Abstract
The 2nd International Conference on Oral Mucosal Immunity and the Microbiome (OMIM) took place at the Grecotel Kos Imperial Hotel, Kos, Greece, between 25th and 30th September 2021, under the auspices of the Aegean Conferences. This has only been the second Aegean Conference of this thematic, the first one having taken place in 2018 in Crete, during the same period of the year. Given the hardships in travel and heightened infection transmission risks amid the COVID-19 pandemic, the Conference was well attended by 29 international speakers across the world. For many of the participants, this was the first conference travel in the post-pandemic era, and quite significant that it has taken place on the island of Hippocrates. Stringent regional health and safety regulations had to be followed to accomplish for this in-person Conference to take place. Frontiers in Oral Health has hosted papers from presentations of the Conference, whereas the present article serves as the proceedings of the Conference with summaries of the presentations.

Richard Lamont addressed the multidimensional and context-dependent interactions between Porphyromonas gingivalis and Streptococcus gordonii which can occur through several mechanisms: (i) chemical communication, mediated by the streptococcal metabolite para-aminobenzoic acid, which can dampen the pathogenic potential of P. gingivalis by regulating gingipain production; (ii) in contrast, direct contact interactions between the two organisms can increase the pathogenic potential of the community via a tyrosine phosphorylation/dephosphorylation signaling cascade; (iii) S. gordonii can modulate the impact of P. gingivalis on epithelial cells using the host cell as an intermediary
This high conservation in gene expression between periodontitis and logarithmic laboratory growth is driven by overall low variance in P. gingivalis gene expression, relative to other pathogens including Pseudomonas aeruginosa and Staphylococcus aureus
