Abstract
OBJECTIVE To explore the bacterial and inflammatory variations in oral cancer patients with and without jawbone invasion. MATERIALS AND METHODS A total of 20 specimens of fresh tumor tissue, including 10 from the tumor-invaded jawbone (JIOC group) and 10 without jawbone invasion (NJIOC group), were collected from oral cancer patients. Meanwhile, 10 specimens from normal oral mucosa were collected from healthy patients (control group). The microbiomic content of each sample was analyzed by 16S rRNA gene sequencing, while the expression of inflammatory cytokines was assessed using protein microarray analysis. RESULTS There was a significant difference in β diversity between JIOC and NJIOC groups (P < 0.05), but no difference between NJIOC and control groups. The average relative abundance of Fusobacteria and Spirochaetes was higher, while Firmicutes was lower in the JIOC group than in the NJIOC group (all P < 0.05). The expression of pro-inflammatory cytokines like interleukin (IL)-1α, IL-1β, IL-4, and IL-8 was upregulated in the JIOC group compared with the NJIOC group, while MCP-1 was decreased (all P < 0.05). Slackia spp. and Howardella spp. were positively correlated with IL-4; Odoribacter spp. and Acidaminococcaceae spp. were negatively correlated with IL-4, and Clostridium XIVa spp. was negatively correlated with IL-1α and IL-1β. CONCLUSION Bacterial and inflammatory differences were observed in oral cancer patients with and without jawbone invasion, where the relative abundance of the differential bacteria was associated with the expression of the inflammatory cytokines. CLINICAL RELEVANCE This study investigated the changes in the flora during jawbone invasion in oral cancer and its effect on inflammatory factors, elucidating the possible mechanisms of jawbone invasion caused by oral cancer, which may lead to new ideas for the clinical prevention and treatment of jawbone invasion in oral cancer.

Abstract
BACKGROUND The resolution of inflammation is an active process mediated by specialized lipid mediators called lipoxins and resolvins. Periodontal ligament fibroblasts (PDLFs) play a significant role in periodontal regeneration. The purpose of the current study was to determine the impact of resolvin D1 (RvD1) on human PDLF cell wound healing and proliferation, receptor expression (G-protein-coupled receptor 32 [GPR32] and formyl peptide receptor 2 [ALX/FPR2]), and cytokine expression and release. METHODS PDLFs were stimulated with interleukin-1β (IL-1β) (500 pg/ml) with and without RvD1 (100 nM). RvD1 receptor expression was determined by quantitative real-time polymerase chain reaction (qPCR), immunofluorescence microscopy, and fluorescence-activated cell sorting. Wound closure was measured by a scratch assay, and proliferation was determined by bromodeoxyuridine incorporation. Interleukin-6 (IL-6), interleukin-8 (IL-8), monocyte chemoattractant protein-1, cyclooxygenase-2, matrix metalloproteinases-1, -2, and -3 (MMP-1, -2, and -3), tissue inhibitors of metalloproteinases-1 and -2 (TIMP-1 and -2), prostaglandin E2, and osteoprotegerin (OPG) gene expression and production were measured using qPCR and Western blotting, multiplex immunoassay, and enzyme-linked immunosorbent assay. RESULTS PDLF expressed GPR32 and ALX/FPR2. RvD1 reversed IL-1β-induced inhibition of wound healing and proliferation of PDLF. IL-1β also induced the production of proinflammatory cytokines and MMPs. This effect was reversed by RvD1. RvD1 reversed IL-1β-induced inhibition of TIMP-1, TIMP-2, and OPG. CONCLUSION The data suggested that RvD1 has a pro-wound healing, proliferative, and anti-inflammatory impact on the PDLF that favors periodontal regeneration.

Abstract
Squamous cell carcinoma is the most common malignant tumor of the oral cavity and its adjacent sites, which endangers the physical and mental health of patients and has a complex etiology. Chronic infection is considered to be a risk factor in cancer development. Evidence suggests that periodontal pathogens, such as Porphyromonas gingivalis, Fusobacterium nucleatum, and Treponema denticola, are associated with oral squamous cell carcinoma (OSCC). They can stimulate tumorigenesis by promoting epithelial cells proliferation while inhibiting apoptosis and regulating the inflammatory microenvironment. Candida albicans promotes OSCC progression and metastasis through multiple mechanisms. Moreover, oral human papillomavirus (HPV) can induce oropharyngeal squamous cell carcinoma (OPSCC). There is evidence that HPV16 can integrate with host cells' DNA and activate oncogenes. Additionally, oral dysbiosis and synergistic effects in the oral microbial communities can promote cancer development. In this review, we will discuss the biological characteristics of oral microbiome associated with OSCC and OPSCC and then highlight the mechanisms by which oral microbiome is involved in oral oncogenesis, tumor progression, and metastasis. These findings may have positive implications for early diagnosis and treatment of oral cancer.

HDAC5-Mediated Acetylation of p100 Suppresses Its Processing. Int Dent J 2022; 73:387-394.

Abstract
INTRODUCTION Periodontitis is a condition involving chronic inflammation in the gums, periodontal ligaments, cementum, and alveolar bone. Nuclear factor-κB (NF-κB) activation is the prominent mediator of inflammation and osteoclast differentiation. The role of histone deacetylase 5 (HDAC5) in periodontitis development and NF-κB regulation is not fully understood. METHODS We used primary mouse bone marrow-derived osteoclast cultures in vitro and a mouse model of chronic periodontists (CPD) treated with the HDAC4/5 inhibitor LMK-235. Real-time polymerase chain reaction, micro computed tomography, flow cytometry, western blot, and immunoprecipitation were used to study proinflammatory cytokines, NF-κB activation, HDAC5 activity, and the interaction of HDAC5 with NF-κB p100. RESULTS LMK-235, a selective inhibitor of HDAC4 and HDAC5, reduced osteoclast marker gene expression (Cstk, Acp5, and Calcr) and tartrate-resistant acid phosphatase activity in primary osteoclast cultures. LMK-235 reduced the increase in cementoenamel junction-alveolar bone crest distance, inflammatory cell infiltration of gingival tissues, and expression levels of interleukin (IL)-1β, tumor necrosis factor alpha, IL-6, and IL-23a, indicating an ameliorative effect on CPD. Immunoprecipitation experiments have further confirmed p100-HDAC5 interaction, acetylation levels of p100, and NF-κB activation. CONCLUSIONS These results indicate that HDAC5 binds and deacetylates p100, leading to its activation, increased proinflammatory cytokine production, gingival infiltration, and osteoclast differentiation, thus promoting alveolar bone resorption. HDAC5 inhibition is therefore a potentially promising therapeutic strategy for the treatment of periodontitis.

