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, ...

When thinking about the immune system, most people think about B and T cells and how they can be trained to recognize pathogens, preventing re-infections. Besides this "adaptive" immune system, we ...

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 ...

The immune system can work in two ways: the innate immune system reacts to any foreign invaders that are identified by immune cells that look for such pathogens; but the acquired or adaptive immune ...

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 ...

Researchers have shown that innate immune training, also known as trained immunity (TRIM), leads to aggravated bone loss in experimental models of periodontitis and inflammatory arthritis. Clinical ...

Researchers at the University of Cologne and University Hospital Cologne have determined that the novel mRNA-based COVID-19 vaccines not only induce acquired immune responses such as antibody ...

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 ...

What keeps some immune systems youthful and effective in warding off age-related diseases? In a new paper published in Cellular & Molecular Immunology, USC Stem Cell scientist Rong Lu and her ...

Cervical health depends on immunity, gut balance and lifestyle choices. Experts explain how holistic practices, stress ...
