Oral microbiota and Alzheimer's disease: Do all roads lead to Rome?

Alzheimer's disease (AD) is a progressive neurodegenerative pathology affecting milions of people worldwide associated with deposition of senile plaques. While the genetic and environmental risk factors associated with the onset and consolidation of late onset AD are heterogeneous and sporadic, growing evidence also suggests a potential link between some infectious diseases caused by oral microbiota and AD. Oral microbiota dysbiosis is purported to contribute either directly to amyloid protein production, o...

Several Roads Lead to Rome: Operationalizing Antibiotic Stewardship Programs in Nursing Homes.

Trends and Predictors of Oral Anticoagulant Use in People with Alzheimer's Disease and the General Population in Australia.

People with Alzheimer's disease (AD) are less likely to use oral anticoagulants than people without AD.

Time to test antibacterial therapy in Alzheimer's disease.

Alzheimer's disease is associated with cerebral accumulation of amyloid-β peptide and hyperphosphorylated tau. In the past 28 years, huge efforts have been made in attempting to treat the disease by reducing brain accumulation of amyloid-β in patients with Alzheimer's disease, with no success. While anti-amyloid-β therapies continue to be tested in prodromal patients with Alzheimer's disease and in subjects at risk of developing Alzheimer's disease, there is an urgent need to provide therapeutic support ...

Can Oral Health and Oral-derived Biospecimens Predict Progression of Dementia?

Growing evidence indicates that oral health and brain health are interconnected. Declining cognition and dementia coincide with lack of self-preservation, including oral hygiene. The oral microbiota plays an important role in maintaining oral health. Emerging evidence suggests a link between oral dysbiosis and cognitive decline in patients with Alzheimer's disease. This review showcases the recent advances connecting oral health and cognitive function during aging and the potential utility of oral-derived b...

Monocyte Mobilisation, Microbiota & Mental Illness.

The gastrointestinal microbiome has emerged as a key player in regulating brain and behaviour. This has led to the strategy of targeting the gut microbiota to ameliorate disorders of the central nervous system. Understanding the underlying signalling pathways in which the microbiota impacts these disorders is crucial for the development of future therapeutics for improving CNS functionality. One of the major pathways through which the microbiota influences the brain is the immune system, where there is an i...

Oral microbiota and autism spectrum disorder (ASD).

Autism spectrum disorder (ASD) is associated with several oropharyngeal abnormalities, including dysbiosis in the oral microbiota. Since the oral cavity is the start of the gastrointestinal tract, this strengthens and extends the notion of a microbial gut-brain axis in ASD and even raises the question whether a microbial oral-brain axis exists. It is clear that oral bacteria can find their way to the brain through a number of pathways following routine dental procedures. A connection between the oral microb...

Effect of Clostridium Butyricum Against Microglia-Mediated Neuroinflammation in Alzheimer's Disease Via Regulating gut Microbiota and Metabolites Butyrate.

Recent evidences demonstrated that abnormal gut microbiota (GM) might be involved in the pathogenesis of Alzheimer's disease (AD). However, the role of probiotics in preventing AD by regulating GM-gut-brain axis remain unclear. Here, we investigated the anti-neuroinflammatory effect and its mechanism of probiotic Clostridium butyricum (CB) against AD by regulating GM-gut-brain axis.

Signatures of oral microbiome in HIV-infected individuals with oral Kaposi's sarcoma and cell-associated KSHV DNA.

Infection by Kaposi's sarcoma-associated herpesvirus (KSHV) is necessary for the development of Kaposi's sarcoma (KS), which most often develops in HIV-infected individuals. KS frequently has oral manifestations and KSHV DNA can be detected in oral cells. Numerous types of cancer are associated with the alteration of microbiome including bacteria and virus. We hypothesize that oral bacterial microbiota affects or is affected by oral KS and the presence of oral cell-associated KSHV DNA. In this study, oral a...

Environmental Lead Exposure Aggravates the Progression of Alzheimer's Disease in Mice by Targeting on Blood Brain Barrier.

Alzheimer's disease (AD) is a neurodegenerative disease that can be induced by heavy metals such as lead. However, there is limited information on the role of blood-brain barrier (BBB) in lead induced AD-like pathology. This study investigates the potential mechanism of lead exposure aggravating the progression of Alzheimer's disease in mice through the BBB. 200 mg/L and 500 mg/L lead acetate were given to C57BL/6 J and APP/PS1 mice through drinking water from a week before mating, until the offspring...

Interaction between APOE4 and herpes simplex virus type 1 in Alzheimer's disease.

Numerous results suggest the implication of infectious agents in the onset of Alzheimer's disease (AD).

Oral Monosodium Glutamate Administration Causes Early Onset of Alzheimer's Disease-Like Pathophysiology in APP/PS1 Mice.

Glutamate excitotoxicity has long been related to Alzheimer's disease (AD) pathophysiology, and it has been shown to affect the major AD-related hallmarks, amyloid-β peptide (Aβ) accumulation and tau phosphorylation (p-tau). We investigated whether oral administration of monosodium glutamate (MSG) has effects in a murine model of AD, the double transgenic mice APP/PS1. We found that AD pathogenic factors appear earlier in APP/PS1 when supplemented with MSG, while wildtype mice were essentially not affecte...

