AAP gives honorary membership to EFP treasurer Joerg Meyle
The American Academy of Periodontology (AAP) has given its Honorary Membership Award to Joerg Meyle, professor and chair of the department of periodontology at the Justus-Liebig University in Giessen, Germany, and treasurer of the EFP.
In making its award, the AAP cited Prof Meyle’s academic record, noting that he has contributed to five joint consensus papers from the EFP and the AAP, and co-authored a 2008 consensus report on peri-implant diseases that has been cited more than 450 times.
It also mentioned his contribution as a member of the editorial boards of the Journal of Periodontology, the Journal of Periodontal Research, and the EFP’s Journal of Clinical Periodontology.
Prof Meyle, a two-term past president of German periodontology society DG Paro, started his international career as a researcher in periodontology and oral biology with a paper, published in the Archives of Oral Biology in 1990, which assessed for the first time the concentration of ascorbic acid in gingival crevicular fluid. In 1993, his paper on elevated TNF-alpha concentrations in patients with severe periodontitis was published in the Journal of Periodontal Research.
As well as clinical studies on regenerative therapy and implant therapy in periodontitis patients, over the last 15 years his research group has focused on the establishment of an in vitro system for the simulation of the mucosal barrier, which uses oral keratinocytes.
“Within this project, human gingival keratinocytes were immortalised by viral transfection and several cell lines were established and are still the base of many experiments,” Meyle explained.
The research group recently discovered the immunosuppressive action of Porphyromonas gingivalis (Pg) proteins in oral squamous cell carcinoma cancer cells. This new line of research has led to the discovery of T-cell apoptosis and T-reg differentiation by infected tumour cells suggesting that Pg infection is supporting the establishment of an immunosuppressive environment around oral carcinomas.
