Measles virus can cause giant cell pneumonia without a rash in children who have an underlying disease
- Humoral responses
- Induction of interferon
- Natural killer cells
- Phagocytic activity of macrophages
- T lymphocytes
Step by step
Solved in 3 steps
- Which of the following is a mechanism by which antibodies help rid the body of invading microbes? Agglutination whereby the bacteria are clumped together. Identifying viruses for elimination by NK cells Non-antibody dependent activation of complement Autoimmune diseasewhich of the following is a chemical defense found on all epithelial surfaces of the body? Lysozme antibodies tearsWhat is the role of histamine in inflammatory response? Name few drugs which reduce the symptoms of allergy.
- Click and drag each characteristic into the appropriate category based on the lymphocyte it describes. Inhibit multiplication and cytokine secretion by other T cells Only T cells that play a role in nonspecific defense Carry out the attacks on foreign cells Effectors of cellular immunity Thought to be important in preventing autoimmune diseases Promote the action of Descended from cytotoxic Limit the immune response cytotoxic T cells T cells Regulatory T Cells Helper T Cells Memory T Cells Cytotoxic T Cells ext> ( Prev 49 of 83What is the role of interferons in the immune response? They stimulate the production of antiviral proteins They stimulate the release of IgM. They establish memory cells for future exposures. They increase body temperature.This cell type is thought to initiate the demyelination associated with MS T cell Microglial cell Astrocyte Natural killer (NK) cell Oligodendrocyte Macrophage B cell
- Which is not a second-line, non-specific defense? inflammation IgA on mucous membranes antimicrobial proteins feverProtection is given to children before they catch a disease. They are given an injection of virions treated with formaldehyde to make them unable to cause infection, the antigen remains intact. What type of immunity is this? natural active natural passive artificial active artificial passiveThe antibody-antigen complex activates which arm of the Complement system properdin pathway classical pathway alternative pathway lectin pathway
- Complement can lead to the formation of the MAC which essentially lyses the target cell. Name another way complement leads to the destruction of the target cell and the molecules involved.List 3 things that helper T cells do:Write TRUE is the statement is True, otherwise write FALSE and explain why the statement is False. The complement system involves a set of genes that distinguish foreign cells from body cells. The alternative complement activation pathway involves the cleavage of C5 to form C9. The type of interferon present late in an infection is gamma interferon. Interferons cause muscle aches, chills, and fever. Toll-like receptors act to cause phagocytic chemotaxis. Lymphocytes are large agranulocytes. Opsonization occurs when a phagocyte’s pseudopods surround a microbe and fuse to form a sac. Defensins are antimicrobial peptides of the first line of defense.