Exercise, diet and stress as modulators of gut microbiota: Implications for neurodegenerative diseases.

The last decade has witnessed an exponentially growing interest in gut microbiota and the gut-brain axis in health and disease. Accumulating evidence from preclinical and clinical research indicate that gut microbiota, and their associated microbiomes, may influence pathogenic processes and thus the onset and progression of various diseases, including neurological and psychiatric disorders. In fact, gut dysbiosis (microbiota dysregulation) has been associated with a range of neurodegenerative diseases, incl...

Treatment-Specific Composition of the Gut Microbiota Is Associated With Disease Remission in a Pediatric Crohn's Disease Cohort.

The beneficial effects of antibiotics in Crohn's disease (CD) depend in part on the gut microbiota but are inadequately understood. We investigated the impact of metronidazole (MET) and metronidazole plus azithromycin (MET+AZ) on the microbiota in pediatric CD and the use of microbiota features as classifiers or predictors of disease remission.

Computational identification of key genes that may regulate gene expression reprogramming in Alzheimer's patients.

The dementia epidemic is likely to expand worldwide as the aging population continues to grow. A better understanding of the molecular mechanisms that lead to dementia is expected to reveal potentially modifiable risk factors that could contribute to the development of prevention strategies. Alzheimer's disease is the most prevalent form of dementia. Currently we only partially understand some of the pathophysiological mechanisms that lead to development of the disease in aging individuals. In this study, S...

Analysis of Postprandial Symptom Patterns in Subgroups of Patients With Rome III or Rome IV Functional Dyspepsia.

Among patients with functional dyspepsia (FD), there is overlap in symptoms between those in the Rome III subgroups of postprandial distress syndrome (PDS) and those with epigastric pain syndrome (EPS). The Rome IV consensus proposed to incorporate all patients with postprandial symptoms into the PDS group. We aimed to evaluate the assessment of meal-related dyspepsia symptoms in patients with FD according to the Rome III vs Rome IV subdivisions.

Cigarette smoking and oral microbiota in low-income and African-American populations.

Cigarette smoking is a common risk factor for diseases and cancers. Oral microbiota is also associated with diseases and cancers. However, little is known about the impact of cigarette smoking on the oral microbiota, especially among ethnic minority populations.

miR-16-5p and miR-19b-3p prevent amyloid β-induced injury by targeting BACE1 in SH-SY5Y cells.

Alzheimer's disease is the most common neurodegenerative disease, characterized by accumulation of amyloid β peptides. MicroRNAs have been identified as significant regulators and therapeutic targets of Alzheimer's disease. However, the roles of miR-16-5p and miR-19b-3p and their mechanisms in Alzheimer's disease progression remain largely unknown.

Tau Aggregation Correlates with Amyloid Deposition in Both Mild Cognitive Impairment and Alzheimer's Disease Subjects.

Amyloid plaque and tau-containing neurofibrillary tangles are important features of Alzheimer's disease (AD). However, the relationship between these processes is still debated.

A pilot study of exenatide actions in Alzheimer's disease.

Strong preclinical evidence suggests that exenatide, a glucagon-like peptide-1 (GLP-1) receptor agonist used for treating type 2 diabetes, is neuroprotective and disease- modifying in Alzheimer's disease (AD).

"Like He's a Kid": Relationality, Family Caregiving, and Alzheimer's Disease.

Spousal caregivers draw upon understandings of shifting relationality to maintain a familial understanding of their spouse with Alzheimer's disease. Working through what it means to think of an adult with Alzheimer's disease "like a child," I trace how spouses negotiate their shifting relationships across the course of Alzheimer's. While regarding adults as childlike can be perceived as dehumanizing infantilization, for families living with Alzheimer's disease, conceiving of one's spouse as like a child can...

Examining the link between dose-dependent dietary iron intake and Alzheimer's disease through oxidative stress in the rat cortex.

Neurodegenerative diseases such as Alzheimer's and Parkinson's disease are characterized by the progressive deterioration of the structure and function of the nervous system. A number of environmental risk factors including potentially toxic elements such as iron, lead to negative effects on many metabolic reactions as well as neuroprotection. The aim of this study is to reveal whether long-term iron overload is one of the underlying factors in the pathogenesis of Alzheimer's disease (AD).

Cognitive Decline and Alzheimer's Disease in Old Age: A Sex-Specific "Cytokinome Signature".

Elevated peripheral levels of different cytokines and chemokines in subjects with Alzheimer's disease (AD), as compared with healthy controls (HC), have emphasized the role of inflammation in such a disease. Considering the cross-talking between the central nervous system and the periphery, the inflammatory analytes may provide utility as biomarkers to identify AD at earlier stages.

The Prevention of Infections in Older Adults: Oral Health.

The oral cavity is exposed to the external environment and from a very young age is colonized by infectious agents. Under certain circumstances including poor oral hygiene, dry mouth, trauma, and the use of antibiotics, oral infections can occur. They can result in damage to the oral cavity including teeth and their support structures. Oral infections can also lead to the extension of infection into surrounding tissues and to systemic infections. Chronic oral infection is a recognized risk factor for heart ...
