Secondary infections caused by bacteria or viruses during hospital care remain a long-standing global challenge, despite ...

Bacteria can play established roles both as pathogens during infection but also as part of the host microbiota. The immune response to bacterial infection is a critical defence strategy protecting the ...

When food is scarce, stress hormones direct the immune system to operate in "low power" mode to preserve immune function while conserving energy, according to researchers at Weill Cornell Medicine.

Northwestern Medicine scientists have identified the cellular mechanisms that cause immune cells to differentiate and ultimately lose function during viral infection, findings that could improve ...

Researchers found that during calorie restriction, glucocorticoids reorganize immune responses, reducing energy-intensive T ...

The immune system’s first encounter with a virus or vaccine establishes a “starting template” that shapes its response to new variants, a phenomenon often called immune imprinting. A new study shows ...

A new longitudinal study provides critical insights into the intricate interplay between human immunity and viral evolution ...

Researchers at the University of Queensland (UQ) have identified how a common bacterium is able to manipulate the human immune system during respiratory infections and cause persistent illness. The ...

Herd immunity occurs when enough people in a group are immune to a specific infection that it cannot spread easily from person to person. Vaccination programs have been successful in creating herd ...

An encounter with a speeding car, a walk across an icy road, or exposure to germs: daily life comes with experiences that can potentially harm a person. Anticipating such threats and preparing for ...
