A recent study published in the Journal of Experimental Medicine showed that dynamic, frequent host-pathogen interactions activate nasal innate immunity in children. Studies have reported heightened ...

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 ...

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

A team led by researchers at the University of Cologne has identified a protein called ANKIB1 that acts as a volume dial for the body’s frontline immune defenses, controlling how strongly cells ...

Detailed immune profiling in long-term care populations reveals that SARS-CoV-2 vaccines and infections drive powerful virus-specific responses while leaving lifelong common cold immunity largely ...

A vaccine usually trains your immune system to recognize one target. Here, the target is basically “anything that doesn’t belong in the lungs.

Have you noticed feeling under the weather lately? The changing seasons, sudden rains, or unexpected heatwaves might be more than just a nuisance for the body; they’re quietly affecting our health and ...

A new study led by University of Toronto researchers has shown that immune cells in the gut follow an atypical pathway to produce antibodies that provide long-term protection against viruses. The ...
