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 ...

Lingering inflammation from viruses like COVID-19 or HIV can take a lasting toll on the brain. New research shows exactly how specific immune system imbalances lead to memory lapses and slowed ...

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 ...

Innate immune sensors—known as pattern recognition receptors (PRRs)—detect specific molecular components of bacterial or ...

The oral microbiome is a high-impact interface between microbial exposure and host immunity, and growing evidence suggests it can shape inflammatory tone ...

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 ...

Virus-associated cancers are a significant and persistent global health challenge, providing unique insight into the relationship between chronic infection ...

A first-of-its-kind study led by the University of Oxford has successfully investigated human immunity against COVID-19 in people who already have antibodies against it. The results suggest that ...

Modified vaccinia Ankara-Bavarian Nordic vaccine-induced antibody responses declined more rapidly than mpox infection-induced antibody responses, with mean titres dropping below the seropositivity ...
