- Abstract
- We investigated whether tryptase released from mast cells activated by prostate stromal cells (PSC) reacted with Trichomonas vaginalis (Tv) promoted the proliferation of PSC through protease- activated receptor 2 (PAR2). Conditioned medium of PSC was prepared by stimulating them with Tv (Trichomonad-conditioned medium (TCM)), and mast cell-conditioned medium were prepared by incubating them with TCM (mast cell-TCM (M-TCM)). Mast cells incubated with TCM migrated more efficiently and produced more beta-hexosaminidase and tryptase. M-TCM containing tryptase increased the proliferation of PSC, while inhibition of tryptase decreased proliferation. Expression of signalling molecules such as PAR2, p-ERK, COX-2, 15d-PGJ(2) and PPAR gamma, known to be involved in the tryptase-PAR2 pathway, increased in response to M-TCM, and blocking any of these signals decreased proliferation, indicating that tryptase-PAR2 signalling is involved in the proliferation of PSC. Inhibition of tryptase and PAR2 led to reduced expression of PAR2, p-ERK, COX-2, 15d-PGJ(2) and PPAR gamma, while inhibition of ERK or COX-2 reduced the expression of COX-2, 15d-PGJ(2) and PPAR gamma indicating that the tryptase-PAR2 pathway proceeds in the order p-ERK, COX-2, 15d-PGJ(2), and PPAR gamma. These results show that interaction between PSC stimulated with Tv and mast cells causes proliferation of PSC through the tryptase-PAR2 pathway.
