What is the primary function of the natural killer cell?
Producing early induced proteins
Promoting opsonization of bacteria cells
Secreting signaling molecules
Destroying virally infected cells
The Correct Answer is D
A. Producing early induced proteins: While natural killer cells can produce cytokines, their primary function is not related to protein production.
B. Promoting opsonization of bacteria cells: Opsonization is primarily performed by antibodies and complement proteins, rather than natural killer cells.
C. Secreting signaling molecules: While natural killer cells do secrete signaling molecules (cytokines) to communicate with other immune cells, their main role is the direct destruction of infected cells.
D. Destroying virally infected cells: The primary function of natural killer cells is to recognize and eliminate virally infected cells and tumor cells, contributing to the innate immune response.
