Levels of Gene Expression of Immunological Biomarkers in Peri-Implant and Periodontal Tissues. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17239100. [PMID: 33291232 PMCID: PMC7730812 DOI: 10.3390/ijerph17239100] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 10/31/2020] [Revised: 11/25/2020] [Accepted: 11/30/2020] [Indexed: 02/06/2023]
Abstract
This study compared the gene expression of the immunoinflammatory markers interleukin (IL)-6, IL-1ß, and tumor necrosis factor alpha (TNF-α), the matrix metalloproteinases (MMP)-1, -2, -8, and -9, and the tissue inhibitors of matrix metalloproteases (TIMP)-1 and -2 in the gingival tissue of individuals with periodontal and peri-implant disease. The study population included individuals with four periodontal statuses: periodontal health (PH group, n = 20); periodontitis (P group, n = 20); peri-implant health (PIH group, n = 20), and peri-implantitis (PI group, n = 20). Gingival biopsies were collected from one tooth per patient according to the inclusion criteria of each group. The mRNA levels of IL-6, IL-1ß, TNF-α, MMP-1, MMP-2, MMP-8, MMP-9, TIMP-1, and TIMP-2 were evaluated by qPCR. The levels of IL-1ß were significantly higher in the PI group when compared to the other groups (p < 0.05), while the levels of IL-6 were significantly higher in the groups with periodontal and peri-implant disease when compared with the healthy groups (p < 0.05); however, the levels of IL-6 did not differ between the PI and P groups (p > 0.05). For all other studied biomarkers, no significant differences were observed between groups (p > 0.05). IL-6 and IL-1ß presented higher levels of mRNA in diseased periodontal and peri-implant tissues. However, the expression of metalloproteinases and their inhibitors did not differ between the different periodontal statuses.

Int J Implant Dent 2020; 6:29. [PMID: 32719900 PMCID: PMC7385050 DOI: 10.1186/s40729-020-00230-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2020] [Accepted: 05/25/2020] [Indexed: 11/23/2022] Open
Abstract
Purpose The aim of the present retrospective study was to evaluate clinical and radiological outcomes, in terms of implant survival rate, marginal bone loss, and peri-implantitis incidence, of a titanium implants with an innovative laser-treated surface. Materials and methods A total of 502 dental implants were inserted in four dental practices (Udine, Arezzo, Frascati, Roma) between 2008 and 2013. All inserted implants had laser-modified surface characterized by a series of 20-μm-diameter holes (7–10 μm deep) every 10 μm (Synthegra®, Geass srl, Italy). The minimum follow-up period was set at 1 year after the final restoration. Radiographs were taken after implant insertion (T0), at time of loading (T1), and during the follow-up period (last recall, T2). Marginal bone loss and peri-implant disease incidence were recorded. Results A total of 502 implants with a maximum follow-up period of 6 years were monitored. The mean differential between T0 and T2 was 0.05 ± 1.08 mm at the mesial aspect and 0.08 ± 1.11 mm at the distal with a mean follow-up period of 35.76 ± 18.05 months. After being in function for 1 to 6 years, implants reported varying behavior: 8.8% of sites did not show any radiographic changes and 38.5% of sites showed bone resorption. The bone appeared to have been growing coronally in 50.7% of the sites measured. Conclusion Implants showed a maintenance of marginal bone levels over time, and in many cases, it seems that laser-modified implant surface could promote a bone growth. The low peri-implant disease incidence recorded could be attributed to the laser titanium surface features that seem to prevent bacterial colonization. Future randomized and controlled studies are needed to confirm the results of the present multi-centrical retrospective analysis.

Abstract
AIM To evaluate biological behavior of human peripheral mononuclear cells (PBMC) in contact with porous tantalum (PT) and Porphyromonas gingivalis (Pg). METHODS Pg was incubated for 8 hours. The groups formed were: PBMC (control), PBMC + PT, PBMC + Pg and PBMC + PT + Pg. Cell viability was evaluated using MTT assay. The morphology and adhesion of PBMC to PT was evaluated using scanning electron microscopy. Expression of interleukin (IL)-10, transforming growth factor (TGF)-β, matrix metallopeptidase (MMP)-9 and receptor activator of nuclear factor-κΒ ligand (RANKL) was determined by enzyme-linked immunosorbent assay. RESULTS MTT assay revealed that PT did not interfere in the mitochondrial activity of PBMC (P > .05). Scanning electron microscopy showed the adherence of PBMC to PT. IL-10 levels in PBMC + PT were similar to PBMC and lower than PBMC + Pg. TGF-β levels in PBMC + PT were higher than PBMC and PBMC + Pg. MMP-9 levels in PBMC + PT were similar to PBMC and lower than PBMC + Pg and PBMC + PT + Pg. RANKL levels in PBMC + PT were lower than in PBMC. CONCLUSION PT did not affect PBMC viability, allowed cell adhesion, reduced expression of RANKL and enhanced TGF-β in comparison with the control group.

