  • Cloning an Army of T Cells for Immune Defense

    Cloning an Army of T Cells for Immune Defense

    Animations

    (4 min 21 sec) View the animation to see how one type of immune cell—the helper T cell—interprets a message presented at the surface of the cell membrane. The message is an antigen, a protein fragment taken from an invading microbe. A series of events unfolds that results in the production of many clones of the helper T cell. These identical T cells can serve as a brigade forming an essential communication network to activate B cells, which make antibodies that will specifically attack the activating antigen.

  • Dengue Virus Enters a Cell
