Lymph nodes are located at the junction of lymphatic vessels in the body. Lymphatic vessels transport fluid containing antigenic material, dendritic cells (DCs), and inflammatory biochemicals from ...

Researchers have uncovered a sieve-like structure in lymph nodes that regulates the transport of proteins and migration of white blood cells into lymph nodes. The discovery will provide new insights ...

Tumors, such as melanoma, release nanovesicles called exosomes (gray) that travel and lodge in the lymph nodes. There they corrupt the behavior of lymph cells. The lymphatic vessels (green) branch out ...

For the first time in decades, researchers have identified a new 'micro-organ' within the immune system - and they say it's an important step towards understanding how to make better vaccines. In a ...

Lymph nodes can contain large numbers of tuberculosis-causing bacteria and serve as long-term reservoirs of bacterial persistence, according to a study published November 1 in the open-access journal ...
