Open Yale CoursesBENG 100: Frontiers of Biomedical EngineeringLecture 8 - Cell Communication and Immunology (cont.)<< previous session| next session >>Overview:Professor Saltzman continues his discussion of cell communication in the body, extending the description tothe nervous and immune system. Professor Saltzman describes the mode of signal transmission in neurons:action potential in the axon, and neurotransmitter release at the synaptic cleft. He also introduces elements ofthe innate and adaptive immune system. The adaptive immune system is presented as a host/foreign antigenrecognition system involving immune cells (T, B, and macrophages), antibodies, and the majorhistocompatibility complex 1 and 2. Immune response by cytotoxic T cells, T helper cells, and B cells toantigen recognition are discussed in detail.
