Chapter 1, Problem 3Q
Summary Introduction
To determine: The reason how some patients were infected with AZT-resistant strains of HIV-1 though they never received AZT.
Introduction: Acquired immunodeficiency syndrome (AIDS) is a life-threatening disorder that is caused by a retrovirus called human immunodeficiency virus (HIV). This is a life-threatening syndrome because the virus interferes with the body’s ability to fight against diseases by destroying T cells of the immune system.

Why have attempts to find a vaccine against HIV been unsuccessful?
Prior to the development of detection assay for HIV in the blood supply, HCV was used as a proxy. That is to say, any donated blood found to be contaminated with HBV or HCV was also assumed to be HIV positive as well. What do you think was the rationale behind the use of HCV as an indicator of HIV? Do you think this was a reasonable approach at the time?
According to the article which was written before the COVID-19 vaccine was created, when do people turn to magic? How can this tendency, which happens across cultures and throughout history, contribute to the current spread of the novel coronavirus and its variants?

- Which of the following is the most likely explanation for an individual who lacks CCR5 as a result of a homozygous defect in the CCR5 gene becoming infected with HIV? a. The mutated CCR5 genes reverted to the normal form, rendering macrophages susceptible to macrophagetropic HIV variants. b. The macrophage-tropic HIV variant entered host cells using CD4 alone. c. The viral nucleic acid alone was taken up by cells, as in cell transformation by bacterial DNA. d. The individual had received a transplant of HIV-infected cells expressing normal CCR5. e.

- This is a hypothetical scenario. A recently emerged virus has been transmitting and mutating rapidly in humans throughout the world. If a vaccine that stops transmission of all current circulating variants of the virus in humans is utilized and herd immunity is achieved throughout the world, would this essentially stop 1) further transmission of the virus; 2) further mutation of the virus, respectively? Why/why not? Please answer the question succinctly and in bullet points!arrow_forwardWhich 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.arrow_forwardA researcher performs an experiment where he infects 2 mice (Mouse A and Mouse B) with herpes simplex virus (HSV).

A day later, he checks the co-culture, but none of the infected spleen cells from Mouse B have been killed. What could explain this observation? a.Mouse B does not express the invariant chain (Ii) b.Mouse A and Mouse B express different MHC alleles c.Mouse A does not express TLR2/6 d.HSV immunoevasins block MHC-II expressionarrow_forward
