A client has been inhaling viruses periodically while on a cross-country flight. Which of the following situations listed below would most likely result in the stimulation of the client's T lymphocytes and adaptive immune system?
A)
Presentation of a foreign antigen by a familiar immunoglobulin
B)
Recognition of a foreign major histocompatibility complex (MHC) molecule
C)
Recognition of a foreign peptide bound to a self-major histocompatibility complex (MHC) molecule
D)
Cytokine stimulation of a T lymphocyte with macrophage or dendritic cell mediation
Ans:
C
Feedback:
The stimulation of T cells requires the recognition of a foreign peptide bound to a self-major histocompatibility complex (MHC) molecule. Immunoglobulins do not play an antigen-presenting role, and foreign MHC molecules and cytokines do not stimulate the adaptive immune system.
