background and aims: several studies have shown that there is greater number of viruses in deep periodontal pockets than in normal gingival sulcus. we also know that virus may have an important role in induction of il-1β secretion by different human cells. in this study we intended to determine the capacity of herpes simplex virus type 1 to stimulate il-1β secretion in human gingival keratinocy...
Calprotectin, a heterodimer of MRP8 and MRP14 with antimicrobial properties, is found in the cytosol of neutrophils, monocytes, and human gingival keratinocytes. During inflammation of the oral mucosa, the expression of immunoreactive calprotectin appears upregulated. Given the possible cell sources, we sought to learn if epithelial cells upregulate calprotectin in response to proinflammmatory ...
Infection is the primary failure modality for transcutaneous implants because the skin breach provides a route for pathogens to enter the body. Intraosseous transcutaneous amputation prostheses (ITAP) are being developed to overcome this problem by creating a seal at the skin-implant interface. Oral gingival epithelial cell attachment creates an infection-free seal around dental implants. Howev...
BACKGROUND AND OBJECTIVE Collagen type I elevation in cyclosporin A-induced gingival overgrowth supports evidence that gingival fibroblasts play a decisive role in the manifestation of the phenotype. To analyze the role of gingival fibroblasts under more in vivo-like conditions, we evaluated the effect of cyclosporin A on collagen type I gene and protein expression in gingival overgrowth-derive...
Objective(s)Tissue engineering is an attractive science because it promises new therapeutic strategies for repairing organs that have lost functions due to damage. The purpose of this study was to evaluate induction effect of human gingival scaffold in tissue engineering for skin regeneration.Materials and MethodsTissue samples were obtained from crown-lengthening procedures and wisdom teeth re...

AIM To evaluate fundamental cell functions, such as adhesion, IL-6 production and proliferation of human gingival keratinocytes cultured on a newly engineered collagen matrix (CM-10826) and to assess the degree of specific biocompatibility of this new device. MATERIALS AND METHODS Primary cultures of human keratinocytes were derived "in vitro" from biopsies of independent donors. Their true e...

Steroid sex hormones have a significant effect on different organ systems. As far as gingiva are concerned, they can influence the cellular proliferation, differentiation and growth of keratinocytes and fibroblasts. Estrogen is mainly responsible for alterations in blood vessels and progesterone stimulates the production of inflammatory mediators. In addition, some micro-organisms found in the ...
