DRAW IT Label IgE, antigen, and mast cell, and add an antihistamine to the following figure. What type of cell is this? Singulair stops inflammation by blocking leukotriene receptors. Add this action to the figure.
To determine:
The inflammation of singuliar blocks by blocking leukotriene’s receptors.
Introduction:
Type 1 hypersensitivity can cause immune response to the exposure of antigens. When IgE antibodies bind to the receptors on mast cells, then they will bind to the antigen. It causes degranulation of mast cells and the release of granules like histamine and leukotrienes. It leads to inflammation and breathing difficulties. This is blocked by giving singuliar drug.
Answer to Problem 1R
Correct answer:
A mast cell is given in this figure. An antihistamine is added to the mast cell; it blocks the inflammation.
Explanation of Solution
Diagram:
Leukotrienes attach to the receptors of mast cells; they cause inflammation. When a leukotriene receptor is blocked by singuliar, it stops inflammation. Mast cells play a role in autoimmune disorders. Singuliar (Montelukost) relieve the symptoms of hay fever, asthma, inflammation, and redness in skin. Singuliar mimics as leukotriene receptors.
Anaphylactic hypersensitivity mast cell releases histamine, leukotriene, and other mediators when it binds to the antigen and IgE antibody. When leukotriene receptors are blocked by singuliar, an allergic response does not occur.

- Figure 42.11 Which of the following statements about T cells is false? Helper T cells release cytokines while cytotoxic T cells kill the infected cell. Helper T cells are CD4+, while cytotoxic T cells are CD8+. MHC II is a receptor found on most body cells, while MHC I is a receptor found on immune cells only. The T cell receptor is found on both CD4+ and CD8+ T cells.arrow_forwardWhich pathway of complement activation is depicted in this figure?arrow_forwardPhagocytes bind to pathogen-associated molecular patterns (PAMPs) via: I selected opsonins, which is incorrect.

- Select the CORRECT alternatives about the complement system. The membrane attack complex is shaped like a needle to destroy the bacterial cell wall. The membrane attack complex has a pore shape. Opsonization is not part of the complement system and uses antibodies to attack viruses specifically. Opsonization uses antibodies to optimize phagocytosis.arrow_forwardDrop each label into the appropriate box, indicating which class of immunoglobulin is being described.
