What Is The Function Of Lymph Nodes?

If we imagine our immune system to be a police force for our bodies, then

previous work has suggested that the Lymph nodes would be the best candidate

structures within the body to act as police stations -- the regions in which the

immune response is organized. However, researchers now suggest that lymph nodes

are not essential in the mouse in marshalling T-cells (a main immune foot

soldier) to respond to a breach of the skin barrier. This result is both

surprising in itself, and suggests a novel function for the liver as an

alternate site for T-cell activation.
