Taken together, these advances suggest that part of age-related immune decline is driven by specific, potentially reversible ...

In recent years, the field of immunology has increasingly focused on the role of glycolipids and sphingolipids in the differentiation and function of innate immune cells, such as macrophages, ...

Sepsis remains a leading cause of morbidity and mortality in critically ill patients, posing a major challenge to modern medicine. Despite advancements in treatment, the complexity of ...

Our immune system is divided into two main branches: innate and adaptive. Innate immune cells act as a first line of defense, quickly responding to invaders, while adaptive immune cells take a longer ...

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 ...

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 ...

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 ...

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 ...

The T-cell immune status of patients with conditions such as AIDS indicates disease progression. One way to evaluate T-cell immune health is to measure the proliferation of a patient's T cells in ...
