Purpose Of Review: Salt-sensitive (SS) hypertension and its associated kidney damage have been extensively studied, yet proper therapeutic strategies are lacking. The interest in altering the metabolome to affect renal and cardiovascular disease has been emerging. Here, we discuss the effect and potential mechanism behind the protective effect of lysine, an essential amino acid, on the progression of SS hypertension.
Recent Findings: We have recently demonstrated that administering lysine in an SS rodent model can control the progression of hypertension. Both the animal and pilot human studies showed that lysine can efficiently inhibit tubular reabsorption of albumin and protect the kidneys from further damage. In addition, we conducted multilevel omics studies that showed increased lysine conjugation and excretion, leading to the depletion of harmful metabolites and an increase in useful ones.
Summary: Lysine's twofold action involves both mechanically flushing protein from proximal tubules to shield the kidneys and initiating metabolic adaptations in the kidneys. This results in a net positive impact on SS hypertension. While further research is necessary to apply the current findings in clinical settings, this study offers some evidence suggesting that lysine supplementation holds promise as a therapeutic approach for hypertensive kidney disease.

Background: Hypertension is a leading risk factor for the development of Alzheimer's disease and Alzheimer's disease-related dementia (AD/ADRD), which is closely linked with cerebral vascular inflammation and dysfunction. We previously found that high-salt-treated Dahl Salt-Sensitive (SS) rats displayed blood-brain barrier (BBB) leakage, astrocyte activation, neurodegeneration, and cognitive impairments. CD14 functions in the Toll-like receptor 4 (TLR4) complex to initiate proinflammatory signaling events in response to LPS.

Background: Early vascular aging (EVA), manifesting as increases in central arterial stiffness and BP, is associated with cognitive impairment in humans. EVA and cognitive impairment occurs in Dahl salt-sensitive (DSS) rats consuming a normal salt (NS) diet with an advancing age. Quercetin (QRC), a flavonoid with anti-oxidant, anti-inflammatory and senolytic properties, previously shown to reduce salt-sensitive hypertension in DSS.

Myocardial dysfunction is a crucial determinant of the development of heart failure in salt-sensitive hypertension. Ferroptosis, a programmed iron-dependent cell death, has been increasingly recognised as an important contributor to the pathophysiology of various cardiovascular diseases. This study aims to investigate the role and underlying mechanism of ferroptosis in high-salt (HS)-induced myocardial damage.

Context: Women versus men have more Salt sensitive blood pressure (SSBP) and higher stimulated aldosterone (ALDO) levels, suggesting that their increased SSBP is secondary to a relative hyper-ALDO state. Contrariwise, men versus women have higher sedentary ALDO levels.
Objective: Thus, the present project was designed to address the question are women versus men in a relatively hyper-ALDO state?
Methods: 363 women, and 483 men were selected from HyperPATH cohort to assess the potential underlying mechanism for observed sex differences.
