chronic periodontitis bacteria

Gingipain proteases of P. gingivalis activate NF-κB and MMP-9 in oral squamous carcinoma cells, which is important for cancer cell invasion and metastasis [159, 160].

This is important, since these cytokines are related to the stimulation of osteoclasts and bone resorption [58]. A. Finally, GroEL produced by P. gingivalis increases tumor volume and the mortality of mice implanted with the mouse colon carcinoma cell line (C26) [161]. This is interesting, since in addition to P. gingivalis, other periodontitis-associated taxa have been associated with orodigestive cancers. In the construction of explanatory models of the etiopathogenesis of periodontal disease, autoimmune mechanisms were among the first to be explored and historically, … P. gingivalis interacts with the GECs through the TLRs mediated by the recognition of P. gingivalis virulence factors such as fimbria and the LPS. Periodontitis is a gum disease. Antibiotics have been shown to have value in reducing the need for periodontal surgery in patients with chronic periodontitis. A. Dye, L. Wei et al., “Prevalence of periodontitis in adults in the United States: 2009 and 2010,”, S. Schultz-Haudt, B. G. Bibby, and M. A.

Socransky, A. D. Haffajee, C. Smith et al., “Use of checkerboard DNA-DNA hybridization to study complex microbial ecosystems,”, P. D. Marsh, “Are dental diseases examples of ecological catastrophes?”, P. D. Marsh, D. A. Either way, there is extensive evidence showing that species such as Porphyromonas gingivalis (highly abundant and prevalent in periodontitis) and Fusobacterium nucleatum (closely interacting with periodontitis-associated species in the disease) directly activate transduction pathways leading to cell transformation [7–12]. Association of periodontal bacteria with orodigestive cancer. [153] showed that oral administration of P. gingivalis induces changes in the ileal microbiota in a mouse model, increasing systemic inflammation. The inflammation is so severe that pockets of air also develop between your gums and teeth. T cells promote a profile characterized by CD8+ and CD4+ cells that generate a proinflammatory medium rich in cytokines such as tumor necrosis factor alpha (TNF-α), interleukin- (IL-) 1, IL-4, IL-10, interferon-γ (IFN-γ), and transforming growth factor β (TGF-β) [41].

Several virulence factors are involved in the direct activation of inflammation and cell proliferation mediated by P. gingivalis [6]. Through such studies, nowadays, we have a good understanding of its role in the pathogenesis of periodontitis. In the periodontitis-associated group of bacteria, species such as Filifactor alocis, P. gingivalis, Porphyromonas endodontalis, T. forsythia, and T. denticola are found in all the 4 studies reviewed. Thus, the whole dysbiotic community will synergistically initiate processes of tissue inflammation, activate production of cytokines, and initiate the recruitment of immune cells [28]. Moreover, synergistic interactions between F. nucleatum and two periodontitis-associated bacteria, T. denticola and P. gingivalis, have been reported in chronic periodontitis [149]. Interestingly, an increased expression of IL-8, C-X-C motif chemokine ligand 3 (CXCL-3), CXCL-1, IL-1, IL-6, colony-stimulating factor 2 (CSF2), and TNF-α was observed in cells stimulated with the multispecies biofilms. For example, studies using T. denticola monoinfections have shown that the bacterium can activate Toll-like receptor 5 (TLR5) through the flagellin, the main component of the bacterial flagellum. In 1954, it was proposed that the accumulation of microorganisms promotes the release of compounds that produce inflammation in the gingival tissue [18, 19]. Over time, plaque builds up and eventually leads to periodontitis. The disease is characterized by an inflammatory response to commensal and pathogenic oral bacteria. Unfortunately, w… Moreover, since bacterial spreading to distant sites on the human body occurs in coexistence, it is relevant to know the synergistic or antagonistic effects that these interactions may have in oral and extra oral carcinogenesis. (ii)Rheumatoid arthritis (RA): RA is an autoimmune disease characterized by the thickening of the synovium, a tissue that exists inside the joints. [1] Among them, these bacteria can induce NF-κB-mediated responses, promote cell survival, activate oncogenic pathways, reduce proapoptotic proteins expression, increase cell migration and invasion, increase the expression of EMT-associated proteins, enhance metastasis, etc. Additionally, the direct effect of periodontitis-associated bacteria as well as other subgingival microorganisms equally prevalent both in healthy and diseased subjects “core species” contributes to the chronicity of the disease through the activation of specific inflammatory pathways. A deeper explanation of such associations and possible mechanisms involved in these associations will be addressed in following paragraphs. Chronic and aggressive periodontitis have been suggested to harbour different types of subgingival microbiotas; while P. gingivalis is considered the major pathogen in chronic periodontitis in adults, A. actinomycetemcomitans is seen as the key pathogen in aggressive periodontitis, especially in its localized form in adolescence.
