Objective. Our aim in this paper was to investigate the possible genetic association between three Ser563Asn, Leu125Val and Arg670Gly polymorphisms of the PECAM-1 gene and periodontitis. Methods. Genomic DNA was isolated from whole blood of 105 periodontal patient (52 with chronic periodontitis and 53 with aggressive periodontitis) and 101 healthy individuals. Samples were genotyped and analyzed for the three single-nucleotide polymorphisms (SNPs) of PECAM-1 using polymerase chain reaction with sequence-specific primers (PCR-SSPs). Results. A statistically significant difference was found between the genotypic distribution of the Ser563Asn polymorphism in patients with periodontitis compared to controls (P=0.02). But there were no statistically significant difference between the allele frequencies in the different groups (P=0.05). The other two polymorphisms did not show a statistically significant difference in their allele and genotype frequencies between the groups. There was no statistically significant difference found for any of the polymorphisms allele and genotype distribution in aggressive and chronic periodontitis either. Conclusions. No significant association was found between the polymorphism tested and the subgroups of periodontitis, further research is still necessary to determine whether this polymorphism can be used as a genetic marker of periodontitis.

ABSTRACT Introduction The clinical manifestation of periodontal diseases (such as gingivitis and chronic periodontitis) results from a complex interplay between the etiologic agents such as bacteria that present in the dental plaque, genetic factors, systemic diseases, smoking and exposure of some heavy metals, such as mercury. In this study, we aimed to evaluate hair mercury levels in healthy subjects in comparison with periodontal patients. Materials and methods One hundred twenty subjects were enrolled in this study. The included persons were divided into 3 groups: healthy subjects (n = 40), gingivitis (n = 40) and chronic periodontitis patients (n = 40). Hair samples were collected from occipital area of head. Total mercury levels were determined by atomic absorption spectrophotometry. Results The difference between mercury levels in three groups were statistically significant (p-value < 0.001). Mercury level in periodontitis patients was greater than the gingivitis group (p-value < 0.001). In addition the differences between mercury levels in periodontitis patients vs healthy individuals was significant (p-value = 0.048). The gingivitis patients had lower levels of mercury than the control group, but the difference was not significant (p-value = 0.170). Conclusion The results showed that the levels of mercury are to some extent differed in periodontal diseases in comparison with the healthy individuals. A study with larger sample size is needed for clarification of this issue. How to cite this article Roushan HH, Parsian H, Alijannia R, Mosapour A, Khafri S.

Purpose: Promising advances have been made in mesenchymal stem cell transplantation to re-induce the immune tolerance in neuroinflammatory animal models and Multiple Sclerosis patients. The available evidence demonstrated that immunomodulatory effects of mesenchymal stem cell are particularly exerted through releasing exosomes to their environment. We therefore, aimed to comparatively assess the potential effect of mesenchymal stem cells and mesenchymal stem cells-derived exosomes on proliferation and function of the CD4+CD25− conventional T cells, isolated from relapsing-remitting Multiple Sclerosis patients. Methods: Mesenchymal stem cells were isolated from human umbilical cord tissues and used for exosome isolation via ultracentrifugation. Both mesenchymal stem cells and mesenchymal stem cells-derived exosomes were evaluated for their anti-inflammatory effects against the proliferation of T cells isolated from two groups of individuals in vitro, MS patients and healthy subjects. Cytokine production of conventional T cells (interferon-γ, interleukin-10, and interleukin-17) was also assessed, using flow cytometry for the patients and healthy individuals. Results: Here, evidence shows that MSCs and MSC-derived exosomes dampen proliferation and percentage of conventional T cells that produce IFN-γ (healthy control: p<0.001) and interleukin-17 (healthy control: p<0.001, MS patients: p<0.001), with a significant increase of IL-10 producing cells in the patients and healthy individuals. Surprisingly, MSC-derived exosomes demonstrated higher immune-modulating properties on conventional T cells responses, compared to MSCs. Conclusion: The current study, provides a novel approach of exocytosis on autoimmune therapy. In particular, Mesenchymal stem cell -derived exosomes, which are cell-derived biologics, could be considered as an alternative for Mesenchymal stem cells in treating multiple sclerosis.