Abstract
In HNSCC, protein- and mRNA-expression of the antileukoproteinase SLPI are significantly inverse correlated with HPV-infection suggesting that elevated expression of SLPI protects against HPV-infections. Moreover, SLPI-expression is up-regulated in HNSCC-patients reporting a smoking habit. Here, we investigate the described correlation in other HPV-driven cancers, namely vulvar squamous cell carcinoma (VSCC). FFPE samples of 99 VSCC were analyzed by PCR for HPV-DNA-expression and by RT-qPCR for SLPI-mRNA-expression. Of 99 VSCC 10 (10.1%) are HPV-positive; 9 were HPV16; 1 HPV18; all were E6/E7 mRNA-positive. 33 of the 99 patients (33.3%) reported a smoking habit; 7 (21.1%) of these were HPV-positive. Of 66 (66.7%) non-smokers 3 (4.5%) were HPV-positive. SLPI-expression was 4.0-fold lower in HPV-positive than HPV-negative patients. Smoking resulted in 2.3-fold higher SLPI expression. The data presented here indicate that SLPI plays a pivotal role in HPV-infection not only in HNSCC but also in VSCC and possibly also in other HPV-driven cancers. This however, needs to be analyzed in future studies. Furthermore these data lead to the hypothesis that the smoking induced SLPI-increase is systemic rather than local, as assumed based on the HNSCC data.

Abstract
Previously, the expression of a non-secreted IL-4 variant (IL-4δ13) has been described in association with apoptosis and age-dependent Th2 T-cell polarization. Signaling pathways involved in this process have so far not been studied. Here we report the induction of IL-4δ13 expression in human γδ T-cells upon treatment with a sublethal dose of histone deacetylase (HDACi) inhibitor valproic acid (VPA). Induction of IL-4δ13 was associated with increased cytoplasmic IL-4Rα and decreased IL-4 expression, while mRNA for mature IL-4 was concomitantly down-regulated. Importantly, only the simultaneous combination of apoptosis and necroptosis inhibitors prevented IL-4δ13 expression and completely abrogated VPA-induced global histone H3K9 acetylation mark. Further, our work reveals a novel involvement of transcription factor c-Jun in the signaling network of IL-4, HDAC1, caspase-3 and mixed lineage kinase domain-like protein (MLKL). This study provides novel insights into the effects of epigenetic modulator VPA on human γδ T-cell differentiation.

Abstract
OBJECTIVES The etiology of the reduced marginal bone loss observed around platform-switched implant-abutment connections is not clear but could be related to the release of variable amounts of corrosion products. The present study evaluated the effect of different concentrations of metal ions released from different implant abutment couples on osteoblastic cell viability, apoptosis and expression of genes related to bone resorption. METHODS Osteoblastic cells were exposed to five conditions of culture media prepared containing metal ions (titanium, aluminum, vanadium, cobalt, chromium and molybdenum) in different concentrations representing the amounts released from platform-matched and platform-switched implant-abutment couples as a result of an earlier accelerated corrosion experiment. Cell viability was evaluated over 21days using the Alamar Blue assay. Induction of apoptosis was measured after 24h of exposure using flow cytometry. Expression of interleukin-6, interleukin-8, cyclooxygenase-2, caspase-8, osteoprotegerin and receptor activator of nuclear factor kappa-B ligand (RANKL) by osteoblastic cells were analysed after exposure for 1, 3 and 21days using real-time quantitative polymerase chain reaction assay RESULTS: Metal ions in concentrations representing the platform-matched groups led to a reduction in cell viability (P<0.01) up to 7days of exposure. Stimulated cells showed higher rates of early apoptosis (P<0.01) compared to non-treated cells. Metal ions up-regulated the expression of interleukin-6, interleukin-8, cyclooxygenase-2 and RANKL in a dose dependent manner after 1day of exposure (P<0.05). The up-regulation was more pronounced in the groups containing the corrosion products of platform-matched implant-abutment couples. CONCLUSION Osteoblastic cell viability, apoptosis, and regulation of bone resorbing mediators were significantly altered in the presence of metal ions. The change in cytokine levels expressed was directly proportional to the metal ion concentration. CLINICAL SIGNIFICANCE The observed biological responses to decreased amounts of metal ions released from platform-switched implant-abutment couples compared to platform-matched couples may partly explain the positive radiographic findings in respect to crestal bone level when utilising the "platform-switching" concept, which highlights the possible role of corrosion products in the mediation of crestal bone loss around dental implants.

