Specific immune cells, known as T lymphocytes, have to be activated so that the body can develop long-term protection against infections. Previously, it was believed that this process only took place in the lymph nodes and the spleen. Now scientists have discovered that T cells can also be activated in the liver -- via a much faster, more direct signaling pathway. The findings could lead to improvements in the formulation of vaccines.
