Microbiome-Safe Toothpaste Targets Gum Disease Without Killing Beneficial Bacteria

Researchers have developed a microbiome-friendly toothpaste that uses a targeted compound to inhibit the gum-disease pathogen Porphyromonas gingivalis without disrupting the broader oral microbiome, allowing beneficial bacteria to rebalance the mouth and potentially reduce periodontitis. The approach, developed with PerioTrap and Fraunhofer institutes, also spawns post-cleaning products like a care gel, with ongoing development of additional oral-care solutions.

The Oral-Gut Connection: Exploring the Link Between Infection and Alzheimer's

A growing body of scientific research suggests that Alzheimer's disease may be caused by an infection, with one study linking the pathogen Porphyromonas gingivalis, responsible for gum disease, to the brains of deceased Alzheimer's patients. In experiments with mice, oral infection with the bacteria led to brain colonization and increased production of amyloid beta, a protein associated with Alzheimer's. The researchers also identified toxic enzymes called gingipains secreted by the bacteria in the brains of Alzheimer's patients, even in those who were never diagnosed with the disease. A compound called COR388 showed promise in reducing bacterial load and amyloid-beta production in mice. Further research is needed to fully understand the link between gum disease and Alzheimer's.
