Abstract

Animal studies show that high-salt diet affects T-cell subpopulations, but evidence in humans is scarce and contradictory. This pilot study investigated the effect of a 2-week high-salt diet on T-cell subpopulations (ie, γδ T cells, Th17 cells, and regulatory T cells) in five healthy males. The mean (SD) age of the participants was 33 (2) years, with normal body mass index, kidney function, and baseline blood pressure. In terms of phenotype, there was an isolated increase of CD69 expression in Vδ1 T cells (P =.04), which is an early activation marker. There were no statistically significant changes or trends in any of the other tested markers or in the Th17 or regulatory T-cell subsets. The increase in CD69 was strongly correlated to increases in 24-hour urinary sodium excretion (r =.93, P =.02). These results of this pilot may motivate the use of longer dietary salt interventions in future studies on salt and adaptive immune cells.
