The results of the present study confirmed that PAR2 expression was significantly increased by stress. | |||||||||||||||
| |||||||||||||||
|
Acute stress in rats increases mast cell numbers and mucosal PAR2 expression in the colon. | |||||||||||||||
| |||||||||||||||
|
Stress-induced Alterations in Mast Cell Numbers and Proteinase-activated Receptor-2 Expression of the Colon: Role of Corticotrophin-releasing Factor
This study was performed in order to assess whether acute stress can increase mast cell and enterochromaffin (EC) cell numbers, and proteinase-activated receptor-2 (PAR2) expression in the rat colon. | |||||||||||||||
| |||||||||||||||
|
In conclusion, acute stress in rats increases mast cell numbers and mucosal PAR2 expression in the colon. | |||||||||||||||
| |||||||||||||||
|
Thus, it is plausible that CRF released during acute stress increases mast cell numbers and degranulates mast cells, which upregulates PAR2 expression in the colon. | |||||||||||||||

Stress-induced Alterations in Mast Cell Numbers and Proteinase-activated Receptor-2 Expression of the Colon: Role of Corticotrophin-releasing Factor
This study was performed in order to assess whether acute stress can increase mast cell and enterochromaffin (EC) cell numbers, and proteinase-activated receptor-2 (PAR2) expression in the rat colon. | |||||||||||||||
| |||||||||||||||
|
We speculate that a 90 min restraint session permits the release of CRF, which is able to increase mast cells and PAR2 expression in the colon. | |||||||||||||||
| |||||||||||||||
|
Our results of the present study showed that acute immobilization stress increased mast cell numbers and PAR2 expression in the colon and these stress effects were inhibited by the CRF antagonist astressin. | |||||||||||||||
| |||||||||||||||
|
Immunohistochemical analyses using the polyclonal antibody against rat PAR-2 clearly showed abundant expression of PAR-2 in rat pancreatic and parotid acini. | |||||||||||||||
| |||||||||||||||
|
CONCLUSIONS: These studies demonstrate that 1) CYP induced cystitis up-regulates PAR2 to 4 expression in the bladder, 2) PAR2 to 4 is expressed in urothelium, detrusor muscle and bladder nerve fibers in control and CYP treated rats, and 3) bladder C-fibers and bladder afferent cells in dorsal root ganglia express PAR2 to 4. | |||||||||||||||
| |||||||||||||||
|
Furthermore, inflammation resulted in the activation of the PAR2 receptors expressed on CANs.
| |||||||||||||||
| |||||||||||||||
|
Our data show that inflammation causes an up-regulation of the NMDA receptor and the activation of the PAR2 receptor expressed on CANs. | |||||||||||||||
| |||||||||||||||
|
The activation of PAR-2 provokes Ca++ mobilization and CGRP and substance P release in slices of rat isolated neurons or vascular intracranial structures cultured in vitro, while in vivo the swelling CGRP-induced of the rat paw is observed. | |||||||||||||||
