Segment from the program The Immunological System: Recognition, Attack, and Memory.
DVD Description
Our Immune System DVD starts by looking at external barriers to microbial attack such as the skin and mucus membranes and non-specific internal defenses such as macrophages, natural killer cells, and the inflammatory response. The program then delves into the immune response including the recognition of invaders by antibodies and T-cell receptors, the destruction of invaders by antibodies and cytotoxic T-cells, and the immunity conferred by memory cells. A discussion of how vaccinations work and current AIDS research concludes the program.
