Which of the following statement(s) about DNA vaccines is(are) NOT true? Check all that apply. A.) DNA vaccines are an example of "ex vivo" vaccination; cells are removed from the body, transfected with DNA expressing the antigen(s) of interest, and then the cells are returned to the body. B.) DNA vaccines can be used to immunize with multiple different antigens. C.) DNA vaccines only stimulate B cell responses. D.) DNA vaccines only stimulate T cell responses.

a) How virus vaccine, under immune system processes (via dendritic cells, T-Cells and B-Cells), can help people against real virus infection. b) Structure of SARS-CoV-2 and their entry process on host cells. Then, if you choose onetype of virus protein (spikes, nucleocapsid, membrane or envelope) should be used for vaccine,which is the best candidate? Why?
Which of the following is false when considering the CCR5Δ32 mutation? a) The mutation prevents the entry of HIV-1 into a T cell. b) The deletion that produced CCR5Δ32 caused a frameshift which extends the length of the protein product. c) CCR5Δ32 prevents infection by HIV-1 in homozygotes but only delays the onset of HIV symptoms in heterozygotes. d) The protein product produced by CCR5Δ32 is altered in such a manner that it cannot embed in the cell membrane.
Moderna and Pfizer vaccines for COVID-19 use mRNA to the Spike protein combined with lipids. Which of the following is/are advantages of this type of vaccine compared to an inactivated virus vaccine? Select ALL correct answers. a) The vaccine is more stable for transport. b) The vaccine does not contain the virus so it cannot give you COVID-19. c) The vaccine can be rapidly produced in a slightly different form to protect from variants of SARS-CoV-2. d) The vaccine does not need a booster.
a) What is “washing” in immunology? What types of interactions doeswashing interfere with? What molecules are used for effective“washing” in the immunology lab?b) Blocking is also a common feature of immunological assays. Why isblocking required?i. A student forgot to block their Western blot membrane beforeadding the secondary antibody. They continue and block themembrane after the secondary antibody step, assuming itdoesn’t matter which order the steps are completed in. Howwould this affect the results seen?ii. A student blocked their ELISA plate with 50 microlitres ofblocking buffer, although their coating, binding and detectionsteps were at 100 microlitres. How would this affect the resultsseen?

You work for a large biotechnology company that is studying viruses, vaccines, and small molecule inhibitors. You are asked to give an overview of cell signaling as it relates to the coronavirus and young adults. a) Describe cell signaling pathways (e.g., at least 3) that are likely manipulated during a coronavirus infection. In your description, include how the pathways are involved in antagonizing the host antiviral response.
According to Research and Development department analysisresults, it was concluded that a two-stage control strategy wasoptimal for antibody production. In the first stage, conditions wereoptimized for cell growth. In the second stage, conditions werechanged to halt cell growth. Please answer the following questions in 1-2 sentences. (a) Why did they choose this two-stage approach? (b) How did they cause the cells to shift from a growth phase to a quiescent (non-growth) phase? (c)Please discuss which factors influence the choice of bioreactor design for optimal antibody production (Hint: The production of antibody which is anchorage-dependentsystems from continuous cell lines can be accomplished usingseveral bioreactor configurations, each of which was designed tosatisfy differing operational, product quality, economic, andproduction scale requirements.)
