  • Title: [New finding of the expression of human beta defensin-4 in healthy gingiva].
    Author: Li X, Duan D, Wang P, Han B, Xu Y.
    Journal: Hua Xi Kou Qiang Yi Xue Za Zhi; 2013 Apr; 31(2):165-8. PubMed ID: 23662559.
    Abstract:
    OBJECTIVE: To investigate the expression and the distribution of human beta defensin (hBD)-4 in healthy gingiva. METHODS: Healthy gingival specimens were collected. The expression of hBD-4 peptides in 18 gingival specimens were detected by immunohistochemistry. The hBD-4 mRNA were determined in freshly isolated gingival tissue by real time reverse transcription-polymerase chain reaction (real time RT-PCR) in 30 gingival specimens. RESULTS: In 18 gingival specimens, hBD-4 peptides were expressed in 13 gingival specimens. In 30 gingival specimens, hBD-4 were detected in 4 gingival specimens by real time RT-PCR. CONCLUSION: The distribution and the expression levels of hBD-4 are different in healthy gingiva. This result may suggest that the hBD-4 play a role in maintaining the periodontal health.
