Document Summary

The study of the body"s defenses against infection. Non-self: bacteria, viruses, parasites: viruses, bacteria, fungi, parasites (unicellular or multicellular eukaryotes) Came up with the idea of a vaccine. Experiment: inoculated a boy with fluids from a cowpox pustule and then infected him with smallpox virus, but he did not develop smallpox. Innate: immediately available to combat a wide range of pathogens; no memory and not specific. Adaptive: specific immune responses to particular pathogens; lifelong protection and very specific. Overly active/misdirected responses: ie. allergies, asthma, and autoimmune disease (multiple sclerosis, crohn"s disease) Lag time response (cells have to be activated first) Lecture 2 & 3: innate and adaptive immunity. Cells: tumor cells, virally infected cells, donor cells (transfusions, transfusions) *ready for immediate action against pathogens, can initiate activation of adaptive: skin, respiratory tract, gastrointestinal tract, eyes/nose/mouth. Sebum: fat and debris from fat-producing cells that is deposited onto hair to come to the surface.
