Please identify the INCORRECT definition regarding innate immunity.
A) First line defenses-the barriers that separate and shield the interior of the body from the surrounding environment (skin and mucous membranes).
B) Sentinel cells-host cells that help the immune system detect signs of invasion by producing cytokines when their PRRs recognize an invading microbe.
C) Inflammatory response-coordinated innate response involved in containing a site of damage, localizing the response, eliminating the invader, and restoring tissue function.
D) Innate lymphoid cells-a group of lymphocytes that have increased specificity in their mechanism of antigen recognition (example: natural killer (NK) cells).
E) RIG-like receptors-a group of pattern recognition receptors within cells that recognize molecules associated with infecting viruses.

Quizplus · Accepted Answer

The definition of innate lymphoid cells as having increased specificity in their mechanism of antigen recognition is incorrect. Innate lymphoid cells, including natural killer (NK) cells, are considered to have a limited specificity in their mechanism of antigen recognition.
