Toll-Like Receptors 1/2/4/6 and Nucleotide-Binding Oligomerization Domain-Like Receptor 2 Are Key Damage-Associated Molecular Patterns Sensors on Periodontal Resident Cells

چکیده
Background: Toll-like receptors (TLRs) and nucleotide-binding oligomerization domain (NOD)-like (NLRs) are innate, damage-associated molecular patterns (DAMP) sensors. Their expressions in human periodontal resident cells reactions toward irritations, such as hypoxia lipopolysaccharide (LPS), remain not well characterized. This cross-sectional study aimed to investigate characterize TLRs, NOD1/2 NLRP1/2 at the dento-gingival junction. Methods: Immunohistochemistry screening was carried out on tissue biopsies sections, while selected DAMP sensors signal protein expression under Escherichia coli LPS (2 µg/mL) and/or (1% O2), 24 h, by gingival keratinocytes (HGK) or fibroblasts (HGF) were investigated. Results: Positive TLR1/2/4/5/6, immunostaining observed healthy periodontitis with apparently more pocket epithelial positive for TLR2, TLR4 NOD1/2. TLR1-6, messengers detected gingival/periodontal HGK HGF explants. induced signals upregulation of NOD2 HGKs TLR1/6 HGFs. Conclusion: Transcripts proteins expressed health disease. Putting all observations together, NOD2, perhaps TLR1/2/4/6, might be considered key, pattern cells.

Biocomputational analysis of evolutionary relationship between toll-like receptor and nucleotide-binding oligomerization domain-like receptors genes
AIM The active domains (TIR and NACHT) of the pattern recognition receptors (PRRs: Toll-like receptors [TLRs] and nucleotide-binding oligomerization domain [NOD]-like receptors [NLR], respectively) are the major hotspots of evolution as natural selection has crafted their final structure by substitution of residues over time. This paper addresses the evolutionary perspectives of the TLR and NLR...

Background: Multiple sclerosis (MS) is a T cell mediated autoimmune disease with unknown etiology. Appropriate MS therapeutic strategies need thorough understanding of both disease etiology and pathogenesis mechanisms. Ligation of TLR-2 and TLR-4 stimulates the production of several cytokines leading to CNS autoimmunity and neurodegenerative diseases. Objective: To find a relationship between M...
متن کاملToll-like receptors and damage-associated molecular patterns: novel links between inflammation and hypertension.
Low-grade systemic inflammation is a common manifestation of hypertension; however, the exact mechanisms that initiate this pathophysiological response, thereby contributing to further increases in blood pressure, are not well understood. Aberrant vascular inflammation and reactivity via activation of the innate immune system may be the first step in the pathogenesis of hypertension. One of the...