Abstract
In order to confirm the inverse correlation between secretory leucocyte protease inhibitor (SLPI) expression, and human papillomavirus (HPV) infection previously observed in head and neck squamous-cell carcinoma, the present study retrospectively investigated the association between SLPI and Annexin A2 (AnxA2) expression, and HPV status in non-neoplastic chronic tonsillitis (n=118), and tonsillar hyperplasia (n=96) tissue. We hypothesised that smoking induces the upregulation of SLPI, resulting in reduced binding of HPV to AnxA2, a known modulator of HPV entry into the cell. SLPI and cyclin-dependent kinase inhibitor 2A (p16INK4A) protein expression was measured using immunohistochemistry in 214 specimens; SLPI and AnxA2 gene expression was measured using reverse transcription-quantitative polymerase chain reaction in 213 cases; and DNA was isolated from all the specimens to determine HPV status. The association between the results of the aforementioned analyses and the smoking habits of patients was analysed. The samples were HPV-negative. p16INK4A expression demonstrated moderate and strong staining in 38, and 0 cases, respectively. SLPI expression presented negative, weak and moderate signals in 163, 45, and 6 cases, respectively. A positive correlation was identified between smoking and SLPI (P=0.0001). Gene expression analysis (n=213) revealed that smoking (n=48) resulted in a significant increase in SLPI and AnxA2 expression. A significant positive correlation between AnxA2 and SLPI, indicating a surplus of AnxA2 in relation to SLPI, was exclusively identified in non-smokers. The data demonstrated that smoking results in increased SLPI and AnxA2 expression also in non-neoplastic tonsillar tissue. The observed surplus of AnxA2 in relation to SLPI identified exclusively in the tonsillar tissue of non-smokers indicates a higher possibility of a successful HPV infection of the tonsillar tissue of non-smokers, given the properties of AnxA2 to function as an infection modulator.

Abstract
Recently, we demonstrated a significant inverse correlation between HPV-infection and SLPI-expression suggesting that SLPI protects against HPV-infection of HNSCC. Here we analyzed in a single lab setting 307 formalin-fixed paraffin-embedded HNSCC cases (tonsillar n = 135; non-tonsillar: n = 172) from eight health care centers. Samples were analyzed for SLPI gene- and protein-expression. Annexin A2, its heterotetramer A2t, putatively facilitating HPV- and SLPI-cell entry, was measured to study the correlation between SLPI and annexin A2. Data were correlated with tobacco consumption and HPV-status. Overall, HPV-DNA prevalence was 23.5% (72/307); attributed to: 43.7% (59/135) tonsillar and 7.6% (13/172) non-tonsillar cases. Smoking resulted in 6.44-fold increased and HPV-infection in 3.46-fold decreased SLPI-gene expression in all HNSCC with similar significant results obtained in tonsillar and non-tonsillar SCC separately. Correlating annexin A2- and SLPI-gene expression showed a significant surplus of annexin A2 in HPV-positive tumors (4.21× more annexin A2) and 6.72× more annexin A2 than SLPI in nonsmokers in all HNSCCs and similar significant results for both tumor entities separately. The surplus of annexin A2 in non-smokers and HPV-positive patients supports our hypothesis that decreased SLPI levels facilitate HPV-infection i.e., increased SLPI-expression may protect against HPV-infection of tonsillar and non-tonsillar SCC.

Abstract
Recently, we showed that increased SLPI levels prevent human papillomavirus (HPV) infections and metastasis in smoking-induced, non-HPV-driven head and neck squamous cell carcinoma (HNSCC). Here, we focus on the role of SLPI in non-HPV-driven HNSCC, investigating tumor tissue and non-neoplastic mucosa from the same patients and from non-HNSCC patients. Gene and protein expression of SLPI and gene expression of annexin 2 (a SLPI receptor), nicotine receptor (α7AChR) and arylhydrocarbon receptor (AhR) were analyzed in HNSCC patients (20 smokers; 16 nonsmokers). SLPI-results were correlated with the patients' HPV status. Non-neoplastic mucosa of HNSCC patients and normal mucosa from non-HNSCC individuals (18 smokers; 20 nonsmokers) was analyzed for the same parameters. Tissue of the inferior turbinate (n = 10) was incubated with nicotine for analysis of the same genes. SLPI gene expression in tumor tissue was 109.26 ± 23.08 times higher in smokers versus nonsmokers. Non-neoplastic mucosa of smokers showed also higher SLPI gene expression (10.49 ± 1.89-fold non-HNSCC; 18.02 ± 3.93-fold HNSCC patients). Annexin 2 gene expression was also increased in smokers. SLPI data were corroborated by immunohistochemistry. A nicotine dependent correlation between SLPI and annexin 2 gene expression (r(2) = 0.15, p < 0.001) was shown ex vivo. Nicotine and smoking increased α7AChR and AhR gene expression. Five patients, showing no/low SLPI expression, were HPV16-positive. A significant correlation between smoking and SLPI expression in tumors and to our knowledge for the first time in mucosa of HNSCC and non-HNSCC patients was established. Together with the finding that all patients with HPV infection showed no/low SLPI expression, these data support our intriguing hypothesis that smoking induced upregulated SLPI prevents HPV infections.
