In order to understand immune responses to COVID-19 viral infection, a researcher took five individuals of an animal model of the disease. One of these animals was infected, in controlled lab conditions, by nasal spray of the viral suspension. The animal developed pneumonia-like symptoms (fever and difficulty in breathing) ten days later. Blood plasma was collected at two time points from the infected animal: i. when
Options
- AIn treatment ( O ) , the viral antigen from the plasma generated a humoral immune response (antibody response)
- BIn treatment (M) fever was because of cytokines such as interferons that are in the plasma.
- CIn treatment ( O ) antibodies against COVID-19 gave passive immunity to the animal.
- DIn treatment (N) symptoms were mild, because interferons from the plasma set a general innate immune state in
Correct answer
D. In treatment (N) symptoms were mild, because interferons from the plasma set a general innate immune state in
