Question

Quizplus · Accepted Answer

Dermacidins are antimicrobial peptides that are part of the first line of defense against microbial invasion. TLRs and NOD proteins are part of the innate immune system and help to recognize pathogens, but they are not specific to the first line of defense. C3 and C5 are part of the complement system which is also involved in innate immunity but is not specific to the first line of defense. Interferons are produced by infected cells as a signaling molecule to alert neighboring cells but are not part of the first line of defense.
