Chronic periodontitis of 10 years’ duration is reported to become a twofold risk factor for the development of Alzheimer’s disease (AD). 2. Summary: : Gingipains, and key enzyme from Porphyromonas Gingivalis, may play a key role in the pathogenesis of Alzheimer's Disease, and novel inhibitors of gingipains may strengthen this connection. "Despite significant funding and the best efforts of academic, industry, and advocacy communities, clinical progress against Alzheimer's has been frustratingly slow," said Casey Lynch, Cortexyme's co-founder, chief executive officer, and an author on the paper.

The case for P. gingivalis as a major player in Alzheimer’s progression is presented well here, in human brain, CSF, and in P. gingivalis-infected mice, and the authors also show that gingipain inhibitors prevent the pathological changes. Alzheimer’s disease; however, the nature of this association has been unclear. Porphyromonas gingivalis, a major subgingival plaque bacterium in periodontitis, has recently attracted much attention as a possible microbial driver in Alzheimer’s disease.In the present paper, another common neuroinflammatory disease, Parkinson’s disease (PD), is discussed.

Background: Porphyromonas gingivalis (P. gingivalis) and its gingipain virulence factors have been identified as pathogenic effectors in Alzheimer’s disease (AD).In a recent study we demonstrated the presence of gingipains in over 90% of postmortem AD brains, with gingipains localizing to … When Porphyromonas Gingivalis was given to mice it lead to brain infection, amyloid production, tau tangles, and neural damage in regions and nerves typically affected by AD.

Larger trials will launched looking for Porphyromonas Gingivalis in spinal fluid and cognitive improvements, both before and after. Amyloid and tau proteins can accumulate in the brain for 10-20 years before symptoms begin.
