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.

In this time of COVID-19 pandemic, a communicable disease caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), health experts suggest an optimal intake of nutrients plays crucial roles in boosting the immune system. Concerning your knowledge on biomolecules, how do eating carbohydrates and lipids improve our physical health in combating COVID-19 and other communicable diseases?
If antibody responses are not elicited by a Covid-19 vaccine, are there other types of immune response that could provide protection from the SARS-Co-V2 virus following vaccination? Explain why or why not.
To what cell-surface receptor does the SARS-CoV-2 Spike protein bind? a. What type of genome does SARS-CoV-2 have? Please help explain in less than 5 sentences! Thank you
In 1994, the U.S. Public Health Service identified “10 Essential Public Health Services.” For each of the ten, briefly describe a specific activity that has been used in the response to COVID-19.
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…
SARS-CoV-2 binds, or attaches, to specific proteins on the surface of a cell. These proteins are called receptors. Scientists have determined that SARS-CoV-2 binds to the same type of receptors on human cells as a different coronavirus that caused an outbreak in 2002–2004 did. That outbreak caused fewer infections and deaths than the SARS-CoV-2 outbreak. Scientists discovered that SARS-CoV-2 is 10 to 20 times more likely to bind to these receptors than the other coronavirus was. Predict how this increased chance of binding has affected SARS-CoV-2’s ability to replicate.?
Poliovirus is highly cytopathic both in cultured cells and in animals. Inoculation of mice with poliovirus leads to a robust antibody and cellular response. Explain why mice infected with a poliovirus mutant that cannot cause cell death have poor antibody and cellular responses. What would be one strategy to restore robust antibody and cellular responses in mice infected with this mutant virus?
please help answer this question Explain how ACE2-like carboxypeptidase B38-CAP protects from SARS-CoV-2-induced lung injury in the paper by Yamaguchi et al.?
The small fragments of some complement proteins initiate a local inflammatory response. Recent studies using mouse models of pulmonary inflammation (a model for human asthma) have found that mice deficient in the C3a receptor have greatly reduced disease symptoms when challenged with inhaled preparations containing extracts of the fungal pathogen Aspergillus fumigatus. Specifically, the C3a receptor-deficient mice showed reduced influx of granulocytes and lymphocytes into the lung and reduced fluid in the lung after challenge. What is the explanation for these findings?
The surface proteins on the lipid envelope of the hepatitis B virus specifically bind to receptor proteins on the surface of human liver cells. This viral‑host protein interaction allows the hepatitis B virus to infect human liver cells. A hepatitis B virus strain has been genetically modified so that the lipid envelope contains gp120 in addition to the regular surface proteins. What will the hepatitis B virus be able to infect? Select all that apply. human T cells human liver cells HIV bacterial cells
Consider the factors that lead to emergency of new infectious disease, which ones do you think could have contributed to COVID-19 and why?
Serum from individuals with high levels of antibody to SARS-CoV2 has been used to treat patients with severe COVID-19. What is ONE way (there are several) that passive immunization with the antibody to the virus could help these patients? HINT: think about what opsonization with antibody could do for the innate immune response.
