual morbidity worldwide and may arise from viral, bacterial, fungal, and ...

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, ...

Innate lymphoid cells, which curiously behave like T cells even though they don’t recognize specific antigens, show promise as a potential cancer therapeutic. In the years that followed, other groups ...

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 ...

SARS-CoV-2 has an enzyme that can counteract a cell's innate defense mechanism against viruses, explaining why it is more infectious than the previous SARS and MERS-causing viruses. The discovery may ...

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 ...

We sometimes hear about the benefits of “boosting” our immune system, but what we really want to do is support our immune system on an ongoing basis. People often think of the immune system as ...

Cancer immunotherapies, including cancer vaccines, harness and amplify the immune system’s natural ability to detect and attack cancer cells. In this illustration, immune T cells (pink) attach to a ...

When the first cells appeared on Earth approximately 3.8 billion years ago, viruses were already here to greet them. Ever since, viruses have been devising ways to infect cells, and cells have been ...
