Otakar q StruneckyFluoride has been employed in laboratory investigations since the early 20th century. These studies opened the understanding of fluoride interventions to fundamental biological processes. Millions of people living in endemic fluorosis areas suffer from various pathological disturbances. The practice of community water fluoridation used prophylactically against dental caries increased concern of adverse fluoride effects. We assessed the publications on fluoride toxicity until June 2020. We present evidence that fluoride is an enzymatic poison, inducing oxidative stress, hormonal disruptions, and neurotoxicity. Fluoride in synergy with aluminum acts as a false signal in G protein cascades of hormonal and neuronal regulations in much lower concentrations than fluoride acting alone. Our review shows the impact of fluoride on human health. We suggest focusing the research on fluoride toxicity to the underlying integrative networks. Ignorance of the pluripotent toxic effects of fluoride might contribute to unexpected epidemics in the future.

Otakar q StruneckyThe continuous rise of autism spectrum disorder (ASD) prevalent in the past few decades is causing an increase in public health and socioeconomic concern. A consensus suggests the involvement of both genetic and environmental factors in the ASD etiopathogenesis. Fluoride (F) is rarely recognized among the environmental risk factors of ASD, since the neurotoxic effects of F are not generally accepted. Our review aims to provide evidence of F neurotoxicity. We assess the risk of chronic F exposure in the ASD etiopathology and investigate the role of metabolic and mitochondrial dysfunction, oxidative stress and inflammation, immunoexcitotoxicity, and decreased melatonin levels. These symptoms have been observed both after chronic F exposure as well as in ASD. Moreover, we show that F in synergistic interactions with aluminum’s free metal cation (Al3+) can reinforce the pathological symptoms of ASD. This reinforcement takes place at concentrations several times lower than when acting alone. A high ASD prevalence has been reported from countries with water fluoridation as well as from endemic fluorosis areas. We suggest focusing the ASD prevention on the reduction of the F and Al3+ burdens from daily life.

Otakar q StruneckyOur review suggests that most autism spectrum disorder (ASD) risk factors are connected, either directly or indirectly, to immunoexcitotoxicity. Chronic brain inflammation is known to enhance the sensitivity of glutamate receptors and interfere with glutamate removal from the extraneuronal space, where it can trigger excitotoxicity over a prolonged period. Neuroscience studies have clearly shown that sequential systemic immune stimulation can activate the brain's immune system, microglia, and astrocytes, and that with initial immune stimulation, there occurs CNS microglial priming. Children are exposed to such sequential immune stimulation via a growing number of environmental excitotoxins, vaccines, and persistent viral infections. We demonstrate that fluoride and aluminum (Al3+) can exacerbate the pathological problems by worsening excitotoxicity and inflammation. While Al3+ appears among the key suspicious factors of ASD, fluoride is rarely recognized as a causative culprit. A long-term burden of these ubiquitous toxins has several health effects with a striking resemblance to the symptoms of ASD. In addition, their synergistic action in molecules of aluminofluoride complexes can affect cell signaling, neurodevelopment, and CNS functions at several times lower concentrations than either Al3+ or fluoride acting alone. Our review opens the door to a number of new treatment modes that naturally reduce excitotoxicity and microglial priming.

The discoveries of the pluripotent role of glycogen synthase kinase-3 (GSK-3) are pointing to GSK-3 as a potential target for therapy of neurodegenerative disorders and type 2 diabetes. GSK-3 is a constitutively active protein kinase that is inhibited in response to various extracellular signals. Lithium has been found to be an important inhibitor of GSK-3 activity and its use as a laboratory tool has contributed to the understanding of the role of GSK-3. Fluoride has been often used in study designs on GSK-3 as the inhibitor of protein phosphatases. Potential interactions of fluoride with the observed lithium effects are discussed.

Strunecka has over 30 years´ experience teaching biologists, biochemists, toxicologists, and biophysicists. She is the author of five textbooks. She was the supervisor of 47 gradual students and 15 postgraduate students, and the chairman of the Board for doctoral thesis in physiology.
Her scientific work has been focused on the physiological role of inositol lipids and calcium.
She has urged the health risks of fluoridated drinking water and several food additives. She published 14 scientific-popular books in the Czech, three of them became bestsellers (www.strunecka.cz).
In the years 2002–2003 she was the coordinator of the proposal for grant of the EC EU European Fluoride and Aluminium Network of Excellence (EFANE) to priority Food Quality and Safety. The EFANE consortium consisted of 357 participants from 17 countries. The objective of EFANE was to integrate health risks exposure to fluoride and aluminum from environmental sources.
