Homework Answers
Opsonization
pathogens have PAMP (pathogen Associated Molecular Pattern) on the membrane which is recognized by the opsonins proteins like Antibodies. Cell like neutrophils, macrophage and monocytes are not able to recognize and bind directly to the all PAMPs present on the surface of pathogens hence needs the assistance by other cells in order to destroy the pathogen. Antibodies bind to the PAMP by the Fab fragment which has antigen-binding sites by the process known as opsonization and makes them susceptible to phagocytosis. The Fc portion of antibodies remains free. Macrophages, monocytes, and neutrophils have the receptor for the Fc portion of antibodies and bind to the antibodies already bounded with the pathogen this causes the phagocytosis of the antibodies bound pathogen.

Question VII. While working on an adenovirus vaccine,
you perform complement fixation assays to determine
semiquantitatively the titers of anti-viral antibody in the serum
of subjects following vaccination. You are using the typical
version of CFT, in which you add a standard amount of viral antigen
and complement to serial dilutions of the subjects’ sera, in which
complement was heat-inactivated and then adding sRBC. Your results
for three subjects are shown below:
Based on these results, assess each subsequent statement...
