Schlaf kann das Gehirn vor Alzheimer, Artherosklerose und Krebs schützen
Zu dieser Erkenntnis kamen Forscher von mehreren Universitäten in USA (holtzman@wustl.edu) im Februar 2019
Darunter eine Liste der neuesten Studien zum Thema Schlafmangel und Krebs und der Hinweis auf eine
Schwedische Studie von 2016 – WEA-Schall und Schlaf
I. Schlaf und Alzheimer – Schlaf kann das Gehirn vor AD schützen
Aus der o.g. Original-Studie:
Der Schlaf-Wach-Zyklus reguliert das interstitielle Flüssigkeits-Tau des Gehirns bei Mäusen und das CSF-Tau beim Menschen
Schlaf kann das Gehirn vor AD schützen
Bei der Alzheimer-Krankheit (AD) reichern sich im Gehirn zwei Hauptproteine an: β-Amyloid (Aβ) und Tau. Aβ scheint AD auszulösen, aber Tau scheint Hirnschäden und kognitiven Verfall zu verursachen. Es ist bekannt, dass Schlafentzug Aβ akut und chronisch erhöht. Nun haben Holth et al. zeigen, dass chronischer Schlafentzug über Stunden hinweg die Tau akut stark erhöht und auch die Ausbreitung der Tau-Pathologie im Gehirn von Mäusen und Menschen fördert (siehe die Perspektive von Noble und Spires-Jones). Daher scheint der Schlaf einen direkten schützenden Effekt auf ein Schlüsselprotein zu haben, das die AD-Pathologie antreibt.
Sleep may protect the brain from AD
Two main proteins accumulate in the brain in Alzheimer’s disease (AD), β-amyloid (Aβ) and tau. Aβ appears to instigate AD, but tau appears to drive brain damage and cognitive decline. Sleep deprivation is known to increase Aβ acutely and chronically. Now, Holth et al. show that chronic sleep deprivation strongly increases tau acutely over hours and also drives tau pathology spreading in the brains of mice and humans (see the Perspective by Noble and Spires-Jones). Thus, sleep appears to have a direct protective effect on a key protein that drives AD pathology.

Hintergrundwissen zum besseren Verständnis:
Wenn Gehirnzellen absterben – Veränderungen im Gehirn
Bei der Alzheimer-Krankheit sterben nach und nach immer mehr Nervenzellen ab. Patienten leiden deshalb an Gedächtnisverlust und Orientierungslosigkeit. Wir erklären, was dabei im Gehirn passiert.
Beta-Amyloid (Aß) ist ein natürlich im Körper vorkommendes Eiweiß, das durch eine biochemische Reaktion aus dem Amyloid-Vorläuferprotein entsteht. Im gesunden Gehirn wird das Eiweiß problemlos gespalten und abgebaut. Bei der Alzheimer-Krankheit verändert sich der Abbau des Amyloid-Vorläuferproteins. Dadurch entstehen sogenannte Beta-Amyloid-Proteine, die sich als giftige Oligomere ansammeln. Diese wiederum verklumpen und bilden die unauflöslichen Ablagerungen zwischen den Nervenzellen, die sogenannten ß-Amyloid-Plaques, auch Alzheimer-Plaque genannt. Diese können nicht mehr vom Körper abgebaut werden.
Das Tau-Protein befindet sich im Inneren der Zelle. Es formt Teile einer Struktur, die man Mikrotubuli (Röhrchen) nennt. Diese Röhrchen helfen beim Transport von Nährstoffen und anderen wichtigen Substanzen von einem Teil der Nervenzelle zu einem anderen. Tau-Proteine sind für die Stabilität und die Nährstoffversorgung der Zellen verantwortlich. Bei der Alzheimer-Erkrankung wird das Tau-Protein chemisch verändert. Dieses veränderte Protein sammelt sich in der Nervenzelle und lagert sich in Form von Fasern an, den sogenannten Tau-Fibrillen. Die Zellen verlieren ihre Form, ihre Funktionen und zerfallen.
Die beiden Eiweißablagerungen stören die Kommunikation in und zwischen den Nervenzellen. Dadurch sterben über viele Jahre hinweg Nervenzellen und Nervenzellverbindungen ab. Betroffen sind die Regionen im Gehirn, die für das Gedächtnis, das Denken, die Sprache und die Orientierung zuständig sind: die Großhirnrinde und der Hippocampus.
Übrigens: Untersuchungen von Gehirnen nach dem Tod haben in Studien gezeigt, dass Tau-Fibrillen in einem engeren Zusammenhang mit den klinischen Symptomen der Alzheimer-Patienten stehen, als senile Plaques.