Abstract
Junction epithelium (JE) is located apical to the bottom of the gingival sulcus and binds enamel to hemidesmosomes to protect the periodontal tissue from bacterial infection. Function of odontogenic ameloblast-associated protein (ODAM) is suggested by its expression sites (JE and maturation stage ameloblasts) to be involved in the adhesion between the JE and enamel, and odontogenesis. To analyze the changes in ODAM gene and protein expressions in inflamed gingiva, Ca9-22 gingival epithelial cells were stimulated with 1 ng/ml interleukin-1β (IL-1β) for 3-24 h, and ODAM mRNA and protein levels were analyzed by real-time PCR and Western blotting. Luciferase (LUC) constructs were made ligating various lengths of human ODAM gene promoters and performed LUC analyses in Ca9-22 cells. Gel shift and chromatin immunoprecipitation (ChIP) assays were performed. IL-1β induced ODAM mRNA and protein levels at 6-24 h. IL-1β increased LUC activities of the ODAM gene promoter constructs from - 85 to - 950. These activities were blocked by protein kinase A, tyrosine kinase, mitogen-activated protein (MAP) kinase kinase and phosphoinositide 3-kinase inhibitors. Gel shift and ChIP assays showed that IL-1β induced CCAAT/enhancer-binding protein (C/EBP) β and Yin Yang1 (YY1) binding to C/EBP1, 2, 3, and YY1 elements. These data indicate that IL-1β stimulates ODAM gene transcription mediated through C/EBP1, C/EBP2, C/EBP3, and YY1 elements in the human ODAM gene promoter.

Abstract
Periodontitis is an inflammatory disease induced by a dysbiotic oral microbiome. Probiotics of the genus Bifidobacterium may restore the symbiotic microbiome and modulate the immune response, leading to periodontitis control. We evaluated the effect of two strains of Bifidobacterium able to inhibit Porphyromonas gingivalis interaction with host cells and biofilm formation, but with distinct immunomodulatory properties, in a mice periodontitis model. Experimental periodontitis (P+) was induced in C57Bl/6 mice by a microbial consortium of human oral organisms. B. bifidum 1622A [B+ (1622)] and B. breve 1101A [B+ (1101)] were orally inoculated for 45 days. Alveolar bone loss and inflammatory response in gingival tissues were determined. The microbial consortium induced alveolar bone loss in positive control (P + B-), as demonstrated by microtomography analysis, although P. gingivalis was undetected in oral biofilms at the end of the experimental period. TNF-α and IL-10 serum levels, and Treg and Th17 populations in gingiva of SHAM and P + B- groups did not differ. B. bifidum 1622A, but not B. breve 1101A, controlled bone destruction in P+ mice. B. breve 1101A upregulated transcription of Il-1β, Tnf-α, Tlr2, Tlr4, and Nlrp3 in P-B+(1101), which was attenuated by the microbial consortium [P + B+(1101)]. All treatments downregulated transcription of Il-17, although treatment with B. breve 1101A did not yield such low levels of transcripts as seen for the other groups. B. breve 1101A increased Th17 population in gingival tissues [P-B+ (1101) and P + B+ (1101)] compared to SHAM and P + B-. Administration of both bifidobacteria resulted in serum IL-10 decreased levels. Our data indicated that the beneficial effect of Bifidobacterium is not a common trait of this genus, since B. breve 1101A induced an inflammatory profile in gingival tissues and did not prevent alveolar bone loss. However, the properties of B. bifidum 1622A suggest its potential to control periodontitis.

Abstract
Bacteria identified in the oral cavity are highly complicated. They include approximately 1000 species with a diverse variety of commensal microbes that play crucial roles in the health status of individuals. Epidemiological studies related to molecular pathology have revealed that there is a close relationship between oral microbiota and tumor occurrence. Oral microbiota has attracted considerable attention for its role in in‐situ or distant tumor progression. Anaerobic oral bacteria with potential pathogenic abilities, especially Fusobacterium nucleatum and Porphyromonas gingivalis, are well studied and have close relationships with various types of carcinomas. Some aerobic bacteria such as Parvimonas are also linked to tumorigenesis. Moreover, human papillomavirus, oral fungi, and parasites are closely associated with oropharyngeal carcinoma. Microbial dysbiosis, colonization, and translocation of oral microbiota are necessary for implementation of carcinogenic functions. Various underlying mechanisms of oral microbiota‐induced carcinogenesis have been reported including excessive inflammatory reaction, immunosuppression of host, promotion of malignant transformation, antiapoptotic activity, and secretion of carcinogens. In this review, we have systemically described the impact of oral microbial abnormalities on carcinogenesis and the future directions in this field for bringing in new ideas for effective prevention of tumors.

= 0.001); respective values for the control group were 10.63 ± 11.50, and 9.33 ± 11.73 and the difference was nonsignificant (
p
= 0.076).
Conclusion
This randomized trial indicated that sodium bicarbonate mouth rinse is effective in decreasing IL-1β levels and increasing salivary pH favorable for prevention of oral diseases.

Abstract
Oral squamous cell carcinoma (OSCC) is the leading cause of mortality for oral cancer. Numerous risk factors mainly related to unhealthy habits and responsible for chronic inflammation and infections have been recognized as predisposing factors for oral carcinogenesis. Recently, even microbiota alterations have been associated with the development of human cancers. In particular, some specific bacterial strains have been recognized and strongly associated with oral cancer development (Capnocytophaga gingivalis, Fusobacterium spp., Streptococcus spp., Peptostreptococcus spp., Porphyromonas gingivalis and Prevotella spp.). Several hypotheses have been proposed to explain how the oral microbiota could be involved in cancer pathogenesis by mainly paying attention to chronic inflammation, microbial synthesis of cancerogenic substances, and alteration of epithelial barrier integrity. Based on knowledge of the carcinogenic effects of dysbiosis, it was recently suggested that probiotics may have anti-tumoral activity. Nevertheless, few data exist with regard to probiotic effects on oral cancer. On this basis, the association between the development of oral cancer and oral dysbiosis is discussed focusing attention on the potential benefits of probiotics administration in cancer prevention.

