Findings show that PGD2 release depends on COX-1 in human mast cell models, suggesting important implications for asthma treatment.

This research aimed to characterize eicosanoid release from different human mast cell models.
Stimulated mast cells with anti-human IgE for 30 minutes
Measured β-hexosaminidase, cysteinyl leukotrienes, LTB4, and PGD2
Studied expression of COX-1 and COX-2 using western blot
Compared responses of LAD2, CBMC, and PBMC mast cell models
LAD2 released β-hexosaminidase and PGD2 in a dose-dependent manner upon stimulation
CBMC and PBMC showed significant increases in β-hexosaminidase, CysLTs, and LTB4
COX-1 inhibition abolished PGD2 release, confirming its role in biosynthesis
CBMC and PBMC responses included CysLTs and LTB4, indicating model differences

Choi et al. (2011) studied this question.