II. Schlaf und Artherosklerose – Ungestörter Schlaf hält auch die Blutgefäße gesund
Wissenschaft aktuell.de berichtet über die Auswirkungen von gestörtem Schlaf auf die Blutgefäße
Studie aus Boston, USA
So schützt Schlaf vor Arteriosklerose
Von Joachim CzichosBei chronischen Schlafstörungen verursacht der Mangel eines im Hirn gebildeten Hormons, dass im Knochenmark verstärkt weiße Blutkörperchen produziert werden, die Ablagerungen in den Arterien begünstigen
Schlafmangel erhöht das Risiko für Fettleibigkeit, Diabetes, Krebs und Herz-Kreislauferkrankungen.
Wie es dazu kommt, ist noch weitgehend unbekannt. Jetzt haben amerikanische Forscher herausgefunden, dass sich bei chronischen Schlafstörungen die Entwicklung einer Arteriosklerose bei Mäusen beschleunigt. Durch die verringerte Schlafdauer sank die Produktion des Hormons Hypocretin im Gehirn. Das verstärkte die Freisetzung eines Botenstoffs im Knochenmark, wodurch dort vermehrt weiße Blutkörperchen gebildet wurden. Diese hefteten sich dann an den Wänden der Blutgefäße an und bewirkten weitere Ablagerungen, berichten die Wissenschaftler im Fachjournal „Nature“. Eine Behandlung mit Hypocretin normalisierte die Zahl der weißen Blutkörperchen im Blut und senkte das Risiko einer Arteriosklerose.

Wie ungenügender oder unterbrochener Schlaf Menschen für Atherosklerose und die Alzheimer-Krankheit anfällig machen können
HOW INADEQUATE OR FRAGMENTED SLEEP CAN PREDISPOSE PEOPLE TO ATHEROSCLEROSIS AND ALZHEIMER DISEASE
Fast die Hälfte der Erwachsenen in den Vereinigten Staaten schlafen weniger als empfohlen. Unzureichender Schlaf wurde in Verbindung gebracht epidemiologisch für viele Krankheiten, aber eine biologische Basis für diese Krankheitsassoziationen fehlt.
In einer Studie in der Ausgabe vom 21. Februar 2019 von Nature (https://doi.org/10.1038/s41586-019-0948-2), führten Forscher Experimente an für Atherosklerose anfälligen Mäusen durch:
Der Schlaf wurde unterbrochen bzw. nicht unterbrochen.
Unterbrochen Schlaf führte zu einer höheren Anzahl von Monozyten und größeren atherosklerotische Läsionen und auch zur Produktion von weniger Hypocretin (Orexin) im Hypothalamus.
Der niedrigere Produktion von Hypocretin war die Ursache für die höhere Anzahl der Monozyten.
Frühere Studien fanden den Zusammenhang von der Anzahl der zirkulierenden Monozyten (und anderer weißer Zellen) zur Entwicklung von Atherosklerose.
Mechanismus siehe oben.
In einer anderen Studie, zu lesen in der Science-Ausgabe vom 22. Februar 2019* (https://doi.org/10.1126/science.aav2546), haben Forscher gezeigt, dass Schlaf den Spiegel sowohl von Amyloid-β- als auch von Tau-Proteinen (die mit der Alzheimer-Krankheit in Verbindung gebracht werden) im interstitiellen Raum der Gehirne von Mäusen verbraucht.
Dieser Befund bei Mäusen wurde in menschlichen Zerebrospinalflüssigkeit, unter Verwendung von Lumbalkathetern, bestätigt.
Diese beiden Studien decken plausible biologische Mechanismen auf, durch die der Schlaf vor Arteriosklerose und Alzheimer-Krankheit schützt. Die letztere Studie stimmt mit anderen überein, die darauf hingewiesen haben, dass Schlafmangel toxisch wirken (www.jwatch.org/na47351)