Abstract
Interleukin-1β (IL-1β), which is secreted by host tissues leading to periodontal tissue inflammation, is a major pro-inflammatory cytokine in the pathogenesis of periodontal disease. The conversion of pro-IL-1β into its biologically active form is controlled by multiprotein complexes named as inflammasomes, which are key regulator of host defense mechanisms and inflammasome involved diseases, including the periodontal diseases. Inflammasomes are regulated by different proteins and processes, including pyrin domain (PYD)-only proteins (POPs), CARD-only proteins (COPs), tripartite motif family proteins (TRIMs), autophagy, and interferons. A review of in vitro, in vivo, and clinical data from these publications revealed that several inflammasomes including (NOD)-like receptor (NLR) pyrin domain-containing 3 (NLRP3) and absent in melanoma 2 (AIM2) have been found to be involved in periodontal disease pathogenesis. To the best of our knowledge, the current article provides the first review of the literature focusing on studies that evaluated both inflammasomes and their regulators in periodontal disease. An upregulation for inflammasomes and a downregulation of inflammasome regulator proteins including POPs, COPs, and TRIMs have been reported in periodontal disease. Although interferons (types I and II) and autophagy have been found to be involved in periodontal disease, their possible role in inflammasome activation has not evaluated yet. Modulating the excessive inflammatory response by the use of inflammasome regulators may have potential in the management of periodontal disease.

Abstract
Pancreatic cancer is one of the most lethal diseases. In pancreatic cancer development and progression, genetic (gene mutations and activation of oncogenes) and environmental factors (smoking, alcohol consumption, type 2 diabetes mellitus, obesity) play an essential role. Recently, molecular studies revealed that dysbiosis of microbiota also has influence on cancer development. Research indicates that bacteria and viruses can lead to chronic inflammation, antiapoptotic changes, cell survival, and cell invasion. This review presents bacteria and viruses oncogenic for the pancreas. Possible mechanisms of carcinogenic action are also described.

Abstract
Nowadays cancer is the second main cause of death in the world. The most known bacterial carcinogen is Helicobacter pylori. Pathogens that can have an impact on cancer development in the gastrointestinal tract are also found in the oral cavity. Some specific species have been identified that correlate strongly with oral cancer, such as Streptococcus sp., Peptostreptococcus sp., Prevotella sp., Fusobacterium sp., Porphyromonas gingivalis, and Capnocytophaga gingivalis. Many works have also shown that the oral periopathogens Fusobacterium nucleatum and Porphyromonas gingivalis play an important role in the development of colorectal and pancreatic cancer. Three mechanisms of action have been suggested in regard to the role of oral microbiota in the pathogenesis of cancer. The first is bacterial stimulation of chronic inflammation. Inflammatory mediators produced in this process cause or facilitate cell proliferation, mutagenesis, oncogene activation, and angiogenesis. The second mechanism attributed to bacteria that may influence the pathogenesis of cancers by affecting cell proliferation is the activation of NF-κB and inhibition of cellular apoptosis. In the third mechanism, bacteria produce some substances that act in a carcinogenic manner. This review presents potentially oncogenic oral bacteria and possible mechanisms of their action on the carcinogenesis of human cells.

Abstract
One of the major causes of tooth loss is chronic inflammation of the periodontium, the tissues surrounding the tooth. Amelotin (AMTN) is a tooth enamel protein which is expressed in maturation‐stage ameloblasts and also in the internal basal lamina of junctional epithelium, a unique epithelial structure attached to the tooth surface which protects against the constant microbiological challenge to the periodontium. Localization of AMTN suggests that its function could be involved in the dentogingival attachment. The purpose of this study was to investigate the effect of interleukin‐1β (IL‐1β) on AMTN gene transcription in human gingival epithelial Ca9‐22 cells. IL‐1β increased AMTN mRNA and protein levels at 3 h, and the levels reached maximum at 6 and 12 h. IL‐1β induced luciferase activities of human AMTN gene promoter constructs (−211, −353, −501, −769, and −950AMTN), but these activities were partially inhibited in −353AMTN constructs that included 3‐bp mutations in CCAAT/enhancer binding protein 1 (C/EBP1), C/EBP2, and Ying Yang 1 (YY1) elements. Transcriptional activities induced by IL‐1β were abrogated by protein kinase A (PKA), tyrosine kinase, mitogen‐activated protein kinase kinase (MEK1/2), and phosphatidylinositol 3‐kinase (PI3K) inhibitors. Gel shift and ChIP assays showed that IL‐1β increased C/EBPβ binding to C/EBP1 and C/EBP2, and YY1 binding to YY1 elements after 3 h, and that these DNA–protein interactions were inhibited by PKA, tyrosine kinase, MEK1/2, and PI3K inhibitors. These results demonstrated that IL‐1β increases AMTN gene transcription in human gingival epithelial cells mediated through C/EBP1, C/EBP2, and YY1 elements in the human AMTN gene promoter.

Abstract
Carriage of polymorphic alleles of genes of cytokines-interleukines IL-1β, IL-1RN, TNFα, IL-4 can be a specific feature of chronic periodontitis patients. Genetic tests can be used to predict the course of the disease at its early manifestations. Objective: To establish the relationship of clinical manifestations of periodontal disease, inflammatory cytokines gene polymorphism and systemic levels of cytokine production. Periodontal tissue assessment and cone-beam computed tomography (CBCT) were performed in 150 periodontitis patients. A molecular--genetic testing for the presence of polymorphic alleles of genes IL-1β -511 C>T and +3953 C>T, IL-1RN (VNTR intron 2), IL-4 (VNTR intron 3), TNFα-308 G>A; content determined IL-1β, TNFα, IL-4 in peripheral blood was carried out in 150 patients with periodontitis and 150 healthy donors. Based on the analysis of the speed and nature of the supporting bone resorption and clinical manifestations patients are divided in "aggressive", "moderately progressive" and "slowly progressive" periodontits course groups. Disease severity was associated with distribution of genotypes and alleles of polymorphic genes cytokine IL-1RN (VNTR intron 2), TNFα-308 G>A and IL-4 (VNTR intron 3); haplotype IL-1β-511 TIL-1β +3953 T/IL-1RN 2R. There was no statistically significant difference in systemic level of IL-1β, TNFα and IL-4 between periodontitis groups but the donor level of cytokines was 2-4 times less.

