PAR2 activation in the colon by 2F sensitizes LSN responses to mechanical and chemical stimulation of the colon via endosomal internalization, PKA and PKC. LSN action potential firing after mechanical distention: gradually increasing intraluminal pressure from 0 to 80 mm Hg, and chemical application: 1 mM cinnamaldehyde and 1 µM capsaicin are illustrated in (A). (B) Responses to distention were quantified through the change in firing rate over increasing discrete pressure values. (C and D) Responses to chemical stimuli were quantified through the change in firing rate over time after application (vertical dotted line). 100 µM 2F stimulation, but not vehicle control, elicited sensitization of the LSN to (B) distention, (C) cinnamaldehyde, and (D) capsaicin. Pretreatment with PS2 before 2F stimulation reduced subsequent LSN responses to distention, cinnamaldehyde, and capsaicin compared with PN2. Pretreatment with H-89 and GFX, applied either simultaneously or individually, also reduced subsequent peak LSN responses to distention, cinnamaldehyde, and capsaicin compared with DMSO vehicle.

The possible mechanism of PAR2-β-arrestin 2-ERK signaling pathway on IL-17 release in keratinocytes On physiological state, PAR2, β-arrestin 2, and ZO-1 are in resting state, and ZO-1 is crucial for skin barrier maintenance. After overgrown M. globosa invades keratinocytes, the interaction of PAR2 with β-arrestin 2 and ZO-1 is enhanced and internalized, which upregulates ERK1/2 expression and ZO-1 disruption, thus promoting intracellular expression and extracellular release of IL-17.
