A Fruit Fly,internally Infected by a Potentially Pathogenic Fungus,is Protected

Question

A fruit fly,internally infected by a potentially pathogenic fungus,is protected by
A)its plasma cells.
B)its immunoglobulins.
C)its antibodies.
D)its antimicrobial peptides.
E)its B cells.

Accepted Answer

Antimicrobial peptides are small molecules that can kill pathogens directly or indirectly by disrupting their membranes or interfering with their metabolism. Fruit flies are known to produce different types of antimicrobial peptides as part of their innate immune response to infections, including fungal infections. Therefore, it is likely that the fruit fly is protected by its own antimicrobial peptides against the potentially pathogenic fungus. Plasma cells, immunoglobulins, antibodies, and B cells are typically associated with the adaptive immune response, which is not present in insects like fruit flies.
