Adaptive Immune Responses are Directed at Pathogen Molecules Called

Question

Adaptive immune responses are directed at pathogen molecules called
A) antigens.
B) antibodies.
C) T-cell receptors.
D) PAMP.

Accepted Answer

Adaptive immune responses are specifically targeted at foreign molecules, or antigens, that are found on pathogens. Antibodies and T-cell receptors are produced in response to these antigens. PAMP (pathogen-associated molecular patterns) are not specifically targeted by the adaptive immune system, but are instead recognized by innate immune receptors.
