Students have asked these similar questions
To put an end to the COVID-19 pandemic, vaccines were developed against the virus and people eligible to receive these are encouraged to get vaccinated. How do these vaccines work? *
The vaccine will not cause the disease, but will help develop the body’s first line of defense.
The vaccine mimics the virus that causes the disease and triggers the creation of antibodies.
No answer
The presence of the virus in the vaccine will improve the innate immune response of the body.
The vaccine causes a mild infection that will trigger the production of antibodies against the virus.
Because of similarities between hypoxia associated with high altitude and COVID-19, some studies have suggested that people living at high altitude may be accustom to low blood oxygen levels and therefore less adversely effected by coronavirus infection.
Based on your knowledge of acclimation/adaptations to high-altitude, DISCUSS whether you think high altitude hypoxia might protected against coronavirus infection. Justify your answer. Your words may not be more than 100 words.

Mix epithelial cells with heat-killed virus, wait 24 hrs, wash away any virus particles outside the epithelial cells, then add epithelial cells to dendritic cells. Mix epithelial cells with viral peptides, wait 24 hrs, wash away any viral peptides not bound to the epithelial cells, then add epithelial cells to dendritic cells.

Explainarrow_forwardPlease match A-E to the right description as shown in the picture. Thank you!arrow_forwardAn antigen acts is a molecule that acts like a name tag, allowing the immune system to recognize the cell it is attached to. The name tag might say: "Hello I'm... a deadly virus," or “Hello I'm... a healthy human cell." It is very important that an antigen for a deadly virus and a healthy human cell are very different, so that the immune system does not make a mistake and attack healthy human body cells. Which of the following molecules do you think would make good antigens for recognizing a pathogen? Justify your answer. You may choose more than one. 1) a cell wall protein 2) a piece of DNA inside a cell 3) a protein that is part of a flagella 4) a uniquely shaped protein that is part of a virus 5) a protein that is only made by prokaryotic cells 6) a protein that is only made by eukaryotic cellsarrow_forward

- A number of vaccines against the SARS-CoV-2 virus (which causes COVID) are currently in use. Based on what you learned about the immune system and vaccines, this vaccine should provide immunity against this virus because: a Vaccines bind to the variable region of immunoglobulins, and prevent the antibody-antigen interactions required for the virus to be released from cells. b Vaccines elicit a primary immune response and resulting memory cells specific to the viral antigens can persist in the body c Vaccines block clonal expansion of helper T cells which are required for the virus to infect cells d Vaccines block the production of cytokines e Vaccines induce cytotoxic T cells to produce antibodies specific to antigens on the virusarrow_forwardYou are studying SARS-COV2. You identify a viral protein that results in the decrease of MHC class I, a cell surface receptor, on the cell surface. You are trying to determine the mechanism for how the virus is decreasing cell surface MHC I. You decide to do an experiment to determine whether the receptor is making it all of the way through the secretory pathway. You take two samples of cells. 1. Uninfected 2. Infected with SARS-CoV2 You treat them with EndoH and analyze MHC I on a western blot and get the following results: 1. Uninfected cells - 50% of protein is endo H sensitive and 50% is Endo H resistant 2. SARS-COV2 infected cells - 100% of protein is Endo H sensitive How would you best interpret these results? Is MHC I going all the way through the secretory pathway in infected cells? A. No, MHC I is not going all the way through the secretory pathway. 100% of the protein is EndoH sensitive in infected cells, this means that the virus is somehow inhibiting the protein from making…arrow_forwardToll-like receptors represent an ancient pathogen-recognition system.