Abstract
Background and Objective: Smoking is an important environmental risk factor involved in the causation and progression of periodontal disease. Smoking can impair various components of the host immune response and immune system. The virulence factors of periodontal pathogens stimulate inflammatory cytokine expression by mononuclear cells. IL-1β is the key mediator involved in the pathogenesis and disease progression. Therefore, whole gingival biopsy samples are assessed for this increased expression of IL-1. Materials and Methods: 29 male subjects’ age and gender matched were divided into three groups based on the periodontal and smoking status (Group A:healthy, Group B: non-smokers suffering from chronic periodontitis, Group C: smokers suffering from chronic periodontitis). Periodontal parameters like plaque index, gingival index, probing pocket depth and clinical attachment level were recorded at baseline and post scaling. The mRNA expression of IL-1β was determined by real time polymerase chain reaction and correlated with the periodontal and smoking status. Results: The improvement in the periodontal parameters was statistically significant in the non- smokers (Group B) and there was a 2 fold increase in the mRNA expression in this group. The smokers (Group C) showed lesser improvement in the periodontal parameters and there was an 8 fold increase in the mRNA expression of IL-1β. Conclusion: Association of smoking status with periodontal destruction can thus be correlated with the increased mRNA expression of IL-1β in chronic periodontitis patients.

Abstract
Osteoimmunology represents a large area of research resulting from the cross talk between bone and immune systems. Many cytokines and signaling cascades are involved in the field of osteoimmunology, originating from various cell types. The RANK/receptor activator of nuclear factor Kappa-B ligand (RANKL)/osteoprotegerin (OPG) signaling has a pivotal role in osteoimmunology, in addition to proinflammatory cytokines such as tumor necrosis factor-α, interleukin (IL)-1, IL-6, and IL-17. Clinically, osteoimmunological disorders, such as rheumatoid arthritis, osteoporosis, and periodontitis, should be classified according to their pattern of osteoimmunological serum biomarkers. Paget’s disease of bone is a common metabolic bone disorder, resulting from an excessively increased bone resorption coupled with aberrant bone formation. With the exception of the cellular responses to measles virus nucleocapsid protein and the interferon-gamma signature, the exact role of the immune system in Paget’s disease of bone is not well understood. The cytokine profiles, such as the increased levels of IL-6 and the interferon-gamma signature observed in this disease, are also very similar to those observed in other osteoimmunological disorders. As a potential osteoimmunological disorder, the treatment of Paget’s disease of bone may also benefit from progress made in targeted therapies, in particular for receptor activator of nuclear factor Kappa-B ligand and IL-6 signaling inhibition.

Increased Eotaxin and MCP-1 Levels in Serum from Individuals with Periodontitis and in Human Gingival Fibroblasts Exposed to Pro-Inflammatory Cytokines. PLoS One 2015; 10:e0134608. [PMID: 26241961 PMCID: PMC4524692 DOI: 10.1371/journal.pone.0134608] [Citation(s) in RCA: 46] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2015] [Accepted: 07/11/2015] [Indexed: 11/19/2022] Open
Abstract
Periodontitis is a chronic inflammatory disease of tooth supporting tissues resulting in periodontal tissue destruction, which may ultimately lead to tooth loss. The disease is characterized by continuous leukocyte infiltration, likely mediated by local chemokine production but the pathogenic mechanisms are not fully elucidated. There are no reliable serologic biomarkers for the diagnosis of periodontitis, which is today based solely on the degree of local tissue destruction, and there is no available biological treatment tool. Prompted by the increasing interest in periodontitis and systemic inflammatory mediators we mapped serum cytokine and chemokine levels from periodontitis subjects and healthy controls. We used multivariate partial least squares (PLS) modeling and identified monocyte chemoattractant protein-1 (MCP-1) and eotaxin as clearly associated with periodontitis along with C-reactive protein (CRP), years of smoking and age, whereas the number of remaining teeth was associated with being healthy. Moreover, body mass index correlated significantly with serum MCP-1 and CRP, but not with eotaxin. We detected higher MCP-1 protein levels in inflamed gingival connective tissue compared to healthy but the eotaxin levels were undetectable. Primary human gingival fibroblasts displayed strongly increased expression of MCP-1 and eotaxin mRNA and protein when challenged with tumor necrosis factor-α (TNF-α and interleukin-1β (IL-1β), key mediators of periodontal inflammation. We also demonstrated that the upregulated chemokine expression was dependent on the NF-κΒ pathway. In summary, we identify higher levels of CRP, eotaxin and MCP-1 in serum of periodontitis patients. This, together with our finding that both CRP and MCP-1 correlates with BMI points towards an increased systemic inflammatory load in patients with periodontitis and high BMI. Targeting eotaxin and MCP-1 in periodontitis may result in reduced leukocyte infiltration and inflammation in periodontitis and maybe prevent tooth loss.

CD36/SR-B2-TLR2 Dependent Pathways Enhance Porphyromonas gingivalis Mediated Atherosclerosis in the Ldlr KO Mouse Model. PLoS One 2015; 10:e0125126.

Abstract
There is strong epidemiological association between periodontal disease and cardiovascular disease but underlying mechanisms remain ill-defined. Because the human periodontal disease pathogen, Porphyromonas gingivalis (Pg), interacts with innate immune receptors Toll-like Receptor (TLR) 2 and CD36/scavenger receptor-B2 (SR-B2), we studied how CD36/SR-B2 and TLR pathways promote Pg-mediated atherosclerosis. Western diet fed low density lipoprotein receptor knockout (Ldlr°) mice infected orally with Pg had a significant increase in lesion burden compared with uninfected controls. This increase was entirely CD36/SR-B2-dependent, as there was no significant change in lesion burden between infected and uninfected Ldlr° mice. Western diet feeding promoted enhanced CD36/SR-B2-dependent IL1β generation and foam cell formation as a result of Pg lipopolysaccharide (PgLPS) exposure. CD36/SR-B2 and TLR2 were necessary for inflammasome activation and optimal IL1ß generation, but also resulted in LPS induced lethality (pyroptosis). Modified forms of LDL inhibited Pg-mediated IL1ß generation in a CD36/SR-B2-dependent manner and prevented pyroptosis, but promoted foam cell formation. Our data show that Pg infection in the oral cavity can lead to significant TLR2-CD36/SR-B2 dependent IL1ß release. In the vessel wall, macrophages encountering systemic release of IL1ß, PgLPS and modified LDL have increased lipid uptake, foam cell formation, and release of IL1ß, but because pyroptosis is inhibited, this enables macrophage survival and promotes increased plaque development. These studies may explain increased lesion burden as a result of periodontal disease, and suggest strategies for development of therapeutics.

