Different types of potassium transport linked to carbachol and γ-aminobutyric acid actions in rat sympathetic neurons [PDF]

open access: yes, 1984
Carbachol and γ-aminobutyric acid depolarize mammalian sympathetic neurons and increase the free extracellular K+-concentration. We have used double-barrelled ion-sensitive microelectrodes to determine changes of the membrane potential and of the free ...

Chronic Stress Promotes Gastric Cancer Metastasis by Inducing Microbiota‐Associated Kynurenine Accumulation and Macrophage Remodeling

open access: yesAdvanced Science, EarlyView.
Chronic stress reshapes the gut microbiota and enriches Lactobacillus reuteri, promoting microbiota‐associated kynurenine accumulation through altered tryptophan metabolism. Kynurenine drives immunosuppressive remodeling of tumor‐associated macrophages through TNFR2–C/EBPβ signaling, thereby enhancing gastric cancer dissemination.

Chinese Expert Consensus on the Clinical Application of Finerenone in Geriatric Comorbidities

open access: yesAGING MEDICINE, EarlyView.
Mineralocorticoid receptor (MR) overactivation drives inflammation, oxidative stress, and fibrosis in the heart, kidneys, and vasculature, leading to cardiorenal dysfunction. MR signaling promotes hypertrophy, remodeling, and injury through pathways like oxidative stress and inflammation, resulting in vascular stiffness and progressive organ damage ...

Sympathetic modulation of hindlimb muscle contractility is altered in aged rats

open access: yesScientific Reports, 2023
It has recently been demonstrated that reflex excitation of muscle sympathetic nerves triggered by muscle contraction contributes to the maintenance of tetanic force (TF) in rat hindlimb muscles.

The liver‐brain axis: A multidimensional regulatory network implicated in Alzheimer's disease pathogenesis and clinical implications

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Schematic diagram of the core pathways of the liver‐brain axis in regulating AD. The liver regulates cerebral Aβ deposition, tau phosphorylation, and neuroinflammation through pathways such as metabolic detoxification (urea cycle, ketone body metabolism, glutathione antioxidant system), molecular secretion (APOE, CRP, FGF21, IGF‐1), and Aβ clearance ...

Do stretch sensors expressed by aortic baroreceptors interact with circulating estradiol to mediate baroreflex sensitivity in hypertension?

open access: yesFrontiers in Neuroscience
Hypertension, or high blood pressure, is a major risk factor for cardiovascular disease, the leading cause of mortality worldwide. The incidence and the severity of hypertension is higher in middle-aged men than women.

Reframing the Gut–Brain Axis: The Gut Wall as a Neural Immune Interface in Multiple Sclerosis and Autoimmune Neurological Diseases

open access: yesAnnals of Neurology, EarlyView.
Gut wall physiology in multiple sclerosis (MS) and autoimmune neurologic diseases remains underexplored but may span gut barrier dysfunction, enteric glial targeting, mucosal immune dysregulation, and autoimmune targets within the enteric nervous system (ENS).

Contemporary management of pain in cirrhosis: Toward precision therapy for pain

open access: yesHepatology, EarlyView., 2022
Abstract Chronic pain is highly prevalent in patients with cirrhosis and is associated with poor health‐related quality of life and poor functional status. However, there is limited guidance on appropriate pain management in this population, and pharmacologic treatment can be harmful, leading to adverse outcomes, such as gastrointestinal bleeding ...

Local sympathetic nerve depletion does not alter vitiligo progression in a mouse model

open access: yesFrontiers in Medicine
Vitiligo, an autoimmune skin disorder characterized by melanocyte loss, has long been associated with sympathetic nervous system activity. Clinical observations have suggested links between psychological stress, sympathetic activation, and vitiligo ...

A critical reappraisal of the carotid sinus and carotid bulb: Distinguishing neurohistological function from vascular geometry

open access: yesThe Anatomical Record, EarlyView.
This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...
