BACKGROUND
Trappin-2 is one of the potent biologically active serine protease inhibitor with anti-inflammatory properties that has also been characterized as an "alarm anti-protease". Despite the importance of Trappin-2 in several chronic infections has been demonstrated, its potential involvement
Microbial spectrum and non-specific as well as specific IgA1 protease activity of isolated microorganisms were investigated in gingival liquid of patients with periodontitis. Microorganisms from the gingival liqud of these patients belonged to conditional-pathogenic obligate and facultatively
Porphyromonas gingivalis is associated with the development of periodontitis. Here we describe the development of a highly specific protease-based diagnostic method for the detection of P. gingivalis in gingival crevicular fluid. Screening of a proteolytic peptide substrate library, including
OBJECTIVE
This study aimed to investigate the difference in salivary protease expression in patients with chronic periodontitis and normal individuals.
METHODS
The stimulating saliva in patients with chronic periodontitis and normal individuals were collected. Protein chip technology was adapted to
The purpose of this work was to study the elastase content of PMNs, the elastase alpha1-protease inhibitor complex, and the protease inhibitors in the plasma of patients with periodontal disease as compared with healthy subjects. We examined 11 patients with localized juvenile periodontitis (LJP),
OBJECTIVE
Protease activated receptor type 1 (PAR1 ) seems to play a role in periodontal repair, while PAR2 is associated with periodontal inflammation. As diabetes is a known risk factor for periodontal disease, the aim of this study was to evaluate the influence of type 2 diabetes on PAR1 and PAR2
OBJECTIVE
There are indications that acute myocardial infarction (AMI) may have an effect on the oral environment, which is reflected in the expression of salivary and gingival proteinases. According to our knowledge, no studies have been carried out to investigate the effect of AMI on the
The aim of this retrospective study was to determine if a chairside assay for neutral protease activity in gingival crevicular fluid (GCF) could provide an early indication of site-specific disease activity, as defined by probing attachment loss. Clinical measures and assay data were collected at
BACKGROUND
Periodontitis is characterized by extensive destruction of the gingival tissues and associated supporting structures of the teeth. Although the pathogenesis of the various forms of this disease is not completely understood, host-derived proteases are believed to have an important role. In
OBJECTIVE
The aim of this study was to evaluate the short-term effect of non-surgical periodontal treatment on protease activity in gingival crevicular fluid (GCF) of patients with chronic periodontitis.
METHODS
After clinical examination, in which pocket probing depth, probing attachment level,
UNASSIGNED
Protease-activated receptors (PAR-1 and PAR-2) are found to be immensely exhibited in the periodontal tissues. These receptors are involved in the inflammatory and repair processes. Activation of PARs is mainly by the bacterial and endogenous enzymes. The aim of the study was to determine
BACKGROUND
Periodontitis is a common infectious disease to which Porphyromonas gingivalis has been closely linked, in which the attachment tissues of the teeth and their alveolar bone housing are destroyed. We conducted a study to determine if immunization using a purified antigen could alter the
The tissue destruction seen in chronic periodontitis is commonly accepted to involve extensive upregulation of the host inflammatory response. Protease-activated receptor 2 (PAR-2)-null mice infected with Porphyromonas gingivalis did not display periodontal bone resorption in contrast to
OBJECTIVE
Elastase is carried into the oral cavity by gingival crevicular fluid (GCF) from periodontal lesions. Our study investigated the regulation of elastase activity by secretory leukocyte protease inhibitor (SLPI) and the possible action of another GCF protease on this protective salivary
OBJECTIVE
To investigate the expression types of protease-activated receptors(PAR) in human gingival fibroblasts(HGF) and the functions of PAR in periodontitis.
METHODS
Primary HGF were cultured.Reverse transcription PCR(RT-PCR) was used to detect the expression of PAR in HGF. Recombinant gingipain
