SARS-CoV-2 is more contagious in humans than SARS because it has been shown that SARS-CoV-2 emerged from bats that were superspreaders. SARS-CoV-2 was derived from SARS by antigenic shift. There are more than 1 correct answers in the other choices if X number of SARS-CoV-2 particles would infect Y number of respiratory epithelial cells, higher (than X) number of SARS particles would be required to infect Y number of the same cells.

When an antibody binds to the spike protein of SARS-CoV-2, it may block access of the spike protein to the ACE2 protein on human cells. This is one way an antibody can prevent the virus from attaching to and getting inside of human cells. But antibodies can do more than just block virus entry. Due to the symmetrical structure of the immunoglobulin molecule, it can bind to two antigen molecules simultaneously, like this: As a result, antibodies can cross-link multiple viruses in a three-dimensional network. Using this diagram as a starting point, draw several additional viruses and antibodies to illustrate what a cross-linked antigen-antibody complex might look like.
H1N1 and H5N2 can undergo an antigenic shift. The H and N genes are independent gene segments. What variants of influenza could you get?
COVID-19 is caused by infection with a novel corona virus, SARS-CoV-2. Testing someone for active infection involves examining samples taken from the nasal mucosa for fragments of the virus. Another type of testing involves examining blood for the presence of antibodies that can bind to SARS-CoV-2. Use what you've learned about the immune system. What are the suggested reasons why someone would possess antibodies to SARS-CoV-2.
Shortly after the recovery from COVID 19, the plasma of the convalescent has significant quantities of anti - SARS CoV - 2 antibodies. This plasma was suggested to be used as therapy for other COVID - 19 patients by transfusing the plasma from the recovered individuals (donor) to the other COVID 19 patients (recipient). Do you think the identification of the ABO group of the donor and recipient is important and why?
“The SARS Coronavirus Type 2 (SARS-CoV-2) is known to cause respiratory tract infections and has been isolated from several bodily fluids. Although there is still no concrete evidence of an animal reservoir, the World Health Organization has prematurely classified the Coronavirus disease (COVID-19), caused by SARS-CoV-2, as a zoonotic disease”.2.1 In your own view, discuss the possible route of transmission of SARS-CoV-2 from an animalsource to humans
Organ Transplants Must Be Immunologically In the human HLA system there are 23 HLA-A alleles, 47 for HLA-B, 8 for HLA-C, 14 for HLA-DR, 3 for HLA-DQ, and 6 for HLA-DP. How many different human HLA genotypes are possible?
Vanad Patel arrived unconscious by ambulance at the emergency room following a motorcycle accident. He had severe injuries including a compound fracture of his tibia and needed immediate surgery and a blood transfusion. Routine blood-group typing categorized him as O+ because his red blood cells showed no reaction with anti-A or anti-B antibodies. But cross-matching with the different bags of O blood in the blood bank showed cross-reactivity or incompatibility with them all. The blood-bank staff reported that the patient had a rare blood type called the Bombay blood group. His twin brother Nadeesh, who arrived at the emergency room within hours of the family being notified, donated the blood his brother needed. It was recommended that he and his brother wear medical alert bracelets in case they need emergency blood transfusions in a situation where thorough cross-matching is not possible. Which of the following is consistent with the Bombay phenotype? a. The Bombay phenotype results…
When vesicular stomatitis virus (VSV) is used to infect mice via footpad injection, viral particles are trapped in the draining lymph node (the popliteal lymph node) within 5 minutes of injection. These viral particles are then retained in the lymph node for many hours, where they can be visualized on cells that are interacting with B cells. The cells retaining the viral particles in the lymph node are not tissue-resident dendritic cells that have migrated to the lymph node with the virus, as this process takes much longer than 5 minutes. In which region of the lymph node would you expect to find the trapped viral particles and on which cells?
A researcher performs an experiment where he infects 2 mice (Mouse A and Mouse B) with herpes simplex virus (HSV). To measure the cytotoxicity of CD8+ T cells from Mouse A, he isolates CD8+ T cells from Mouse A and co-cultures them with a mixture of HSV-infected spleen cells from Mouse B. 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 expression
In our current situation of being in a global pandemic due to SARS-COV-2, otherwise known as COVID-19, you have heard news and updates here in the philippines and abroad. As a dental student - clinician, what do you think is the implication of this situation in our daily lives? What actions do you make in order to prevent yourselves from being infected?
We now have at least three SARS-CoV-2/COVID-19 vaccines approved by the FDA for use in the United States. These vaccines cause cells in the body to make the spike protein that is on the surface of the virus, and subsequently, stimulate an antibody response to this antigen. A. What do these antibodies do to prevent infection by SARS-CoV-2? How do they interact with the virus particles? B. Which kind of cells in the immune system are responsible for synthesizing these antibodies?
In terms of antigens and antibodies, explain why O- is considered a universal donor and why AB+ is considered a universal recipient. Even so, why can’t whole blood O- be donated to a person of type AB+ blood?