Abstract
BACKGROUND The synergistic effects of vitamin D3 and vitamin K2 on bone loss prevention have been reported. This study evaluates the effects of vitamin D3 and vitamin K2 supplementation in conjunction with conventional periodontal therapy (scaling and root planing [SRP]) on gingival interleukin (IL)-1β and IL-10, serum bone alkaline phosphatase (B-ALP) and tartrate-resistant acid phosphatase 5b (TRAP-5b), and calcium and alveolar bone levels in rats with experimentally induced periodontitis. METHODS Seventy-two rats were divided into the following groups: 1) healthy; 2) periodontitis; 3) SRP; 4) SRP + vitamin D3; 5) SRP + vitamin K2; and 6) SRP + vitamins K2 and D3. Periodontitis was induced by ligature placement for 7 days, and vitamin K2 (30 mg/kg) and/or vitamin D3 (2 μg/kg) were administered for 10 days in the SRP + vitamin D3, SRP + vitamin K2, and SRP + vitamins K2 and D3 groups by oral gavage. On day 18, the animals were sacrificed, serum B-ALP, TRAP-5b, and calcium levels were measured, gingiva specimens were extracted for IL-1β and IL-10 analysis, and distances between the cemento-enamel junction and alveolar bone crest were evaluated. RESULTS Alveolar bone levels in the periodontitis group were significantly greater than those in the other five groups. No significant differences were found in gingival IL-1β and IL-10, serum B-ALP and TRAP-5b, and calcium and alveolar bone levels between the groups receiving SRP and vitamins and the group receiving SRP alone. CONCLUSION Within the limitations of this study, vitamin D3 and K2 alone or in combination did not affect gingival IL-1β and IL-10, serum B-ALP and TRAP-5b levels, or alveolar bone compared with conventional periodontal therapy alone.

Abstract
BACKGROUND The purpose of this study is to determine whether sex dimorphism exists in the expression of inflammatory and apoptotic mediators in gingiva obtained from normal and diseased sites of periodontal disease. METHODS Gingival papillae were obtained from individuals (56 males and 62 females) who required extraction of adjacent teeth. Gingival samples were grouped by adjacent sulcus depth: 1 to 3 mm (normal), 3 mm with bleeding on probing (slight disease), 3 to 6 mm (moderate disease), and >6 mm (severe disease). The tissue concentrations of cysteine-requiring aspartate-directed protease 3 (caspase-3), interleukin-2, tumor necrosis factor-related apoptosis-inducing ligand, Fas ligand, p38α mitogen-activated protein kinase, extracellular signal-related kinase 1/2, and survivin were determined by enzyme-linked immunosorbent assay. These mediator concentrations, age of donor, sex of donor, and gingival sulcular depth were the outcome variables. Data were compared by factorial analysis of variance, post hoc Tukey, and Pearson correlation test. P <0.05 was used to indicate significant differences among the outcome variables. RESULTS The mean gingival sulcular depth was significantly greater in male than in female groups (P <0.05). The majority of the tested mediators were significantly correlated with both sex and sulcular depth and with caspase-3 (P <0.05). The concentration of caspase-3 in female gingiva at all diseased sites was significantly greater than in gingiva derived from male sites (P <0.05). CONCLUSIONS These data suggest sex dimorphism in the presence of gingival apoptosis at sites of periodontal disease, with females having the highest incidence of apoptosis. Because apoptosis clears inflammatory cells and promotes healing, this phenomenon could provide a mechanism for sex dimorphism for the incidence of periodontal disease.

Abstract
This study aimed at evaluation of pro-inflammatory cytokine response (TNF-α, IL-1β and IL-17) in patients with chronic periodontitis administered per os with a probiotic strain of Lactobacillus reuteri. In the 38 adult patients with moderate chronic periodontitis, professional cleaning of teeth was performed. Two weeks after performing the oral hygienization procedures, clinical examination permitted to distinguish a group of 24 patients (Group 1) in whom treatment with probiotic tablets containing L. reuteri strain, producing hydrogen peroxide (Prodentis), was conducted. In the remaining 14 patients, no probiotic tablet treatment was applied (the control group; Group 2). From all patients in two terms, gingival crevicular fluid (GCF) was sampled from all periodontal pockets. Estimation of TNF-α, IL-lβ and IL-17 in GCF was performed using the ELISA method. After completion of the therapy with probiotic tablets, 18 (75 %) of the patients of Group 1 have manifested a significant decrease in levels of studied pro-inflammatory cytokines (TNF-α, IL-1β and IL-17). In parallel, we have detected an improvement of clinical indices [sulcus bleeding index (SBI), periodontal probing depth (PPD), clinical attachment level (CAL)]. At individuals of Group 2 levels of studies, pro-inflammatory cytokines and clinical indices (SBI, PPD, CAL) were significantly higher than in Group 1. Results obtained in this study indicate that application of oral treatment with tablets containing probiotic strain of L. reuteri induces in most patients with chronic periodontitis a significant reduction of pro-inflammatory cytokine response and improvement of clinical parameters (SBI, PPD, CAL). Therefore, such an effect may result in a reduced activity of the morbid process.

Abstract
Periodontal disease is a pathological condition that involves inflammation of the tooth supporting structures. It occurs in response to the presence of bacterial plaque on the tooth structure. The host defense system, including innate and adaptive immunity, is responsible for combating the pathologic bacteria invading the periodontal tissue. Failure to eradicate the invading pathogens will result in a continuous state of inflammation where inflammatory cells such as lymphocytes, PMNs, and macrophages will continue to produce inflammatory mediators in an effort to destroy the invaders. Unfortunately, these inflammatory mediators have a deleterious effect on the host tissue as well as foreign microbes. One of the effects of these mediators on the host is the induction of matrix degradation and bone resorption through activation of proteases and other inflammatory mediators that activate osteoclasts.

