Activation of Spinal Astrocyte α2A Adrenoceptors Protects Against Sepsis‐Induced Heart Injury Through Inhibition of GABAergic Neuronal Necroptosis

open access: yesAdvanced Science, EarlyView.
The study in this paper found that activating the α2A receptors of astrocytes in the thoracic spinal cord can reduce the release of inflammatory factors, thereby decreasing the necroptosis of GABAergic neurons and consequently alleviating myocardial injury caused by sepsis.

Assessments of Heart Rate and Sympathetic and Parasympathetic Nervous Activities of Normal Mouse Fetuses at Different Stages of Fetal Development Using Fetal Electrocardiography

open access: yesFrontiers in Physiology, 2021
Heart rate is controlled by the activity of the autonomic nervous system: the sympathetic and parasympathetic nervous systems increase and suppress heart rate, respectively.

Sympathetic Activation Promotes Kidney Fibrosis in Mice via Macrophage‐Derived N2ICD‐Enriched Extracellular Vesicles

open access: yesAdvanced Science, EarlyView.
Norepinephrine/α2B‐adrenoceptor axis promotes the secretion of Notch2 intracellular domain (N2ICD)‐enriched extracellular vesicles (EVs) from macrophages. These EVs deliver N2ICD into fibroblasts, thereby inducing their activation. Deletion of Notch2 or α2B‐AR in macrophages disrupts N2ICD‐enriched EV formation and alleviates kidney fibrosis in mice ...

Norepinephrine Induces Sertoli Cell Ferroptosis via Receptors Desensitization Causing Stress‐Related Male Reproductive Dysfunction

open access: yesAdvanced Science, EarlyView.
Psychological stress activates the sympathetic–adrenal axis, elevating norepinephrine (NE) and suppressing reproductive hormones, thereby impairing male reproduction. Excess NE overactivates and desensitizes β‐adrenergic receptors (β‐ARs), triggering Sertoli cell ferroptosis and disrupting spermatogenesis.

Distribution of α7 Nicotinic Acetylcholine Receptor Subunit mRNA in the Developing Mouse. [PDF]

open access: yes, 2019
Homomeric α7 nicotinic acetylcholine receptors (nAChRs) are abundantly expressed in the central and peripheral nervous system (CNS and PNS, respectively), and spinal cord.

Nociceptive Nerve‐Derived CGRP Exacerbates Uterine Fibrogenesis in Adenomyosis by Promoting CD140b+ CD146+ Fibroblast Differentiation

open access: yesAdvanced Science, EarlyView.
This study investigates adenomyosis fibrosis in relation to nociceptive nerves. Nociceptive nerve‐secreted CGRP promotes RAMP1hi CD140b+ CD146+ fibroblast differentiation into myofibroblasts through ERK activation, causing severe fibrosis. Rimegepant‐induced CGRP/RAMP1 signaling blockade alleviates fibrosis and restores fertility in a mouse model. This

Oxidative Stress in the Brain Causes Hypertension via Sympathoexcitation

open access: yesFrontiers in Physiology, 2012
Activation of the sympathetic nervous system has an important role in the pathogenesis of hypertension, and is determined by the brain. Previous many studies have demonstrated that oxidative stress, mainly produced by angiotensin II type 1 (AT1) receptor

Photoplethysmography for Quantitative Assessment of Sympathetic Nerve Activity (SNA) During Cold Stress [PDF]

open access: yes, 2019
The differences in the degree of sympathetic nerve activity (SNA) over cutaneous blood vessels, although known to be more prominent in the periphery than the core vasculature, has not been thoroughly investigated quantitatively.

Targeting Histamine H4 Receptor in the Rostral Ventromedial Medulla to Relieve Hypertension

open access: yesAdvanced Science, EarlyView.
H4R and its downstream TRPV1 channel mediate the excitatory effect of TMN histaminergic afferent inputs on GABAergic sympathoinhibitory neurons in RVMM. Intranasal delivery of selective H4R agonist VUF 8430 suppresses renal sympathetic outflow and elicits sustained depressor and bradycardia responses in SHRs and CUMS‐induced hypertensive rats ...
