Diagnostic performance and clinical impacts of metagenomic sequencing after allogeneic hematopoietic stem cell transplantation.

Background: Metagenomic Next-Generation Sequencing (mNGS) is a rapid, non-culture-based, high-throughput technique for pathogen diagnosis. Despite its numerous advantages, only a few studies have investigated its use in patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT).

Methods: We conducted a retrospective analysis of 404 mNGS tests performed on 264 patients after allo-HSCT.

MiR-21-3p in extracellular vesicles from vascular fibroblasts of spontaneously hypertensive rat promotes proliferation and migration of vascular smooth muscle cells.

Enhanced proliferation and migration of vascular smooth muscle cells (VSMCs) contributes to vascular remodeling in hypertension. Adventitial fibroblasts (AFs)-derived extracellular vesicles (EVs) modulate vascular remodeling in spontaneously hypertensive rat (SHR). This study shows the important roles of EVs-mediated miR-21-3p transfer in VSMC proliferation and migration and underlying mechanisms in SHR.

Background: Lamb-Shaffer syndrome (LAMSHF, MIM 616,803) is a rare neurodevelopmental disorder due to haploinsufficiency of SOX5. Furthermore, studies about the clinical features of LAMSHF patients with same allele of c.1477C > T (p.

Dexmedetomidine Attenuates Lipopolysaccharide-Induced Sympathetic Activation and Sepsis via Suppressing Superoxide Signaling in Paraventricular Nucleus.

Sympathetic overactivity contributes to the pathogenesis of sepsis. The selective α2-adrenergic receptor agonist dexmedetomidine (DEX) is widely used for perioperative sedation and analgesia. We aimed to determine the central roles and mechanisms of DEX in attenuating sympathetic activity and inflammation in sepsis.

Cardiomyocyte-specific Peli1 contributes to the pressure overload-induced cardiac fibrosis through miR-494-3p-dependent exosomal communication.

Cardiac fibrosis is an essential pathological process in pressure overload (PO)-induced heart failure. Recently, myocyte-fibroblast communication is proven to be critical in heart failure, in which, pathological growth of cardiomyocytes (CMs) may promote fibrosis via miRNAs-containing exosomes (Exos). Peli1 regulates the activation of NF-κB and AP-1, which has been demonstrated to engage in miRNA transcription in cardiomyocytes.

Chemerin-9 in paraventricular nucleus increases sympathetic outflow and blood pressure via glutamate receptor-mediated ROS generation.

Chemerin is an adipokine involved in regulating energy homeostasis and reproductive function. Excessive sympathetic activity contributes to hypertension, chronic heart failure and chronic renal disease. Hypothalamic paraventricular nucleus (PVN) is crucial in regulating sympathetic activity and blood pressure.

Asprosin in the Paraventricular Nucleus Induces Sympathetic Activation and Pressor Responses via cAMP-Dependent ROS Production.

Asprosin is a newly discovered adipokine that is involved in regulating metabolism. Sympathetic overactivity contributes to the pathogenesis of several cardiovascular diseases. The paraventricular nucleus (PVN) of the hypothalamus plays a crucial role in the regulation of sympathetic outflow and blood pressure.

Angiotensin II-induced miR-31-5p upregulation promotes vascular smooth muscle cell proliferation and migration.

Angiotensin II (Ang II) plays a central role in vascular smooth muscle cell (VSMC) proliferation and migration, being key to regulate vascular function and promote vascular remodeling in cardiovascular diseases. We recently showed that miR-31-5p promoted oxidative stress in spontaneously hypertensive rats. In this study, we aim to investigate whether miR-31-5p and fibronectin type III domain-containing 5 (FNDC5) contribute to Ang II-induced VSMC proliferation and migration.

Norepinephrine acting on adventitial fibroblasts stimulates vascular smooth muscle cell proliferation via promoting small extracellular vesicle release.

Excessive sympathetic activity and norepinephrine (NE) release play crucial roles in the pathogeneses of hypertension. Sympathetic fibers innervate adventitia rather than media of arteries. However, the roles of NE in adventitial fibroblasts (AFs) are unknown.

Impact of Selective Renal Afferent Denervation on Oxidative Stress and Vascular Remodeling in Spontaneously Hypertensive Rats.

Oxidative stress and sustained sympathetic over-activity contribute to the pathogenesis of hypertension.
