Background: Hypertension is a leading risk factor for all-cause mortality worldwide, affecting ≈1.3 billion people. Imbalanced gut microbiota contributes to blood pressure elevation.

Hypertension is characterized by chronic inflammation. Anatabine, a natural alkaloid with anti-inflammatory properties, has demonstrated potential in regulating inflammatory pathways. However, its impact on cardiovascular activity in the context of hypertension remains unclear.

Dysbiosis of gut microbiota is well established in coronavirus disease 2019 (COVID-19). While studies have attempted to establish a link between the gut commensal () and COVID-19, the findings have been inconsistent and sometimes controversial. The intestinal microbial abundance information of COVID-19 patients was acquired and analysed from GMrepo database.

Improving gut dysbiosis and impaired gut-brain axis has been a potent therapeutic strategy for treating myocardial infarction (MI). Geniposide (GEN), a traditional Chinese medicine extract, has demonstrated substantial cardioprotective properties post-MI. Nevertheless, the effect of GEN on gut microbial, gut-brain communication, and its potential mechanism remains unclear.

Objects: Taurine exhibits protective effects in the context of cardiovascular pathophysiology. A range of evidence suggests that hypertension activates inflammatory responses and oxidative stress in the paraventricular nucleus (PVN), elevating the arterial tone and sympathetic activity, while it induces gut-brain axis dysfunction in the context of hypertension. However, the mechanism underlying taurine's anti-hypertensive effects via the gut-brain axis remains unclear.

The pathogenesis of attention-deficit/hyperactivity disorder (ADHD) has not been fully elucidated. Gestational hypertension could double the probability of ADHD in the offspring, while the initial bacterial communication between the mother and offspring has been associated with psychiatric disorders. Thus, we hypothesize that antihypertensive treatment during pregnancy may abate the impairments in neurodevelopment of the offspring.

Diets rich in taurine can increase the production of taurine-conjugated bile acids, which are known to exert antihypertensive effects. Despite their benefits to the heart, kidney and arteries, their role in the central nervous system during the antihypertensive process remains unclear. Since hypothalamic paraventricular nucleus (PVN) plays a key role in blood pressure regulation, we aimed to investigate the function of bile acids in the PVN.

Article Synopsis
  • Chronic kidney disease (CKD) leads to serious health issues and there's a need for new treatments, particularly involving the use of probiotics to improve gut-microbial interactions impaired by CKD.
  • The study evaluated microbial differences in CKD patients and tested a probiotic in mice, finding that it could reduce kidney dysfunction and inflammation while enhancing gut health.
  • The beneficial effects were linked to butyrate from the probiotic acting through the GPR-43 signaling pathway, suggesting new therapeutic possibilities for CKD management.

Gut microbiota is well-established to regulate host blood pressure. Diosgenin is a natural steroid sapogenin with documented anti-inflammatory, antioxidant and antihypertensive properties. We aimed to investigate whether the antihypertensive effects of diosgenin are mediated by the microbiota-gut-brain axis in spontaneously hypertensive rats (SHR).

Gut dysbiosis and dysregulation of gut-brain communication have been identified in hypertensive patients and animal models. Previous studies have shown that probiotic or prebiotic treatments exert positive effects on the pathophysiology of hypertension. This study aimed to examine the hypothesis that the microbiota-gut-brain axis is involved in the antihypertensive effects of curcumin, a potential prebiotic obtained from Curcuma longa.

Kidney cancer is the third most common malignancy of the urinary system, of which, kidney renal clear cell carcinoma (KIRC) accounts for the vast majority. Runt-related transcription factors (RUNX) are involved in multiple cellular functions. However, the diverse expression patterns and prognostic values of RUNX genes in kidney cancer remained to be elucidated.

Exercise (Ex) has long been recognized to produce beneficial effects on hypertension (HTN). This coupled with evidence of gut dysbiosis and an impaired gut-brain axis led us to hypothesize that reshaping of gut microbiota and improvement in impaired gut-brain axis would, in part, be associated with beneficial influence of exercise. Male spontaneously hypertensive rats (SHR) and Wistar Kyoto (WKY) rats were randomized into sedentary, trained, and detrained groups.

The hypothalamic paraventricular nucleus (PVN) plays crucial roles in central cardiovascular regulation. Increasing evidence in humans and rodents shows that vitamin D intake is important for achieving optimal cardiovascular function. The purpose of this study was to investigate whether calcitriol, an active form of vitamin D, improves autonomic and cardiovascular function in hypertensive rats and whether PVN oxidative stress and inflammation are involved in these beneficial effects.
