Chapter 3, Problem 54RE
THOUGHT QUESTION Imagine we identify a gene that is directly responsible for the effects of vasopressin on male mammals, including humans-we will call it trust1-that leads to the production of a vasopressin receptor in the brain, which we will call TRUST1. There are different versions of trust1, all of which lead to different levels of the behavior associated with this neuropeptide on male behavior. Give some examples where it would be a good idea to know a particular male’s genotype-that is, which of the trust1 genes he has. Give an example of when you think science has gone too far and this information should not be known.

Can Nanotechnology Help to Control the Cytokine Storm?
One of the main features of COVID-19 is the triggering of a cytokine storm in the body, also known as cytokine release syndrome (CRS), which results from an excessive immune response and leads to the severe deterioration of patient health. This inflammatory storm is one of the major causes of the acute respiratory distress syndrome (ARDS) that is often associated with multiple-organ failure, representing the leading causes of death in critical patients. In particular, the role of interleukin (IL)-6 has been highlighted in patients requiring assisted ventilation. Ongoing clinical trials are testing drugs that…

- question: Summarize the following in concise and understandable language. Nanotechnology Tools to Inactivate SARS-CoV-2 in Patients The main target of SARS-CoV-2 is the respiratory tract (upper airways, lung), although other organs might also be infected (e.g., gut, kidney) and vasculature also appears to be a prime target. The expression of ACE2 probably determines uptake by different tissues. In addition to discussing immune-based approaches, because the lung is the most critically affected organ, we will center our discussion on the various options to inactivate the virus in the deep lung and to target the essential host cells for drug delivery. The virus reaches the alveoli and enters alveolar epithelial type II cells (AECII), due to the relatively high abundance of ACE2 and a permissive cellular milieu. These cells serve as a reservoir of the virus, which finally spreads throughout the lung, leading to the lung function impairment seen in severe cases.
