    Spheres made from sugar polymers hide insulin-producing cells from attack by the immune system.

  • From Cancer Genomics to Cancer Drugs

    From Cancer Genomics to Cancer Drugs

    Lecture

    (58 min 46 sec) Genetic data from a large number of tumor types reveal commonly mutated genes and uncover connections between different types of cancer.

  • Cloning an Army of T Cells for Immune Defense

    Cloning an Army of T Cells for Immune Defense

    Animation

    (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.

  • AIDS and the HIV Life Cycle

    AIDS and the HIV Life Cycle

    Lecture

    (58 min 29 sec) The HIV life cycle, and how the virus destroys the immune system's ability to respond to infection.

  • AIDS: Evolution of an Epidemic

    AIDS: Evolution of an Epidemic

    Lecture

    Why has it been so hard to develop a vaccine against HIV? How are new medicines revolutionizing AIDS treatment? Can AIDS be cured?

  • CTL killing a target cell

    CTL killing a target cell

    Clip

    (1 min 17 sec) Video microscopy of a cytotoxic T lymphocyte in action.

  • Antigen presentation and CTL

    Antigen presentation and CTL

    Animation

    (2 min 34 sec) How a cell infected by a virus signals cytotoxic T lymphocytes to kill the cell before the virus replicates and spreads.

  • 2000 and Beyond: Confronting the Microbe Menace

    2000 and Beyond: Confronting the Microbe Menace

    Lecture

    (57 min 36 sec) In four presentations, Donald E. Ganem, MD, and B. Brett Finlay, PhD, discuss the latest advances in understanding how pathogens invade the body and how this knowledge is leading to the development of new therapies. They also explain how new infectious diseases are recognized and how epidemics arise.

    How the Host Avoids "Friendly Fire"

    Lecture

    (58 min 30 sec) Normally the trillions of lymphocytes in the human body do not attack their host.
