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 ...

Pioneering research led by Brazilians describes the immune system's reactions in detail in the first living patient to receive a genetically modified pig kidney transplant.

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 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 ...

A new study shows human immune systems differ across populations, raising new questions for medicine and global drug research ...

During the recent Covid-19 pandemic, the rate of serious illness and death was jarringly high in older populations. Why? Weakening immune systems — as we age, we become more vulnerable to infections, ...

Pathogens are ubiquitous and a constant threat to their hosts, which has led to the evolution of sophisticated immune systems in bacteria, archaea and eukaryotes. Bacterial immune systems encode an ...
