The next step to investigate potential interrupting factors to break the sides of the triangle, or whatever connects each of the vertices. Here, we demonstrate that O 3 exposure impaired the ability of microglia, the brains parenchymal immune cells, to associate with and form a protective barrier around A plaques, leading to augmented dystrophic neurites and increased A plaque load. Read the Anthrax Fact Sheet on the following 2 pages, then answer the questions below. This is represented with the disease triangle. Susceptibility and response to an agent are influenced by factors such as genetic composition, nutritional and immunologic status, anatomic structure, presence of disease or medications, and psychological makeup. 4.Inadequate sanitation systems, A young couple with a family history of cystic fibrosis meets with a nurse to ask about preconception testing using genetic markers for early identification of the disease to help them make childbearing decisions.
