Our immune system plays an essential role in protecting us from diseases, but how does it do this exactly? Dutch biologist Suzanne van Helden discovered that before dendritic cells move to the lymph nodes they lose their sticky feet. This helps them to move much faster. Immature dendritic cells patrol the tissues in search of antigens. After exposure to such antigens they undergo a rigourous maturation process. During this maturation the dendritic cells migrate to the lymph nodes to activate T cells. Suzanne van Helden studied the adhesion and migration of both immature and mature dendritic cells...
