Divergent activator mechanisms via MRGPRX2 pathway

This reasoning chain captures how different canonical mast cell activators (substance P, compound 48/80, 5-HT, PEA) have distinct effects in in vitro models, including nuances such as compound 48/80's dual role in both degranulation and toxicity, with supporting literature showing variable engagement of the MRGPRX2 receptor pathway and possible protective or modulatory agents. The chain explains the observed contradictions and limitations in using 48/80 as a universal mast cell activator.
