T helper cell balance dictates salt sensitivity and hypertension. Salt-resistant rats with regulatory T cells are protected from high-salt diets, unlike salt-sensitive rats that develop hypertension.
Area of Science:
- Immunology
- Cardiovascular Physiology
- Renal Physiology
Background:
- High-salt intake is linked to hypertension and pathogenic T helper 17 (Th17) cells.
- Hypertension development under high-salt conditions is observed primarily in salt-sensitive (SS) individuals.
- The role of T helper cell polarization in salt sensitivity remains unclear.
Purpose of the Study:
- To investigate whether T helper cell polarity determines salt sensitivity and hypertension development.
- To elucidate the mechanisms by which salt-resistant (SR) rats are protected from high-salt diet-induced hypertension.
Main Methods:
- Cultured splenic T cells from SS and SR rats were exposed to hypertonic salt solutions.
- SS and SR rats were fed either a control or high-salt diet (HSD) for 4 weeks.
- Systolic blood pressure, aortic ring relaxation, T helper cell polarization (Th17 vs. T regulatory [Treg]), gene expression, and transcription factor enrichment were analyzed.
Main Results:
- Hypertonic salt induced Th17 differentiation in SS rats and Treg differentiation in SR rats.
- HSD induced hypertension, endothelial dysfunction, and Th17 polarization in SS rats.
- SR rats remained normotensive with Treg polarity and protected from HSD-induced hypertension.
Conclusions:
- T helper cell polarity is a critical determinant of salt sensitivity and hypertension development.
- Anti-inflammatory Treg cell polarity protects against high-salt diet-induced hypertension.
- Targeting Th cell polarization may offer therapeutic strategies for salt-sensitive hypertension.

Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
