- with HIV, explain the mechanism of intracellular infection and the role of reverse transcriptase. What would you explain about the process? What is the significance of the CD4+ count? ( Discuss the meaning of various ranges of CD4 counts.) List 5 opportunistic infections AND describe data to suggest whether or not a patient has such an infection.arrow_forwardHow is the gp120 protein important to HIV and its ability to confound the immune system?arrow_forward1. Glycoproteins coat the outside of viruses; in particular they are important in helping HIV dock to our cells and also help the virus evade our immune system. Below is an image of the HIV transmembrane gp120 protein docking to human cd4 cells via the CXCR4 receptor. HIV-gp120 HIV CXCR4 Coreceptor CCR5 Coreceptor CD4 Receptor CD4 Cell a) i) Describe the general chemical interactions that might be involved in protein- protein interactions between the HIV gp120 protein and the human cd4 CXCR4 protein. Hypothesize what type of amino acid R groups you might find on the ii) exterior regions of each of these proteins, iii) and on the membrane bound portion of these proteins. b) The tertiary structure of gp120 is shown below. Please describe the protein (make sure to cover primary, secondary, and tertiary levels).arrow_forward

- A few years ago, Ebola was all over the news and it looks like it may return. A treatment method developed during the last outbreak involved patients who have recovered and then donated plasma to patients fighting an active infection. It is a remarkable treatment, with potential ethical dilemmas. Now, many people are attempting to turn to convalescent plasma treatments in lieu of vaccinations. There are articles on both Ebola and COVID-10 convalescent plasma use. Read the articles below, feel free to do more research on your own on the topic. Using the information in the lesson, the articles, and your own research, answer the following questions: 1) What are the potential ethical issues for donors, recipients, and medical providers? 2) What rules and stipulations should be applied to it's use, given that there is a limited supply for use in treatment? 3) Would you use this treatment for yourself or a loved one?
