BSC 1005 Lecture Notes - Lecture 1: Aids, Histamine, Adaptive Immune System
Document Summary
Pathogen, antigen, antibody, antibiotic, allergen, immunity, immunoglobin, immunization, Most animals have immune systems that resist disease. The disease resistance provided by these systems is called immunity. Antigen: any agent recognized as foreign to the body. triggers an immune response. Antibodies help fight the pathogens all preceded by ig (immunoglobulin) ex. Iga is found in saliva and mothers milk. Igm: first antibody made by the newborns and the first made during an infection. Metabolic product of certain microorganisms that kills or inhibits the growth of other microorganisms. can help in removing pathogens in our own body. Immunization / vaccination involves introduction of vaccine that is made from killed or weakened bacteria or viruses. An allergy is a secondary immune response to a normally harmless substance. Exposure triggers production of certain antibodies, which release histamines. local inflammatory response results. Transfusion / transplant rejection: most transplant recipients are given drugs to suppress their immune system.
