The human body has several defense mechanisms. "Innate immunity" which is the routine protection present at birth. This immune system has three general components (first-line defenses, sensor systems, and innate effectors actions). In addition to the innate defenses, the human body has evolved a more specialized defense system of "adaptive immunity". This immune system develops throughout life as a result of exposure to microbes or certain other types of foreign material, and substantially increases the host's ability to defend itself. White blood cells (or leukocytes) are a major component for both "innate and adaptive immunity". All blood cells, including red blood cells and platelets, are originated from the same cell type called a) found in the bone marrow, which is induced to develop into the various types of blood cells by a group of proteins called b). A variety of types of white bloods cells serve specific roles in the innate and adaptive immune system. There are three major types of white blood cells based on their roles in the innate and adaptive immunity, such as i) granulocytes (neutrophils, eosinophils, basophils), ii) mononuclear phagocytes (monocytes, macrophages, dendritic cells), and iii) lymphocytes (B cell and T cell, natural killer cells). 1. What is in the blank a)? 2. What is in the blank b)? 3. "This" is one of innate effector actions and must be activated to function such as opsonization, lysis of foreign cells, and inflammatory response. What is this? 4. Fever is one of the innate effector actions and may reduce the availability of iron. If it is true, "why" is the iron availability important in body defenses?
True/False (2 pt), Definitions and Multiple Choice (2 pts) choose the best answer. 1. Reovirus has a dsRNA genome and was isolated by Jonas Salk. 2. interferon alpha/beta inhibits viral replication but neutrophils and Th cells are needed to clear the infection. 3. Chemists are trying to formulate better formula by adding antibodies. 4. exogenous pyrogens, like LPS, induce fever. 5. Whooping cough is caused by a gram positive coccus, Burnetella pertussis. 6. T cells originate in the bone marrow and mature in the thyroid. 7. LTB4 is an an abbreviation for a type of lung tuberculosis 8. The spleen is a primary lymphoid organ. 9. The best defense against infectious disease is a good offense (vaccines). 10. The lymphatic system is an open system of vessels. 11. The primary virulence factor in tetanus is endotoxin. 12. The adaptive immune response always involves T and/or B cells 13. The mannose receptor on macrophages binds to a carbohydrate. 14. Toll-like receptors are used to detect foreign pathogens and are only found in invertebrates. 15. A key difference between pathogenic and nonpathogenic m.o.'s is their ability to overcome innate immune defenses. 16. f-metleuphe is a common prokaryotic peptide sequence found throughout a bacterial protein sequence. 17. Rosalind Yalow received the Nobel Prize for developing a radioactive immunoassay.
