Caffeine and Alzheimer's disease
نویسندگان
چکیده
Caffeine is the most commonly used unregulated psychoactive substance used in the world. Up to 90% of North Americans report to use caffeine on a daily basis [1]. Common natural sources include the Coffee plant, Tea plants, Yerba Mate and Kola Nut. It is a white crystalline xanthine alkaloid which generally acts as a stimulant in human physiology. Caffeine is classified as “GRAS” by the US FDA (Generally Recognized as Safe) [2] although there is considerable recent controversy regarding the safety of caffeine addition to alcoholic beverages [3].

Caffeine suppresses amyloid-beta levels in plasma and brain of Alzheimer's disease transgenic mice.
Recent epidemiologic studies suggest that caffeine may be protective against Alzheimer's disease (AD). Supportive of this premise, our previous studies have shown that moderate caffeine administration protects/restores cognitive function and suppresses brain amyloid-beta (Abeta) production in AD transgenic mice. In the present study, we report that acute caffeine administration to both young ad...
متن کاملCaffeine and adenosine.
Caffeine causes most of its biological effects via antagonizing all types of adenosine receptors (ARs): A1, A2A, A3, and A2B and, as does adenosine, exerts effects on neurons and glial cells of all brain areas. In consequence, caffeine, when acting as an AR antagonist, is doing the opposite of activation of adenosine receptors due to removal of endogenous adenosinergic tonus. Besides AR antagon...
متن کاملCaffeine reverses cognitive impairment and decreases brain amyloid-beta levels in aged Alzheimer's disease mice.
We have recently shown that Alzheimer's disease (AD) transgenic mice given a moderate level of caffeine intake (the human equivalent of 5 cups of coffee per day) are protected from development of otherwise certain cognitive impairment and have decreased hippocampal amyloid-beta (Abeta) levels due to suppression of both beta-secretase (BACE1) and presenilin 1 (PS1)/gamma-secretase expression. To...
متن کاملCaffeine and coffee as therapeutics against Alzheimer's disease.
Epidemiologic studies have increasingly suggested that caffeine/coffee could be an effective therapeutic against Alzheimer's disease (AD). We have utilized a transgenic mouse model for AD in well-controlled studies to determine if caffeine and/or coffee have beneficial actions to protect against or reverse AD-like cognitive impairment and AD pathology. AD mice given caffeine in their drinking w...
متن کاملCaffeine protects against disruptions of the blood-brain barrier in animal models of Alzheimer's and Parkinson's diseases.
Sporadic Alzheimer's disease (AD) and Parkinson's disease (PD) are two of the most common neurodegenerative diseases and as such they represent major public health problems. Finding effective treatments for AD and PD represents an unmet and elusive goal largely because these diseases are chronic and progressive, and have a complicated and ill-understood pathogenesis. Although the underlying mec...
