To review:
The ability of antibody fragment F(ab’)2 to prevent the binding of rhinovirus with ICAM-1 receptors on the surface of the host cell and the ability of antibody fragment F(ab’)2 to facilitate microbial phagocytosis.
Introduction:
The antibody is comprised of two arms that are heavy and light chains. The heavy chains are attached by disulfide bonds. The antibodies have two regions, constant and variable regions. ICAM-1 or intercellular adhesion molecule 1 is one of the proteins encoded by gene ICAM-1. This gene encodes the glycoprotein present on the cell surface that expresses itself on the cell of the endothelium and immune system. It is one of the transmembrane protein and a member of a superfamily of immunoglobulins.

- 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.arrow_forwardWhat is the purpose of blocking the Western Blot membrane? A) To cover the membrane with a solution of proteins that serve as a substrate for secondary antibody binding B) To maintain target proteins in their native, non-denatured state C) To cover the membrane with a solution of proteins in order to reduce non-specific binding of the antibody to the membrane D) To enhance non-specific background staining through interactions with the proteins present in the blocking solutionarrow_forwardCan you compare and contrast the infection process of influenza and HIV? What are the specific molecules on the surface of each virus that directly interacts with the respective cellular receptor molecule? What is/are the specific molecules on the surface of the respective target cells that serve as the cellular receptors for these viruses respectively?arrow_forward
- Which of the following statement is false regarding the SARS-CoV-2 protease Mpro? a) Mpro catalyze the translation of viral RNA into polyproteins b) Mpro is an ideal drug target because its structure is largely conserved across the SARS-CoV family c) N3 is an irreversible inhibitor that block the substrate binding site of Mpro d) Mpro forms a dimeric structure and each protomer is composed of three domainsarrow_forwardDescribe an experiment in which you demonstrate that the pUL44 protein of Cytomegalovirus (CMV) localizes with phospho-H2AX (yH2AX). What reagent can be used to denote the cellular location of H2AX? Be sure to carefully describe your controls, as well as the expected results. What other technique can be used to validate the findings in this experiment? Explain.arrow_forward1) A) List 15 drugs (monoclonal antibodies can be used) used clinically to treat cancer in humans. These targets must be signal transduction pathway components. B) For each drug, list the specific protein targeted. C) For each drug, describe the efficacy of treatment (i.e. what is the success rate in life extension) as well as appropriate cost of treatment whether it be per round or an average annual cost.arrow_forward
- D) RNA polymerase 29. In lecture, we discussed some of the new platforms for COVID-19 vaccines. Adenovirus-vector vaccines and mRNA vaccines both involve the introduction of pieces of DNA or RNA, respectively. In both cases, the objective is to ... A) enable the human body to produce the SARS-coV-2 genome. B) enable the human body to produce the SARS-coV-2 spike protein. C) inhibit viral polymerase. D) inhibit neuraminidase. E) inhibit reverse transcriptase.arrow_forwardWhy covid19 binds to Ace receptors only? Describe it's mechanism of infecting the cells?arrow_forwardHow were the structure of ACE2 and spike protein solved? describe the key processes involved in vaccine manufacturing. why is it easier to target a single mutant than a multiple mutants? why is SARS-CoV-2 so dangerous? summarise the key difference in the invasion of cell by: HIV, Adenovirus, Anthrax,SARS-CoV-2 and MERS What are the key players in the various mutants of spike proteins?arrow_forward
- Several vaccines against viral infections are made by isolating purified surface proteins of the viral particle, mixing them with an adjuvant to stimulate an innate immune response, and injecting the mixture into people. Two examples of this are the vaccine against Hepatitis B virus, and the vaccine against Human Papilloma Virus (the ‘cervical cancer’ vaccine). One interesting property of vaccines of this type (known as ‘subunit vaccines’) is that there is a requirement for a CD4 T cell response to the vaccine antigen in order to generate antibodies to the innocuous protein in the vaccine. In the case of the Hepatitis B vaccine, the viral protein included in the vaccine is the Hepatitis B surface antigen (HepB-SAg), a protein that is approximately 200 amino acids in length. The graph in Figure Q4.27 shows the data from immunizing individuals with this vaccine, and monitoring their production of protective antibody responses to the viral protein. a) What results would be predicted if…arrow_forward1)Describe the key processes involved in vaccine manufacturing.2) Review the literature and identify the key players in the various mutants of the spikeprotein.3) How were the structures of ACE 2 and spike protein solved?4) Why is it easier to target a single mutant versus multiple mutants in the virus?5) There are several coronaviruses in the database, why is the SARS-CoV-2 sodangerous?6) Summarize the key difference in the invasion of cells by:a.
