LATEST PROTEIN SPOTLIGHT: A LOOSENING OF HABITS

We are not alone. From the day we are born, we carry with us hordes of microorganisms which, if all is going well, live off us while giving something in return. This micro-universe which is an integral part of our physiology has been called the microbiome.

In the recent years, scientists have demonstrated the importance a microbiome has on our overall health; how it can influence our well-being as it can be at the heart of a disease. Take our mouths for instance. A mouth is home to billions of microorganisms with whom we share our life on a daily basis.

However, when the balance between them and us is perturbed, it can cause discomforts such as periodontal disease, also known as gum disease or periodontitis. Periodontal disease is probably the doing of a variety of microorganisms, but there is one bacterium that seems to have a major role in its development: Porphyromonas gingivalis. P.gingivalis has filaments - or fimbriae - that protrude from its outer membrane and help the bacterium adhere, among other things, to host cells. The molecular structure of fimbriae is gradually emerging, as are the roles of the proteins that are part of it. Read more
