The complement system is a key component of innate and adaptive immunity and therefore acts as a vital defense against invading pathogens. Deficiencies in the complement system are associated with ...

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 ...

The complement system has more than 50 soluble and membrane-bound proteins. In innate and adaptive immunity, complement is essential for eliminating foreign pathogens and apoptotic cells. It is also ...

Humans are protected by two branches of the immune system. Innate immunity provides built-in defense against widespread characteristics of bacteria and viruses, while adaptive immunity memorizes ...

A comparison between a healthy brain (left) and a brain severely affected by Alzheimer’s disease (right). Alzheimer’s leads to significant shrinkage and loss of brain tissue, reflecting the damage ...

Immunotherapy is increasingly becoming standard therapy in cancer, with technology, such as checkpoint inhibitors and cell therapy, raising the efficacy bar in many forms of the disease. But the ...

Population bottlenecks caused by stark population loss due to illness or habitat destruction caused mammals' disease immunity to decline, according to a new study led by computational biologists in ...

Bacillus Calmette-Guérin (BCG) is one of the world’s oldest and most widely used vaccines. It was developed in the early 20th century to provide protection from tuberculosis. Surprisingly, this ...

The BCG vaccine protects against tuberculosis, but by inducing trained immunity it also protects against many more respiratory infections. International research led by the Radboudumc shows how this ...

Researchers aimed to track the clinical course and characterize the global and COVID-specific immunity in the blood of individuals with long COVID. Two recent studies have analyzed the blood of ...
