CCL21 protects tumor immune

Team: Polytechnic LausanneRevue: Science (U.S., March 2010)

The researchers studied tumor cells melanoma in mice. They identified that they secrete a protein: Chemokine Ligand 21 (CCL21, also known 6Ckine). This chemokine is expressed in lymph node-level to protect an autoimmune response by leukocytes.
CCL21 thus allows the tumor to evade the immune response, by "mimicking" a lymph node. This discovery could have impacts on long-term immunotherapy.
