Conclusion
These findings indicate that TRAIL-R4 is the predominant receptor in the interstitial cystitis inflammation.
Methods
TRAIL and its receptors were stained immunohistochemically in bladder biopsy samples of 27 patients diagnosed with interstitial cystitis, and the samples were evaluated independently by two pathologists and were scored in terms of expression intensity and distribution.
Results
An evaluation of the results of the statistical analysis showed that the TRAIL-R4 receptor was immunohistochemically stained with a higher score than TRAIL-R1, TRAIL-R2, TRAIL-R3 receptors and TRAIL, with a statistically significant difference (P < 0.05).
