Sodium-Directed Crosstalk Between Immune Cells and Lymphatic Vessels.
Review in Current hypertension reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purpose of reviewThe role of the lymphatic system in clearing extravasated fluids, lipid transport, and immune surveillance is well established, and lymphatic vasculature can provide a vital role in facilitating crosstalk among various organ systems. Lymphatic vessels rely on intrinsic and local factors to absorb and propel lymph from the interstitium back to the systemic circulation. The biological implications of local influences on lymphatic vessels are underscored by the exquisite sensitivity of these vessels to environmental stimuli. This review is intended to highlight the role of sodium within the local environment in mediating lymphatic and immune cell interactions that contribute to changes in function and disease progression. RECENT
findingsWe discuss evidence that accumulation of interstitial sodium modulates lymphatic growth, pumping dynamics, and permeability of renal lymphatics, which involves activation of sodium potassium chloride co-transporter (NKCC1) in lymphatic endothelial cells. These recent findings complement observations that sodium activates immune cells via the epithelial sodium channel (ENaC), leading to the formation and accumulation of lipid oxidation products, isolevuglandins (IsoLGs), in antigen presenting cells, which in turn promotes T cell activation and vasculopathy. In addition, we will underscore the physiologic relevance of altered interplay between immune cells and lymphatics in the sodium avid state that characterizes kidney diseases and consider how sodium accumulation in the interstitial compartment of the kidney modulates the lymphatic network and the interactions between renal lymphatics and activated immune cells. Finally, this article calls attention to persisting knowledge gaps and stresses the need for additional studies to identify salt-sensing mechanisms, including sodium-activated immune cells and lymphatic endothelial cell interactions, for targeted therapeutic interventions in the setting of renal disease.
