Question
1.) After receiving a vaccine containing a particles from a dead virus (not able to infect cells) and an adjuvant, one would expect a person to have increased inflammation, NK cell activity and interferon secretion at the injection site. True or False, and why?
2.) If a person's Helper T cells were able to be activated and were able to clonally expand, but were unable to secrete cytokines, that person would be more susceptible to both bacterial and viral infections because of decreased reponses of Cytotoxic T cells and B cells. True or False, and why?
3.)A person suffering from AIDS and a person suffering from a primary immune deficiency could both have low numbers of CD4-expressing Helper T cells, but a person suffering from an autoimmune disease probably would not. True or False, and why?
4.)All of the macrophages in an otherwise healthy human are infected with a virus. The virus is able to use the macrophage's enzymes to produce more viral particles, but it does not kill the macrophages. Will the macrophage be able to activate Helper T cells, cytotoxic T cells, or both? Explain your answer. Be sure to include a description of the interactions between viral antigens, MHC molecules and TCRs found on the macrophage and/or T cells in your answer. True or False, and why?
Explanation / Answer
After receiving a vaccine containing a particles from a dead virus (not able to infect cells) and an adjuvant, one would expect a person to have increased inflammation, NK cell activity and interferon secretion at the injection site ------------> TRUE
Vaccination is an immunization procedure in which a person develops immunity particularly against a specific pathogen. Vaccines contain live attenuated or killed organisms that are injected to the person in a series. So, our body develops antibodies to those antigens and if that organism enters into our body, they readily attach the pathogen. During this process, initially our body generates inflammatory mediators and immune cells that also include NK cells and interferons. Vaccination is a type of acquired immunity.
