Novel research led by Brazilian scientists describes the immune system's reactions in detail in the first living patient to ...

The innate immune system serves as the body's first line of defence, rapidly detecting and responding to external pathogens and internal damage. Recent advances in the field have highlighted the ...

The relationship between inflammation and cancer represents one of the central paradoxes in modern tumor immunology. On one hand, chronic inflammation is a ...

Scientists generally agree that eukaryotes, the domain of life whose cells contain nuclei and that includes almost all multicellular organisms, originated from a process involving the symbiotic union ...

When pathogens attack the body, the innate immune system goes to work protecting against the invading disease. The innate immune system is the first line of defense. It detects precisely what the ...

Tissue-resident macrophages are crucial players in the immune system, acting as the first line of defense and maintaining tissue homeostasis by responding to various environmental challenges and ...

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 ...

A new review by Dr. Ruyuan Wang and an international team of researchers explores the complex interactions between the innate and adaptive immune systems, shedding light on regulatory mechanisms in ...

Researchers have observed rapid and distinct immune system changes in a small study of people who switched to a vegan or a ketogenic (also called keto) diet. Scientists closely monitored various ...

An immunologist imagines the body’s defense system as a team of unique, quirky characters, showcasing their essential roles.
