Expression and Activity of Matrix Metalloproteinase-2 (MMP-2) in the development of rat first molar tooth germ

Brazilian Dental Journal, 2002
Tooth germ development is associated with morphological and biochemical changes of the dental papilla and enamel organ. Enzymes with gelatinolytic activities were studied by semiquantitative reverse transcriptase-polymerase chain reaction (RT-PCR) and ...

Systemic, Lifestyle and Environmental Modifying Factors in the Pathogenesis of Periodontitis

Journal of Periodontal Research, EarlyView.
A variety of impacting factors in the pathogenesis of periodontitis exist, including systemic, lifestyle, and environmental factors. This review highlights the manifold mechanistic aspects of the link between the pathogenesis of periodontitis, addressing these numerous factors to supplement the long‐standing knowledge of the progression of the disease.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Profiling and functional characterization of long noncoding RNAs during human tooth development

International Journal of Oral Science
The regulatory processes in developmental biology research are significantly influenced by long non-coding RNAs (lncRNAs). However, the dynamics of lncRNA expression during human tooth development remain poorly understood.

Autoimmunity and Periodontitis

Journal of Periodontal Research, EarlyView.
In a microbe‐driven inflammatory environment, peptidyl‐arginine deiminase (PAD) enzymes from neutrophils and Porphyromonas gingivalis citrullinate both microbial and self‐antigens. B cell presentation of citrullinated or self‐mimicking epitopes activates T cells that assist B cells in antibody isotype switching, affinity maturation, epitope spreading ...

Myeloid A20 Regulates Periodontal Tissue Integrity and Temporomandibular Joint Structure

Journal of Periodontal Research, EarlyView.
Dysregulation of A20 signaling has been implicated in several immune‐mediated diseases, including rheumatoid arthritis and psoriasis, conditions characterized by excessive NF‐κB activation and inflammatory tissue damage. The structural alterations observed in this model suggest that impaired regulation of innate immune signaling may increase ...
