The lipoteichoic acid of Lactobacillus plantarum effect on lymphocyte, VEGF-A and TGF-β expression in male rat dental pulp
Objective
Lipoteichoic acid from Lactobacillus plantarum (L. plantarum) is a significant virulence factor that exacerbates pulp inflammation. Lipoteichoic acid plays a role in modulating the inflammatory to proliferative phase transition is crucial in determining the outcome of pulp healing or necrosis. This study explores the role of L. plantarum on lymphocytes and the expression of transforming growth factor β1 (TGF-β1) and vascular endothelial growth factor A (VEGF-A) in a male rat model of acute dental pulp injury.
Design
The acute dental pulp model was created in the upper molar of Rattus novergicus using a round bur. Then, the dental pulp was exposed to 10 µg/ml of the lipoteichoic acid of L. plantarum and filled with a temporary filling. In the next 24, 48, and 72 h, each animal was decapitated, and the expression of TGF-β1 and VEGF-A in dental pulp was analyzed using indirect immunohistochemistry, while the lymphocytes analyzed using hematoxyline-eosin staining.
Result
Lipoteichoic acid of L. plantarum induced acute dental pulp by increasing the lymphocyte number after 48 and 72 h of exposure (p < 0.05). While, inhibiting TGF-β1 expression after 48 and 72 h of exposure (p < 0.05), and VEGF-A was inhibiting after 72 h of exposure (p < 0.05).
Conclusion
Exposure to lipoteichoic acid from L. plantarum significantly accelerates the inflammatory response in the dental pulp. However, this accelerated inflammation disrupts the proliferative phase, potentially leading to more extensive damage to the dental pulp.
期刊介绍：
The journal Cytokine has an open access mirror journal Cytokine: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
* Devoted exclusively to the study of the molecular biology, genetics, biochemistry, immunology, genome-wide association studies, pathobiology, diagnostic and clinical applications of all known interleukins, hematopoietic factors, growth factors, cytotoxins, interferons, new cytokines, and chemokines, Cytokine provides comprehensive coverage of cytokines and their mechanisms of actions, 12 times a year by publishing original high quality refereed scientific papers from prominent investigators in both the academic and industrial sectors.
We will publish 3 major types of manuscripts:
1) Original manuscripts describing research results.
2) Basic and clinical reviews describing cytokine actions and regulation.
3) Short commentaries/perspectives on recently published aspects of cytokines, pathogenesis and clinical results.
