Question
Chapter 35, Problem 10TYU
Summary Introduction
To determine:
The feasibility of treating septic shock with the drug that blocks the TLR signaling using mutated mice that has mutation that cause the inactivation of the TLR gene and purified LPS.
Introduction:
TLR are the toll like receptors that are involved in the septic shock of the body that is induced by the lipopolysaccharides (LPS) of the gram negative bacteria when it is introduced into the blood. The TLR are the reason for the septic shock.

SCIENTIFIC INQUIRY A major cause of septic shock is thepresence of lipopolysaccharide (LPS) from bacteria in the blood.Suppose you have available purified LPS and several strains ofmice, each with a mutation that inactivates a particular TLRgene. How might you use these mice to test the feasibility oftreating septic shock with a drug that blocks TLR signaling?

- An experiment tested the hypothesis that exposure to pesticides decreases immune function in tadpoles. The researchers raised tadpoles in groups, in containers of the same size in a room with consistent temperature and lighting. They exposed some tadpoles to no pesticides, some to low pesticide levels, and some to high pesticide levels, and then measured the density of white blood cells (immune cells) in the tadpoles. Part a: The researchers used a(n) ______________ experiment to show the effects of pesticides on tadpoles.

Analyze the data provided and answer the following: a) Compare your body’s response to antigen “A” both times you were exposed. Describe at least two ways in which the body’s response is different. b) Why might your body’s second response to “antigen A” have been so different? What changes may have occurred to your immune system?arrow_forwardHuman immune system During the inflammatory response, histamine plays a key role in causing capillaries to become more permeable to phagocytic cells such as neutrophils. Antibodies directly kill bacterial cells by activating cell death programs that lead to apoptosis. Interferons are signaling molecules produced by bacteria that block (or interfere) with the ability of plasma cells to release antibodies.arrow_forward
- Immune systems of animals are very complex. For an animal's immune system to work properly, certain cells must be able to recognize other specific types of cells, so that they can bind to and communicate with them. These types of interactions allow an immune system to decide if and when to launch an immune response. For example, dendritic cells must be able to recognize and interact with T-cells, but they do not need to recognize adipocyte cells. Which of the following describes a difference between T-cells and adipocyte cells that would allow dendritic cells to recognize one, but not the other? A. Adipocyte cells must have a cell wall, while T-cells lack one. B. T-cells and adipocyte cells must have different types of lipids that compose their plasma membranes. C. Adipocyte cells must lack endoplasmic reticulum, while T-cells possess endoplasmic reticulum. D. T-cells and adipocyte cells must have some differences in the carbohydrates and/or…arrow_forwardLymph nodes are secondary lymphoid organs.