Abstract
Periodontitis is a chronic inflammatory condition of the periodontium involving interactions between bacterial products, numerous cell populations and inflammatory mediators. It is generally accepted that periodontitis is initiated by complex and diverse microbial biofilms which form on the teeth, i.e. dental plaque. Substances released from this biofilm such as lipopolysaccharides, antigens and other virulence factors, gain access to the gingival tissue and initiate an inflammatory and immune response, leading to the activation of host defence cells. As a result of cellular activation, inflammatory mediators, including cytokines, chemokines, arachidonic acid metabolites and proteolytic enzymes collectively contribute to tissue destruction and bone resorption. This review summarises recent studies on the pathogenesis of periodontitis, with the main focus on inflammatory mediators and their role in periodontal disease.

Peri-implant crestal bone loss: a putative mechanism. Int J Dent 2012; 2012:742439.

Abstract
Purpose. The immunological mechanisms of peri-implant crestal bone loss have, hitherto, not been elucidated. We hypothesized that bacterial products from the microgap cause upregulation of cytokines in otherwise healthy peri-implant cells, which results in osteoclast formation and, ultimately, in bone resorption. Materials and Methods. We used RT-PCR and ELISA to assay mediators of osteoclastogenesis in rat and human macrophages (r-and hMO); bone marrow derived stromal cells (r-and hBMCs); and human gingival fibroblasts (hGF)—with or without stimulation by LPS. TRAP positive multinucleate cells were assessed for their resorptive ability. Results. We show that IL-1α, IL-1β, and IL-6 were expressed by all examined cell types, and TNF-α was upregulated in hGF. Secretion of IL-1α and IL-1β proteins was stimulated in hMO by LPS, and IL-6 protein secretion was highly stimulated in hBMCs and hGF. Both LPS and RANKL stimulated macrophages to form osteoclast-like TRAP positive cells, which resorbed calcium phosphate substrates. Conclusion. Taken together, the results of our study support the hypothesis that bacterial endotoxins upregulate enhanced mediators of osteoclastogenesis in resident cells found in the healthy peri-implant compartment and that the local synergistic action of cytokines secreted by such cells results in the genesis of resorptively active osteoclasts.

Abstract
BACKGROUND AND OBJECTIVE There are few data concerning the effect of scaling and root planing on the levels of immune and inflammatory mediators in gingival crevicular fluid from patients with chronic periodontitis. Therefore, in this study the influence of scaling and root planing was determined on amounts of interleukin (IL)-1β, IL-8 and MMP-8 in gingival crevicular fluid from patients with chronic periodontitis, in relation to clinical parameters. MATERIAL AND METHODS A total of 51 patients were enrolled in this study. The study population consisted of 30 patients with generalized advanced chronic periodontitis, while 21 periodontally healthy subjects were recruited for the control group. The clinical parameters included approximal plaque index, gingival index, pocket depth and clinical attachment loss. The amounts of IL-1β, IL-8 and MMP-8 in gingival crevicular fluid were measured by ELISA. Periodontal parameters as well as gingival crevicular fluid humoral factor amounts were evaluated in the control group and in chronic periodontitis patients at baseline and at 1 and 4 wk after scaling and root planing treatment. RESULTS At baseline, there were significant differences between control subjects and chronic periodontitis patients in terms of clinical attachment loss, pocket depth, gingival index (p < 0.001) and approximal plaque index (p < 0.01). The amounts of IL-1β, MMP-8 (p < 0.001) and IL-8 (p < 0.01) in gingival crevicular fluid were significantly lower in healthy subjects than in chronic periodontitis patients. Scaling and root planing led to improvement in all examined clinical parameters, apart from clinical attachment loss. Periodontal treatment also resulted in a significant decrease in the amounts of IL-1β, IL-8 and MMP-8 in comparison to baseline, especially 4 wk after scaling and root planing (p < 0.001); however, the amounts of these humoral factors were still higher than those in control group. CONCLUSION Our observations indicated that short-term nonsurgical therapy resulted in a significant improvement in periodontal indices and in a marked decrease of IL-1β, IL-8 and MMP-8 gingival crevicular fluid levels. Nevertheless, no significant correlations were found between clinical parameters and amounts of humoral factors after therapy.

Abstract
It is now well accepted that besides the cholesterol associated mechanisms of atherogenesis, inflammation plays a crucial role in all stages of the development of the atherosclerotic lesion. This 'inflammation hypothesis' raises the possibility that through systemic elevations of pro-inflammatory cytokines, periodontal diseases might also contribute to systemic inflammation and, therefore, to atherogenesis. In fact, there is evidence that periodontal diseases are associated with higher systemic levels of high-sensitivity C-reactive protein and a low grade systemic inflammation. This phenomenon has been explained based on mechanisms associated with either the infectious or the inflammatory nature of periodontal diseases. The purposes of this article were to review (1) the evidence suggesting a role for oral bacterial species, particularly periodontal pathogens, in atherogenesis; (2) the potential mechanisms explaining an etiological role for oral bacteria in atherosclerosis; (3) the evidence suggesting that periodontal infections are accompanied by a heightened state of systemic inflammation; (4) the potential sources of systemic inflammatory biomarkers associated with periodontal diseases; and (5) the effects of periodontal therapy on systemic inflammatory biomarkers and cardiovascular risk.

Abstract
Both lesions of endodontic origin and periodontal diseases involve the host response to bacteria and the formation of osteolytic lesions. Important for both is the upregulation of inflammatory cytokines that initiate and sustain the inflammatory response. Also important are chemokines that induce recruitment of leukocyte subsets and bone-resorptive factors that are largely produced by recruited inflammatory cells. However, there are differences also. Lesions of endodontic origin pose a particular challenge since that bacteria persist in a protected reservoir that is not readily accessible to the immune defenses. Thus, experiments in which the host response is inhibited in endodontic lesions tend to aggravate the formation of osteolytic lesions. In contrast, bacteria that invade the periodontium appear to be less problematic so that blocking arms of the host response tend to reduce the disease process. Interestingly, both lesions of endodontic origin and periodontitis exhibit inflammation that appears to inhibit bone formation. In periodontitis, the spatial location of the inflammation is likely to be important so that a host response that is restricted to a subepithelial space is associated with gingivitis, while a host response closer to bone is linked to bone resorption and periodontitis. However, the persistence of inflammation is also thought to be important in periodontitis since inflammation present during coupled bone formation may limit the capacity to repair the resorbed bone.

