Thanks for a good answer. This question made me feel like I was taking T21 pills
Thank you- I was really thinking this question had 2 correct answers... of course my dumbass picked Mast cells.
where do i find this info??
@ajss pg 112 of first aid 2019, under type I hypersensitivity. Immediate --> mast cells releasing histamine and tryptase, late--> eosinophils and leukotrienes recruited via chemokines
Wow, i missed the fact that the question is asking for the RESULT of the reaction, NOT the cause of the reaction. Mast cells cause the initial reaction, eosinophils would be the result of the eosinophils. *facepalm
Pathophys (as far as I understand it)...Mast cell degranulates, thus the phospholipid bilayer et. Al are left behind and needs to be degraded. Who comes in? Our good friend eosinophils, as they contain Major Basic Protein (responsible from breakdown of expired mast cell).
Note, you can tie this in to the delayed Leukotriene effects of an allergic rxn, as the bilayer is also broken down by arach. Acid.

Who else still doesn't know what T21 pills are and feels left out?

Mast cells degranulate, producing histamine which attracts eosinophils. The early stage of an allergic reaction is mast cell mediated, but the late stage (including mucus production) is mediated by eosinophils.
