- Which of these is not part of insect immunity? (A) enzyme activation of pathogenkilling chemicals (B) activation of natural killer cells (C) phagocytosis by hemocytes (D) production of antimicrobial peptidesIf other animals have their immune system like man, what about the insects? In the context of circulation or the circulatory system, how do insects defend themselves from infection?Which of the following would not help a virus avoid triggeringan adaptive immune response?(A) having frequent mutations in genes for surface proteins(B) infecting cells that produce very few MHC molecules(C) producing proteins very similar to those of other viruses(D) infecting and killing helper T cells
- What term describes microbial molecules of pathogens such as peptidoglycan and LPS that can trigger the innate immune system to respond? O 1) PAMP O 2) epitope O 3) antigen O 4) haptenWhich part of the immune system does not target specific new variants of the COVID 19 invaders? A) antibodies B) specific defense C) antigens D) innate responseIn December 2020, Jean, a 30 year-old man, went to a concert in his town where more than 3 thousand people attended. Only 30% of the people in the concert were wearing mask, and there was not enough space to keep social distance. After 6 days, Jean started to develop fever and he lost the sense of smell and taste. Eight days after the party, he began to have difficulty breathing and was diagnosed with COVID-19. Let’s try to write the whole story about how the SARS-CoV2 invaded Jean’s body. The T cell response follows the antibody-mediated B cell immunity. What is the connection between B and T cells to build an effective immune response to SARS-Cov2?

SARS-CoV2 viral particles entered Jean’s nasal cavity and attached to the respiratory mucous membranes. Some mucosal barriers prevent part of the viral particles to penetrate the respiratory epithelium. Which are these barriers and how do they act? 2) Which cells are recruited from the bloodstream to the connective tissue (under the respiratory epithelium) to phagocyte the viral particles? Explain the recruitment mechanism.
