Abstract

Insights

Tumour necrosis factor (TNF) receptors in gingival crevicular fluid (GCF) increase with chronic periodontitis (CP) severity. An imbalance between soluble TNF receptor type 1 and 2 in GCF may indicate CP progression.

Area of Science:

  • Periodontology
  • Immunology
  • Biochemistry

Background:

  • Soluble tumour necrosis factor (TNF) receptors type 1 and 2 modulate TNF-alpha-mediated inflammation in chronic periodontitis (CP).
  • Understanding these receptor levels in CP is crucial for inflammatory response insights.

Purpose of the Study:

  • To investigate and compare levels of TNF-alpha, soluble TNF receptor type 1, and soluble TNF receptor type 2.
  • To analyze these levels in gingival crevicular fluid (GCF) and serum of healthy individuals and CP patients.

Main Methods:

  • Collected 38 serum and 73 GCF samples from 16 healthy subjects and 22 CP patients.
  • Quantified TNF-alpha, soluble TNF receptor type 1, and soluble TNF receptor type 2 using enzyme-linked immunosorbent assay.
  • Analyzed GCF from sites with varying probing pocket depths (PPD).

Main Results:

  • TNF-alpha, soluble TNF receptor type 1, and soluble TNF receptor type 2 levels in GCF significantly increased with probing pocket depth (PPD).
  • Soluble TNF receptor type 2 levels were lower than type 1 as pocket depths increased.
  • The ratio of soluble TNF receptor type 2 to type 1 in GCF decreased significantly with increasing periodontitis severity.

Conclusions:

  • The observed imbalance between soluble TNF receptor type 1 and 2 levels in GCF correlates with chronic periodontitis severity.
  • This imbalance may serve as a potential biomarker for assessing CP progression.

The Oral Microbiota

The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...

Inflammatory Bowel Disease II: Ulcerative Colitis

Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal BarrierA...
Chronic Inflammation: Introduction01:12

Chronic Inflammation: Introduction

Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
