What structures aid in our ability to identify potential pathogens as foreign and not self?
A)complement
B)LPS
C)cytokines
D)toll-like receptors

Question

Quizplus · Accepted Answer

Toll-like receptors are a type of pattern recognition receptor that aids in identifying potential pathogens by recognizing specific molecular patterns associated with them. This helps distinguish foreign molecules from self-molecules. Complement is a group of proteins that can help destroy pathogens, but it does not aid in identification. LPS is a component of the outer membrane of Gram-negative bacteria, but it is not an aid in identification. Cytokines are signaling molecules that help coordinate immune responses but are not directly involved in identifying pathogens as foreign.
