Kim P, Garner N, Tatkovic A, Parsons R, Chunduri P, Vukovic J, et al.
NPJ Biol Timing Sleep . 2024 Nov; 1(1):13. PMID: 39493889
Melatonin supplementation strengthens non-restorative sleep rhythms and its temporal alignment in both humans and night-active rodents. Of note, although the sleep cycle is reversed in day-active and night-active (nocturnal) mammals,...

von Gall C, Holub L, Pfeffer M, Eickhoff S
Brain Sci . 2023 Oct; 13(10). PMID: 37891848
In modern society, the time and duration of sleep on workdays are primarily determined by external factors, e.g., the alarm clock. This can lead to a misalignment of the intrinsically...

Pfeffer M, von Gall C, Wicht H, Korf H
Front Physiol . 2022 May; 13:883637. PMID: 35492605
The melatoninergic system comprises the neurohormone melatonin and its molecular targets. The major source of melatonin is the pineal organ where melatonin is rhythmically produced during darkness. In mammals, melatonin...

Hassan S, Ali A, Yassine M, Sohn D, Pfeffer M, Janicke R, et al.
J Pineal Res . 2021 Feb; 70(3):e12724. PMID: 33615553
Cancer-related fatigue (CRF) and stress are common symptoms in cancer patients and represent early side effects of cancer treatment which affect the life quality of the patients. CRF may partly...

Ali A, Tundo-Lavalle F, Hassan S, Pfeffer M, Stahr A, von Gall C
Int J Mol Sci . 2020 Feb; 21(4). PMID: 32092990
The circadian system is an endogenous timekeeping system that synchronizes physiology and behavior with the 24 h solar day. Mice with total deletion of the core circadian clock gene Bmal1...

Metzger J, Wicht H, Korf H, Pfeffer M
J Biol Rhythms . 2019 Oct; 35(1):58-71. PMID: 31625428
Locomotor activity patterns of laboratory mice are widely used to analyze circadian mechanisms, but most investigations have been performed under standardized laboratory conditions. Outdoors, animals are exposed to daily changes...

Stenzinger M, Karpova D, Unterrainer C, Harenkamp S, Wiercinska E, Hoerster K, et al.
Cells . 2019 Sep; 8(9). PMID: 31491915
Circadian oscillations in circulating leukocyte subsets including immature hematopoietic cells have been appreciated; the origin and nature of these alterations remain elusive. Our analysis of wild-type C57BL/6 mice under constant...

Brunkhorst R, Pfeilschifter W, Rajkovic N, Pfeffer M, Fischer C, Korf H, et al.
Biochim Biophys Acta Mol Cell Biol Lipids . 2018 Dec; 1864(3):304-311. PMID: 30557628
Key homeostatic functions are regulated in a diurnal manner and a miss-alignment of such rhythms is believed to contribute to the pathophysiology of several diseases. Signaling sphingolipids (SLs) in plasma...

Pfeffer M, Zimmermann Z, Gispert S, Auburger G, Korf H, von Gall C
Int J Mol Sci . 2018 Jun; 19(6). PMID: 29865270
Parkinson's disease (PD) is characterized by distinct motor and non-motor symptoms. Sleep disorders are the most frequent and challenging non-motor symptoms in PD patients, and there is growing evidence that...

Pfeffer M, Korf H, Wicht H
Gen Comp Endocrinol . 2017 May; 258:215-221. PMID: 28533170
In mammals, the rhythmic secretion of melatonin from the pineal gland is driven by the circadian clock in the suprachiasmatic nucleus (SCN) of the hypothalamus. The robust nightly peak of...
