Question
Chapter 35, Problem 5P
Interpretation Introduction
Interpretation:
The reason for the lack of response of mouse towards LPS should be determined.
Concept introduction:
The TLRs are the toll-like receptors that play an important role in the innate responses of the immune system. They are membrane-spanning, non-catalytic receptors. LPS is lipopolysaccharide that forms the outer membrane of the gram-negative bacteria.

Cold-Reacting Autoantibodies.
Most adult sera contain low titers of cold-reacting autoantibodies, most notably autoanti-I, autoanti-H, and autoanti-IH. These antibodies are usually IgM and of no clinical significance. They are troublesome in that they may interfere with the detection of significant antibodies, resulting in prolonged workups and delayed transfusions.Cold-reacting autoantibodies may be suspected when the screen cells, panel cells, and the autocontrol areall positive at the immediate spin phase and reactivity gets weaker or disappears with incubation at 37°C (Fig. 9–18).Certain cold autoantibodies activate complement and may be detected at the AHG phase when using complement-containing AHG reagent. These autoanti- bodies may be mistaken for weakly reacting IgG antibodies.Although it is not usually necessary to determine the specificity of the cold autoantibody, testing against additional cells may confirm its presence. Cord blood cells that lack the I antigen are of…

- Neutralizing antibodies are effective at preventing infection or toxicity mediated by pathogens or their toxic products. In fact, nearly all vaccines currently in use function by eliciting neutralizing antibodies. One example is the tetanus vaccine, in which neutralizing antibodies are generated against an inactivated form of the tetanus toxin (the tetanus toxoid). The most important feature of a neutralizing antibody is having high affinity for the antigen. being efficient at activating the complement cascade. having a high degree of multivalency, such as being a pentamer or hexamer of immunoglobulin monomers. being present at a high concentration in the circulation. 0 0 0 0arrow_forwardPart A (Short Response): You are developing a TGF-β agonist, but you don’t yet know which specific proteins it is signaling through.

- The small fragments of some complement proteins initiate a local inflammatory response. Recent studies using mouse models of pulmonary inflammation (a model for human asthma) have found that mice deficient in the C3a receptor have greatly reduced disease symptoms when challenged with inhaled preparations containing extracts of the fungal pathogen Aspergillus fumigatus. Specifically, the C3a receptor-deficient mice showed reduced influx of granulocytes and lymphocytes into the lung and reduced fluid in the lung after challenge. What is the explanation for these findings?arrow_forwardDescribe the pathway to how the adaptive immune system would become activated if a toxoid passed through a lymph node. Recall, lymph nodes have two types of resident antigen presenting cells. Start from one of the immune cells that detects the toxoid – be sure to include which immune cells are involved, what receptors are present, and what the outcome is. Then, start from the second immune cell that can detect the toxoid and follow the same format.arrow_forwardMammalian Toll-like receptors are activated by many different pathogen-associated molecular patterns. As a family, TLRs can recognize PAMPs associated with a broad array of different pathogens, including bacteria, viruses, and fungi. Patients with a specific susceptibility to herpesvirus infections have a defect in their ability to respond to viral nucleic acids using TLR-3, TLR-7, or TLR-9, even though these proteins are expressed in the patients’ cells. Analysis of the TLRs in macrophages and dendritic cells from these patients would likely show which of the arrangements in Figure below?arrow_forward