Sleep & Cancer – Research by Eric Rosenblum, USA / NAPAW – April 2019
So I thought I’d just do a simple PubMed search:
Researchers have indeed been looking into the issue, primarily it seems for 2 reasons:
- Melatonin is known to be protective against breast cancer, and melatonin production requires quality sleep (also, night shift work is associated with greater risk of breast cancer); and
- sleep plays an important role for immune, cardiovascular, and neurocognitive functions.
The findings are very inconsistent, which isn’t surprising given the myriad potential contributing factors.
Where links have been found, it is /more/ sleep as often as /less/ sleep that is associated with greater risk of cancer. Which suggests to me that /more/ sleep is indicative of lower-quality sleep.
Another sleep-related area of research finds that obstructive sleep apnea (OSA) is associated with greater risk of cancer, which could be due to poor oxygenation as much as to interrupted sleep.
I’ve attached a list of the relevant non-OSA papers from the first 100 results. Many of them are meta-analyses rather than original research.

Sleep and Breathing … and Cancer?
Robert L. Owens, Kathryn A. Gold, David Gozal, et al; UCSD Sleep and Cancer Symposium Group.
[Abstract] Sleep, like eating and breathing, is an essential part of the daily life cycle. Although the science is still emerging, sleep plays an important role in immune, cardiovascular, and neurocognitive function. Despite its great importance, nearly 40% of U.S. adults experience problems with sleep ranging from insufficient total sleep time, trouble initiating or maintaining sleep (Insomnia), circadian rhythm disorders, sleep-related movement disorders, and sleep-related breathing disorders such as obstructive sleep apnea (OSA). Herein, we discuss new evidence that suggests that sleep may also affect carcinogenesis.

Sleep and cancer: Synthesis of experimental data and meta-analyses of cancer incidence among some 1,500,000 study individuals in 13 countries.
Erren TC, Morfeld P, Foster RG, et al.
[Abstract] Sleep and its impact on physiology and pathophysiology are researched at an accelerating pace and from many different angles. Experiments provide evidence for chronobiologically plausible links between chronodisruption and sleep and circadian rhythm disruption (SCRD), on the one hand, and the development of cancer, on the other. Epidemiological evidence from cancer incidence among some 1 500 000 study individuals in 13 countries regarding associations with sleep duration, napping or „poor sleep“ is variable and inconclusive. Combined adjusted relative risks (meta-RRs) for female breast cancer, based on heterogeneous data, were 1.01 (95% CI: 0.97-1.06). Meta-RRs for cancers of the colorectum and of the lung in women and men and for prostate cancer were 1.08 (95% CI: 1.03-1.13), 1.11 (95% CI: 1.00-1.22) and 1.05 (95% CI: 0.83-1.33), respectively. The significantly increased meta-RRs for colorectal cancer, based on homogeneous data, warrant targeted study. However, the paramount epidemiological problem inhibiting valid conclusions about the associations between sleep and cancer is the probable misclassification of the exposures to facets of sleep over time. Regarding the inevitable conclusion that more research is needed to answer How are sleep and cancer linked in humans? we offer eight sets of recommendations for future studies which must take note of the complexity of multidirectional relationships.

Oxidative stress, cancer, and sleep deprivation: is there a logical link in this association?
Noguti J, Andersen ML, Cirelli C, Ribeiro DA.
[Abstract] Discussion: It is a normal process for cellular metabolism to produce reactive oxidant series (ROS). However, when the production of ROS overcomes the antioxidant capacity of the cell to eliminate these products, the resulting state is called oxidative stress. Oxidative DNA damage may participate in ROS-induced carcinogenesis. Moreover, ROS are also produced in the sleep deprivation process. The aim of this article is to review pathways and mechanisms that may point to oxidative stress as a link between sleep deprivation and cancer.
