Prokaryotic and eukaryotic cells respond to heat stress and other environmental
abuses by synthesizing a small set of stress proteins and by inhibiting
post-transcription synthesis of normal proteins. The purpose of the present study was to
document the stress response produced by inflamed gingival tissue in vivo, and cytokine
inducted human periodontal ligament cells. Human PDL cells were exposed to TNF-¥á
(1ng/§¢), INF-¥ã(200 U/§¢), LPS(100ug/§¢), combination of cytokine, and SDS-PAGE
gels running and Western blotting analysis was done. In vivo studies, the healthy
gingival tissusse of a control group and inflamed gingival tissue of adult periodontitis
were studied by immunohistochemistry and histology.
The results were as follows
1. HSP 47 was distributed on basal layer in healthy gingiva, but stronger stained in
basal, suprabasal, and spinous layer of inflamed gingiva.
2. HSP 47 was rare on endothelial cells and mononuclear cells in healthy gingiva, but
stronger expressed in inflamed gingiva.
3. HSP 70 expression was rare on epihelium and inflammatory cells hi both healthy &
inflamed gingiva.
4. HSP 70 was actively expressed on endothelial cells and inflammatory cells of
capillary lumen in moderately & mild inflamend gingiva.
5. PDL cells showed low level of HSP 47 protein expression which was significantly
induced by cytokine stimulation (LSP only and combination).
6. Maximum HSP 70 protein induction was seen with stimulation by a combination of
the cytokine, Combination of TNF-¥á, INF-¥ã, LPS have been shown to synergistically
effects of HSP 70 expression.
On the above findings, HSP Is influenced by cytokine and chronic inflammation in
vivo, and may be involved in protection of tissue during periodontal inflammatiom.
