Through a process known as DNA methylation, tags or markers attach themselves to DNA in the immune cells. This "tagging" is likely to last between five and 10 years after people successfully lose ...

A new AI-based method reconstructs spatial information about where immune cells were originally located in an organ, even after these cells have been removed from the tissue and analyzed individually.

A study published today in Nature Communications describes how lymphatic endothelial cells assist in generating robust immune memory, offering new insights into how the immune system functions.

A commonly prescribed epilepsy drug has shown striking potential as a vaccine booster in a controlled human trial, more than ...

Macrophages are some of the body’s most potent weapons against invading cellular threats. Like immunological ‘Hungry Hungry Hippos,’ macrophages engulf and dispose of cancer cells or invasive ...

The immune system can be further classified into the innate and adaptive immune systems. Although innate myeloid cells, such as macrophages, generate a ‘trained’ immune response following antigen ...