Abstract
BACKGROUND AND OBJECTIVE Although many studies have appeared about diabetes mellitus-associated periodontitis, few have compared periodontitis inflammatory markers between type 1 (T1DM) and type 2 diabetes mellitus (T2DM), and information regarding this issue is scarce and contradictory. We evaluated the levels of plasma C-reactive protein and of interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumour necrosis factor-α (TNF-α) in gingival crevicular fluid in two groups of subjects affected by T1DM and T2DM, in order to identify possible differences between the two classes in the inflammatory mechanisms of diabetes mellitus-associated periodontitis. MATERIAL AND METHODS Plasma C-reactive protein and gingival crevicular fluid IL-1β, IL-6 and TNF-α were measured in periodontitis patients affected by type 1 (P-T1DM, n = 24) and type 2 diabetes mellitus (P-T2DM, n = 24). RESULTS Gingival crevicular fluid levels of IL-1β and TNF-α in P-T1DM subjects were significantly higher than in P-T2DM subjects. In P-T1DM subjects, we found significant negative correlations between the duration of diabetes mellitus and IL-1β and between the duration of diabetes mellitus and TNF-α. CONCLUSION This study shows that IL-1β and TNF-α levels in periodontitis patients with T1DM are affected by the duration of diabetes mellitus.

Abstract
AIMS To evaluate the interleukin-1 beta (IL-1 beta) levels in gingival crevicular fluid (GCF) and serum in either naturally occurring (N-O) or experimentally induced (E-I) plaque-associated gingivitis. MATERIAL AND METHODS Thirty-seven periodontally healthy subjects were evaluated in real life conditions (N-O gingivitis) as well as after 21 days of experimental gingivitis trial (E-I gingivitis). During the experimental gingivitis trial, in one maxillary quadrant (test quadrant), gingival inflammation was induced by oral hygiene abstention, while in the contralateral (control) quadrant, oral hygiene was routinely continued. IL-1 beta concentrations in N-O and E-I gingivitis were investigated for IL-1B(+3954) and IL-1B(-511) gene polymorphisms. RESULTS (i) GCF IL-1 beta concentrations in E-I gingivitis were significantly higher compared with N-O gingivitis; (ii) an intra-individual correlation between GCF concentrations of IL-1 beta detected in N-O and E-I gingivitis was observed in control quadrants, but not in test quadrants; (iii) IL-1 beta concentration in GCF was associated with IL-1B(+3954) genotype only at test quadrants; (iv) IL-1 beta was detectable in serum only at low levels in a limited number of subjects, without difference between gingivitis conditions. CONCLUSIONS Aspects of the bacterial challenge to the gingival tissues, such as the amount of plaque deposits and plaque accumulation rate, appear to affect the IL-1 beta levels in GCF in subjects with a specific IL-1B genotype.

Abstract
BACKGROUND The purpose of this study was to assess concentrations of angiopoietin (Ang)-1 at various stages of gingival inflammation. Ang-1 is an anti-inflammatory mediator present in various inflammatory diseases. However, its presence during the pathogenesis of gingival inflammation has not been established in vivo. METHODS Gingiva was obtained from 110 human donors before extraction of the adjacent teeth. The tissue was grouped based on adjacent probing depth and bleeding on probing (BOP). Gingiva adjacent to a <or=3-mm sulcus without BOP was classified as "normal" (N); gingiva adjacent to a 3-mm sulcus with BOP was classified as "diseased, slight" (DS); gingiva adjacent to a 4- to 6-mm sulcus featuring BOP was classified as "diseased, moderate" (DM); and gingiva adjacent to >6-mm sulci was classified as "diseased, severe" (DSev). Tissues were solublized, and concentrations of interleukin (IL)-1beta and -6, tumor necrosis factor (TNF)-alpha, endothelin (ET)-1, Ang-1, vascular cell adhesion molecule (VCAM)-1, and vascular endothelial growth factor (VEGF) were assessed by enzyme-linked immunosorbent assay. Data were compared by factorial analysis of variance, the post hoc Tukey test, and the Pearson correlation test. Groups were defined as significantly different when P <0.05. RESULTS Gingival concentrations of IL-1beta and -6, TNF-alpha, VEGF, and ET-1 were significantly greater, and VCAM-1 and Ang-1 were significantly lower, in DSev and DM than in N and DS tissues (P <0.05). In addition, gingival concentrations of IL-6, VEGF, and ET-1 were significantly greater, and VCAM-1 and Ang-1 were significantly lower, in DSev than in DM tissues (P <0.05). There were significant positive correlations among sulcular depth, IL-1beta and -6, TNF-alpha, VEGF, and ET-1 and negative correlations among VCAM-1, Ang-1, sulcular depth, and the other biomarkers (P <0.001). CONCLUSIONS Depleted tissue concentrations of Ang-1 may allow gingival inflammation to become more severe because VEGF and ET-1 secretion become less inhibited. Thus, the tissues become edematous and more likely to develop BOP.

Abstract
Matrix metalloproteinases (MMPs) play a key role in periodontal disease.
Although it is known that macrophages and fibroblasts are co-localized and
express MMPs in the diseased periodontal tissue, the effect of interaction
between these two cell types on MMP expression has not been well elucidated.
Furthermore although it is known that diabetes is associated with accelerated
periodontal tissue destruction, it remains unknown whether hyperglycemia, a
major metabolic abnormality in diabetes, regulates MMP expression by affecting
the cross-talking between fibroblasts and macrophages. In this study, human
gingival fibroblasts and U937 macrophages were cocultured in a two-compartment
transwell culture system, and the cells were treated with normal or high
glucose. We found that coculture of fibroblasts and U937 macrophages led to an
augmentation of MMP-1 expression by U937 macrophages, and high glucose further
enhanced this augmentation. Similar observations were also made in the
coculture of fibroblasts and human primary monocytes. We also found that
interleukin 6 (IL-6) released by fibroblasts was essential for the
augmentation of MMP-1 expression by U937 macrophages. Furthermore our results
showed that high glucose, IL-6, and lipopolysaccharide had a synergistic
effect on MMP-1 expression. Finally our study indicated that MAPK pathways and
activator protein-1 transcription factor were involved in the coculture- and
high glucose-augmented MMP-1 expression. In conclusion, this study
demonstrates that IL-6 derived from fibroblasts is essential for MMP-1
up-regulation by cross-talking between fibroblasts and U937 macrophages
exposed to high glucose, revealing an IL-6-dependent mechanism in MMP-1
up-regulation.

