Network-level time computations in the suprachiasmatic nucleus. [PDF]

open access: yesCell Res
Deciphering neuronal circuit dynamics is critical for understanding how the brain encodes information. In a recent study in Cell Research, Wang et al.

Neurotrophic Signaling, Sleep Physiology, and Retinal Neuroprotection: Integrative Mechanisms and Therapeutic Implications for Glaucoma

open access: yesSensory Neuroscience, EarlyView.
Glaucoma is increasingly understood as a neurodegenerative disorder shaped by sleep and circadian physiology, not intraocular pressure alone. Sleep loss and obstructive sleep apnea suppress BDNF–TrkB neurotrophic signaling, impair sleep‐dependent glymphatic clearance, and trigger microglial neuroinflammation and vascular insult at the optic nerve head,

Cholecystokinin receptor type A are involved in the circadian rhythm of the mouse retina

open access: yesHeliyon
The retina is the only organ projecting external light to the suprachiasmatic nucleus. Cholecystokinin receptor type A (Cckar/Cckar) is one of the essential factors for light reception in retinal cells. As there was a lack of literature on the matter, we

NMDA receptor subunit‐dependent analysis of radiprodil inhibition in neonatal male rat substantia nigra dopaminergic neurons

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Radiprodil is a GluN2B subunit selective NMDA receptor negative allosteric modulator which is currently under clinical investigation as a possible anti‐epileptic drug for paediatric use. Our goal was to investigate the inhibition of dopaminergic neuron NMDA responses by radiprodil.

A hypothetic aging pathway from skin to hypothalamic suprachiasmatic nucleus via slow wave sleep

open access: yesSleep Science, 2016
Many observations have demonstrated that the hypothalamic neuroendocrine change determines the chronological sequence of aging in mammals. However, it remains uncertain on the mechanism to account for the hypothalamic aging manifestations.

Therapeutic access points: The roles of circumventricular organs in drug delivery and metabolic regulation

open access: yesBritish Journal of Pharmacology, EarlyView.
The current obesity drug landscape, dominated by GLP‐1 receptor agonists and emerging multi‐agonist therapies, has reinforced that long‐term weight loss is achieved in large part through central mechanisms that suppress appetite and reshape energy balance.

Loss of ZBTB20 impairs circadian output and leads to unimodal behavioral rhythms

open access: yeseLife, 2016
Many animals display morning and evening bimodal activities in the day/night cycle. However, little is known regarding the potential components involved in the regulation of bimodal behavioral rhythms in mammals.

Circadian disruption elicits sex‐specific gut microbiota, endocannabinoidome, and lipid mediator responses

open access: yesThe FEBS Journal, EarlyView.
Circadian disruption via constant light induces sex‐specific remodeling of the microbiome, lipid mediators, and immune responses. Females exhibit broader gut microbiota alterations, reduced jejunal oxylipins, increased hypothalamic N‐acylethanolamines, and a more inflammatory cytokine profile. Muscle responses are sex‐ and fiber type‐dependent: females

Imaging Individual Differences in the Response of the Human Suprachiasmatic Area to Light

open access: yesFrontiers in Neurology, 2018
Circadian disruption is associated with poor health outcomes, including sleep and mood disorders. The suprachiasmatic nucleus (SCN) of the anterior hypothalamus acts as the master biological clock in mammals, regulating circadian rhythms throughout the ...

The VIP-VPAC2 neuropeptidergic axis is a cellular pacemaking hub of the suprachiasmatic nucleus circadian circuit

open access: yesNature Communications, 2020
Circadian activity modulation in the suprachiasmatic nucleus (SCN) is a network-level emergent property that requires neuropeptide VIP signaling, yet the precise cellular mechanisms are unknown. Patton et al.
