HY Concept 174

Here's one more at least:

A patient of yours is predisposed to TYPE I hypersensitivity. Which IL is mostly responsible. This is a great great question.... look below after guessing...

[tommyk]

Surprise, I bet you guessed IL-1 or TNF-a BUT NNOOOOO!

The answer is IL-4 IL-4 revs up IgE, WHICH THEN is responsible for anaphylactic shock.

THIS IS AN ULTIMATE CONCEPT. MANY STUDENTS JUST LINK IL-4 TO IgE, which is fine because some versions of the test will be that straightforward. BUT SOME OF THE TEST TAKERS WILL BE ASKED JUST LIKE I JUST DID, INDIRECTLY AND WITH A SECONDARY. It is not a HARD question, but you can GET EASILY DISTRACTED!

DO YOU GUYS AGREEE????? YOU HAVE TO PONDER AND REALLY THINK!