Abstract
The RgpA-Kgp proteinase-adhesin complexes of Porphyromonas gingivalis were observed, using immunostaining, in human gingival tissue associated with periodontitis but not in healthy tissue. The staining pattern suggested a concentration gradient from the subgingival plaque into the subjacent gingival connective tissue. Intense immunostaining was observed in areas displaying gross disturbance of tissue architecture. P. gingivalis cells and the RgpA-Kgp complexes at low concentrations were shown to stimulate secretory intercellular adhesion molecule 1, interleukin-8 (IL-8), IL-6, and macrophage chemoattractant protein secretion from cultured human epithelial (KB) and fibroblast (MRC-5) cells. However, at high concentrations a reduction in the level of these mediators was observed. In contrast, macrophage inflammatory protein 1alpha and IL-1alpha were stimulated only at high P. gingivalis cell concentrations. P. gingivalis cells and the RgpA-Kgp complexes were shown to induce apoptosis in KB and MRC-5 cells in a time- and dose-dependent manner. These data suggest that the RgpA-Kgp complexes penetrate the gingival connective tissue; at low concentrations distal from the plaque the complexes stimulate the secretion of proinflammatory mediators, while at high concentrations proximal to the plaque they induce apoptosis and attenuate the secretion of proinflammatory mediators.

Abstract
BACKGROUND AND OBJECTIVE While there is substantial information concerning the concentrations of interleukin-1 isoforms within gingival crevicular fluid, there is little information concerning their concentrations within either normal or diseased gingival tissues. Therefore, the aim of this study was to evaluate the relationship between the concentrations of gingival interleukin-1 isoforms and the adjacent sulcular depth. MATERIAL AND METHODS Interdental gingival papillae were excised and grouped based on adjacent pocket depth and the presence of bleeding on probing. Gingiva adjacent to a sulcus of < or = 3 mm without bleeding on probing were classified as 'normal'; gingiva adjacent to a 3-mm sulcus with bleeding on probing were classified as 'diseased-slight'; gingiva adjacent to a 4-6-mm sulcus featuring bleeding on probing were classified as 'diseased-moderate'; and gingiva adjacent to a sulcus of > 6 mm featuring bleeding on probing were classified as 'diseased-severe'. Tissues were solublized and the concentrations of interleukin-1beta, interleukin-1alpha, interleukin-1 receptor antagonist and interleukin-6 were assessed by enzyme-linked immunosorbent assay. Data were compared by factorial analysis of variance, the post-hoc Tukey test and the Pearson's correlation test. RESULTS Gingival concentrations of interleukin-6, interleukin-1 receptor antagonist, interleukin-1alpha- and interleukin-1beta were significantly greater at diseased-severe sites than at normal, diseased-slight, or diseased-moderate sites (p < 0.05); the gingival concentrations of interleukin-1 receptor antagonist and interleukin-1alpha were significantly greater at diseased-severe than at diseased-moderate sites (p < 0.05). Interleukin-1 receptor antagonist concentrations were significantly correlated with both interleukin-1alpha and interleukin-1beta concentrations. The ratios of concentrations of the interleukin-1 isoforms were different at the various stages of inflammation. CONCLUSION Our data indicated a progressive increase in gingival concentrations of interleukin-1 isoforms with increased adjacent sulcular depth. However, within 'diseased' tissues, the proportional concentrations of interleukin-1alpha and -beta to interleukin-1 receptor antagonist were lowest within diseased-severe tissues.

Abstract
BACKGROUND The primary aim of this study was to compare the inflammatory activity in the gingival crevicular fluid (GCF) in a group of patients with rheumatoid arthritis (RA) and a group of matched controls. Secondarily, we aimed to evaluate the effect of rheumatologic treatment on periodontal inflammation. METHODS Seventeen individuals with RA with a mean duration of disease of 12.1 (+/- 9.9) years and the same number of systemically healthy individuals matched for age, gender, periodontal status, and tobacco use were selected. Medication data were registered, and GCF was collected by means of an intracrevicular washing method. Besides clinical registrations, periodontal inflammation was assessed by analysis of the cytokines interleukin (IL)-1beta and -18 and of elastase activity. RESULTS Amounts of IL-1beta and total elastase were significantly lower in the patient group. IL-1beta and total elastase had a significant and strong correlation in the RA group (r(s) = 0.883). This correlation was not observed in the control group. CONCLUSION The anti-inflammatory treatment taken by RA patients might influence the periodontal inflammation status represented by IL-1beta and elastase in the GCF.

Abstract
BACKGROUND The presence of interleukin (IL)-23 has not been reported within inflamed gingiva, so we evaluated its concentration within gingiva from normal sites and sites of chronic periodontal disease. METHODS Gingiva was obtained prior to extraction of teeth. It was grouped based on clinical attachment loss (CAL): 0 to 2 mm (normal-slight), 3 to 4 mm (moderate), and >5 mm (severe). Tissues were solubilized, and IL-12, -23, -6, -17, and -1beta; interferon-gamma (IFN-gamma); and tumor necrosis factor-alpha (TNF-alpha) concentrations were assessed by enzyme-linked immunosorbent assay. Data were compared by factorial analysis of variance, post hoc Tukey test, and Pearson correlation test. Groups were defined as significantly different when P <0.05. RESULTS The gingival concentrations of IL-23, -17, -1beta, and -6 and IFN-gamma were significantly greater at moderate CAL sites than at normal-slight CAL sites. Gingival concentrations of IL-23, -1beta, -17, and -6 and TNF-alpha were significantly greater at severe CAL sites than at normal-slight CAL sites. In addition, the gingival concentrations of IL-23, -17, and -6 and TNF-alpha were significantly greater and the gingival concentrations of IL-12 and IFN-gamma were significantly lower at severe CAL sites than at moderate CAL sites. Gingival concentrations of IL-23, -17, -6, and -1beta and TNF-alpha correlated positively with CAL. The IL-23 gingival concentration correlated significantly with IL-17, -1beta, and -6 and TNF-alpha concentrations and correlated negatively with IL-12 and IFN-gamma concentrations. CONCLUSIONS Our results suggested the possibility that the IL-23/IL-17 immune response was present within chronically inflamed gingiva. This is a host response that had not been reported previously in periodontal disease and may be an important factor in the chronic nature of the disease.
