Professor Saltzman continues his presentation on the topic of vaccine. First, Professor Saltzman describes the host immune response to pathogen recognition, in terms of immunoglobulin release, T-cell activation, and memory cell production. The production, distribution, and challenges involved in making of the Salk polio vaccine and the modern, oral polio vaccine are discussed. Professor Saltzman then talks about the range of bioengineering...more

Professor Saltzman talks about cell communication, specifically ligand-receptor interactions that are important in maintaining homeostasis in the body. Different types of receptors and ligands, the nature of their interactions and ways to apply this into developing drugs are discussed (eg. Aldopa, Taximofen, beta-blockers). Next, Professor Saltzman talks about kinases, phosphatases, cyclic AMP and the mechanism of switching protein states....more
Professor Saltzman continues his discussion of cell communication in the body, extending the description to the 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 of the innate and adaptive immune system. The adaptive immune system is presented as a host/foreign antigen recognition s...more
Professor Saltzman reviews the concept of gene therapy, and gives some examples of where this is applied. Methods to help deliver DNA into cells using viruses and cationic lipids are discussed, as a way to overcome some challenges in gene therapy. Next, Professor Saltzman gives a brief introduction into bacterial and mammalian cell physiology. He describes the different tissues in the body, the cell development/differentiation process, the...more
Professor Saltzman describes the processes of fertilization and embryogenesis. Professor Saltzman then talks about the definition and classification of different types of stem cells, where stem cells are found in the body, and the potential for use of stem cells in treating diseases. Some challenges in this type of therapy are also discussed. Finally, Professor Saltzman introduces the exponential equation for cell growth, dX/dt = e^Î¼t, an...more
Parts of a cell: nucleus, ribosomes, endoplasmic reticulum, Golgi bodies, mitochondria, chloroplasts, vacuoles, and vesicles.
