Paternal Circadian Disruption Impairs Offspring Cognition via Sperm microRNAs

open access: yesAdvanced Science, EarlyView.
Paternal circadian disruption remodels the sperm small RNA payload, elevating miR‐92a‐3p/miR‐25‐3p levels and perturbing early embryonic gene regulatory programs. Microinjection experiments and single‐embryo transcriptomics reveal sex‐specific developmental vulnerabilities, ultimately impairing offspring hippocampal synaptic plasticity and cognition ...

Regional response to light illuminance across the human hypothalamus

open access: yeseLife
Light exerts multiple non-image-forming biological effects on physiology including the stimulation of alertness and cognition. However, the subcortical circuitry underlying the stimulating impact of light is not established in humans.

Gut microbiota and metabolites in estrus cycle and their changes in a menopausal transition rat model with typical neuroendocrine aging

open access: yesFrontiers in Endocrinology, 2023
BackgroundNeuroendocrine alterations in the mid-life hypothalamus coupled with reproductive decline herald the initiation of menopausal transition. The certain feature and contribution of gut microflora and metabolites to neuroendocrine changes in the ...

Activation of the hypothalamus characterizes the response to acupuncture stimulation in heroin addicts [PDF]

open access: yes, 2007
Acupuncture stimulation elicited a composite of sensations termed deqi that is related to clinical efficacy. Neurobiological studies have identified the hypothalamus as an important component in mediating the deqi.

Adipocyte‐Derived Leptolin Enhances Energy Expenditure and Prevents Obesity

open access: yesAdvanced Science, EarlyView.
We identified a novel adipokine, which we named leptolin. In humans, leptolin levels in white adipose tissue were positively correlated with exercise and negatively associated with body mass index. We observed elevated leptolin in serum from athletes and lower leptolin in serum from obese individuals.

Mouse Microglial Calcitonin Receptor Knockout Impairs Hypothalamic Amylin Neuronal pSTAT3 Signaling but Lacks Major Metabolic Consequences

open access: yesMetabolites, 2022
Amylin and leptin synergistically interact in the arcuate nucleus of the hypothalamus (ARC) to control energy homeostasis. Our previous rodent studies suggested that amylin-induced interleukin-6 release from hypothalamic microglia may modulate leptin ...

The orexigenic effect of ghrelin is mediated through central activation of the endogenous cannabinoid system

open access: yes, 2008
INTRODUCTION: Ghrelin and cannabinoids stimulate appetite, this effect possibly being mediated by the activation of hypothalamic AMP-activated protein kinase (AMPK), a key enzyme in appetite and metabolism regulation. The cannabinoid receptor type 1 (CB1)

Characterising and classifying hypothalamus development [PDF]

open access: yes, 2022
Understanding the development of the hypothalamus is important, due to its role as the central regulator of homeostasis. However, relative to development of other regions of the brain, characterisation and understanding of hypothalamus development is ...

Fibronectin1‐Expressing Subicular Circuits Selectively Govern the Retrieval of Novel Object Recognition

open access: yesAdvanced Science, EarlyView.
Fibronectin 1 (FN1)‐expressing subicular subpopulations encode novel object preference and selectively govern retrieval of novel object recognition (NOR) via affecting excitability of entorhinal‐projecting circuit through large conductance Ca2+‐activated potassium (BK) channel. ABSTRACT Novel object recognition (NOR), referring to the cognitive ability

Volumetric assessment of hypothalamus in relapsing–remitting multiple sclerosis

open access: yesThe Egyptian Journal of Radiology and Nuclear Medicine
Background Multiple sclerosis is the most common neurodegenerative disorder worldwide. Autonomic manifestations are commonly reported in multiple sclerosis patients including sleep disturbance, depressive episodes, chronic fatigue, weight changes and ...
